Interestingly, when the UK went into lockdown in 2020 (and pubs closed), the demand for beer dropped low and brewers brewed so little that it caused a Marmite shortage in the supermarkets.

[@jsccs1]

That's actually pretty interesting. I'm surprised that you weren't experiencing beer shortages, as we were here in Canada.

[@brett_norris]

I'm surprised that demand dropped in the UK for beer. When lockdown hit, Americans drank HARD. Maybe the UK did as well, but with other alcohols? It would be an interesting comparison.

@@brett_norris a fair whack of bottles/cans sold in supermarkets here are imported brands, whereas domestic beer is more likely to be sold in pubs. traditionally, pubs here would be part owned or tied to a specific brewery and mostly only allowed to sell beer from that brewery. this is less common now as "free houses" have become dominant, but its still the case for many pubs

There was an issue with the Marmite production plant in New Zealand about 10 years ago, which lead to no Marmite being made at all for over a year. Some stockpiled what they could and people started selling jars of the stuff for hundreds of dollars on the internet.

I was out of veggie stock for my stew, but then remembered this video and had an idea. I browned some tomato paste, deglazed with a shot of brandy and enough water to cover everything, then added some soy sauce and maybe a teaspoon of yeast.

That was really interesting. Thanks. For any novice interested in trying yeast spreads here's some pro tips from a veteran Vegemite eater. The butter goes on the toast or bread FIRST. Marmite is slightly sweeter than Vegemite and l believe that English Marmite is different to the Australian one. A little vegemite or marmite goes a long way! The aim is to spread it as thin as is humanly possible. From memory about ½ teaspoon will do for a slice of toast. Remember. It. Is. Not. Nutella.

Adam, I’m a home brewer, so I know a little about this. If you really want to do home made yeast extract, brew an unhopped ale. I’d use celery seeds to mildly bitter the beer, but have an agreeable flavor in the yeast. The ale would be to sweet, but probably drinkable with a dash of bitters, or used in a beer cocktail. Maybe mix with tomato juice. But the flocculated yeast should be perfect for yeast extract. For around $60 in ingredients you would yield 50 12oz bottles of very strange celery sweet ale, and wild guess 2+. Jars of sweet yeast extract. A few years ago, I made a chi spice cream ale, so the wort was seasoned with cinnamon, ginger, clove, nutmeg, cardamom, and star anise. So I made yeast extract with chi spice yeast. It was a wonderful sauce on fish, chicken, and pork. It also played very nicely with roasted root vegetables, and winter squash. To make my yeast extract I just use my immersion circulator at 48c for the first 3 hours the 50c another 22.. the two times I tried with hopped beer it was to bitter to use. Hope that was useful, cheers 🍻

As an Australian who’s a fan of both Vegemite and Marmite (in that order), the way we put it on toast is butter first, preferably melted. Thickness of spread varies on the person but I’m a light spread guy as i feel the less intense taste combined with the melted butter is the best balance

I believe you've missed the actual reason why there's "yeast extract" on so many ingredients lists. That natural umami flavour from the yeasts available to us in the store is just the start! Yeasts can be genetically programmed to taste like just about anything. In Europe this will be labelled as "natural flavouring". I watched an episode on it from a TV show about food production in my country, and it was eye opening and crazy interesting. They had quite some trouble to find a yeast flavouring producer willing to participate. As the food industry apparently rather not explain that not all generic engineering is created equal. And they really don't mind sticking with the assumption that most of us now have that the "natural flavouring" in our strawberry yogurt comes from strawberries. When in reality it's yeast programmed to taste like a fruit.

​​@@kaka3630Uhm, because it's delicious? What are you even asking?

[@Plumpy4]

A brewer's two cents: To harvest more yeast i would suggest making a starter of brewer's yeast, not baker's. They are the same species, saccharomyces cerevisisae, but the brewer strains are more capable of consuming sugars and will resist to alcohol production. As a cheap source of food for the yeast go with malt extract (either liquid or in powder) to make some wort. Inoculate the wort and let it ferment in a warm place, shake it often, decant every 1-2 days and repeat the process in larger amount. You should end up with a lot of yeast in a few days. Then just evaporate slowly, you could leave it on a hot radiator for a few days. Autolysis will occur even below 50°C, it happens naturally in beer at room temperature. Yeast extract is fantastic, here in Switzerland we have Cenovis, which is just like Marmite.

FWIW, if you want to try growing your own yeast again, I suspect you'll have a better time if you: use a more complex sugar (like your beloved malt extract syrup if it doesn't contain preservatives), and use a taller than wider vessel. That stink was likely an excessively-aerobic lactic fermentation that produced all kinds of stuff you don't want. I do yeast starters in erlenmeyer flasks (which aren't common in the home kitchen, of course, but a tall mason jar could do the trick too). Also worth investigating that yeast have a reproduction phase (which actually *IS* aerobic) before the fermentation phase. Your brewer friend from recent videos could probably lend some wisdom/information.

[@ljakeupl]

@@cavemancamping you're thinking of when you move the cooled down wort from the boil kettle to the fermenter. pre-fermentation is when you want to add all the oxygen you can. once fermentation has started you want to be sure to minimize any oxygen exposure, preferably none of you can do closed transfers. any oxidation after fermentation can cause off flavors.

[@scoates]

Replying to myself: you can also try adding a yeast nutrient if you want to stick with simple sugar (that will be much cheaper). The yeast probably runs out of nitrogen the way you tried. A certain other community uses tomato paste as a yeast nutrient (which doesn’t carry through the… uh… purification process), and might actually be interesting in a yeast “sauce” (look up “tomato paste wash” if interested).

[@scoates]

@@ljakeupl I suspect @cavemancamping means before natural carbonation, in which case, the bottle fermentation will use up the oxygen unless it’s *really* excessive. (This is why bottle conditioned beers tend to age well compared to forced carbonated examples.)

[@kennyholmes5196]

When you refer to complex sugars, out of curiosity, would mixing flour into the water instead of sugar be a good idea?

[@scoates]

@@kennyholmes5196 that will add some nutrients, sure, but most of the sugar in flour is locked up in the starch and needs an enzymatic (normally) process (via an ingredient such as malt, “diastatic power”) to convert the starch to sugars that the yeast can consume, so you won’t actually get a lot of growth out of the yeast, without yeast food, and you will get a starchy mess.

yeah, the whole point of toasting bread, and the reason you toast the bread, is to use it as a vessel to move large amounts of butter into your mouth. when making cheese-on-toast, be sure to add butter to the toast before the cheese, as it helps with the malliard reaction, the browning you want, on the cheese. crumpets, are basically just MASSIVE butter-sinks, So there is no point in buying them at all if you only ever eat them dry. they are designed first and foremost to get butter into your mouth as efficiently as possible. so if you don't like butter, or you avoid it for some reason, like I do, I'd suggest not bothering with toast or crumpets, just put your olive spread, like i do, on something that tastes nice by itself, like malted-bloomer loaf, which I also eat, instead of white bread.

[@El_Hornio_II]

One thing I wanna mention about Vegemite is that while it is roughly similar in terms of colour compared to Marmite it's not as similar in a few other categories, for one it's more stiff in terms of consistency and also you would not want to square up to just dipping your finger in and having a taste, it has an incredibly salty flavour so much in fact that it can be applied to an ulcer and it'll heal, you also would not want to put your nose anywhere near it just smelling it would make your eyes water, it's still amazing on toast (with some butter of course)

[@kizi86]

@@richardparadox163 yep was really surprised he didnt mentioned SousVide, because, as you say, its the goto thing for holding set temps. i even use my sous vide machine to "break in" my vape e-juice that i make, makes it so much easier to mix everything if i have it set at 39°C, and that shortens the wait time from 3-4 weeks down to 1-1.5 week while it "steeps" if i have it in the sousvide bath for 4-6 hours at first.

[@Grilnid]

I guess sous vide works well because whatever you put inside can never overshoot the temperature of the bath you set. He does mention that at some point, when the yeast starts "waking up", it also heats up quite a lot, and while a circulator may be good at heating water up slowly and consistently, it's way harder to get a big volume of water to cool down if you overshoot that temp. And who cares about that after all, this never happens when you cook meat or fish or whatever else. The yeast being the sensitive little creatures that they are, I'm afraid even a mild temperature overshoot might ruin and kill the whole batch, so that's a caveat. I'm not ruling it out entirely, but it might not be the miracle solution to that issue too

[@chiblast100x]

@@Grilnid That's hardly an issue. You just use a large enough water bath to allow sufficient surface evaporation while the yeast is doing it's metabolic heat up. If the water is at or over temp, a circulator will reduce or kill the power to it's heating element while still pumping the water through so it won't provide additional heat. So long as the water has enough surface exposed to cooler ambient air it'll lose energy to the air and drop temp which will cause the yeast to do the same to the water and if the whole system isn't able to maintain the set temp, then the circulator kicks back on it's heating. The only tricky parts are maintaining enough water at temp until the yeast finishes then covering the entire bath after so it doesn't keep rapidly evaporating.

I'm 76 years old, so it was a while back; however I do remember three details you may have missed. 1) You have to boil that sugar water before you add the yeast or bacteria could kill the yeast. 2) You have to bubble air through the yeast. 3) You have to make sure the air is sterile. We used an aspirator on a water faucet, to make a partial vacuum. On the air inlet side, we pulled the air through sterile cotton, which (amazingly) filtered out the bacteria. You probably want to use some kind of pump that doesn't waste water, but I recommend the cotton.

I knew this day would come. My Mom let me try Marmite when I was a kid and I’ve been hooked for life. I highly recommend trying it on a bagel with cream cheese (apply on top of the cream cheese) I find the butter toast method is so hard to spread unless you apply too much butter first. You can use even less marmite than you would with butter and it tastes amazing. My buddy from college hails from Australia and to this day we’ve had an on going “battle” of Marmite vs. Vegemite. I tried to convince him to try vegemite on a cream cheese bagel and he was perturbed by the idea. Though, there’s something about the umami yeast flavor of a bagel that perfectly mixes with the rich tartness of cream cheese already and when you apply marmite on to that it create a literal umami sandwich. If there are any NY bagel shop owners out there, please add this to your menu, It will catch on as much as Lox. Funnily enough my mother and I love marmite and my two brothers prefer vegemite. My dad, a saint of a human, gets physically upset at the sight of both hahaha I hope you like it.

Sous vide may be a way to maintain the temps at 50 C.

I get a pretty good layer when I have done hard cider at home but always tossed it out.

[@chiblast100x]

Using the yeast from wine, mead or cider making may have the exact opposite problem of using beer yeast. All those typically have a fair amount of sugars that are indigestible to the yeast that will remain in with the yeast when you go to process it. That could mean a reduction with enough of a sweet taste to overpower the savory taste.

@@chiblast100x As far as I know beer contains more unfermentable sugars than ciders and wines (and possibly meads) so I doubt this would be a problem. More likely that concentrated flavours from the apples or grapes would cause problems than the sugars but they may also add interesting flavours.

[@garyyencich4511]

Instead of an electric blanket might I suggest using an Instant Pot with a sous vide setting?

The Instant Pot maintained the temperature very tightly over 36 hours of culturing and yielded great results. It seems like it might be ideal for this application as well. Instead of the pressure dome I used the optional glass lid to keep an eye on things but probably any lid would do.

There's an interesting experiment combination that might actually give you a combination of homemade ingredients. Like other commenters said, malt extract syrups as the food for a highly-flocculant yeast (Wyeast London Ale) would get you a malt liquor of sorts with no bittering and a pile of yeast on the bottom of the vessel as that yeast drops out of suspension on its own. Use the yeast to make yeast extract, but then toss in a vinegar mother colony as in earlier videos you've done and make malt vinegar. Could even reduce that down into a malt equivalent of balsamic vinegar.

Homebrewing has some pretty good process to multiply yeast. Also, yeast for homebrewing can be found in special shop and might be much cleaner than the bread yeast that you can buy at the store. Dry yeast is easily accessible but liquid yeast might be even better and with dozen of yeast strain available, it may have a good impact on the final taste too.. Now for the experiments! hehe

I imagine that's the only economical use case of homemade yeast extract. It's far easier to buy marmite online and have it shipped to you than trying to make it yourself with yeast you bought at the store. Seems kind of silly. But if you already have a crap ton of yeast slurry you'd normally dump, might as well try to reduce it into a nice food additive.

Allow me please, and pray take no offence, to highlight the disservice you performed on the Marmite-on-toast-eating contingent of the British isles. One does not cut the thinly spread black gold with the butter. One applies a generous coating of butter to a hot slice of toast and then, and only then, applies a thin coating of the Extract. A slice of dry, mature cheddar is an optional accoutrement to the affair that I would personally recommend.

Something I experimented with that might be worth exploring if you like yeasty flavors and aren't gluten intolerant is mixing up some dough, allowing it to rise/proof longer than you would for making bread (I let it go about twice as long), then making it into boiled dumplings instead of baking it. The resulting dumplings had a bit of a different flavor than the blandness I usually expect from boiled dumplings, but given that I'd tossed them into soup I'm not sure how much of that is just the confirmation bias of me going in assuming it would work.

Home brewers and breweries often make Yeast Starters, which typically do not contain hops. It's easy peasy. It's much more effective if you have a stir plate and an Erlenmeyer flask. Instead of using dry malt extract like you would do if you wanted to "train" the yeast to eat the more complex maltose, and maltotriose sugars that they will get from a barley grain mash you could feed them simple dextrose which is cheaper and very easy for the yeast to eat. A brewer would boil the water, add the sugar and then after 15min or so cover and cool the liquid before transferring to the flask, adding the yeast, covering with foil and putting on a stir plate for 2-3 days. You could decant off the liquid and do this all again to make more and more yeast, but eventually you'd need a bigger vessel to get more yeast.

Amateur mead maker here. I think the reason your yeast died out before eating all the sugar was because they were nutrient deficient. Sugar satisfies the caloric requirement of yeast, but in order for them to grow up big and strong, they need a source of nitrogen. This is the same problem I face when making mead. Honey has lots of sugar but very little nitrogen. So you have to supplement the nitrogen source somehow. Options include diammonium phosphate (aka DAP), or proprietary blends of nutrients (Fermaid O and Fermaid K are popular). Additionally, the funky smell probably came from bacterial contamination. Yeast are easily outcompeted by bacteria or mold if your equipment is not properly sanitized. Hope this helps. Side note: I have a jar of old yeast in my fridge from my last brew and have been wondering what to do with it. I might try some homemade marmite.

[@Piboon11]

Thank you so much, Adam. Your experiments on yeast extract are very interesting and, also, enjoyable. I have been using Marmite, especially in beef stew, since an English friend introduced it to me in May 2022. Beef stew will never taste its best without Marmite. Fun watching you, too. Cheers, XXX

[@Zestric]

I suspect the yeast you were trying to grow didn't get enough oxygen if your pan was completely covered by the clingfilm and therefore they started fermenting your sugar into alcohol which slows down yeast reproduction fairly quickly. If you are trying to grow yeast just to get more of it (basically farming yeast cells) you would be better of doing it under aerobic conditions (meaning access to oxygen) where they use their normal metabolic pathway which allows them to get much more energy and avoids producing the alcohol that will slow down and then kill your yeast.

[@OttoStrawanzinger]

Thank you! I was hoping somebody would post it. For yeast to grow, it needs oxygen. The original inventor of modern industrial pressed yeast, Ignaz Mautner Markhof, also didn‘t just use sugar, but basically a mash of barley malt and rye flour that would form lots of yeast foam on top which would then get skimmed off. This kind of mash provides better nutrition to the yeast than just pure sugar would.

[@Zestric]

@@OttoStrawanzinger Yes you're right but the oxygen alone in this case would already help it work significantly better. If you wanted to increase your yield you would want to use something like barley syrup or another kind of unrefined sugar product to give the yeast all the amino acids and minerals they can't get from refinded sugar.

[@davidonfim2381]

I really doubt it got to the point where oxygen was an issue at all. The biggest problem, I think, is the lack of additional nutrients/minerals in the water. When making alcoholic beverages, yeast is able to grow and reproduce because the hops/grapes/honey/etc all have additional chemicals that are able to maintain the growth of the yeast.

[@Zestric]

@@davidonfim2381 Well Adam said it started producing alcohol which I think would inhibit growth sooner than yeast can run out of necessary nutrients.

[@kb2vca]

It's relatively easy to grow your own yeast by amending what Adam did. I would look for a flask or a gallon glass carboy and add say, a quart of water. To that quart I would add about 4 oz of either liquid malt or dry malt extract . Completely dissolve or mix the malt extracts and to that I would add a pack of beer or wine (or bread yeast - For the latter I never use fast acting and I believe the bulk yeast has no emulsifier). You want to constantly agitate the liquid to aerate this and after about 3 days the biomass of the yeast will have increased immensely. Because you are aerating the yeast you are encouraging them to reproduce rather than produce alcohol and so you can after a few days allow the yeast to settle and then add more water and more DME or LME and repeat. The living cells are going to be more massy than the dead cells and so you can "wash" the cells by filling the carboy with distilled or spring water (chlorine free) and allow the cells to drop to the bottom of the vessel. On top will be water, beneath the water will be be dead cells and beneath the dead cells will be yeast.

Exactly. Marmite is delicious. I am fed up of watching Americans try it on KZbin and pulling a disgusted face, because they invariably spread it on like Nutella, and pulling a dumb face is thumbnail clickbait.

If your first taste of salt was someone pouring a teaspoon of it directly on to your tongue, you would instantly decide that salt is revolting and should never be eaten. I didn't like it as a young child, but at around the age of 10, thanks to my dad, I saw the light, so if anyone wants to experience an epiphany, here is THE recipe for introducing yourself to the delights of it: 1. Butter a slice of HOT toast, then spread a thin layer of Marmite on it. 2. Butter a second piece of toast and place it on top of the Marmite, butter side up. 3. Place a soft poached egg on top. Knife and fork. Pepper to taste. Enjoy! The combo of the salty Marmite and the runny egg yolk is a marriage made in heaven.

As a meat-eater that loves exploring vegan cooking, marmite/vegemite works amazing as the base flavour for vegan gravy. Become a favourite of mine. Vegan or not, just great gravy. Yes, it has similar umami+salty like soy sauce or stock. But diluted marmite really does taste like beef gravy or like a beef stew. Not beef as a piece of steak. But long cooked, braised beef flavour. So it mainly tastes of beef, a little of mushrooms and something of its own. All together yummy. I've seen some australians put a thin layer of vegemite on their steaks before putting it on the barbie sort of like a rub (though I don't think this is a super common thing to do.

@@ub3rfr3nzy94 true enough, you have to watch out for "gadget creep" cluttering up the kitchen

​@@ub3rfr3nzy94 I don't know about that, unlike with many really gimmicky gadgets there is allot of shit you can do with a sous vide machine and they're pretty straight forward to use. Like honestly barely any harder then literally boiling water, and they have a bonus of producing really idiot proof results too. Most of them are actually quite small too since they work by just clipping to an existing pot or tub. Most of them are basically a stick maybe a foot tall and like four or five inches wide.

@@ub3rfr3nzy94 I said the same thing until I got a sous vide... now I use it 5+ times a week, I have started preping "dinner bags" for several days at once (Huge time saver) and just "drop um in" a half hour or so before I start my rice/pasta/starch and by the time that's ready I have one bag with my protein and one bag with my veggies, very little effort and wonderful flavor and lots of good stuff still in the veggies cuz it never got too hot and the meat is Sooo tender...

I don't eat it all that often, but I absolutely love Marmite. Unfortunately, since the pandemic started it's been really hit and miss as to whether I can find it in stores in my part of Canada. At first it was because all the pubs shut down in the UK and as a result UK beer makers cut way down on production, so there wasn't enough "waste" yeast for Marmite to keep their production up. Lately it's more because of supply chain problems that are affecting pretty much everything imported from other countries.

During the early pandemic it was hard to source Marmite even in the UK. Although interestingly they have an "extra mature" luxury type variant and that was still fairly easy to find. I guess it was made from pre-pandemic stock?

@@lordhoot1 There's a limited edition Dynamite Chili, which is Marmite with chili. It tastes just like Marmite, but it warms up your gums. :D

Great video! Adam, I was always taught that yeast doesn't like metal. You might try growing your yeast in a glass bowl using only two cups of warm water and one eighth of a cup of sugar. I have not tried growing yeast like that. I have been using part of a bread recipe as a starter to grow yeast. It's refrigerated between uses. It has extended the life of a jar of yeast.

Isn't it only true with active metals, like aluminium, zinc and tin that covers other metals? Stainless steel should be fine here, as it does not corrode -> does not release ions into water.

@@alissamedvedeva5614 I use glass, ceramic or plastic bowls when making anything containing yeast.
