Degassing Mead: When, Why and How

[@pderham26]

I love how many wholesome small channels there are about mead making.

[@PaginaDeRedSocial]

I love that the Harvard course "Food Fermentation: The Science of Cooking with Microbes" led me to this channel.

[@alexanderbeeser6070]

not to nitpick, but twice you said that the yeast take oxygen and convert it to carbon dioxide. This fundamentally misrepresents what fermentation does. The C02 from fermentation comes from pyruvate. Glucose to pyruvate ( C6 to 2 X C3, glycolysis) and then the decarboxylation of pyruvate ( C3 to C2 + C02, pyruvate decarboxylase) to make acetaldehyde followed by its reduction to ethanol. The stuff on degassing however was good.

[@stinkymart3173]

I use a cocktail spoon for my 1/2 and 1 gal batches, it fits in the mouth of the carboy, reaches to the bottom and is easy to sanitize

[@chrischaney3082]

If anyone's new to this, and just got one of those drill bits, DO NOT put that into your mead 48 hours into pitch and fire that drill up! Ever seen that little kid science fair project with the baking soda volcano? Yeah, that. Instead, before you put the bit into the drill, just use the bit like a spoon and GENTLY give it a LITTLE swirl. See how that foams up, wait for it to die down, then give it a little MORE of a stir. Like MMM says here, you're not trying to oxygenate, so you really don't need to make some kind of Whirlpool Charybdis scenario in the carboy. Work your way up in stages. And if you can, do it in the bathtub juuuust in case.

[@treyb387]

This is exactly what my mead is doing. I've racked it twice for secondary, and it's still bubbling. I think it just needs degassing. It slowed down to a standstill, but then when I took it out it picked up so I realize that CO2 is still present in the mead and needs to escape. I'd rather not use tablets to stabilize it, but let it degass naturally if I can. Thanks for the tip!

[@kb2vca]

A couple of quick comments. Half the weight of the sugar in your mead is transformed into CO2 so that is a lot of gas. There are a couple or three good reasons to degas DURING primary fermentation and not after the active fermentation has ended. 1. That amount of gas (if you are fermenting 3 lbs of honey 1.5 lbs of gas is produced at normal pressure) dissolved in the mead puts great pressure on the yeast cells (think what it feels like to dive 100 meters under water), That pressure can stress the yeast and stressed yeast will produce all kinds of compounds most of which do not enhance the flavor of your mead. 2. CO2 when dissolved in the mead produces carbonic acid and carbonic acid is an acid and that will drop the pH of the mead. Honey at the best of times has no chemical buffers to control pH so with the addition of carbonic acid you can find that the pH of your mead will drop below about 3.0 and at that level fermentation CAN stall. 3. The presence of CO2 in the mead will enable all kinds of particles to remain in suspension and their presence in suspension means that your mead will be cloudy. Not a major problem unless you are looking for a bright clear mead but if that is indeed what you are looking for then allowing CO2 to remain in solution (and the CO2 will saturate your mead depending on ambient air pressure and temperature) will make obtaining a non hazy mead a real challenge.

[@hatchertiger]

Would the above rational also apply to beer and wine? Asking for a friend. :o)

[@southernstacker7315]

I have a 5 gallon batch thats about 4 weeks in. I used a drill stirring tool when I first started the the fermentation but I haven't touched it in about 4 weeks. The Bubbling has slowed down but it still bubbles every couple minutes. I was planning on transferring it into a big mouth 5 gallon carboy at week 6. Do I need to stir it again before I start the secondary? It's in a Fermenting bucket now and I haven't opened it in 4 weeks. What would you do? I really enjoy the videos and go to them daily for tips. Thanks for sharing you knowledge.

[@ManMadeMead]

I wouldn't stir it up after the primary! You don't want to add more oxygen at that point. Generally you don't need to do a ton of degassing after the first like 7 days of it's life.

[@CaptnDirt]

Get a MityVac brake bleeder from auto parts store. Cheap and works great!

[@Combat_Pyro]

What about using the vacuum line from my foodsaver that is designed to draw a vacuum on mason jars? I bet that would do it quick!!! Lol

[@Mitchasauraus]

Great Channel with great info! My first batches were made a week and a day ago and are just simple mead they are under air lock with a light swirl every couple of days as a matter of fact I degassed yesterday and it was letting a wonderful and slightly alcoholic smell thru the airlock! Once I hit a month then if the air lock activity has settled mostly and the gravity normalizes I'll rack into secondary and go from there. Hope to be as natural as I can with the whole process.

[@bobu5213]

Wouldn't a magnetic stirrer be much better? Or am I thinking too much like a lab setting lol

[@raimonds6719]

thank for your video. I will ask the reason why in some recipes to make mead they bring to the boil honey and water?

[@ManMadeMead]

People used to do that do mix the honey easier. You don’t really need to. It was also used to pasteurize (kill off) and wild yeast.

[@andrewweaver8363]

Should degassing be done after it gets down to the final gravity? Or during the fermentation?

[@ManMadeMead]

I do it mostly during the fermentation! Maybe a little after but you don’t want to go too crazy and introduce a lot of oxygen!

[@trevorsocia2300]

I'm surprised no one brought up MEA's (mead explosion/explosive accidents). I've had this happen more than once in the past and it isn't any fun, both do to the clean up and to the now wasted mead/must. You absolutely need to be gentle when using a wine whip to degas!! Start slow and build speed after a few minutes or it can foam over and create one heck of a mess. The bubbles start out large but will get smaller and smaller as you whip; this process could potentially take 15-20 minutes depending on how much it bubbles. Just takes practice but be sure to take your time. Also, as for what can be used: I work in a hospital and have even used a 60cc syringe to degas (press the tip into the rubber bung to seal, pull the plunger all the way out slowly, watch it bubble, then repeat over and over). I've also watched videos of people converting air pumps into degassers, or FoodSavers.

[@ManMadeMead]

You definitely have to be careful. It all comes back to the important idea of having patience when making mead haha.

[@Combat_Pyro]

Foodsaver is what I’m thinking. We already have one that has a vacuum line. It wouldn’t take much to adapt it to a bung and vacuum that sucker (no pun intended) down flat.

I just realized I could use my vacuumed sealer.

[@HomesteadDIY]

Once I learned about degassing mead, I started doing it and still do so, but I'm reading more these days that it may not be as important as some believe. Part of the reason is the mead is already degassing itself (all that bubbling going on in the airlock) also that it may have more to do with staggered nutrient additions than anything else. If you're following a SNA protocol (or adding fining agents for that matter), then you should degas, otherwise it may not be necessary (or so I've read). I'm still degassing as I typically follow a TOSNA 2.0 and I use fining agents to clear my mead, but it seems it might not be the critical step once thought. I used a paddle in my drill to degas the mead, running it slower than if I was aerating it.

[@ManMadeMead]

RuggedHomestead Yeah the airlock does let it naturally aerate so I feel like degassing really just has to be done if the mead itself is still pretty carbonated. Also if you’re trying to speed up the process of bottling and aging. It just all depends on how much carbonation you want, some people want some and other don’t! I’ve never heard of the TOSNA 2.0 stuff so I’ll have to check that out.

[@mylesmejia6854]

Have you done a video on how to tell when your Mead has spoiled or something of that nature?

[@ManMadeMead]

Myles Mejia I haven’t ever done one over that, but that’s a good video idea!

[@GhoulishCop]

It’s actually pretty hard to ruin mead. Most times time is your answer-just let it age. Even If a bacteria has infected your mead it might not be a complete loss depending on the type. With that said, I did end up having to throw away a cyzer because I had failed to wash my apples and it got infected. I tried aging it out but after a year it tasted horrible and since it was only a gallon I figured I had sunk enough time into it and poured it down the drain.

[@kb2vca]

I have to say that I am surprised. Fruit ain't grains and mead ain't beer and it can be incredibly difficult to spoil a mead. Once you pitch the yeast the yeast will dominate any volunteer bacteria or indigenous yeast and the cultured yeast will create an environment that prefers the cultured yeast and dis-prefers any other organism. It's possible that the cyser tasted bad for other reasons but it is hard to imagine that spoilage would be a cause. Of course, stressed yeast and poor choice of honey (East Coast buckwheat) can create problems but it's hard to infect a mead, in my opinion.

@Man Made Mead Hey there!! So I am quite confused on what to do regarding Degassing. I intend to do a primary fermentation without degassing, but would like to complete this process during the racking phase from primary to secondary fermentation (in-between). Though, what I am confused about regarding Degassing is: Wouldn't you introduce oxygen if you racked your mead into an open bucket or container and, wouldn't you add oxygen to your mead by stirring it up?....which, from what I know, is bad? just confused on the proper way to Degass without worrying I messed up and allowed the mead to be exposed to the elements and or oxygen.

[@ManMadeMead]

So you can degas at any time if you lightly stir. Just opening your fermenter won’t introduce a ton of oxygen. The only way to add too much oxygen is by violently stirring your mead after the primary.

I have seen many tips and videos of using the wine degasser you mentioned (power drill attachment) in the oxygenation process. Does this actually oxygenate the mead or does it instead release all the oxygen already in the mead? Btw I really enjoy your videos and, as a beginner mead-maker, I find them very helpful.

It definitely helps to oxygenate the mead. Generally any stirring will give the mead some oxygen. The more vigorous the better before the fermentation starts!

i am 2 weeks into making mead and have never drank mead before so i am all kinds of excited and wanting to experiment with the 2 gallons that i have in production. thanks for the vid on anti carbonation. end game for storing the mead i want to go the whole 9 yards of putting it into regular corked 750ml wine bottles. would you recommend the vacuum wine seals over corking? 2nd question. i want to make it with carbonation like beer too. should i force carbonate it latter on or would it be fine to natural carbonate it like a craft beer. i understand natural carbonation leaves a sediment at the bottom that should not be drank, but what i don't understand is the longevity of it? mead gets better over a period of time very much like wine. would that carbonation and sediment be a problem?

[@chriswiltse2281]

i understand that you are not carbonating your mead, but wanted your opinion anyways. totally cool if you don't as-well.

[@ManMadeMead]

I don’t think carbonating your mead will impact the flavor over time. You can absolutely force carbonate later on or just let it naturally go through the process. It seems like you want a lot of carbonation and generally the natural carbonation process will not give you a huge amount (atleast not as much as a beer or a soda). The vacuum seal over wine bottles is great and I would highly recommend doing it! Don’t be able to rack your mead to get rid of that sediment, while carbonation can be nice the overall flavor of the mead is more important and leaving a lot of sediment can cause issues with that.

[@km-bo3zx]

Just know, that regular wine bottles should NOT be used when you are bottle carbing. You need to use beer bottles or champagne bottles, which are thick enough to withstand the pressure from carbonation.

Aaron Shreve So you can’t add any more sugar or honey until after the fermentation is done otherwise the yeast will just pick up where they left off.

Also, is it bad to do a little bit of degassing during primary fermentation during the off days of staggered nutrient supply?

[@ManMadeMead]

It’s totally okay (and preferred) to degas mostly in the primary. If you do it later than the primary you just want to be sure to not introduce oxygen into the mead because that will ruin in. I would degas during the primary and add your fruit into the secondary as soon as you move it over!

You absolutely need an airlock or something to keep stuff from getting in your mead. I would suggest to either buy an airlock or to use a balloon and poke a hole in it so the air can escape.

[@Murlockingqc]

Also, when I go and carbonate my mead before bottling.. what's the difference? Am I reducing the storage lifespan ?

[@ManMadeMead]

If you stir lightly you will not add a significant amount of oxygen to a brew. So you don't risk it going bad. Degassing is really only necessary in the middle of fermentation because the yeast get stressed out when there is excess CO2 in the solution. While they do expel it, they can be overwhelmed by it at the same time. When you force Carbonate with CO2 you are good! CO2 doesn't hurt the mead, but straight up oxygen will!

I wouldn't worry about degassing it, it should be doing that on its own. I would definitely rack it off the sediment (this will also degas it a little).

First, thanks again for your great channel. Question: When you say to let the mead recover 8-12 weeks after de- gassing and not to do anything else, does this mean you should not bottle right after after de-gassing? I had planned on de-gassing a mead right before I bottle and then let it recover before bottling. I assume de-gassing is like "bottle shock" so why not do it right before bottling? FYI, this mead is a Mango-Habanero I adapted from the Mead Challenge you guys did and the sip I had is awesome. On the same subject, I am thinking of not de-gassing to allow for a little light carbonation. Have you made a carbonated Mango-Habanero? Might be good but this just seems like it should be a warm, still mead. Thanks again.J

[@ManMadeMead]

You can bottle after degassing! You just want to make sure that it's fully degassed otherwise you will get some carbonation/excess CO2 in the brew.

[@ErikHoevenberg]

From what you have said in your videos I get the impression that you are not aware that yeast will not start to convert sugar to alcohol if they have plenty of oxygen. The fermentation process is something that yeast does to stay alive when no oxygen is available. I assume that oxygen is introduced in the first place to help out the yeast a little before they get to work. A lot of the tips I have seen seem to have the same goal, increasing the odds of a successful batch by making the yeast comfortable. If you did know this, oops my bad.

[@ManMadeMead]

Erik Hoevenberg You’re definitely right! I already knew this and have a whole video about preparing yeast for the must and giving them everything they need including oxygen. But you’re definitely right.

[@aaronshreve3335]

Super helpful.

[@guilhemane]

The oxygen in the mead is not used in fermentation! Oxygen is not turned into CO2! We don't want oxygen all throughout the primary! Yeast can respirate (breath/eat) in two ways: 1) aerobic respiration, where oxygen and sugars are turned into carbon dioxide and water, and 2) anaerobic respiration, where sugars are turned into carbon dioxide and alcohol. This anaerobic respiration is alcoholic fermentation. Given the presence of oxygen, yeast will prefer aerobic respiration because it is easier for them and more efficient. The reason we want oxygen in the beginning of a fermentation is so that the yeast can eat, multiply, and build solid, healthy colonies before getting into the alcoholic fermentation. In the primary fermentation we want to generate alcohol, so we don't want to oxigenate the brew throughout the primary like you said, but instead we should just oxigenate at the very beginning. The presence of oxygen throughout the entire primary would be dangerous because it would also allow for other things like bacteria.

[@amyprice327]

Yeast doesn't use oxygen for fermentation, that's purely an anaerobic process.

[@FusionDeveloper]

I shouldn't give recommendations or advice yet, but, I would think that if you ferment on a surface with an incredibly mild vibration (like from a fan or desktop computer running or something like that), then that would help to de-gas during fermentation. I'm not talking about something that creates visible turbulence on the surface of the mead. If you are fermenting under your computer desk, maybe put your computer on a piece of wood and have that wood extend over to where your mead is, so that it gives is super gentle insignificant vibration. If it shakes loose 0.1% to 50% (random numbers, not based on any data) of the bubbles, that's still something more than nothing. I'm not recommending running power to something to achieve this, but if you can recycle vibration that you are creating as a bi-product of something you always run anyway, it may be worth experimenting with. Also, I recommend you DO NOT put a fan near your fermentors in a way that will possibly blow air into your fermentors.

I like to hook my trusty Electrolux and vacuum it out.

Uh oh, i might have bottles waiting to explode, good thing i already planned to unbottle them and sulfite treat it.

If you put a bunch of sugar in them before you bottled you might have issues!

@@ManMadeMead I use potassium metabisulfite to end fermentation before bottling
