FLAWED WINE Blind Tasting - Master of Wine tastes Wines with added Aromas.

[@artoftasting]

Great video Konstantin, and nice job identifying these compounds! They are added at a low level, i.e. the same quantity you would expect them to occur in real wine. Not easy to pick up the aromas at that level. Please note geraniol is a positive floral character (often described as rose-like) contributing to the flavour profile of many aromatic varieties including Muscat, Gewürztraminer, Riesling, Torrontés. Geraniol is a terpene released during fermentation, from an odourless precursor present in grapes (especially skins). The geranium leaves flavour you describe is due to a different compound (2-ethoxyhexa-3,5-diene) and always considered a fault. Overall I think you made an informative and entertaining video out of the tasting kit!

[@KonstantinBaumMasterofWine]

This was cool to watch. I’m a chemist as well as a general nerd. I love how much I learned from this video. Thank you for the video

[@CAE38IDS]

This was absolutely amazing! I work at a brewery in Seattle and we do sensory training very similar to this- we spike the samples to varying degrees and we learn to identify them. I did overall “good” (83 overall) but it is definitely something I have been working on and it’s great to see some of these wines characters and the overlapping ones were super interesting (acetaldehyde, isoamyl acetate, diacetyl, vanillan) The Brett character is one that I have brought up several times in discussions of doing more advanced/specialized sensory training. I’ve been working towards becoming more and more involved in our barrel aging program.

[@plapperkfr2045]

Can you share the chemicals you spike the samples with? I'd be really interested in participating (or if everything else fails, creating) a tasting for sensory defects in beer (and I doubt you ship to Europe :)). I studied chemistry for around 15 Years, so I'm confident to create comparable (and non-lethal :D) samples given the chemical and the concentration :)

[@teosoderholm96]

all except tca are overlapping in a brewery, 4-mmp presence in hop is massive and a lot of work is made to extract more thiols nowadays, geraniol the very same...

[@plapperkfr2045]

@@andreassvensson228 Yes, I'm aware of that :) Nevertheless, it'll mighty helpful to create that (wanted or unwanted) taste, so you can acutally confidenly talk about what you taste and discuss whether it should be there or not :) "I think it tastes.." becomes much more of a learning opportunity when it's pronounced "It tastes of ... - because I put 50ppm in there!"

As a chemist and wine nerd this video was super interesting, what a great idea! I'd love to do a tasting like that, i think it would be very educational. Fun fact: in the university where i did my bachelor's the 2nd year organic lab experiment to teach us about esters was making and distilling isoamyl acetate 😁

[@ShoeAlmighty]

I wish I could thumb this down twice.

[@DMJKraft]

Another informative video, Konstantin. I struggle to identify Diacetyl and Geraniol in blind tastings, and have a long way to go on this one... I watch your videos every day over lunch. They are the perfect length for me. Excellent content, fun and well informed. I have also recommended your videos to colleague at the WSET in London. Thanks. David Kraft from the UK.

Thank you!

[@bor4oborisov]

Congrats. It’s was really really good video. The thematic is great and the demonstration very practical. I am living in Bulgaria where everyone makes own wine and take it as the best in the world. I am familiar with some of the aroma, because home wines have it all. An hour ago I made blind tasting of home winemaker’s wines on the street of Melnic( an iconic wine Town/region in Bulgaria). Believe me or not I have tasted half of the wine mistakes in the book. I really enjoyed the video and wish to have more educational videos like this.

[@jeffnichols473]

Really fun video, thanks! I’ll definitely try to buy one of these kits. One interesting compound I came across recently is dimethyl sulfide, which has aromas of tomatoes. It’s something that I’ve encountered in really hot weather Syrah here in Southern California, but can also show up in coffee beans from some regions (I think Kenya, for example).

[@philipohmes9395]

This takes me back to years ago, when I was making true fruit wine vinegars from fermenting fruit wines. After the fruit wines were made, filtered and aged for a year in glass, I added the bacteria to convert the ethyl alcohol to acetic acid. The results were aged for 90 days and then tasted with the fruit wines they were made from. Another less expensive way fruit wines are made is to take crushed fruit pulp and add it to white vinegar. The fruits I used were: red grape syrup (often found in brewery stores to make a wine), strawberries, dark cherries, raspberries, oranges, and lemons. Later I came across a Broker selling Swiss Chocolates and is company in Switzerland also made and sold true fruit wine vinegars. So these specialty vinegars are also available in specialty food shops and quite expensive. It was a fun hobby for that time. On a more scientific note...a graduate student at Louisianna State University did an extensive study about the fermentation of sugar with all of the other compounds found in the fermented liquid. Thereafter how these complex compounds then became vinegar. Tan, San Chiang, "Vinegar fermentation" (2005). LSU Master's Theses. 1225. digitalcommons.lsu.edu/gradschool_theses/1225 Always much to learn. .

[@MichaelG1986]

Very interesting video. I'm a very amateur wine taster, but it was interesting seeing you go through various aromatic compounds. The compounds reminded me of my organic chemistry classes at university years and years ago.

[@KonstantinBaumMasterofWine]

I hope thats a compliment ;)

[@MichaelG1986]

@@KonstantinBaumMasterofWine It is. We had a brief laboratory exercise that included flavors and fragrances that included complex esters and ketones. I recognized some of the nomenclature.

[@pilsplease7561]

TCA is not detected by so many people, im so sensitive I can smell it from an open bottle 15 feet way. They tasting room staff at the last winery I worked with used me to test corked bottles cause they couldnt detect it and needless to say ive experienced enough cork taint to last me my entire life at this point its not pleasent.

[@timyork6150]

Thanks for that Konstantin. I find that most of those "faults" can add to the complexity of wine, if discreet and in balance. Exceptions to that are, of course, TCA and, for me, vanilla. As regards Brett, I ran a poll on UK, US and Australian wine lovers' sites and found that in all three, a majority of consumers welcomed modest Brett as an element of complexity. Yes, even in Australia, although with a much slimmer margin. If I were doing it again, I would now add a French language site where I would expect the tolerance to be even greater.

[@teosoderholm96]

research has done in italy with regards of blind tasting, and all groups (modest drinkers, expert, and non drinkers) preferred light brettanomyces character in tuscan red wine

[@ericthompson3255]

Really interesting video! I'm going to have to study these compounds more in depth. I was aware of their potential presence in wine, but knew little of the science behind them, so now it's time to get learning!

[@joshleedom8722]

As a beer nerd first, I'm glad I was able to guess Bret before you mentioned it. Also, I've had a French Pinot with Bret in it before, and it was disgusting. Thanks for the video!

[@KonstantinBaumMasterofWine]

Very cool!

[@fermento]

Did you laugh when he missed diacetyl?

[@fermento]

For beer, usually found when racked too early, or if primary fermentation is done at Lager temperatures (below 18°C) and the temperature has not been later raised (starting often around 2-5 gravity points above final gravity). The diacetyl rest is usually 3-4°C above fermentation temperature, e.g. 18°C, for a few days while the yeast cleans up the diacetyl.

[@DavidRaccah]

Super interesting video! I would have expected one of them to be VA, that is a classic flaw - especially in white wines - did I miss it??? Be well!!!

[@jamieharkar915]

That was the Acetaldehyde

[@comesahorseman]

Once again, thanks for taking the hit for the rest of us! 😅 And, yes, TCA is indeed nasty!😬

[@joaopalhoca928]

In the 2nd sample, if you smell passion fruit, it would be 3MH acetate. 4MMP gives you a more fresh new cut grass smell. The 3MH gives a more sweet citric smell.

[@KonstantinBaumMasterofWine]

4MMP is assiciated with Box tree, passion fruit, & black current aromas according to multiple sources, including UC Davis and the Australian Wine Research Institute. 3-MH and 3-MHA also smell of passion fruit but 4MMP is the most potent aroma.

In the beer world, diacetyl manifests as a cream corn aroma.

[@BeauKpad]

I first learned about diacetyl working in a German-style brewery-restaurant in the 90's. When the beers got too old they tasted of butterscotch.

[@oxvaldus]

Fantastic idea💡!!!!

[@karlinggard]

Wow, this was interesting! One thing I find particularly useful by reducing wine down to its aroma compounds is that it helps us help people who are new to wine figure out what they're actually smelling. For example, a friend detected what likely was diacetyl and vanillin in an oaked Chardonnay. In WSET language we'd describe it with butter, pastry, vanilla and toast, but she said it smelled like a croissant. Which makes complete sense! A toasted crust with a buttery dough inside. People associate the same aroma compounds with different things, and it's useful to know what they are so we can establish a common language, which makes it easier to communicate what we experience a wine tastes of.

[@petarvelickovic9342]

Interesting tasting with Konstantin Baum​ Major aroma aromatic compounds. This is a very interesting topic. I would love to see a video on fruit aroma compounds in wines. For example why Pinot Noir smells of red fruit, and why Cabernet Sauvignons smells like dark fruit.

[@franciscoalvarez1189]

I find bret really attractive, as long as it keeps at lower levels as possible, and stays only in the nose (not in my mouth). I found that in wines aged in oak casks for years.

[@angusmcmillan8981]

Thanks once again, and no I didn’t know all the aromas. But about half certainly. I read that wine can have TCA cork taint even when the bottle isn’t closed with a cork, because the bacteria that produce TCA can take hold in the plumbing/ containers at a winery. True? Please adjudicate.

[@jacksonwatkins6431]

Brettanomyces is all the rage in the beer world, not just in Belgium.

[@fermento]

Eh... It's used, more a craft beer thing though and still is a minority use.

[@fermento]

Certainly for dry styles like Saisons and other aged beers it has had a comeback among some nano breweries and passionate homebrewers. I did hear the best Berliner Weisse traditionally used Brett but it is no longer produced in Berlin.

[@markiangooley]

I at first thought of those flavor-added wines sold occasionally at Aldi here in the U. S.: wine with fruit or chocolate flavor added, usually. Very different!

As to speak serious, could you do something of a kind next time, but adding the name of a substance on the screen.

Anyway, I would definitely like to dive down this topic again! Thanks! (Sober today)

Very interesting video, especially since many of these so called flaws can actually be beneficial, or seen as beneficial.

Is (too much) acetaldehyde a common thing in viognier? I often pick up on a quite musty note that I don't particularly enjoy in those wines, and it sounds like it might just be that.

[@KonstantinBaumMasterofWine]

Maybe it is also associated with Viognier - not sure.

[@teosoderholm96]

it is associated with stressed/incomplete fermentation, acetaldehyde is a step further of alcohol degrading, so it's same smell that you can smell from someones breath while hungover or drunk

Brett is associated with poor hygiene in the winery, no other excuse can save it. Getting rid of Brett is hard and only those deep cleanses with special chemical foams that cost an arm and a leg can deal with it because Brett can survive in the tiniest of crevasses. I don't see how Brett can be something good, that smell has been associated with French wine and most of the French people I've met hate when people say that, they really don't like their wine being associated with a barnyard smell or manure but it has become a thing.

why are u doing it like this? only relevant if you do a triangle tasting, and you don't specify dosing rate, also everything you had except tca and acetaldehyde (maybe even that in small amounts, american lite beer has some acetaldehyde on purpose to accentuate "freshness"), does and can enhance wine in right amounts

[@KonstantinBaumMasterofWine]

Well... not really sure whether a tasting is only relevant if you do it in a lab...

[@Ildskalli]

Super interesting video! I knew about all of them except the lactone, I didn't know it was responsible for the coconut smell and taste of American oak. Acetic acid was absent, though, and I think it's an essential compound for the set. I must say that I don't like the clickbait title very much. I know it's pretty much essential for youtubers to use clickbait, but I think you could do better here, as many of the compounds aren't necessarily wine flaws. Something like "Master of Wine tries wine training kit - wines with added aromas" might be more truthful, and also interesting.
