Removing Apple Taste (Acetaldehyde) From Beer

[@henriknordgren2400]

Did the same a few weeks ago - One cup of water, 3 ounce disolved table sugar and a few grams of voss in a apple smelling/tasting lager. Cleaned it out nicely!

[@mongrel_97]

you guys have great production value. you deserve way more subscribers.

I did EXACTLY this to clean up diacetyl and it worked pretty well. I still had some toffee flavor, but I'm attributing the remainder to the hop and malt flavor profile. I had concerns with warming up, de-carbing, and possibly oxygenating the beer after kegging, and some of that may have happened, but it was still drinkable.

Voss Kveik is so versatile!!! Love that stuff!!

[@Lopdog0218]

Thanks for the video; I do have a question regarding what was said about not putting the flask directly on the stove. is that correct even if I have a pyrex that's designed to withstand direct heat? Thanks,

[@Teh509]

Explain borosilicate flasks in labs.

[@charlespartak2435]

i have had this happen to a few beers in the past. up until now i was always under the assumption that the beer was lost and only good for drain cleaner,lol. i poured those beers into a fermenter and was going to re-kick start it and make it more like a Belgian or maybe even add some brown sugar and turn it into an abbey style . i'll have to try this next time. thanks

[@TheApartmentBrewer]

Great video! These tips are fantastic, this should work pretty well for diacetyl and other fermentation-derived off-flavors as well I would think

Guys what is more recommended in case like that one, yeast slurry or packet of dry yeast for starter purpose ? I had similar problem but with diacetyl and I would like to try this shot

[@codyway7424]

Would've been good to see a gravity reading before and after.

[@Rtstrider]

I've used a whole crushed tablet of Sodium Metabisulfite per 5 gallon keg when that happens. It's an immediate fix and way less trouble. Try that and lemme know your results! I do it all the time with my adjunct lagers

[@ClawhammerSupply]

Tell me more… What does this do / how does it fix the problem?

[@Rtstrider]

@@ClawhammerSupply I don't know the how lol I found this mentioned in a reddit thread and tried it. Just add a crushed tablet into a filled keg, purge with Co2 a few times, shake, purge again, then taste. It's almost immediate everytime I've done that. Now that may be way overdosing. As an experiment I tried this with cream of three crops since any off flavors will show in that brew. Everytime I brew that with minute rice and quick grits it's loaded with acetylaldehyde regardless of yeast strain (tried us-05, wlp840, Charlie's fist bump). Campden in the keg fixes it and makes it very drinkable! Try it and let know your experiences :) I've tried adding this to a cup of boiled water and adding that to the keg. I've also tried just crushing the campden and adding that directly to the keg. Results were the same. Now my kegs were already chilled and carbonated

[@10-4-Rubber-Ducky]

Have you tried bubbling Co2 down the beer out line? Acetaldehyde is volatile and Co2 is good to remove a lot of it.

[@jonburlew302]

How long after pitching did you keg this beer that resulted in acetaldehyde? I'm trying to keg a beer for an event 11 days after pitching yeast. It's a 4.7% pale ale. Think it'll be ok or apple city? It's in my basement at about 64 degrees and very little activity after 3 days. Just put a blanket around it

[@ClawhammerSupply]

Just sample the beer before kegging. You’ll be able to tell.

[@MrJordonmcgee]

Did you purge that keg to get all the co2 out before pitching the starter yeast? Or was it still carbonated?

[@ClawhammerSupply]

Purged it.

[@simonschrickel3783]

Had a kveik ale pressurefermenting for 3 weeks now at 28 to 32C. And it still tastes undone. Still have the yeast left, should i take it out of the fridge and repitch some of it(making a starter). With the high temps coming up i have no other yeast on hand.

[@NWsmallbatchBrewing]

Nice tip. This was more than just the tips .... :-)

[@jaytomten3782]

After brewing with Voss a few times I feel it is not a great yeast for hoppy beers. it seems to really knock out a lot of hop flavor and aroma.

[@vertharion694]

maybe is the temp? I don't like using Kveik for hop yeast because of the high temp, most the flavor and aroma are too volatile

[@cabinvibeetsystore9094]

Thank you 🙏

[@fdk7014]

Pairs well with getting out of bed.

[@kyriakoshadjipandeli1436]

What can we do if we already bottle it? The flavour came after bottling 😢

[@chamiboy1]

give it time (weeks) at ferm temp

[@kingquesoIV]

is the acetaldehyde flavor gone simply because you effectively purged through the solution with CO2 ( yeast made more co2 which purged soln) that would also explain why the hop flavor is gone.

[@ClawhammerSupply]

The yeast metastasize whatever compound it is that causes the apple flavor. But they definitely make more co2

[@jamesturek665]

Calling BS on the water bath ( but I like it). Those erlenmyer ( sic) flasks are made to take the heat, so don’t fret the heat vs water bath. Jim ( chemist)

[@cabinvibeetsystore9094]

New sub! Liked 😊🙂❤️

[@fifis101]

So it changed the beer but at least fixed the off flavour.

[@thegingerpowerranger]

Could the Apple smell have come from the hops? And you fermenting it again has driven off all the hop flavours taking the apple with it?

[@wesfox1712]

West Coast IPA, I see you Eazy-E

[@brendancaves2139]

Goofy after shower beers, lookin good Emmet 🤘🖕😁

[@engelspielur]

Is that you Zack Snyder?

[@Paxmor]

I think Apple is a bad descriptor. It tastes much more like the smell of wet hay. As a horse boi I would know.

[@graymalkin26]

Good idea that apparently worked...WTF is up with all the off topic posts.

[@ClawhammerSupply]

Lot's of spam on the old KZbin lately. We just cleared them out.
