I've been on the fence about biotransformation, it sounds cool and all, but is it really real? Cosmic Punch by Omega seems to release a ton of tropical aromas. It is supposed to unlock thiols through biotransformation ... and for all intents and purposes it appears to be true.

I used a blend of Mosaic, El Dorado and Loral. Boom! Probably the most hop aromatic beer I have ever brewed.

That's good to hear. I ordered some and some Calypso to go with it. Have you gotten any sulfury/diesely flavors from the beer? I've had two beers made with it (Triptych Thiol Trip Tech Vol 1 & 2, both with Cosmic punch and Phantasm) and while they had a lot of flavor and aroma there was a definitely diesel kind of flavor to it.

I hope not! This is still in fermenter taking samples of zwickle. Blown away by aroma I won't blown away with diesel. No sulphur in aroma.

Glad to hear some good results with it. I have a pouch sitting in my fridge that I haven't gotten around to using yet. I'm not sure if I want to try it out with the same recipe as the last IPA I brewed to get a decent comparison to something fresh in my memory, or if I want to go all-out with extra big flameout and dry hops along with some grapefruit zest.

I remain skeptical, but... as a chemical engineer, I also understand how magical chemistry can be.  Especially organic chemistry.  So, I guess I'm staying tuned until I might one day participate in some blind tastings of my own to know for sure.  Seems interesting if it's real.  *Eyes still slightly squinted...*

There's a really good podcast on the MBAAon the yeast and thiols. Check it out. it goes into way more technical stuff than I'm going to be able to post here

[mabrungard]

Very interesting.  Good to know that some yeast are more adept at that conversion!

Using a blend of cryo pop and other cryo according to the charts in the survivable booklet I achieved the same type of result.  Of course, there's no way to compare with what you got,  but I can't imagine it could get much better.

[majorvices]

Those cry hops are sooo expensive and can be hard to get. Yeast is comparably much cheaper and can be reused.

From everything I have read, biotransformation is a real thing, in that there is measurable biochemistry happening. But what's measurable via lab equipment isn't necessarily measurable to a palate. In other words, I think the question isn't, "is it a real thing?" but rather, "does it matter?"

Maybe it does, maybe not. The beer might be different...but different and better aren't the same thing. I am also skeptical. Homebrewers are like beer consumers in that they are always transfixed by the shiny new object (process-wise).

Side note: Omega yeasts are mostly, if not all, GMO. Majorvices, if this was a commercial batch, I'd be curious to know how well that is received by your customers. GMO-anything is generally a third rail in the brewing industry.

[majorvices]

It was a 7 bbl batch. I'll definitely post impressions once they come rolling in. i jumped the gun a little by posting after sampling the zwickle but i can tell it's gonna be an amazing beer.

When were hops added to maximize biotransformation?

[redrocker652002]

Having never used liquid yeast and wondering out loud, would this work in a hoppy IPA?  Any recipes out there that you all think would be a good fit for this?  Any special ways it has to be handled?  If I am over my head as a newbie, please let me know, but I read the description on morebeer and it sounded pretty good.

WP and near end of fermentation.

Keep in mind that bioxformation only works with certain yeasts and hops.
