Title: Yeast producing a 'peachy' flavor?
Post by: yso191 on June 04, 2013, 11:59:46 PM
I just posted in the Commercial Beer Review section about a reaaly good IPA by Terminal Gravity.  On their website they mention the 'peachy' flavor comes from the yeast.  Does anyone have an idea which yeast they use, or what yeast produces peachy esters?  Any oth info about their recipe would be great too.  I loved the residual sweetness, which left me wondering what Crystal grain they use...

Chico comes across as fairly peach-y (though I'd say more apricot-y) to me sometimes.

I think S-05 has a faint peach aroma for a clean strain.

Some english strains through an enormous amount of peach when stressed, even at low to mid-60s. Not sure if that applies to any of the WL/WY strains.

Conan yeast used by the alchemist for their heady topper is known to enhance peachy flavors...truthfully I don't pick up on it too much.

I've noticed this too.

Sounds like I need to give S-O5 another try!  Thanks!

What temp are you guys fermenting at to get the peach?

I've noticed it @63, very subtle.  In other words not from going too warm.

Low 60s

I fermented a faux German pils recently with US-05 in the low 60's and it had something that I could place, not off, but just not "clean" if you know what I mean. Perhaps that's the peach/apricot thing it produces. Or maybe it's just esters because it's an ale and not a lager because I got something similar when I did a cream ale with WY1450 also. Could be my water also...

US-05 is one of my go to yeasts and it does have a few fruity esters that I have noticed from time to time - peachy/apricot is one at the lower end and slightly banana at higher temperatures.  It is good to hear that this is not just my palate, but others experiencing this, too.  I have used this yeast in a broad range of temps, even down into lager range with success.

In comparison to most other ale yeasts S-05 is "clean".  I have found it inappropriate for pseudo lagers, so I just stick to making regular lagers instead, since I have fermentation temperature control.  German ale yeasts (WLP011 or Wyeast1007) may work better for pseudo lager fermentation.
