This stuff is a beast. Went from 1.046 to 1.006 in 6 days.
Used it with my first partial mash adlib recipe with stuff i had originally bought to make a pumpkin beer.

Anyone using this yeast ever get subtle fruity flavors peach/apricot maybe??. I tasted the sample not sure if i like it but its definitly interesting. I alternate between thinking i taste the “cat piss” of cluster hops that people talk about or a subtle pleasant fruity flavor. I know that sounds weird cat piss or pleasant but i took like 15 sips and couldnt figure it out. Beers only 6 days old so im still hopeful time help…

My experience with us05 is its pretty clean. In fact, its a pretty good choice for mock lagers, if you can keep it on the low end of its temp range. Give it some time.

3

What temp did you ferment at? I think 05 is pretty clean if you use it right.

4

This is probably the cleanest dry ale yeast out there. I can’t think of any major problems I’ve had with it.

5

66-68. Its likely not fruit flavors from yeast maybe wishful thining? I think its something with the cluster hops, The more i tried it the more i got the black current/catpiss taste they are known for.

6

Fermented warm it will give off some esters. I use it in the 50’s routinely for lager-like results.

7

I usually try to keep it around 64F. very clean yeast. I always have some on hand.

8

i have experienced peach flavors in a pale ale i made. Fermented in low 60’s. Like 62F if i remember correctly.

After doing some more searches its not just me that got peach/apricot flavors from us05. I read this regarding pretty much the same question i asked. “Peach is sulfur-based flavor/aroma. Sulfur containing compounds are produced from stressed yeast and most commonly seen when fermented cool”

What i dont get is why some get the peach flavor and others get a clean finish. Any ideas? Aeration?

if you want the peach stank, throw this in, but it might be weird with a pumpkin ale: http://www.whitelabs.com/beer/strains_wlp655.html

i’ve had good results with an 05 for a week, then cherries and the belgian sour mix. if you want a dessert taste, maybe coffee and the sour. might turn out well.

I’m one of those who posted about us05 doing some odd things for me at lower temps, over on HBT. I took a gamble on it again, but maintained 67 in my ferment fridge and found a perfectly clean beer with the hop punch the Chico strain is known for. I’ve used it several times since then and never lower than 67f, and its been great. I know a lot of people have reported great ferments with us05 anywhere from high 50’s to lower 60’s… I’m just not one of them.
