Title: Dry yeast fermentation temp
Post by: thirsty on August 29, 2010, 04:32:55 PM
What is the preferred temp to ferment US-05 and S-04? I haven't used dried yeast in a long time.

I run 05 from the high 50s to the mid 60s.

Just used it for the first time in years myself.  I fermented at 68 and got quite a bit of fruity "ale" flavors... more akin to the English Ales  I have been brewing.  There may even be a tiny hint of clove to it (notice it in one or two burps, but not in the flavor while drinking).  I am not sure if that was due to temperature or if there is more than just S-05 strain lurking.  (I am using in a new keg system and chose a neutral beer to show any flaws in sanitation or cleaning out the soda residue I may have)

WIth that in mind, if you would like a more subdued ale, I would go colder than 68 for sure.  If you want more fruit flavors, do not go above 68!

Good luck

US-05 in the low 60s for me, usually let it raise to the mid 60s. It ferments well in the high 50s, very clean. I personally dislike S-04. It has that English character but tastes one dimensional to me. The only problem with US-05 is the first gen takes forever to drop out. Not flocculative at all.

I also like to ferment S05 in the low to mid sixties and have had great success in the upper sixties as well.  I like S04 as it lends better mouthfeel and ferments about the same.  S05 ferments out pretty dry...great for west coast ales whereas S04 is good for most English examples.

 I also use S05 in my American BW which really works out well in that it is like the Energizer Bunny...it keeps going...and going...and going.

US-05 gets tart at 59 for me...some say peach. Clean but tart.
