RIS Attenuation
Saturday, September 27th, 2008Hey all,
I transferred my Russian Imperial Stout the other day, and after a month it only attenuated about 63%. I think its really too high and am thinking about adding more yeast to kick up another ferment.
OG-1.092
FG-1.032
Yeast: Wyeast 1056 with half liter starter.
I realize I used too small of a starter. Im really just lokking for what I can to right now to bring down that FG. Any suggestions would be good, Thanks.

EDIT: This was one of my first attempts at Partial Mash because i still am not able to make AG batches yet.
6# dark DME
1# Chocolate Malt
1# Black patent
.5# Rosted Barley
2# Caramel 120
1# Pale 2-row
and 1# Corn Sugar
I mashed at 154 for about 90 min. After punching the numbers in Promash I got about 40% efficiency.
I also realize that there is way too much Caramel 120 in there. the mouthfeel of my sample was crazy! but the tast was the best thing i’ve ever made. it was Chocholaty and roasty and delicious.
Brewrunner, do you think that US-05 would be the best way, or should i try to stick with 1056? Thanks!
