Hi.

Recently, i brewed imstout. This wort OG was 1.108
I used 2 pack of us-05. But 2 weeks after wort FG was 1.046..
I did aeration at 2 times (before in the fermenter and after primary at 16 hours)
I want to brew high alcohol imperial stout..(abv13~15%)
I wonder alcohol tolerance of mangrove Jack's m44 and m42!

Anybody give me advice :)

We need more details like the recipe. What size batch? What temp did you mash at if all grain? What temp did you ferment at?
US-5 can handle well over 10%.

Batch size 12L
Single infusion mash at 67c 70min and mash out
at 76c 10min..
Yes . All grain and added 8~9% candi sugar.
Ferment at 19c 2weeks.
Efficiency was 75%...:(

Maybe check out Fermentis S-189. It's a lager yeast, however.
