Dry yeast alcohol tolerance?

[HGBM.SOO]

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.
