I'm going to use their U.S. West Coast Ale M-44 tomorrow for a Blind Pig IPA clone, fermented around 64F. I'll let you know how it goes.I had a pack of this left and decided to take the risk on a pale ale this past Sunday. It is likely the last time I will ever use Mangrove Jack's yeast. I hope I can actually get this one to attenuate lower than 1.016. Fingers crossed...
Sorry for taking so long to reply - my last 3 evenings have been busy. Anyway, if you still are fermenting your beer, check out the following "Fermentation Observations" from the yeast description at Rebel Brewer:
Quick to start, this strain will linger through primary and secondary fermentation, achieving final gravity after 2 weeks. Krausen will be dense and creamy, occasionally voluminous. Patience in conditioning will reward brewers with a nicely dry, yeast -neutral beer.http://www.rebelbrewer.com/shop/dry-yeast/west-coast-ale-dry-yeast-m44/
The M-44 was recommended to me at my LHBS for PA and IPA, as cleaner, more hop-focused, and more attenuative than US-05. He was saying that US-05 attenuaes to about 76% and M-44 to around 78%. Patience my friend!
As for being a quick starter (per the article above), I'm not convinced since after rehydration and held at 64F for 30 hrs and then up to 65F, my beer took a full +48 hrs to form a decent krauesen. It does appear to be a slow, steady fermenting yeast. Cheers and good luck with your brew.
