This time I decided to try WLP005 (British Ale Yeast). Within 24 hours things looked good; blowoff tube was bubbling and SG was dropping. However...

    Efficiency Math Questions

    Thanks for the replies, everyone! Gnome and doug282cz both hit what I was looking for - SG*Vol is an approximation of "total sugar" that I can use to calculate efficiency, and I don't even need to use my mash volume to figure out theoretical yield because multiplying my grains' PKL values by...
