Hey everybody, I'm new to partial mashes and was wondering what a typical effieciency for a partial mash is, so I can convert my extract recipes to PM. I've been using the rule of thumb 1lb grains = .75 lbs LME, but I'm wondering if I'm overstating the amount of fermentables I'm extracting from the grain. All I'm doing is throwing a few pounds of pale malt into the brewpot along with my specialty grains, in a big nylon grain bag. I steep in about 2 gallons of water for 45 min at 150 degrees, sparge with a quart of 170 degree water. Is it safe to assume I'll get roughly a certain amount of fermentables out of this or do I need to get a hydrometer and start calculating my brewhouse efficiency? I'm not particularly concerned with exact figures, I just want the beer to taste good
