This subject is being touched on in another thread, but let's discuss it from another angle. I've often wondered if I could put together a $20 beer. My last few brews have been extracts, and when he rang up my BIAB grains, hops and yeast for my Nut Brown, it was $25 and change. So the brew store and I looked into brewing my cheapest batch possible. They have a price cut at 10 lbs of grain, and I buy hops and yeast for every batch. I don't buy anything in bulk. We put together a recipe that only costs $18.10 for 5 gallons. That's 10 lbs of 2 row and 1 ounce of Nugget, two additions. The yeast is S-05. I brew 5 gallon batches, and as I said earlier, I buy hops and yeast every recipe. I don't buy 50 lb grain bags either.
