I ended up adding 4.5 lbs of malt extract and 1.5 lbs of corn sugar. I mashed a bit high at 154 degrees, so I thought adding the sugar would help dry it out a bit, but 1.5 lbs in a 34 gallon batch isn't going to make much difference (was 35, but lost a gallon to hot break). My O.G. was 1.049, which according to beersmith means I had 82% efficiency. Right now the whole batch is just starting to bubble away. The hop additions using the mesh bag worked really well. I had no trouble using the Therminator. I used 4 Whirlfloc tablets and the wort came out very clear. A total of 18 oz of Amarillo hops were used, which thanks to hops direct only cost me about $11. Overall a good brew day. I'm looking forward seeing how this batch comes out. Since I have 34 gallons fermenting, I should end up with close to a full barrel of beer. Hopefully it turns out well.
