Well, I boiled it down to the final volume and took a reading. I get 13 ppg (based on original weights and volumes) which compares well to the 14 I got from the estimates. The original estimates were using the final barrel volume and the original dry grain amounts, so it's on target.
I just added the golden syrup. The wort now tastes like wort. It actually tastes like a liquid bran muffin. I'm chilling the wort down now. I am going to krausen it since I already have a batch of ale going in high krausen and 2.5 qts of beer isn't worth tearing open a whole sachet of Nottingham. Will probably ferment it right in the pot.
Oh, I was reading 2.5 gal.; 2.5 qts is indeed a small batch. Are you taking pictures?
