Notes:
------
OG is gonna be a bit low since i'm using too much brown malt which can't convert well.

Pre-Boil Gravity: 1.034 @ 134 degrees = 1.048
OG: 1.063

Pitched a cake of WL East Coast Ale that had just finished fermenting a smaller batch of this instead of the Burton Ale since I forgot to make a starter of the Burton and with an OG of 1.063 this definitely needs a starter if it's gonna ferment clean.

Did you do a starch conversion test when you made this?

From what I have read, neither the amber nor the brown malt have any enzymes, so you are going to rely on the Marris Otter for all conversion potential. 1lb of Marris Otter can convert itself plus only 3 or 4 oz of another grain. 8 lbs of MO will only be able to convert 1.5 lbs or so of the other two malts.

No, but i did hit my OG smack on for my standard 72% efficiency.
