I have done about 5 brews now where the conversion efficiency comes out to around 110%. How is this possible? I have read, and re-read the directions more times than I care to count, and checked and re-checked the numbers I put into brew logs. It says, conversion efficiency is the total strike and sparge water I put into the mash tun measured with the pre-boil volume. Today's brew example: Grain bill: 9.62 lbs Water/Grist ratio: 1.5 qts/lb 14.1 qts strike water plus 19.2 qts sparge water to reach a total of 33.3 qts water pre-boil. This minus losses should give me 28.6 qts pre-boil volume. My pre-boil gravity reading was 1.042 So, conversion efficiency would be 33.3 qts at 1.042 whereas my pre-boil efficiency is 28.6 qts at 1.042. Run the numbers I get 111% conversion eff and 85% pre-boil eff. What am I doing wrong???
