(re-post, got no feedback last time)
2nd all-grain brewed Sunday. This is the first time I'm taking brewhouse efficiency into account. I think I'm doing this right, but my result seems wrong.
Ingredient............Amount % When
US 2-Row Malt......6.00 lb 64.9 % In Mash/Steeped
US Carapils Malt....1.00 lb 10.8 % In Mash/Steeped
UK Light Crystal.....0.50 lb 5.4 % In Mash/Steeped
UK Rolled Oats.......0.50 lb 5.4 % In Mash/Steeped
US Chocolate Malt...0.25 lb 2.7 % In Mash/Steeped
Sugar - Honey........1.00 lb 10.8 % End Of Boil
5.75 gallon in the fermenter when I took the gravity reading (@ 60 degrees F) and I got an OG of 1.058. According to Beer Alchemy, at a 75% efficiency I should have only had a 1.045. I changed the efficiency slowly (80%, then 85%, then 90%, etc.) to see at what efficiency I was running at to get such a high OG until I got the gravity to say 1.058. But I was only able to raise it to 1.058 when my efficiency was at 99%. The FG was measured today and it's at 1.010.
Hydrometer is working & calibrated, I know for sure I had no layering.
Now I highly doubt my efficiency is this high. What could I be missing?
