I brewed my first batch in 14 years. I am making my old favorite a Koelsh style ale. There have been many things that have changed in 14 years and something new, at least to me is the availability of all of these online calculators.
I calculated out my recipe and naturally exact weight and volumes could vary but from this site it shows efficiency of 100%. I never measured this before and wonder about its.
Here is my recipe:
8 lbs of Weyermann Pilsner Malt
.5 lbs of CaraFoam Malt
Pre boil volume of 7 gallons
Post boil of 6 gallons
Mashing Technique - Triple Decoction (3 Hour Duration)
Sparge Technique - Hybrid Fly
I was thinking the weight of the grain might be off a bit, but I trusted the stores calculations.
