## Notes

The grain bill calculations are based upon the formula of Holle (2010), formula 1 (p. 4). The coarse-grind, dry basis (CG db) values are typically from the malt analysis information.

Sugars are calculated at 100% efficiency. The sugar yield is expressed as a percentage of sucrose (100%). For example, one pound of honey (1.032) provides less sugar than one pound of sucrose (1.046). Thus, the sugar contribution of honey compared to sucrose is (32/46)*100 = 69.6%. Similarly, liquid malt extracts have a yield of about 76%.

Grain color units are referred to as Lovibond in some sources and SRM in others.
