## Notes

The grain bill calculations are based upon the formula of Holle (2010), formula 1 (p. 4).

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%.

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