Tried the Brewsmith trial, but couldn't really work out what it was telling me as total liquor was around 40 litres Note that there will be some fermenter losses so this final keg or bottle volume will differ.Thanks, its only the first brew and first non kit experience, so early days, just trying to work out how I get bigger FV quantity, I have 30l kegs to fill so 27 litres in the FV would be a good target. Batch Volume = final volume in the fermenter after chilling and transferring.Evaporation Rate = 3L/h for 230V, 2L/h for 120V (evaporation rate is lower for 120V GF models as it has 1600W heating element rather than 2000W).This will depend on the boil time and evaporation rate) Boil Off Volume = Evaporation Rate x (Boil Min/60) (water volume lost to evaporation during the boil.Will change depending on the amount of kettle hops and determination of brewer to maximise fermenter volume.) Includes both chiller losses and trub loss in the boiler. Post Boil Losses = 2L (rough estimate.Grain Absorption Ratio = 0.8 (ratio to determine the amount of water that is absorbed in grain which will be removed after sparging).Grain Weight = total grain weight of all the grains included in the mash – exclude late sugar additions weight.Mash Tun Deadspace = 3.5L (dead space between the base and bottom of grain basket).Optimum value for mashing in G30 from testing) Water To Grain Ratio = 2.7 (litres of water per kilogram of grain.What those terms mean (example G30 Brewing unit): Pre Boil Volume = Batch Volume + Post Boil Losses + Boil Off Volume.Sparge Volume = Preboil Volume – Mash Volume + (Grain Weight x Grain Absorption Ratio).Mash Volume = (Water To Grain Ratio x GrainWeight) + Mash Tun Deadspace.The Calculations used in the Recipe Creator on the app are as follows:
