Now, to check your measurements for accuracy, you can use gravity points on the cold volumes and it should be roughly equal between pre-boil and post-boil numbers. Your pre-boil volume of 10.45 gal (hot) ended up as 5.95 gal (cold) in the fermentor and 0.25 gal (hot) of loss to trub and chilling. You can change this in your BeerSmith settings under 'options' > 'advanced' > 'grain absorption' Your grain charge was 22.25 lbs, so your water absorbed by the grain was: You added 12.8 gallons of water (assumed cold) and collected 10.45 gallons pre-boil (at sparge temperature). That is the volume measurements were recorded at near boil or sparge temperatures. For the following calculations, I am assuming that the measurements were taken at temperature. You know you get 70% mash efficiency and you have 0.5 gallons of trub left in the kettle. Use this in your equipment profile as BHE. Once you've brewed and measured gravity & volume along the way, you'll find the Measured Efficiency field in the Fermentation tab. The thing to do is to just subtract your trub percentage by the percentage of wort volume in the fermenter to get into the ballpark. Without increasing ingredients, the ONLY place this sugar can come from is higher mash efficiency, which is exactly what BeerSmith does. As soon as you add trub loss, you need additional sugar to cover the additional volume. With Loss to Trub set to zero, it is the same as Mash efficiency. If you input 75% BHE, then your saying that no matter what, you can get 75% of the available sugars into the fermenter. BeerSmith calculates gravity based on this number. If you notice in the Equipment profile, it doesn't even ask your kettle size, so in essence, it's telling you how big of a pot you need.īrewhouse Efficiency is what gets everybody. If you know your kettle will only hold 7.5 gallons, and you want to boil longer, then the batch size must be reduced so that it doesn't overflow. If you say you want 5.5 gallons, then all water amounts will adjust to yield that. This is the total percentage of all available sugars you want in the fermenter. This is the amount you want in the fermenter.Ģ) Brewhouse Efficiency. With BeerSmith, you set two parameters that everything else adjusts to create.ġ) Your batch size.
