Editing grain absorption in beersmith 34/22/2024 ![]() ![]() ![]() Here is an example of scaling a recipe from a four gallon batch to a five gallon batch. The same formula can be used to adjust a recipe for lower/higher AA% hops in the same size batch. If a 5 gallon recipe calls for 1 oz of 5% AA hops and you want to brew 10 gallons with a 4% AA hop the formula would be: (1 oz * 5% AA * 10/5)/4% AA = 2.5 oz of 4% AA hops. ![]() To do this take the weight of each hop addition in the recipe and multiply it by the percent alpha acids called for and the ratio of the batch sizes, then divide by the percent of alpha acids in the hops you are using. For example: if the recipe is designed to produce 5 gallons of wort and you want to brew 10, multiply the weight of each of the malts (adjuncts, sugars, spices, fruit) by 10/5 = 2.įor the hop additions rather than doubling the weight of each addition double the amount of alpha acids contributed by each addition. To convert a recipe to a different volume multiply each of the ingredient (hops, malt, sugars, spices, fruit etc.) by the size of your batch divided by the size of the recipe. Fairly frequently I hear someone complain that they accidentally doubled the hops (for example) and didn't realize until it was too late (and the wort was in the fermenter). However, I think it's important to develop some instincts on how recipe adjustment works. Many of these calculations are easy to do with a copy of BeerSmith, ProMash, BeerAlchemy, or one of the dozens of other programs/websites/spreadsheets designed to do recipe calculations. Whether you want to brew a batch that is a different volume, your efficiency is different than the recipe, or you brew with extract, this guide will show you how to adjust the recipes to suit your system. I post the recipes as they were brewed with the actual volume and efficiency rather than converting them to a consistent format, and I realize that this can be a hassle. With nearly 100 homebrew recipes posted on The Mad Fermentationist over the last four years it was time to post a guide on how to adjust them for different setups.
