Working with Extract Recipes
Replace gravity points with an equivalent amount of pale extract – If you want to substitute liquid malt extract (LME) for the base malts, divide the total gravity points contributed by the base malts by 36 to get the pounds of LME (or liquid sugars) required. If substituting with dry malt extract (DME), divide the total gravity points contributed by the base malts by 45 to get the pounds of DME (or dry sugars) required. If you want to use both LME and DME, keep in mind that the total gravity points contributed by malt extract should match what was contributed by the base malts in the original recipe.
