Rahr Old World Pilsner is special because it doesn’t germinate as quickly as other domestic two-rows which means that more of the insoluble protein is left in the kernel. In this, the malt is giving up some extract but delivers greater flavor, yeast nutrients, and some beer foam stability in return. Also, this malt is lower in DP which means that when step-mashing some starch will convert in the higher temperature range.
