Info

Blackprinz® Malt is produced from hulless barley and functions as a 1:1 replacement to debittered black malt, but with smoother flavor. That's because debittered black malts are made by removing a great deal of the husk, but not all of it. Since husk develops bitter notes during roasting, debittered black malts will contribute a certain amount of bitter, astringent or dry flavors or after taste to beer. 

Blackprinz® Malt will contribute the same color characteristics as Black Malt but without the bitter, astringent, dry flavors or aftertaste.

Use in Black IPAs, Black Lagers, Black Ales, Schwarzbiers and other beers for deep, rich color with only hints of subtle roasted flavor, and for color adjustment in any beer style
