Gladfield Sour Grapes Acidulated Malt

Regular price $5.95 $3.95 Sale

Gladfield Sour Grapes Acidulated Malt is designed to be used to adjust pH in the brew house mash. Gladfield Sour Grapes Acidulated Malt is produced by encouraging lactic growth during germination from naturally present bacteria on the grain, and then washing the malt in a lactic bath using the same Lactobacillus strain, before kilning. Reduction of wort-pH leads to a better mash, intensified fermentation, lighter Pilsner colour and improved flavor stability and beer flavour.
