Sub-Base Malt Gladfield’s Sour Grapes Malt is designed to be used to adjust pH in
the brew house mash. Sour Grapes 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. Use: Use to lower mash pH.
