Sour Malt | Acidulated Malt | IREKS Malt

• Contains up to 4.5% natural lactic acid to precisely adjust mash pH, promoting enhanced enzyme activity
• By optimizing mash pH, this acidulated malt directly contributes to a higher brewhouse yield
• Use as up to 5% of your grain bill

IREKS Sour Malt, also known as acidulated malt or saurmaltz, with its natural lactic acid content of up to 4.5% is an excellent solution for precisely adjusting mash pH. Compared to typical sour malts, IREKS contains roughly double the lactic acid, allowing you to use as little as half the amount to achieve the same results. This optimization directly supports enhanced enzyme activity, leading to a higher brewhouse yield.

The ideal addition rate of IREKS Sour Malt will vary for each brewery. Factors such as brewing water quality, mashing schedule, and grist composition all influence the precise amount needed for optimal results.

Comparable to Weyermann Acidulated Malt, but IREKS Sour Malt has a much higher lactic acid content of up to 4.5% rather than the 1-2% of the Weyermann. IREKS Sour Malt is able to achieve the same pH adjustment with less usage in the overall grain bill.
