Before you use it
Every gram of alkalinity comes with sodium attached, so heavy doses salt the beer before they fix the pH. Reserve it for dark beers on soft water and keep total sodium under about 150 ppm.
Description
The reliable way to raise mash pH when a dark, acidic grist drives it too low. Dissolves readily and acts immediately, unlike chalk.
