Plumper kernels usually provide a better yield. At least 90% of kernels should be of adjacent sizes to ensure an even crush in your mill.

Often listed as "Fine Grind, Dry Basis" (FGDB). It tells you the maximum amount of soluble material you can get from the grain. Higher extract values lead to better profitability and yield. buy malt

These features help you predict your "brewhouse efficiency" and the physical behavior of the mash. Plumper kernels usually provide a better yield

These features tell you how easily the grain's starches will convert into fermentable sugars. It tells you the maximum amount of soluble

A precursor to Dimethyl Sulfide (DMS), which smells like cooked corn. Pilsner malts often have high SMM and require a vigorous boil to drive it off. Buying Guide Summary Feature Category What to Look For Why It Matters Extraction FGDB > 80% Higher yield of alcohol per pound Crushability Friability > 80% Ensures effective milling without "gumming" Yeast Health Sufficient FAN levels Prevents "stuck" or smelly fermentations Beer Clarity Low Beta-Glucans Prevents hazy beer and slow filtering

Measures the enzymatic activity (Lintner). High DP malts (like North American 6-row) are essential if you are using a lot of un-malted adjuncts like corn or rice.

Represents the ratio of soluble protein to total protein. It tells you how well the malt was "modified" during germination; a higher KI typically means more of the starch is accessible. 2. Physical & Yield Metrics
