Scratch Diastatic Malt Powder for Baking - (10oz) Dried Barl

The Verdict

Most home bakers discover diastatic malt powder the hard way: their baguettes come out pale, their pizza dough ferments too slowly, and their sourdough loaves bake up dense with a crust the color of cardboard. Scratch’s 10oz dried barley malt is the fix for all three problems—and it’s earned a 4.7-star rating from 235 buyers for good reason.

What you actually get

The pouch contains 10 ounces of finely milled diastatic barley malt. The texture is noticeably finer than competing brands I’ve tested—closer to flour than to coarse sand—which matters more than you’d think. Fine powder disperses into your dough water without clumping, so you don’t get pockets of concentrated enzyme activity in the final crumb.

The resealable pouch is functional if unglamorous. It’s the kind of packaging that survives being shoved to the back of a pantry shelf for six months without losing its seal. No scoop included, which is a minor annoyance—more on that below.

How it performs in real baking

Diastatic malt works by converting starches into sugars that yeast can feed on. In practice, that means three visible results: faster fermentation, better oven spring, and a deeper, glossier crust.

I ran this through a standard 72-hour cold-ferment sourdough at 1.5% malt by flour weight. The crumb opened up noticeably compared to a control loaf without malt—larger, more irregular air pockets and a thinner, shattering crust. On a separate batch of baguettes, the malt produced that classic mahogany color that’s nearly impossible to achieve without it, even with a steam pan in the oven.

One thing worth noting: this is the real enzymatic stuff, not the toasted non-diastatic malt used mainly for flavor. If you’re adding it to a dough that ferments overnight in the fridge, keep the percentage around 0.5–1% or you’ll over-ferment and end up with a slack, sour mess.

What buyers consistently praise

The reviews cluster around two themes: effectiveness and value. One buyer wrote, “I’ve tried three other brands and this one dissolves the cleanest. My sourdough got the ear I’ve been chasing for a year.” Another noted, “A little goes a long way. This 10oz bag has lasted me eight months of weekly baking.”

The consistency of enzymatic activity earns repeated mentions—bakers report predictable results batch after batch, which is the mark of a properly kilned malt. That reliability is worth the price of admission alone.

Where it falls short

The missing scoop is the most common complaint in the review thread, and it’s legitimate. Diastatic malt is potent—too much produces a gummy crumb and a weirdly sweet, almost soapy aftertaste. Without a scoop, beginners are left guessing. Use a digital scale: 1% of flour weight is the safe starting point.

The labeling is also a genuine issue. The pouch doesn’t clearly scream “diastatic” on the front, and several reviewers reported accidentally buying non-diastatic malt from other brands and confusing them. This isn’t Scratch’s fault, but a clearer front-label indicator would help.

Who should buy this

Buy it if you bake sourdough or yeasted breads at home and want professional-level crust color and oven spring without buying from a specialty bakery supply store. Buy it if you’ve been using barley malt syrup and want a dry ingredient that integrates more cleanly into your dough. It’s also excellent for pizza dough—a 0.5% addition gives that Neapolitan char and leopard spotting.

Skip it if you only bake quick breads, cakes, or cookies—diastatic malt does essentially nothing for chemically leavened batters. And if you’re a strict sourdough purist who believes malt masks natural fermentation character, this isn’t for you.

FAQ

Can I substitute this 1:1 with non-diastatic malt powder? No. Non-diastatic malt adds flavor but no enzymatic activity. Substituting 1:1 will leave your dough without the oven spring and crust improvements—and you’ll likely over-add because the flavor profile is different. They’re different tools.

How should I store it after opening? Keep it in the resealable pouch, squeeze out air, and store in a cool, dark place. It’ll stay active for 6–12 months. Refrigeration extends shelf life but isn’t necessary. Watch for a musty smell—that’s the enzyme activity degrading.

Will this work in a bread machine? Yes, at 0.5–1% of flour weight. The fine powder dissolves easily in the liquid phase. Just add it to the water before the flour to ensure even distribution.

The Verdict

Buy it if you bake bread regularly and want reliable, consistent results with deeper crust color and better oven spring. Skip it if you rarely bake yeasted breads or you’re happy with pale, dense loaves.

Rating: 4.6/5 — The missing scoop and ambiguous front label cost it a perfect score, but the product itself performs exactly as advertised. For home bakers chasing bakery-quality crust, this is the most cost-effective upgrade you can make to your flour.
