Crisp Rice Hulls are an all-grain brewing aid that keeps sticky mashes flowing. A by-product of the rice industry, the inert, fibrous hulls form a filter bed in the mash tun, which helps when your grain bill is heavy with wheat, rye or oats. This 1kg bag suits regular all-grain brewers.
What they do
- Form an open filter bed in the mash, improving run-off and wort clarity
- Flavourless, with no aroma
- Do not soak up much wort, so your yield is kept
How much to use
Crisp recommends 1-5% of the grist weight, depending on how much wheat, rye or oats is in the recipe. Mix the hulls evenly through the grain so the whole bed drains well.
As a guide, 1-5% of a 5kg grain bill is 50-250g, so a 1kg bag covers several brews.
Useful with
- Wheat Malt - for wheat beers, where a stuck mash is common
- Rye Malt - rye is notoriously sticky
- Flaked Oats - for smooth oatmeal stouts and hazy pales
Ideal for anyone brewing on a Grainfather or other all-grain system. Also available in 500g and 250g bags.
