Spent Grains from Beer Brewing
Spent grains are the residual barley husks and other solids left after mashing in the beer brewing process. This byproduct is classified under HTS 2303.30.00.00 as brewing dregs and waste, often dried or pelleted for use as animal feed. It provides a high-fiber, protein-rich supplement primarily for livestock.
Distillers Dried Grains with Solubles (DDGS)
DDGS is a byproduct of ethanol or distilled spirit production from fermented grains like corn, consisting of dried grain residues and solubles. It qualifies under HTS 2303.30.00.00 as distilling waste, commonly imported as a cost-effective protein source for ruminant animal feed. The material retains nutritional value post-fermentation.
Brewery Draff Pellets
Brewery draff refers to wet spent grains from malt mashing in beer production, often pelleted for easier transport and storage. Classified as brewing waste under HTS 2303.30.00.00, these pellets serve as a fiber-rich feed for cattle and poultry. They are a sustainable byproduct of the craft beer industry.
Whiskey Distillers Grains
Grains remaining after whiskey distillation from fermented barley or other cereals, typically dried for export. This distilling waste under HTS 2303.30.00.00 is valued for its digestible protein in dairy cow rations. It's a key export from Scotch and Irish whiskey producers.
Pot Ale Dried Solids
Pot ale is the liquid residue after initial distillation in malt spirit production, evaporated and dried into solids. Classified under HTS 2303.30.00.00 as distilling waste, it's a soluble protein source for pig and poultry feeds. Common from Scottish whisky distilleries.
Craft Beer Spent Hops
Spent hops are the exhausted hop cones after extraction in beer brewing kettles. This brewing waste under HTS 2303.30.00.00 is sometimes pelleted for niche fiber feeds or soil amendment. It retains trace bitterness compounds useful in ruminant diets.
