Adding Maltodextrin to your extract brew will help you fine-tune the body and mouthfeel without affecting the flavor. The Maltodextrin molecule is a chain of sugars between 4 and 20 dextrose units in length. That means it is only 3% fermentable by brewer's yeast, and so will contribute body to the finished beer. It is naturally present in all finished beers, up to 6% by weight, but the grains that yield it in All Grain brews don’t respond well to steeping in extract batches.
Our maltodextrin is composed of .5% dextrose, 2.5% Maltose, 3.5% maltotriose, 93.5% higher saccharides, and is made from corn. It is often also referred to as Dextrin or Dextrine Powder.
