Dextrose corn sugar is an option for those who want to boost the corn-based fermentation in their wash without having to deal with the sticky, gluey mess of an all-grain corn mash. Each pound of dextrose corn sugar added will increase the a.b.v. of a 5-gallon wash by about 1%. Use this corn sugar dextrose to make an easy mash corn whiskey base for this homemade whiskey recipe.
Adding a small amount of dextrose corn sugar (no more than 10% of total fermentation) will increase alcohol content with minimal impact on taste. However, a larger amount of the dextrose enzyme can be added as well for some spirit types (like Bourbon, which legally has to be over 51% corn-based). It should be noted that using dextrose sugar is significantly easier than using corn grain, but will not yield quite as much flavor.
