Indiana looks to make a name for itself with 'Indiana Rye Whiskey' by Margaret Menge, The Center Square | March 03, 2021 09:30 AM Print this article Indiana isn’t known for whiskey, but it could be in the future. A state representative from southern Indiana introduced a bill in January to brand “Indiana rye whiskey” and define it as a whiskey made in Indiana from a mash containing at least 51% rye, distilled to no more than 80% alcohol by volume (160 proof) and aged in new, charred white oak barrels for two years. Rep. Chris May, R-Bedford, says he introduced the bill to establish standards for Indiana rye whiskey and boost the growing number of distillers and the growing popularity of rye whiskey.
