* Analyses are offered at a discount to all New York bonded wineries, home winemakers, and craft distilleries because a portion of testing costs (approximately 33%) are subsidized by the New York Wine and Grape Foundation (NYWGF). We are unable to offer this discount to wine distributors or out-of-state wineries because of the nature of NYWGF funding.
