This will depend on whether the charge for entry is truly an “admission” charge as opposed to being a charge for the sale of the wine. If you are allowed entry to the venue without payment of any charge, and the only payment collected is from those who participate in the tastings, then the charge will be considered to be a sale of an alcoholic beverage and the 9% sales and use tax will apply. On the other hand, if everyone has to pay the admission in order to gain entry into the venue, regardless of whether they participate in the tastings or not, then the sales and use tax does not apply to the sale of admission tickets. However, depending on the jurisdiction, the gross receipts from the sale of the tickets may be subject to the admissions and amusements tax. In this case, the entities that are providing the wine tastings are considered to be the consumer of the products, and must pay the 9% tax on the cost of the wine.
