In states where it is currently hard to get a license to sell spirits, the stores that currently have those licenses would lose.

In some states the industry of state government loses because distilled beverages are sold only through state owned stores. I live in VA and in 2018 sales at state ABC stores were $1 billion dollars. This generated $196.7 million dollars in net profit. In addition the state generated another $302 million in taxes on sales at these stores.

VA has quite a few distilleries you can visit. You can purchase bottles at these distilleries but the distillery is acting as an agent for the state. Bottles are sold at the same price state stores sell them at, the distillery deposits all sales in a state bank account each night and the distillery is later paid by the state their negotiated wholesale price.

Liquor store owners. In NJ, politicians bribed by restaurants are blocking breweries from serving food.

In NY at least small and medium liquor stores would disappear quickly if their legal mandate disappeared. There's usually one right next to every supermarket, who would love to sell wine.
