On a more somber note, be very cautious of anything resembling the sale of alcohol in the USA. Unlicensed sale of alcohol interferes with revenue collection, and nothing makes a politician crazier than the loss of someone else's money for the politician to spend. I say that tongue-in-cheek, but bootlegging has serious penalties, so it's worth thinking things through first.
My son & niece are part owners of our 2020 and 2021 reds. I keep track of all costs, and they reimburse me for their part of the batches.
I use the word "cost" to emphasize that no one makes any money, or receives anything else for the wine. We are a co-op, and everyone pays their share of the costs, including corks, capsules, and printing labels. All labor is donated.
If you make wine for anyone, emphasize "cost" and avoid "price", as price indicates sales.
While there is little risk in making a few batches of wine, my dad was a cop and he taught me to fly under the radar. Not being noticed avoids unnecessary hassles.
