Texas distillers can sell only a limited amount of their product on premises.
“Texas spirits (not beer or wine) have a 3 tiered system which means a distiller must sell bottles to a distributor who then sells to a liquor store. A restaurant/bar purchases their alcohol from a wholesaler/liquor store.
“Texas distillers are currently limited to 3500 gallons per year to sell in bottles direct to customers.”

So it’s possible that they’re not a 51% establishment.
