Wine is extremely popular with adults all over the world, so it makes sense that the taste would be capitalized on in other ways.
Wine biscuits are an Italian specialty that are favorited in Rhode Island and surrounding areas. They are an exotic hybrid of savory and sweet. Made with red wine, oil (typically olive), sugar, and a bunch of flour, they can end up with a super subtle purple-ish hue, and they’re often twisted into a little ring.
A basic recipe to make 30 wine biscuits requires a cup of red wine, so wine biscuit bakers have to stock up on bottles and bottles of wine at regular liquor stores, with none of the discount from buying a product in serious bulk.
As wine biscuits become more popular outside of Rhode Island, it is expected that more bakeries may decide to produce them for their wine-loving customers.
