Do they regularly sell wine in their stores? Do they regularly have alcohol being consumed in their stores?
Do they charge a fee for a "wine tasting" or do they merely give it away as is customary with a "wine tasting"?
Reading the law as you quoted above, the little word AND is more than a mere conjunctive. It says both elements must be present for the misdemeanor to exist. The alcohol must be both sold AND consumed. If the wine tasting was free, the fact that consumers might partake is irrelevant if they did not purchase the product. If the store sells alcoholic beverages but does not have consumption on premesis (apart from free wine tasting) that would not likely apply either.
The law in question would seem to indicate that you shouldn't visit a bar or tavern while carrying. It would appear also to rule out restaurants where spirits are sold and consumed, such as Applebees or other places of that ilk.
It seems extremely unlikely that the law would apply to a supermarket, hardware store, or any other location where sample products might be consumed but not sold, or sold but not consumed on premesis.
Then again, I ain't an attorney so you might check with one. But I do have the ability to read, and the law appears to be quite clear in the wording as applies to your question.
