Yes, you are always welcome to bring your own food. The only day that we have food available right now, apart from private tastings, is on Saturdays. Lately we've been offering Busbee's Bar-B-Que (from Bandera). You might call ahead to check just to be sure what might be available on the day you're planning your visit.
When I was there last summer they offered a very good cheese and fruit plate.
