We get together once a month at either someone's home for a potluck and a blind wine tasting or occaisionally we will meet at a winery.
We keep the group size at these events relatively small. Usually less than 20. We announce an event by email with a link to a RSVP form. When the event is filled we take no more reservations. It usually takes no more than a day or two for our events to fill up. You have to act fast!
