Frederick you can do some close wineries, and there is a cidery (sp?) close too, as well as some breweries in Fredrick where you can tour, but the weekend tours book up fast. The downtown shopping/restaurant area is cute too. DInner at Volt is probably booked, but maybe you could get a brunch seating. My recollection is that there is a bit less in Middleburg as the main street is quite small, but that there are more nearby wineries.
