During our tour of Georgia, our guide took us to a tour and tasting of the Sarajishvili Brandy Factory, about 20 minutes from old town Tbilisi. The grounds are extensive, and you can certainly spend time wandering there on a nice day.
The factory tour was led by a very passionate woman who loved talking about brandy and the brandy distilling process. It was interesting, but about 10 minutes too long, in my opinion.
When it came time for the tasting, we were presented with an enormous assortment of Georgian nuts, cheeses, and fruits to snack on while sampling about 5 brandies. Quite a nice way to spend an afternoon!
