The idea of the self-serve tasting bar is a pretty good one, even if the tastes can cost $5, $10, $50 or more. The machines have been popping up for a while.

Anecdotal: Knew a man who built a restaurant around the theme of tasting wonderful wines with these machines. After a couple of years the business has closed and the winecentric part of the business is being removed. Traditional restaurant pays the bills a bit better. Cannot image where the concept is working if it cannot work in this high-end wine consuming community. The machines were cool and the wine tasting was an educational experience, though a bit pricey.
