Wines by the glass are dispensed through machines that hold 8 bottles of wine, that are operated through a card system. You buy a card, loads it with however much money you want, insert it in the machine, grab one of the 3 different sized glasses 25ml taster, 125 ml, or 175 ml. The idea is that you can try the taster on a few different wines, then once you have found a wine that you like, go to the bar and buy a bottle. Interesting concept, but I never really trust vending machines..!
I am away for the weekend so sorry if I don't respond to any comments straight away
