The shop claims to have around 1,000 wines from around the world, 80 of which are available for sampling at any time. They manage this through their special vending machines in store which serve small tasting samples so you can check you like a wine before you buy it. Prices for a sample start at less than 50p.
To try the wines you must first register for a smart card and charge it up with a minimum of £10 tasting credit. Then you can get tasting. By simply pushing the button for the wine you want.
There are separate white wine and red wine machines which are changed every 2 - 3 weeks to keep the selection fresh.
The Sampler is a short walk from Highbury and Islington or Angel tube stations.
