Four of the independent retailerís five branches are being equipped with the machines and have licences allowing the consumption of wine on the premises as part of a sub-brand called Taste.
The branch at Alderley Edge already has two machines fitted, and Chester is on course to have six machines installed by mid-September.
Customers can sample any number of wines, using the swipe card system. They can also buy larger sample measures to share as well as 12.5cl and 17.5cl glasses to consume in a seating area.
In addition, they can purchase a bottle of the wine from the shelf and consume it on the premises for a corkage charge of £3.50.
Owner Ruth Yates said: ďPeople often get in a wine rut, buying the same bottle of Pinot Grigio or Bordeaux again and again. This way, they can explore new flavours, discover alternatives to their repertoire and find out a little more about whatís in the glass from our knowledgeable team.Ē
