Have visited Tring Brewery both on a tour and simply to the shop.
The venue is located just off the main London Road opposite a large Tesco and is in the grounds of a farm.
The shop is at the front as you enter and the brewery itself to the rear.
The shop stocks a fair range of Tring bottled beers and also has 3 cask engines dispensing Tring beers for take away in 2 litre PET bottles. A great vfm option for a BBQ/party. They also sell local produce such as chutneys, jams etc as well as brewery merchandise.
The place has a good feel about it, wooden floor, a proper bar area where the cask engines are located and a few seats/benches inside.
I did the tour in late 2010 on a Friday night - approx 20 people.
This was excellent vfm - around £15 including a fish supper and as much beer from the bar as you could handle in 2 hours!
Good little venue and well worth doing the tour just for a decent little session if nothing else!
