Microbreweries don't produce large quantities of beer that you can buy in every pub. On the contrary, they make beer with an emphasis on the character, flavour and the quality of beer and the brewing technique.
If you love beer, you shouldn't leave this activity out of your stag. The tour includes an English speaking guide who will show you the brewing process.
Of course, a beer tasting is included as well – you will get 4 beers per person.
