This was flippin' marvellous! I've never done a brewery tour before so I have no basis for comparison, but I had a really good time, Bradley and Gareth who run the brewery are passionate, excited and you can tell they're pretty chuffed that their garage hobby has gone professional. They were very honest and open with any questions asked, and they also offered to sell me malt directly to save me cash.
Also it was great to see that the way we all brew all grain beer is exactly how the professionals do it, albeit with much larger barrels and much more accurate temperature controls than I personally have. They still have their 3 barrel setup in the brewery which they use to run test brews and try out new recipes.
The price was £5 a head, which also gave you two pints in the mezzanine bar. The bar remained open afterwards to purchase beers at a very reasonable price, and take home bottles were also on offer. Minimum 10 people per tour, maximum 25.
If local guys on here are interested I can likely send them a message and organise another one.
