Even bearing in mind this is a PR exercise for the brewery, it's still a fascinating insight into a plant that produces an average of 1.3 million bottles, 1 million cans, and 2,000 beer kegs daily. The bubbly guides walk you through the factory, filling your head with production ingredients, stages, and numbers. The bottling and canning process is the most interesting, for kids and adults alike. The tour takes 2 hours, including a quiz, but you can squeeze out of the Q&A and head straight to the pub to fill up on complimentary beer. Call a day ahead to book the tour.
