Fat Rat
Fat Rat is the strong dessert stout of the Rat line, part of the range since its launch in March 2025. The grist is fixed: extra pale malt, oats, chocolate and crystal malt, roasted barley and dextrin malt. It gives a dense, sweet, full body with dark chocolate, cocoa, caramel and a mild coffee roast, and a warming finish with little bitterness. The brewery changes the theme with each edition, borrowing from cakes and confectionery, so nutty, fruity or candied notes come and go while the rich, pudding-like base stays the same.
