Sour Ale Watermelon is back, just in time for some warm summer weather. We start with a simple sour base recipe which gives us a light tartness upfront. We then add a generous helping of watermelon during fermentation giving us sweet watermelon notes to finish out this beer. It reminds us of a watermelon chupa chup. The watermelon isn’t overpowering – it’s balanced and extremely refreshing.
