Molly Rose Tank 5 Blend Spiced Sour Ale with Blackberries Can 375mLSpiced Sour Ale Blend with Blackberries 4. 6% "A blend of 1 year, 2 year and fresh beer. TANK 5 played host to this cracking blend to which we have added left over botanicals from our pastis giving it a vermouth like character that plays beautifully with layers of farmhouse complexity. Our "Not Wasted" series uses waste products from like minded drinks businesses, including ourselves!" Molly Rose
