Not many people know this but peanut butter was originally patented in 1884, right around the time the 'Siege of Khartoum' was taking place. We suppose you're not really bothered about either of those facts and all you want to do is indulge in this rich and creamy porter. Dark malts combined with a healthy dose of lactose & natural peanut butter and banana flavourings will ensure you take siege of your senses.
