When we first brewed Practice What You Preach, we secretly took some of the beer aside and stored it away for ageing in freshly emptied Scottish Whisky casks. Now clocking in at 11% ABV, this Quaduple boasts all the characteristics of the classic Trappist-style with swathes of rich whisky after 9 months in La Trappe's cellar. This is a one-off beer we've brewed to share with friends.
