Bottle conditioned only. Previously 8.0%. Some of the oak casks at Samuel Smith's date back more than a century with the individual oak staves being replaced by the Old Brewery coopers over the years. Gradually the casks soak in more & more of the character of the ale fermented in stone Yorkshire squares. Yorkshire Stingo is aged for at least a year matured in these well-used oak casks in the brewery's underground cellars deriving fruit raisin treacle toffee Christmas pudding and slight oaky flavours before being further naturally conditioned in bottle.
