Bruichladdich The Classic Laddie is the Islay distillery's flagship single malt. It is unpeated and made from 100% Scottish barley with some barley sourced from Islay. As for the exact recipe of the whisky, this changes from batch to batch with the brand using different barley types from various Scottish farms. Furthermore, various barrel types are used to mature the whisky and this too will vary with each batch with ex-sherry, ex-bourbon, and ex-wine casks among them. That said, since 2016 the brand has a recipe code on each bottle. You can view their website to have your recipe revealed.
