The nose is rich and decadent starting with dusty oak and butterscotch pudding underscored with bananas foster, coconut macaroons, and fresh cut pineapple then freshly lit pipe tobacco followed by cherry pie filling, chocolate orange and mango that transitions to mild baking spices of cloves, nutmeg, cinnamon, leather and old polished mahogany with medium ethanol burn. The taste is a velvety rich mouthfeel starting with dusty oak and butterscotch pudding that quickly veers towards sweet yet mildly sour fruits of grilled pineapple, toasted coconut, mildly charred lime and slightly underripe bananas then Black Forest gateau, espresso, leather and old polished mahogany with medium ethanol burn. The finish is long starting sweet with boozy pineapple upside down cake with bourbon spiked frosting followed by mild espresso, toasted coconut flakes then mildly sour citrus of cherries jubilee, caramelized mangoes that transitions to mild spices of ginger, leather, and old polished mahogany that lingers for minutes. This is a hell of a rum that those 17 years in ex-bourbon casks have really brought old dusty oak notes that never veer into an overly tannic bitterness but work in harmony with the sweet tropical fruits of the rum as well as rich sweets from the bourbon influence. Foursquare almost always seems to impress me with their creations but these older fully matured in ex-bourbon cask rums are on another level that could compete with spirits that can cost multiples of what a bottle of their rums cost. Unfortunately it seems I missed this release but a huge thanks to @soonershrink for the generous sample for me to try.
