Siren brewed this beer in 2016 with the sole intention of ageing it in bourbon barrels. The inspiration was all about tamarind - an ingredient rvered for the sweet and sour depth it can add to dishes and drinks, particularly popular in the tropics. It didn;t disappoint - offering an amazing fruity aroma almost immediately. In folklore, tamarind trees are said to harbour ghosts, and for that reason are often found on the outskirts of villages. Siren's Sheltered Spirit has serenely matured into something very special.
