STR Cask Matured or in plain English : Shaved, Toasted and Re-charred Red Wine Casks.
Anthony Wills selected 43 casks filled in 2012 and bottled at 50% abv for this latest barrier pushing project.
The process of shaving, toasting and re-charring has had a huge influence on these casks and the flavours of the resulting single malt. Kilchoman released a full maturation Red Wine Cask release in 2016 which took on lots of the big and bold wine flavours, however the STR cask provides a different approach. The shaving has reduced some of the bolder flavours on the surface of the oak, producing a more subtle red wine influence. Once shaved, the casks were then toasted and charred over a natural oak fire, fuelled exclusively using oak chips from used staves. These processes remove harsh tannins and undelivered flavours and break down unwanted chemical bonds such as lignin, cellulose’s and hemicellulose’s, replacing them with sugars, vanilla and spice notes.
