For Tomatin's Cù Bòcan single malt Scotch whisky, the distillery takes lightly peated single malt and matures it in a combination of Sherry, virgin and bourbon casks. However, for this limited edition release, the lightly peated single malt has been fully matured in virgin oak casks, which aren't used all that often (though it is increasingly becoming quite 'a thing' these days). Just 6,000 bottles of Tomatin Cù Bòcan Virgin Oak were produced - the second release in a series highlighting the individual cask styles that go to make Cù Bòcan.
