Description
Cask strength spirits are bottled straight from the barrel at natural proof, without dilution or chill filtration. Flask has sourced these high proof releases since 1962, verifying barrel numbers, fill dates, and lab analyses to confirm authenticity. This lineup spans barrel proof bourbon, single cask Scotch, extra añejo tequila drawn directly from oak, and small batch Cognac brandies aged in charred or refill casks. Expect full grain character, concentrated esters, and unfiltered texture in every bottle.
