This special Reserve Grappa is matured in oak casks for a long period then is refined in American (Tennessee) barrels for some months. These barrels had been previously used to mature a \'Tennessee Whiskey\' of one of the most prestigious distilleries. This particularly innovative method experimented on grappa by Sibona Distillery has proven to be exceptional as regards to quality results. Grappa\'s intense bouquet with malted notes and complex flavour with persistent aftertaste recalls those of Tennessee Whiskey.
