There's no formula for the perfect time to age your spirits. Age to taste! We suggest you taste your spirits every week and once aged to YOUR taste, start drinking or move it to a glass bottle to stop the aging process.
Yes... due to the greater surface or contact area ratio, small size barrels will age 5 to 10 times faster then your standard 55 gallon barrel. These means that one month in a small barrel will produce the equivalent aging to 1 to 1 1/2 years in a full size barrel.
When alcohol is distilled, either from potatoes, corn, fruit, grain or sugar cane, it produces Ethanol. A clear and tasteless alcohol. Distilleries then flavor and filter the alcohol to get their unique flavor. Vodka is the only alcohol you can buy in an unflavored form. When mixed with a bottle of Swish Barrel Premium Essence, you can recreate the taste of many of the famous brands or create your own flavor.
