Angel's Envy Kentucky Straight Bourbon is finished in port wine casks for an award-winning spirit. We guide each batch's conditioning, blending our handcrafted bourbon in small batches of 8 to 12 barrels at a time. It's typically aged for up to 6 years. While we lose about 5% of the spirit each year to evaporation, or "Angel's Share"�what's left behind after we're done is truly worthy of envy. Once it's deemed ready, we finish our bourbon in ruby port wine casks, which adds subtly distinct flavor nuances that enhance the whiskey without challenging it. Our port finishing process lasts between three to six months, depending on taste. We use 60-gallon ruby port barrels made from French oak and imported directly from Portugal. This creates a whiskey of unprecedented smoothness, sweetness and balance.
