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 “the Angel’s Share,” what’s left behind after we’re done is truly worthy of envy.
