Whiskey Del Bac Classic single malt, 46% abv, desert-made in Arizona. Tasted neat... for the third time. Copper color and very little coating legs in the glass. Apples, stone fruits, hint of caramel and vanilla and a little spice dust on the nose. Big flash of ethanol and baking spices in the mouth. Astringent and tannic, oak char, grain sweetness. Finish shows some sweetness and tingling mint and spices, but also an underlying ethanol burn that leaves me feeling like... heartburn. Tried this three different times to figure out what's going on here, and got really consistent results every time. Tried the Whiskey Del Bac Dorado single malt smoked with mesquite and LOVED it (4.75), and then tried the Classic and Dorado side by side. Really different outcomes. While this Classic is OK, it's not in the same class as the Dorado. Or maybe the Dorado's mesquite smoke just hides the distillate or barreling flaws inherent in the Classic. Disappointed... and left with that heartburn feeling. Ice definitely helps this whiskey--don't let your glass leave the bar without some. Update: I've been drinking down this bottle with ice, and I feel a little better about it over time. It shares a hint of the mesquite smoke that makes the Dorado so good IMHO (even though this is an unsmoked malt mashbill). Maybe it's the barrel or barrel char. And an ice cube solved the heartburn feeling. Be generous and call this a 3.0/5.0, a passing grade 60%.
