The Telltale Sign The Bourbon You're About To Drink Will Go Down Smoothly - Tasting Table
Briefly

A lower ABV bourbon provides a smoother drinking experience as it has less ethanol content, which means less burn when drinking it. However, smoothness is also influenced by sweetness.
High-proof bourbons can be smooth if they have a higher sugar content due to more caramelization from barrel aging or a higher percentage of corn, which naturally adds sweetness.
The color of bourbon can indicate its smoothness; generally, the deeper the golden hue, the smoother the taste due to the extraction of flavor and color from the barrels.
