What is the term for a group of three or more glasses of bourbon presented for comparison?

The term for a group of three or more glasses of bourbon presented for comparison is known as a flight. This practice allows enthusiasts to sample and compare different bourbons side by side, making it easier to identify distinct flavor profiles, aromas, and other characteristics that might differ between the selections. A flight is designed to enhance the tasting experience, providing both educational value and enjoyment as participants explore the subtleties of each bourbon.

The other terms do not quite capture the specific notion of a formalized tasting arrangement. A set could refer to any collection of glasses, but it does not imply the comparative aspect. Tasting, while relevant, generally refers to the act of sampling itself rather than to the organized presentation of multiple samples. Collection usually pertains to a group of bottles or products rather than an organized tasting format. Therefore, "flight" is the precise term used in this context to describe the structured experience of sampling multiple bourbons for comparison.
