Difference between straight,small batch,etc

[New2Whiskey]

What is the difference between labels of:

...straight bourbon

...small batch

...single barrell

[cowdery]

Small batch is a marketing term, coined by Beam, and defined very vaguely. Basically, it means the aged whiskey is selected and bottled in small batches, although even there some say small is 25 barrels, while others say 200 barrels is still small.

Single barrel means what the name implies. All of the whiskey in the bottle came from one barrel. So, in effect, it's the smallest small batch possible: one barrel.

Straight has a legal meaning and you might as well read it in the regs, attached.
