If it doesn't say straight whiskey, in America that could mean it's 80% vodka, 20% whiskey, aged in used oak barrels, with added flavorings.
Straight whiskey means it's 100% straight whiskey, even if it's a blend of other straight whiskeys (but they must come from the same state), and that it's aged at least 2 years in new oak barrels, with no flavorings or additives.
Straight bourbon means the same, except it's made from at least 51% corn, and if it's aged less than 4 years, it must have a label telling you it's age.
