Generally speaking, standard vodka is significantly stronger than the average liqueur. Commercial vodka is typically bottled at an alcohol-by-volume (ABV) of 40% (80 proof), whereas most traditional liqueurs feature a lower alcohol content ranging between 15% and 30% ABV due to added sugars, flavor extracts, and fruit juices. However, certain specialty high-proof herbal or botanical liqueurs can match or exceed standard spirit proofs.
