You are confusing duty free limits with liquid restrictions. 2L of booze is fine, or even more, so long as one declares it upon arrival. The restrictions on booze in the hold relate to highly flammable proofs, that's it. Accordingly, you could fly with 150 proof in the hand baggage, but nothing more than 140 proof in the hold.
