Brew designed to survive trips to the subcontinent, in brief

IPA

Think of the bitter, hoppy beer that once preserved itself on long voyages to India.

This clue refers to India Pale Ale, shortened to "IPA," a beer style originally brewed stronger and with more hops to endure long sea voyages to British colonies like India (the "subcontinent"). The "in brief" signals the abbreviation, while "brew designed to survive trips" hints at its historical purpose—preserving the beer during transport. It’s a common crossword shorthand for the drink.
