In the survey of almost 2,000 adults, 34% who drank alcohol said they preferred wine to other drinks, against 27% for beer and 20% for spirits.
Some 54% of the population drink white wine and 47% red, with rosé being appreciated by 35% of those questioned.
Wine’s suitability with food was cited by 89% as a reason for drinking, with taste on 77%.
But beer beat wine for outdoor occasions, being chosen by 75% of those surveyed.
Brian Howard, Wine Intelligence’s business development director, said: “This survey provides the most up-to-date and possibly the most comprehensive picture for who drinks what across alcohol categories in the UK.
“One thing is clear: wine is a strong and stable fixture in UK adult social life.”
WSTA chief executive Jeremy Beadles added: “This confirms the strength of the British love affair with wine.”
