If a bottle of wine disappears rather quickly after you open it, your genes may be partly to blame.
The amount of wine someone gets through in a week is significantly influenced by their genes, a study suggests.
This could add as many as three drinks to someone's average weekly consumption.
Researchers looked at genetic analysis for almost 3.4 million people, mostly from a white European background, including people in the UK, who were asked how many alcoholic drinks they consumed in an average week.

For those from a European background, the 10 per cent of people with the highest genetic score linked to drinking put away more than seven drinks a week on average.
The 10 per cent of people with the lowest genetic score drank less than four drinks a week on average.
Professor Dajiang Liu, a co-author of the study, from Penn State University, said: 'How much you drink may not be entirely down to whether you had a stressful day, or how good the bottle of wine in the fridge tastes - genes play an important partial role.
'These findings could also help to explain why there are some people who are always available to go to a bar for a drink, or willing to open a bottle of wine.
'However we can't entirely blame our genes, as behaviour is very important in drinking behaviours, and it is always possible for people to decide to cut down on alcohol and lead a healthier life.'
People have around 20,000 genes - the 'blueprint' for everything from eye colour to intelligence and behaviour - in almost every cell in their body.
