Wine brings pleasure. But for some it can also prove painful. Red wine is particularly problematic for a proportion of the population, with just a few mouthfuls bringing on swift and excruciating headaches.

Now scientists think they may finally be on to why. In lab experiments, they've identified a compound in red wine that impedes the breakdown of alcohol by the liver and causes a build-up of toxic acetaldehyde in the bloodstream. Human trials are still needed for confirmation - but these are exciting findings.

In this episode, we discuss these results with the scientists behind them: Professor Andrew Waterhouse and Dr Apramita Devi from the University of California, Davis.

As for the BIG question - which red wines might be safer for sufferers - there's good news. The experts actually recommend cheap rather than pricey red wines. Yes, you read that right: the boffins are endorsing the bargains! We explain why as well as providing some top tips for bargain basement reds - we also touch on the tantalising prospect of how this research may help us understand hangovers too.

A final note: research like this costs money and yet neither governments nor big companies want to fund it (a crying shame). As a result, the team at UC Davis has launched a Crowdfunder. If you'd like to contribute, or find out more, click here: Red Wine Headaches Project
