We generally expect a glass of wine to be perfectly clear and crystal clear. Some people may therefore be a little surprised to find grainy or powdery residues when pouring the last glass from a bottle or looking at the bottom of it. Where does this deposit come from? Can it alter the taste of the wine or have adverse effects on the consumer's health?

We explore this topic in this episode of EXTRA BRUT, our educational web series about wine, with food and wine critic Nicolas Rieffel. The goal: to answer in record time all the questions you've ever asked yourself about wine...
