Beer and the environment may seem unlikely bedfellows. But when you consider the amount of water brewers use and the risk that climate change might increase the price of your pint, it's clear why the relationship between the two's important.
That's why this week SABMiller, the beer giant behind Peroni and Grolsch, joins us to answer your green questions. It's online until 5pm Friday for You ask, they answer, so post yours below.
Want to know how much water it uses - and what it's doing about it? Interested in the carbon footprint of a pint of beer? Whatever you want to ask about SABMiller and the environment, this is your chance.
Note that anything not about beer and the environment - responsible drinking, for example - will be marked off-topic.
