0k, and the moment, it'sjust a prototype? shouldn't get too excited, should we? we brought this to showcase at cop but also its its first global premier here at the bbc. it will be available for anyone to buy next year. thanks, jonathan. great stuff. now, something to raise a glass to. last orders! 0h, right, in that case i will have a pint of lager, please. we've got two on tap today. one is made from bread, the other one is a local brew made from old scraps. excuse me? i'll explain. right. you try that, this is a zero—waste sour made by drygate brewery across the clyde there. it's a concocted from unwanted fruit and veg that would otherwise end up in landfill. itjust tastes like a fruity sour beer, so fair do's. good, but don't enjoy it too much because it is just part of a campaign that is lasting for a month over cop 26. ok, so not a long—term plan then.
