I've just had some more Cask 21C Malvasia Madeira, it is terribly good. Straight out of the fridge it really shows that it can be a refreshing drink thanks to all of that acidity. I like its slightly off, savoury character too. Oddly, there is some fruit as well. I admit it is candied, preserved fruit, but fruit nonetheless. This is Madeira at its coolest and I love it.
