So what's this whole "beer with twigs" business?
What m'colleague Una alludes to here is a variety of beer - generally referred to as 'real ale' - which is traditionally-brewed, matured in the cask, unfiltered, with what you might call a "rustic" quality to it. Unlike most commercially-made, mass-produced beers, it's not processed for longer shelf-life, doesn't have artificial additives in it, and so on. And the oft-repeated joke is, you can tell it's real ale when you drink it, because it still has bits of twig (from the hops) floating in it. Here in the UK we have the Campaign for Real Ale (CAMRA), a whole organization dedicated to the preservation of it.
