The idea is that you get 13 bottles of beer each quarter - not enough to keep you going, I know, but the first box certainly provides an interesting addition to the cellar. It's a really thoughtful selection of beers and the ones I've had so far - Burton Bridge's Burton Porter and Eccleshall Brewery's apallingly-named 'Top Totty' (Please, guys. Stop it. Now.) were really great beers.
I may be wrong - I may just have been lucky - but I suspect that there's some quality control happening on beers that are included. There are ones I recognise from Meantime and Breconshire, but most of them are form micros around the country I haven't come across before.
And you get free glasses and bottle openers and stuff too, and some notes about each beer.
Well worth checking out.
