My 'system' has no pumps, no false bottoms, no flashing lights and gizmos, but the beer doesn't seem to suffer from such technical rusticity. Perhaps my favourite piece of kit though is my lagering tank.
If you have followed Fuggled for a while, you know that most of my homebrew projects are done on a small scale, about 2.5 gallons usually, and so a 2.5 gallon water bottle makes an ideal lager tank, once you rack the beer off the yeast cake. You will also know that lagers are generally spekaign my favourite types of beer.
My latest homebrew project to use the lagering tank is a doppelbock, with a starting gravity of 18.5° Plato, which attenuated sufficiently to give me 7.6% abv. I transferred it last night into my latest lagering tank, where it will sit for about 8 weeks, for no other reason than capricious whimsy. I usually give lagering tanks a couple of uses and then chuck them in the bin. An added bonus is that they slip nicely into the fridge, so there is no need to go out and buy a lagering fridge and the attendent temperature controls.
Ever since my first homebrew efforts in a poky flat in the heart of Prague, I have tended to repurpose everyday bits and bobs for the noble art of making beer, you could call me a Homebrew Womble if you wish.
