Build Your Own BSD Beer Brewing Control System 222
gnuguru writes "Here's a great use for some of your old hardware, a BSD beer brewing kit! Components: one 486, FreeBSD, a temperature logger kit, a relay board, some odds and ends from the useful box, and some time. Summer's just around the corner, so get to work gang!" You'll have to use this recipe, naturally.

By controlling the temperature profile during fermentation it is possible to radically change the "taste" of the product. That is why the Australian / South African wine growers can churn out a reasonably good product cheaply (as opposed to the French) as they use large temperature controlled stainless steel vats with scorched oak chips rather than small wooden casks.

Works fine for me, but only during warm temps, since it only turns the fridge off/on, and doesn't control a heat source.
And as for "open source" beer, there are recipes aplenty freely available on the 'net (e.g., HBD [hbd.org]). All you need is a couple buckets with spigots, an airlock, a kettle, some malt, and some yeast. Far less difficult, and much more rewarding, than open source s/w!

Maybe it takes a lot of energy to brew a lager, but not an ale. I like ales better anyway...

For your information, in France as elsewhere, the fermentation phase of wine brewing is done in large containers (inox or wood or cement vats).
The wine is only transferred to casks when the fermentation is done.
The period while the wine stays in casks is called elevage (can't remember the english term), and aims at refining the wine taste before bottling (this can last up to a few years). Not all wines go through a cask elevage.
There are a few cases of fermentation in casks, but they are truely the exception.
