It was snowing here today, it's fucking cold. I left a bottle of white wine outside and it's the perfect temperature now, breddy good.

If you're not intent on using what you already have, you could buy a water butt. I see these in people's gardens sometimes and they're just used for watering plants and such. Or i guess you could try to fit a tap to one of your barrels yourself. I wouldn't know how though as I'm not much of a /diy/fag.

As for using the water, you could try using it to make beer or some kind of alcohol. It could be pretty cool to have a homebrew where even the water was collected yourself. Plus I guess the alcohol might help to purify it too.
