Your main expense is likely to be a couple of glass demijohns - you can make wine in a plastic fermentation bucket like beer but it's not good practice, as you need to fill your container almost to the top to avoid oxidation. Other essential bits of equipment - rubber bungs, airlocks etc can be bought very cheaply. I managed to get a pile of demijohns from my OH's parents - they used to make a lot of wine but no longer - so ask around a few folks because it's the kind of thing people don't tend to part with even for many years and there's probably a few folk have them up in the attic.

You probably have a shop near you that sells the main bits of equipment - to start off with you could buy a kit (around £20) that has most of what you need, or you could go down the country wine route and gather berries/fruit to make wine with - there are lots of recipes on the internet.

If you start getting into it, CJJ Berry's book on Winemaking for beginners is excellent, and not just for beginners!

Good luck!

PS - bit of crossover with last post - was writing the above while Alison was writing her post - spooky or what!
