All you need is a thing called an EasyStill - look on google or e-bay and you'll find one.
In the UK you are allowed to use one to make distilled water for your steam iron.
But, unlike in Scandinavia, you are not allowed to do the following - go onto a home brew site and buy a packet of 'turbo yeast', mix it with about 25 litres of water and wait 10 days for the water to become 20 per cent alcohol.
Then, you musn't run this through the EasyStill, reducing the volume by half to 40 per cent alcohol before adding stuff like Juniper or whatever kind of essence you fancy.
These can be legally obtained through reputable companies on line to produce perfectly good, safe, but untaxed gin, vodka, schnapps etc. (search 'home distilling for them).
The EasyStill costs about £145, looks like a coffee machine and is as safe to use as any other electric ironing accessory on the market.
It's just the revenue boys that get upset because anything over 20 per cent alcohol and you have to pay Gordon Brown protection money. Hence extra sweetness of finished product.
This is the only safe method of producing home made hooch, if you bugger about with flames and stills you will either go completely blind or blow yourself up - and you REALLY shouldn't do that,
Pip pip!
