I don't do it much now but used to homebrew large quantities of beer, cider and wine. It's one of those things that's easy to start but hard to master; in terms of getting the taste good, and if you want to go from ingredients rather than kits.
As others have said making spirits is more complex, and you might need a license.
But to make beer for instance you can just
put sugar,
syrup tin
and hot water
into your fermenting bin,
mix with a long, hygienic (not wooden) spoon,
fill up with lukewarm water,
then 'pitch' yeast (just means sprinkle in, you don't have to do a baseball throw)
and leave the bin in a warm place (near your boiler for instance) for a few days. Depends how warm the place is, if your home is cool it can take a few weeks for best results.
Then siphon the pre-beer into a barrel,
add some 'priming sugar'
and again wait a few days/weeks for the fermentation of the priming sugar to fizz it up and the sediment to settle at the bottom.
There are all kinds of different possible variations but I just kept it very simple. If you have apples in the autumn you can scrat
and press
them, then go through a similar process with the juice to make cider. However it's very slow using hand-tools as I have depicted, so I would recommend automatic machines if you have significant quantities. Especially the press.
Edit: The post won't post with embedded pictures, nor was I able to attach a picture earlier, so I'll leave those spaces blank, and hopefully the issue will soon be fixed and I can add the pix later.
