Beer and Wine making. Though time consuming and fiddly, it can, when sampling the end results be rewarding and fun! There is a lot of equipment needed even to start. Most good suppliers will do good starter kits that will produce a drinkable drink, but as you progress you will find you need to source more equipment.
There is also a fair amount of knowledge needed to make alcohol, so it might be worth pointing out a few good books to get you started.
