I am slowing turing into my spend-thrift parents from the 80s. They had chickens, sheep, a vegetable garden and my mum bottled in Vacola jars and made yoghurt. I too am making yoghurt and it's really good. So far I've been a handmade yoghurt cheat and I've been using the dried packet cultures. Hansells is the best I've tried so far. I just use the plain/natural ones and add a little fruit sugar and some vanilla extract. It's hells yummy.
Here are some lovely blog posts from other hippy ra ra types who also like to make the goodstuff themselves;
