I have a Severin yoghurt maker,
@sharia , and I make a batch every 5 or 6 days. It's a circular container housing 7 individual jars.
I scald two pints of FF milk with 30gg dried skimmed milk powder (whisked in), then I cool the pan of milk in the sink filled with cold water for 3-4 minutes.
I whisk in either a single portion pot of Yeo Valley natural yoghurt, OR a jar of homemade yoghurt from the last batch.
I pour this into a jug and then fill the jars, screwing the lids shut and popping them into the container. Lid on, switch on, set kitchen pinger for 8 hours. I often turn it off after 6 hours and leave it to cool, or if I've done it for 8 hours (no longer as it gets less mild and much tangier the longer you leave it) I take the jars out and put them in a cool place until they're cold enough for the fridge.
Sounds like a faff but really really it's not - I've got into a routine. My pudding every night (because I love it!) is a jar of yoghurt decanted into a bowl with a same-size jar of sugar free strawberry jelly (useful, those jars - I bought a spare set) and some Splenda. Sometimes some cream......
I sometimes strain a jar of it and use the thick thick result instead of creme fraiche in, say, stroganoff, or as a more indulgent Greek-style yoghurt for pudding.
The individual jars suit me WAY better than having to make one big batch in a large container.
