10% fat yoghurt?

[db]

The fattiest milk I can buy here has 3.5% fat. I can
also buy 10% fat yoghurt. How do they get it to 10% ?
When I make yoghurt, 1L milk makes 1L yoghurt, so if
I start with 3.5% I end up with 3.5% - unless the
yoghurt fermentation produces extra fat, which I assume
it does not.

So where do the extra 6.5% come from?

It will either be Greek style yoghurt, which has been strained, so 1L
milk will make significantly less than 1L yoghurt, or will have been
made from a mixture of milk and cream.

Thank you! Quick answer, and to the point.

Yeah - I strain mine - I find a 4 pint carton of milk is just the right
size for my slow cooker. Straining through muslin I get a very thick
yogurt and use about half as a cream cheese - lovely!
