Greek style yogurt

This is my second attempt at making a Greek style yogurt, the first attempt was far too thick as it had been strained too much. It was still a great yogurt although far too rich for most people, although Chris loves it. This batch was 5 liters and I decided to let it drain until there was 2.5 liters of whey in the bucket underneath, removing roughly half the volume. I think it worked out pretty well and I made up 5 with blackberry jam, 5 with strawberry jam and 5 natural.
