CO YO™ Coconut Milk Yoghurt

From their Facebook page:
CO YO was produced to supply the market with a yoghurt that is dairy free.
Most cultures produced for the commercial market are plant based grown on skim milk.Ours are plant based grown on skim milk then on coconut milk. CO YO is 100% coconut milk, NO DAIRY MILK.CO YO was not developed for the vegan market although we have lots of vegans eating it.
But I will agree with the Facebook user name Anais Hatch: I can appreciate your sentiments but it's still produced using a dairy product which is not cruelty free so I am choosing not to eat it, sorry.Plenty of other vegans will agree with me.Kingland dairy manage to make soy yoghurt without growing the culture on milk, so it can be done.
It depends how pedantic you want to be - I tend to be pedantic LOL
As for chocolate - Whittakers Dark Ghana is vegan and so is the dark Peanut Slab and they are yummo
