Yoghurtplant

[K N and P J Harris]

The Kefir plant is a combination of yeast and bacteria - not a plant as 
such. We use the same term in the UK for a culture used for making 
ginger beer, it is called a ginger beer plant but it is still a yeast. 
Suggest you try the microbiology list. Warning, experience of a 
colleague many years ago suggests that making Kefir (the "culture" is 
also sometimes called "Kefir grains") is not that easy and when it goes 
wrong the product is quite disgusting !
