Kefir culture (expired best before) (Clapham MK41)

3 sachets of kefir culture (bb Sept 21)
These are starter sachets which each make about a litre. Used one last week and they are still working fine but you can keep spawning from the one you have so don’t need these. Also have an instruction booklet if it’s your first time making but it’s really simple and creates a yoghurty type drink that’s great for balancing stomach flora.
