Ever had trouble keeping your yoghurt and other fermented foods at the right temperature? Us too, so we've worked with designers to create a Mad Millie double-walled, stainless steel culturing flask.

Whip up your next batch of yoghurt, kefir, skyr, kombucha or butter and pop it into this perfectly sized flask. Leave it overnight so the cultures can work their magic and voila! 

Designed to be used with Mad Millie Greek Yoghurt, Coconut Yoghurt, Kefir, Skyr, Cultured Butter and Kombucha Kits.

• Electricity free • Stainless Steel • Temperature Maintenance 

Quantity: 1 L capacity
Size: 13 cm x 13 cm x 20 cm 

Note: The Culturing Flask is designed to fit our newer glass jars. Previous kits included a taller jar which will not fit.
