RennetAbout us
Natural Probio is all about live cultures: water kefir, milk kefir, kombucha, ginger beer and cheese from your own kitchen. More than 20,000 customers already ferment with us.
What we do
We send live cultures that let you make fermented drinks and cheese in your own kitchen: water kefir grains, milk kefir grains, the kombucha SCOBY and the ginger beer plant, plus liquid calf rennet for cheese. Every order comes with a guide, and behind the shop is a team that knows these cultures well and answers every question, from the first batch to the hundredth.
Water kefir needs only sugar, water and a bit of fruit; milk kefir turns the whole milk you buy anyway into something thick and tangy; kombucha starts from the tea you already have in the cupboard; the ginger beer plant turns fresh ginger into a proper fiery brew; and a few drops of rennet give you a fresh cheese by the evening. Cannot choose? Our sets put the cultures together for less. Not sure where to start? Our page on which ferment suits you helps you decide in a minute.
Our cultures
Our cultures come from traditional methods: unique and vigorous. They start strongly in the first batch and do not hold it against you if life gets in the way for a day. We weigh them out by hand and pack them in small quantities, so they reach you fresh and active.
How we work
- Quick dispatch: your order leaves within 24 to 48 working hours, well protected, and reaches you across the United Kingdom in 3 to 6 working days. Standard tracked delivery costs £4.90 and is free from £35; express tracked delivery costs £14.90.
- Clear prices: every price is in pounds sterling with VAT included, and the delivery charge shows in your basket before you pay.
- Clear guides: quantities, times and signs to watch for, written so it works the first time. Everything else is in our guides.
- A team that answers: send a question or a photo of your jar and you will hear back within one working day.
- Satisfaction guarantee: if your culture does not get going when you follow the guide, we will find a solution with you.
Who is behind the brand
The shop is run by the owner of the brand Natural Probio; full details are in the legal notice. We would rather spend our time on the cultures, the guides and your e-mails than on ourselves, but if you have a question about us, just ask.
