Frequently asked questions

How long do Sourdough Flakes take to activate?
The flakes dissolve in lukewarm water in about an hour, and the culture starts waking immediately. A few simple daily feeds then build it to full baking strength in 5–7 days — no heat mats, gadgets or special equipment required. Because Cintra is a mature culture aged more than a decade, activation is reliable and the flavour is there from your very first loaf.

Is a dehydrated starter as good as a fresh one?
Once active, yes — a well-made dehydrated starter performs identically to fresh. What matters is the quality and age of the original culture. Learn how dehydrated sourdough starter works →

Do I need anything else to get started?
Just flour, water and a jar. Everything else — including the day-by-day Flake-by-Flake Home Baker's Guide — is in the bag.
