Our Pet-nat style natural ciders are made using local fruit and leaving the juice to ferment naturally, relying purely on native wild yeasts found on the apples themselves. No temperature control or any added sugar, water, yeast, sulphites, etc. Then we just wait for the right moment to bottle the cider. Both of Lepola Pet-Nat Style ciders "Dry" and "Lingonberry" are certified Finnish Real ciders (aitosiideri.fi).
