Is piimä a fermented food?
Yes. Piimä is a Finnish fermented milk: milk soured by mesophilic lactic acid bacteria until it thickens. Like other fermented dairy it is sour and tangy, usually served cold, and used for drinking, baking and dressings. Whether any particular carton still has live cultures depends on the product, so check the label.

Is piimä a fermented food?
Yes. Piimä is a Finnish sour milk product, made by fermenting milk with lactic acid bacteria. The bacteria turn part of the milk sugar (lactose) into lactic acid, which thickens the milk and gives it a clean sour taste. The cultures used are mesophilic, meaning they work at ordinary room temperatures rather than the warm temperatures yogurt needs.
How does the fermentation work?
A home guide describes adding about one tablespoon of finished piimä to a cup of milk, covering it loosely and leaving it at about 70 to 77 F (21 to 25 C) for 12 to 18 hours until it thickens. Dairies also ferment milk with mesophilic lactic acid bacteria and sell it fresh.
How is it different from other fermented milks?
| Product | Texture | Origin |
|---|---|---|
| Piimä | Thin to slightly thick, sour; similar to buttermilk | Finland |
| Viili | Spoonable and stretchy (‘long’) | Finland, Sweden |
| Buttermilk | Thin, tangy | Widespread |
| Yogurt | Thick, made with warm-loving cultures | Widespread |
How do people eat it?
- As a cold drink with meals, which is common in Finland.
- With granola, cereal or fruit at breakfast.
- In salad dressings, baking and sauces in place of buttermilk.
Does fermented mean probiotic?
Not automatically. Fermented simply means microbes changed the food. Probiotic means a product contains live microbes in an amount shown to give a benefit, and that depends on the strain. NCCIH notes that for most conditions it is not known which probiotics help, so do not rely on piimä for any health effect. Heat treatment after fermenting would kill live cultures, so check the label to see whether a product says it has live cultures.
Who should be careful?
Piimä is a dairy product, so avoid it with a milk allergy. People with lactose intolerance react differently, so try a small amount. This is general information, not medical advice.
People also ask
Is piimä the same as buttermilk?
They are similar soured milks, but piimä is a Finnish product made with mesophilic cultures and is not the leftover liquid from churning butter.
Does piimä contain live bacteria?
It is made with live bacteria, but whether they remain alive depends on the product. Check the label.
Is piimä alcoholic?
It is sold as an ordinary dairy drink. Fermentation here is by lactic acid bacteria, not yeast brewing.
