In this article
Meet Lapte acru de casă, Romania’s homemade soured milk — a gently tangy, refreshing drink with deep roots in the country’s rural kitchens.

Simple, wholesome and endlessly satisfying, it is the kind of everyday classic that turns a humble ingredient into something special.
About Lapte Acru de Casă
Lapte acru de casă, the traditional Romanian soured-milk drink, delights not only with its distinctive flavour but also with its excellent health benefits. It is made from fresh, unsweetened milk and marked by a pleasantly gentle tang. The drink is rich in probiotic cultures that are essential for healthy digestion. Refreshing and easy-going, it makes a wonderful companion to savoury dishes or a lovely treat enjoyed entirely on its own.
Ingredients (serves 1–2)
- 1 litre fresh, unsweetened milk
- 1–2 tablespoons buttermilk, or a piece of sourdough starter
- A clean glass jar with a lid
Shopping for the ingredients
To make lapte acru de casă, it is important to choose quality ingredients. When buying the milk, make sure it is fresh and unsweetened so the natural flavour comes through. Buttermilk or sourdough starter is just as important, as it acts as the starter culture. These ingredients are easy to find in most supermarkets or regional food shops.
Preparing the dish
Preparing lapte acru de casă is quick and straightforward. Once you have everything to hand, set out a clean glass jar to make the drink in. It is important that the jar is sterilised to keep unwanted bacteria at bay. The mixture is usually adjusted to suit the conditions and your own preferences, so that everyone can enjoy its full flavour.
Step-by-step instructions
- Pour the fresh milk into the glass jar.
- Add the buttermilk or sourdough starter and stir well.
- Cover the jar with a lid or a clean cloth to allow fermentation.
- Place the jar somewhere warm (around 20–30°C) and leave it for 24–48 hours.
- Check the consistency and taste regularly.
- Once it has reached the tanginess you like, move the jar to the fridge to stop the fermentation process.
Gluten-free / lactose-free version
Lapte acru de casă is naturally gluten-free, as it is made only from milk and the starter. For a lactose-free version, choose lactose-free milk, which gives the same consistency and flavour as the original. Many people with a lactose intolerance can also benefit from the probiotic properties of the buttermilk, which are kind to the digestion. If you prefer, you can even reach for plant-based alternatives to adapt this drink.
Tips for vegans and vegetarians
While lapte acru de casă is traditionally made from animal milk, vegans can find creative alternatives to craft their own plant-based version. Instead of cow’s milk you might use almond or oat milk, both of which offer a refreshing, nutrient-rich base. There are also special vegan kefir starter cultures that mimic the fermented effect. That way vegans, too, can enjoy a delicious drink that echoes the flavours of traditional Romanian cooking.
More tips and tricks
Another key factor in making lapte acru de casă is the temperature. Make sure the room where the jar stands is warm enough to encourage fermentation, as temperatures that are too low can slow the process right down. The choice of starter also shapes the final result. Experiment with different amounts and types of buttermilk or sourdough starter to find the level of tanginess that is just right for you.
Adapting the recipe to your taste
Some people love to refine the flavour of lapte acru de casă with extra aromas. This might mean adding spices such as cinnamon or vanilla for a sweeter note, or fresh herbs for a more savoury twist. Pieces of fruit or a spoonful of honey can make an interesting and tasty addition too. Give your creativity free rein and adapt the recipe to your own personal taste.
Ingredient substitutions
If you do not have buttermilk to hand, you can also use yoghurt as a starter culture. Simply mix a tablespoon of yoghurt into the milk to achieve the same effect. As for the milk, you can choose between different types, such as whole milk or low-fat milk, depending on your taste and dietary preferences. Make sure any alternatives are fresh to get the best results.
Drink pairing ideas
Lapte acru de casă pairs wonderfully with a variety of foods. It goes especially well with hearty dishes such as grilled vegetables or a warming vegetable soup. It is also a perfect match for traditional Romanian dishes like Sarmale or Mămăligă. For an extra touch, finish it with fresh herbs or a squeeze of lemon.
Serving and presentation ideas
Just as the taste of lapte acru de casă is unique, its presentation can be memorable too. Serve the drink in clear glasses that show off its creamy, gently tangy character. You can also use fresh herbs or fruit as a garnish to make the drink look as good as it tastes. A decorative plate of matching snacks beside the glass rounds off the whole picture and is sure to impress your guests.
A bit of history
The story of lapte acru de casă reaches back into the traditions of the Romanian country kitchen. This drink was especially popular in rural areas, where people often produced their own milk. Fermentation was a practical way to preserve milk while at the same time encouraging useful probiotic cultures. Today it is prized in towns and cities too, and remains an important part of Romanian cuisine.
