Doogh is a cold, refreshing drink made from fermented yogurt, carbonated water, and mint. It tastes amazing, and can be made right at home! It has an unmistakable tangy, fizzy, refreshing flavor, and is served with carbonated water over ice (and sometimes with mint). It is popular in Iran during the warmer months as a refreshing and nourishing digestive drink.
It is sometimes called yogurt soda, though the word doogh is derived from the Farsi term doushidant, which means “treaty”.
Many Persian meals end with a glass of doogh or Persian Tea, and it is simple to make at home. In this recipe post, I show you how to make it with either yogurt and milk or with a shortcut method using kefir. If you already love fermented drinks like kefir and kombucha, doogh is perfect for you!
Doogh and kefir are both fermented drinks, and they do have a few key differences. Doogh is a fermented yogurt-based beverage that is typically spiced with mint, salt, and, carbonated water. Kefir is a fermented milk drink that is made with kefir grains and has a tart, sour taste.
🌟Why this recipe works
While it is certainly very refreshing and tastes great, doogh is also said to aid digestion like Mast o Khiar (a Persian yogurt and cucumber dip). I recommend checking out my article on Garm and Sard foods to understand more about Persian food medicine.

👩🍳How to Make This Recipe
Start by adding 1 cup of milk and 1 cup of water to a medium sized saucepan. Heat the liquid until it hits 185F, and don’t let it boil. You can check the temperature using an instant-read thermometer.
Remove the liquid from the heat and allow it to cool to 110F. Then add another cup of milk, yogurt (or kefir), salt, and honey.
Pour the whole mixture into a jar and cover it. If you have a jar lid with a vent, make sure to use it. If not, you will have to vent the jar manually a few times during the fermentation process so the glass isn’t at risk of exploding with the gas buildup.
A quart or 1L size is ideal, but don’t use one bigger than 1/2-gallon or 2L.
Keep the mixture in a dark, warm place for 2-3 days, venting it once a day to be safe (if you don’t have a vent on your lid).
Once those days have passed, run the fermented mix through a non-metal sieve or squeeze it through a nut milk bag. Then, transfer it to a clean quart-sized jar and refrigerate for up to 1 week, venting it every day. It is ready to use immediately.
To serve your doogh, fill a glass with ice. Serve it 1:1 doogh to carbonated or still water. I like to add dried, ground mint to taste just before serving as well as a sprig of mint for a pretty garnish.
Easy shortcut with kefir
Simply mix together store-bought kefir in a 1:1 ratio with carbonated or still water. Kefir is fermented, so it will produce a similar result to this doogh recipe.

This recipe has completely blown my mind! I never thought fermentation could be this simple and never would have thought to make a yogurt soda but the fizzy end result is totally addicting. I shared this with a friend who regularly makes kombucha and she had to have the recipe too.
So glad you liked it, Laurie! I actually found a mint-flavored kombucha last year that reminded me so much of this drink. Thanks for taking the time to share, and enjoy!
I can’t get mine carbonated. Using a 1L clean mason jar and venting twice a day. Any tips?
Hi Monica, the carbonation comes from the sparkling water. The fermented milk (yogurt) mixture gives it the tangy taste. You still need to vent it, because there is a build up of gas from the fermentation, but it won’t be fizzy like the end product that is mixed with sparkling water. I hope this helps!
Thank you for this wonderful recipe. I was wondering once it is fermented in the fridge and ready to add to water or soda can I keep some of this ferment aside and use it to repeat the process?
Great question! Yes, you can use it again to repeat the process and treat it as the kefir in the recipe instructions. However, you will only get up to 3 batches before you need to add new cultures.
