How to Make Tea Concentrate at Home (The Russian Zavarka Method)
Russians have been making tea concentrate since the 17th century. Brew it once, use it all week — for hot tea, iced tea, and lattes. Here's the method, the ratios, and everything you need to know about making tea concentrate at home.
The Tradition Behind the Technique
Tea concentrate has been a daily ritual in Russia since at least the 17th century — long before anyone thought to put it in a Mason jar and call it a hack. The traditional method centers on a samovar, a metal urn used to heat water continuously throughout the day.
The process works like this: a small teapot sits on top of the samovar, filled with a very strong brew of tea steeped for an extended time. This concentrated tea is called zavarka. When someone wants a cup, they pour a small amount of zavarka into their glass and dilute it with hot water from the samovar below — adjusting the ratio to their taste.
The result is that the same pot of concentrated tea can serve an entire household across an entire day, each person getting exactly the strength they want. It's one of those ideas that turns out to be brilliant the more you think about it.

Why Make Tea Concentrate at Home?
- Brew once, drink all week. Make a quart of concentrate on Sunday and your perfect cup is 30 seconds away any morning after that.
- Iced tea on demand. Pour concentrate over ice, add cold water, done. No waiting for hot tea to cool down — no watered-down result from ice melting too fast.
- More economical. You use fewer leaves per cup than you would brewing individual mugs — the concentrate method extracts more efficiently.
- Consistent strength every time. Brew it right once and every cup from that batch is the same quality — no more guessing or over-steeping a tired tea bag.
The Tea Concentrate Ratio
The rule for making tea concentrate at home is simple: 1 teaspoon of loose leaf tea per 1 ounce of water. This is significantly stronger than a standard brew and that's intentional — the concentrate gets diluted when you use it.
| Batch Size | Water | Loose Leaf Tea | Cups of Concentrate |
|---|---|---|---|
| Small batch | 16 oz (2 cups) | 16 tsp (~5 Tbsp) | ~6–8 servings |
| Quart Mason jar | 32 oz (4 cups) | ~⅓ cup | ~12–16 servings |
Serving counts vary depending on how strong you like your tea — the beauty of the zavarka method is that each person adjusts their own ratio.
Water Temperature by Tea Type
Water temperature matters more for concentrate than for a standard brew because you're steeping for longer — the wrong temperature on a green or herbal tea will turn it bitter. Here's what to use:
Black Tea — 210°F (just off the boil)
Water that has just come to a boil but isn't yet rolling. Steep for 2–3 minutes. Black tea can handle higher temperatures — this is what gives it that bold, robust character that holds up well in concentrate form. Java Momma's black tea collection works particularly well for concentrate — strong enough to hold their flavor profile through dilution.
Green Tea — 170°F (steaming but not simmering)
Water that is steaming hot with small bubbles forming at the bottom of the pot but not yet simmering. Steep for 2–3 minutes. The lower temperature produces a potent concentrate without the bitterness that boiling water pulls out of green tea.
Herbal Tea — 170–200°F (depends on the blend)
Most herbal teas are more forgiving on temperature than true teas — flower and fruit-forward herbals can handle closer to boiling, while delicate blends do better at 170°F. Check your specific tea for guidance. Herbal concentrates make excellent iced tea bases — berry herbals especially.
No thermometer? Just off the boil (still steaming, barely stopped bubbling) = approximately 210°F. Steaming hot but not yet simmering = approximately 170°F. Both are easy to spot visually without any equipment.
How to Make Tea Concentrate at Home
You don't need a samovar. Any of these methods work:
Teapot with infuser basket
Fill the infuser basket with your tea at the concentrate ratio. Heat water to the appropriate temperature and fill the pot. Steep for 2–3 minutes and remove the basket. Transfer to a sealed jar and refrigerate.
French press
Add loose leaf tea at the concentrate ratio, pour in the appropriately heated water, steep 2–3 minutes, then press and pour into a sealed jar. Clean and simple with no additional straining required.
Mason jar and strainer
Add tea to a Mason jar, pour in hot water at the right temperature, steep 2–3 minutes, then strain through a fine mesh strainer into a second jar. Seal and refrigerate.
Cold brew method
Use cold or room temperature water with a higher ratio of tea (about 1.5 tsp per oz), steep in the fridge for 8–12 hours, then strain. No heat required — produces a naturally sweeter, less astringent concentrate. Works particularly well for green and herbal teas.
Storage:
Tea concentrate keeps in the fridge for up to one week in a sealed jar. Label it with the date and tea type — future you will appreciate it.
How to Use Your Tea Concentrate
Hot tea (the zavarka way)
Fill a mug one third of the way with tea concentrate. Add boiling water to fill. Adjust the ratio to your preferred strength — more concentrate for stronger, less for lighter. This is exactly how the Russians have been doing it for centuries and it works.
Tea latte
Use warmed milk of choice instead of water — whole milk, oat milk, or coconut milk all work well. The concentrate is strong enough to flavor the milk without getting lost in it. Froth the milk before adding for a proper latte texture.
Iced tea
Fill a 16 oz glass with ice. Add ¾ cup tea concentrate. Top with cold filtered water — or milk for an iced tea latte. The concentrate is strong enough that the ice won't water it down the way pre-brewed iced tea does.
Sparkling tea
Use sparkling water instead of still — ginger ale works particularly well with black tea concentrate. Add fresh fruit to the glass for color and a non-alcoholic tea sangria that's genuinely impressive in a wine glass.
Tips Worth Knowing
- Black tea makes the strongest concentrate. If you want a concentrate that holds up through dilution and ice, black tea is the most reliable choice — it has the body to stay flavorful even when cut significantly with water or milk.
- Berry herbals make the best iced tea. If your goal is iced tea, fruit and berry herbal blends produce a naturally sweet, vibrant concentrate that needs no added sugar.
- Don't over-steep. 2–3 minutes is the sweet spot even for concentrate — longer steeping pulls bitterness from the tannins, which gets amplified rather than diluted when you drink it later.
- Try it in a wine glass. Iced tea in a proper wine glass with fresh fruit is a genuinely good non-alcoholic alternative for anyone who wants something more interesting than water at a dinner table.
- Label everything. Tea concentrates can look remarkably similar in the fridge. A small piece of tape with the tea type and date saves future confusion.
The zavarka method has been around for four centuries for a reason — making tea concentrate at home is genuinely one of the smarter things you can do for your daily routine. Brew once, adjust to taste every day, and never sit through a substandard cup again. The Russians figured this out in the 1600s. Might as well catch up.
Frequently Asked Questions
What is zavarka tea concentrate?
Zavarka is the Russian word for a strong tea concentrate brewed at a much higher tea-to-water ratio than a standard cup — typically 1 teaspoon of loose leaf tea per ounce of water. It is made in a small teapot that sits on top of a samovar and diluted with hot water to taste when served. The method allows one brew to serve an entire household across an entire day, with each person adjusting their own strength.
What is the ratio for making tea concentrate at home?
Use 1 teaspoon of loose leaf tea per 1 ounce of water. For a quart Mason jar of concentrate, that's approximately ⅓ cup of tea leaves to 32 oz of water. The concentrate is then diluted when serving — fill a mug one third with concentrate and top with hot water, or use ¾ cup concentrate per 16 oz iced tea glass.
How long does homemade tea concentrate keep in the fridge?
Up to one week in a sealed jar in the refrigerator. Label it with the date and tea type — tea concentrates can look similar after a few days in the fridge. Cold brew concentrate may last slightly longer since it was never heated, but one week is a safe guideline for all methods.
What temperature water should I use for tea concentrate?
Black tea: 210°F — water that has just come to a boil but isn't yet rolling. Green tea: 170°F — steaming hot but not yet simmering. Herbal tea: 170–200°F depending on the blend. The temperature matters more for concentrate than for a standard brew because you're steeping longer — using boiling water on green tea will make a bitter concentrate that stays bitter through dilution.
Can I make tea concentrate with tea bags instead of loose leaf?
Yes — use approximately 4–5 standard tea bags per 16 oz of water for a concentrate ratio. Loose leaf tea generally produces a better concentrate because the leaves have more room to expand and release flavor, but tea bags work fine for a quick batch. Remove the bags after 2–3 minutes just as you would with loose leaf.
