Chai concentrate is the cheat code for chai lovers. It captures the bloomed-spice flavor of traditional masala chai in a refrigerator-stable format that takes 30 seconds to serve. One 30-minute cooking session makes about 14 servings.

Unlike most store-bought concentrates (Tazo, Oregon Chai), this version is unsweetened — you control the sugar at serving time, and most of the spice flavor doesn't get drowned out.

Ingredients

Makes about 4 cups (1L) of concentrate, enough for ~14 servings:

• 5 cups water
• 3 tablespoons loose-leaf black tea (Assam preferred — CTC for strength, orthodox for nuance)
• 20 green cardamom pods, gently cracked
• 3 cinnamon sticks (about 3 inches each)
• 15 whole cloves
• 15 whole black peppercorns
• 4 thin slices fresh ginger (about ¼ inch thick each)
• 2 star anise (optional, for a slightly licorice note)
• 1 vanilla bean, split (optional)

Method

1. Toast the spices. In a heavy-bottomed pot, dry-toast the cardamom, cinnamon, cloves, peppercorns, and star anise over medium heat for 90 seconds, until fragrant. This blooms the volatile oils and dramatically deepens the final flavor.
2. Add water and ginger. Pour in the 5 cups of water and add the ginger slices and split vanilla bean if using. Bring to a boil, then reduce to a simmer for 15 minutes. The water should reduce by about 20% and turn deep amber.
3. Add the tea. Drop in the loose tea, stir, and simmer for 5 minutes more. Don't go longer — the tannins start turning bitter at 8+ minutes.
4. Strain. Pour through a fine-mesh strainer into a heatproof jar or pitcher. Let cool to room temperature before sealing.
5. Refrigerate. Sealed in a glass jar in the fridge, the concentrate keeps for 2 weeks.

How to serve

Hot chai latte

• 4oz concentrate + 4oz hot milk + sugar to taste = single serving
• Heat the milk to 65°C / 150°F before adding for the best foam
• Adjust ratio to taste — some people prefer 1:2 concentrate-to-milk for a milkier drink, others 2:1 for a stronger one

Iced chai

• 3oz concentrate + 5oz cold milk + ice + 1 tsp simple syrup if you like sweet
• Shake in a cocktail shaker for foam, or just stir

Dirty iced chai

• 2oz concentrate + 1 shot espresso + 4oz cold milk + ice

Chai oatmeal / smoothies

• Use 2oz concentrate as the liquid base for steel-cut oats or in a banana-yogurt smoothie

Storage and shelf life

The concentrate keeps:

• Refrigerated: 2 weeks in a sealed glass jar
• Frozen: 3 months — freeze in ice cube trays for single-serving portions

If the concentrate looks cloudy or develops a sour smell, discard it — that's bacterial growth. The high tannin content makes spoilage rare in the first 14 days.

Variations

Vegan-ready

The concentrate itself is vegan. Use oat milk (preferably barista grade) when serving for the best texture. Coconut milk overpowers the spices.

Decaf

Use decaf Assam or Ceylon black tea. The spice flavor is unaffected; you lose only the caffeine.

Spicier

Add 1 dried red chili to the spice mix in step 1. Roughly equivalent to Maharashtrian street-vendor heat.

Sweeter

Add ½ cup of jaggery or brown sugar in step 2 (with the water). Resulting concentrate is sweet and only needs unsweetened milk to serve. Cuts shelf life to 10 days.

What to do with the spent spices

The strained spices have given up about 70% of their flavor but still have some left. Reuse them once: same recipe, but with fresh tea added. The second batch is gentler, lower-caffeine, and good for kids or evening drinking.

Why this beats store-bought

• Cost: ~$3 for 14 servings vs $1.50–2 per serving from a cafe
• Sugar control: Tazo and Oregon Chai are 24g+ sugar per serving. Yours is 0g until you add it
• Freshness: Whole spices toasted yesterday vs powdered spices that lost their aromatics months ago
• Customization: Adjust to your preferred spice balance
