How to Make Cold Brew Tea: Oolong, Plum, Lemon & Mint

Cold brew tea is already the cool kid on the block, but sometimes even cool kids like to dress up. That’s where infused cold brew recipes come in: one tea, one fruit, one citrus, and one herb. Think of it as the golden rule of DIY cold brews. Simple, balanced, and endlessly customizable.

Today, we’re taking that rule and turning it into something magical: Oolong Plum Lemon Mint Cold Brew Tea. It’s fruity, citrusy, herbaceous, and powered by the silky, floral notes of Kapemai’s Darjeeling Oolong. Basically, it’s like bottling up summer in your fridge.

Why This Combo Works

The general rule for crafting cold brew infusions is beautifully straightforward:

• 1 Tea (your base, your backbone, your leading character)
• 1 Fruit (natural sweetness, juiciness, personality)
• 1 Citrus (zesty brightness that wakes up the flavors)
• 1 Herb (a fresh lift, a little surprise note at the end)
  

In this recipe:

• Tea: Kapemai Darjeeling Oolong Tea - smooth, floral, layered with gentle sweetness.
• Fruit: Ripe Plums - juicy, tart, and luscious.
  Citrus: Lemon - zingy, refreshing, balancing the plum’s sweetness.
• Herb: Mint - cooling, crisp, and bright.

The result? A cold brew that’s sophisticated yet playful, refreshing yet indulgent.

The Oolong Plum Lemon Mint Cold Brew Recipe

Ingredients (makes 1 litre / 4 cups):

• 1 litre (about 4 cups) of cold or room-temperature filtered water
• 2 ripe plums, sliced (no need to peel unless you want to)
• 1 lemon, sliced into wheels (use 2 lemons if you enjoy a slightly bitter zest kick)
  
• A handful of fresh mint leaves
• 8–10 grams (about 3 tablespoons) of Kapemai Darjeeling Oolong Tea
• Optional (for serving): sugar syrup or honey, to taste

Steps:

1. Add the oolong tea, plums, lemon slices, and mint leaves into a clean glass bottle or jar.
2. Pour in the cold water until everything is covered.
3. Seal the jar and give it a little shake (don’t worry, the tea won’t mind).
4. Place it in the fridge and let it infuse for 12–24 hours. The longer, the bolder.
5. Strain out the tea leaves, fruit, and mint.
6. Pour into a glass and add sugar syrup or honey at this stage, if you’d like to sweeten.

Pro tip 💡: Save the strained plums as a tangy topping for yogurt or smoothies. Waste not, sip more.

What Makes Oolong the Star Here?

If you’ve never tried cold brewing oolong, prepare to be impressed. Unlike black tea, which can go bold and malty, or green tea, which stays crisp and grassy, oolong sits somewhere in the magical middle.

Kapemai’s Darjeeling Oolong in particular offers:

• Floral notes that mingle beautifully with mint.
• Light sweetness that balances the tartness of the plum.
• A smooth body that holds up to long infusions without bitterness.

This is why oolong makes one of the best teas for cold brew; it’s complex but forgiving, mellow yet layered. Perfect for playful infusions like this one.

Flavor Profile: What to Expect

Once you take that first sip of this oolong plum lemon mint cold brew tea, here’s what will dance on your taste buds:

• A fruity burst from the ripe plums, juicy, slightly tart, and refreshing.
• A zesty zing from lemon, adding brightness and balance.
• A cooling wave of mint that lingers, making it feel extra refreshing.
• The floral, smooth backdrop of oolong ties everything together.

It’s like the tea version of a summer garden party, inviting, vibrant, and leaving you wondering why you don’t do this more often.

Customization Tips

The beauty of cold brew tea is that you’re in control. A few ways to make it your own:

• Sweeter? Add a spoonful of honey or a splash of sugar syrup while serving, not during steeping.
• Bolder? Steep closer to 24 hours instead of 12.
• More citrus? Add two lemons instead of one for a sharper, zestier kick.
• More herbal? Try basil instead of mint for an Italian twist.

Cold brew isn’t strict; it’s flexible, forgiving, and ready to adapt to your mood.

The Health Bonus

Besides being delicious, this infusion brings along some health perks:

• Oolong tea may support metabolism and digestion.
• Plums are packed with antioxidants and vitamin C.
• Lemon boosts hydration and adds a vitamin C punch.
• Mint helps with digestion and keeps things feeling fresh.

Basically, it’s a spa day for your insides.

Cold Brew Tea Recipe Rule of Thumb

Remember the golden ratio for creating your own cold brew blends at home:

👉 1 Tea + 1 Fruit + 1 Citrus + 1 Herb

Once you’ve nailed this Oolong Plum Lemon Mint recipe, experiment with your own combinations. Apple + lime + rosemary with green tea? Mango + orange + basil with black tea? Your fridge is your playground.

Why Quality Tea Matters

Here’s the thing: cold brew is slow, gentle, and deliberate. It extracts flavors carefully over hours, which means if your leaves are stale, dusty, or mass-produced, the result will taste flat (or worse, bland).

Using a good loose-leaf tea makes all the difference. With Kapemai’s Darjeeling Oolong, you’re tasting single-origin leaves grown in small batches, carefully processed for quality. That’s why your cold brew turns out smooth, vibrant, and genuinely refreshing.

Ready to Brew Your Own?

This Oolong Plum Lemon Mint Cold Brew Tea is proof that cold brewing is more than just tossing leaves in water; it’s about creating your own flavor story. And the best part? With a handful of ingredients and a little patience, you can have café-level tea waiting in your fridge.

So grab your jar, slice those plums, and steep some magic with Kapemai’s Darjeeling Oolong because life’s too short for boring beverages.
