What You'll Need

The Cold Brew

  • 57 grams of coffee beans
  • 16 oz water
  • Mason jar with lid
  • Fine mesh strainer
  • Coffee filter
  • Bowl

The Simple Syrup

  • 1 cup coconut sugar
  • ½ cup water
  • Saucepan
  • Candy thermometer
  • A jar or other small storage container with a lid

The Bobas

The Boba Cold Brew

  • ¼ cup cold brew
  • ½ cup milk or cream
  • 2 tbsp bobas
  • Simple syrup or other sweetener of choice (Optional)
  • Ice cubes or coffee cubes (Optional)
  • A glass

Method

The Cold Brew

  1. Begin by grinding your beans on a very coarse setting, so that they resemble something like breadcrumbs.
  2. Add the coffee and then the water into the Mason jar.
  3. Give it a quick stir.
  4. Let it sit for 12 - 24 hours.
  5. Strain the coffee using the mesh strainer.
  6. Strain the coffee again, this time using the paper strainer.
  7. Dilute the concentrate, usually at a 1:2 ratio of coffee to water.
  8. Keep in fridge until ready to use.

The Simple Syrup

  1. Now we’ll make the simple syrup. Start by boiling the water in the saucepan over medium heat.
  2. Add coconut sugar and stir constantly until the candy thermometer reads 230 degrees Fahrenheit. This usually takes under five minutes, so keep a close eye out!
  3. Once it’s hot enough, take the saucepan off of the heat and let the syrup cool.
  4. Once cool, pour into your storage container and keep in the fridge until you’re ready to use.

The Bobas

  1. Now we come to the bobas themselves. Bring the water to a boil in the saucepan.
  2. Add in the bobas, stirring steadily until they begin to float.
  3. Turn the heat down to medium and let them cook for between 12 and 15 minutes.
  4. Once done, take them off the heat and let them sit for another 15 minutes.
  5. Drain the excess water and pour the bobas into the bowl.
  6. Pour the simple syrup over the bobas until they’re submerged and let them soak for a minimum of 15 minutes. Keep them in the fridge until you’re ready to make your boba cold brew.

The Boba Cold Brew

  1. At this point, you’re ready to make the drink itself! Put the bobas at the bottom of your glass.
  2. Add the cold brew and milk/cream.
  3. If desired, add ice cubes or coffee cubes and/or sweetener.
  4. Enjoy!

Extra Notes:

  • Timing: plan your drink ahead. The cold brew ideally takes at least 12 hours to make, so you’re going to want to start that part of the process well in advance of everything else.
  • While we suggest making your cold brew in a Mason jar, there are actually several ways you can do this. Just pick a style that works for you!
  • The simple syrup should last up to 6 months in the fridge.
  • The trick for properly boiling the bobas is to always use 2 cups of water to every ¼ cup of tapioca pearls. So, if you want to make a larger batch, just follow that ratio!
  • The bobas are the chewiest in the first few hours after they’ve been cooked (that gummy bear texture is what you want). You can use them after this point – as long as you keep them refrigerated – but be warned that they’ll harden over time and become crunchy in the center.

What is Boba / Bubble Tea?

Boba, or bubble tea, is a frothy, cold beverage with either black or green iced tea as its base. Sweetened milk and other various flavors are often added in as well.

But, while that sounds delicious all on its own, that’s really just a flavored iced tea.

What makes it a “boba” tea is the main attraction: tapioca pearls.

These little black balls, or “pearls”, bring a new level of excitement to the drink, and have been the driving force behind boba tea’s recent meteoric rise in popularity.

Here’s a great video with some visuals of boba tea. If you look closely, while it has some differences, the process of making boba tea is very similar to the boba cold brew! Although, of course, it’s missing the coffee part… so we’ll pass and leave that to all you tea lovers out there.


The next time you find yourself torn between a boba tea or a cold brew, you won’t have to make that choice! Just whip up a boba cold brew and you’ll be good to go.

We’d love to hear your thoughts on this one. Did you try it? Do you want to try it? What variations, if any, do you plan on using?
