What is boba tea?

Boba tea is a fun, fruity drink that can use a variety of teas as a base. Most commonly, black, green, or oolong tea is used as a boba tea base which is served cold. Some places call this bubble tea, tapioca tea, or pearl tea, which refers to the small “boba pearls” found at the bottom of the drinks. These pearls are made from tapioca or cassava starch and sugar and are sometimes sweetened with sugar syrup.

Boba tea is made by shaking the pearls within the tea, which fall to the bottom of the cup, and blending the tea with milk to create a creamy drink. The end product is a delicious treat that is fruity and refreshing. Boba tea is usually served with a thick plastic straw, which is thick enough to allow the boba pearls to make up the straw.

In terms of the creamy portion of your boba tea, you’ve got quite a few options. Non-dairy options such as oat milk and coconut milk add just the right amount of creaminess to boba tea. However, some people prefer dairy cream or standard milk too. Many boba stores also let you customize the flavor of the boba itself in your drink, offering varieties like Taro Boba or Strawberry Boba, which means you craft up your personalized boba tea drink the same way you order a personalized coffee at your local Starbucks.

As you learn about the world of boba tea, it’s only natural to wonder if boba tea contains caffeine. After all, it is a “tea” — and you want to be sure you’re not consuming too much caffeine in a day (especially if you are also drinking coffee, tea, or energy drinks). The short answer is yes, but the amount of caffeine varies. Since most teas have naturally occurring caffeine, how much caffeine your boba drink has will depend on the type you order. Let’s explore the caffeine content in a few popular boba tea varieties:

Green tea boba

Boba tea uses green tea as a base and usually has between 20 and 30 mg of caffeine, which can vary depending on the size and how long the tea was steeped. Some boba tea shops may offer decaf green tea as an option if you’re not interested in consuming any caffeine at all. Some popular varieties of green tea boba drinks include matcha bubble tea, which pairs great with whole milk or oat milk.

Oolong tea boba

Oolong tea also contains a light amount of caffeine, generally around 25 to 35 mg per cup. Many people describe oolong tea as a hybrid between green and black tea. Some popular varieties of oolong boba tea drinks include honey oolong boba tea or creamy oolong boba tea.

Black tea boba

Black tea naturally contains more caffeine than green tea and oolong tea, so opt for a black tea base for your boba drink if you’d like a bit more of an energy boost. Most black tea boba drinks contain about 40 to 50 mg of caffeine per cup (again, this varies based on size and the time it was steeped). Even at 50 mg of caffeine per cup, this is still far less caffeine than the average cup of coffee at 85 to 100 mg of caffeine. This is ideal for a mid-afternoon boost that contains a small bit of caffeine, but not enough to leave you feeling restless or jittery. Some popular varieties of black bubble tea drinks include a classic milk bubble tea or black sesame bubble tea.

Why does coffee make me sleepy? How caffeine can leave you feeling tired
What to do when coffee has the opposite effect
man who is tired

Coffee is the most popular stimulant in the U.S., consumed by nearly 75% of Americans. As a long-time coffee drinker, there's no doubt that it's my favorite stimulant (even if its effects are unnoticeable due to my crazy high caffeine tolerance). Even though I crave coffee's taste, with a slight bitterness and light sweetness, based on taste alone, I sometimes reach for coffee simply for a major boost of energy from its caffeine content.

At times, I feel perkier after a cup of coffee, but there are also times I'm struggling to stay awake. This phenomenon has left me questioning," Why does coffee make me sleepy?" If you've felt that random wave of tiredness hit you after consuming caffeine, you might have asked yourself this question, too. The question of how coffee and tiredness are interrelated can get confusing, especially given coffee's well-known reputation as a drink that keeps you awake. Here are a few reasons you might feel tired after drinking coffee.

Can you make great coffee in a single serve? Klatch Coffee’s answer
Is there a better option than K-Cups?
Crazy Goat coffee

While K-Cups can be appealing to coffee drinkers who value convenience at home or in the office, they're not the right choice for everyone. Although it's a fast and easy way to prepare a single cup of coffee, there are a few downsides to the system — namely that K-cup pods can be difficult to recycle (and while refillable pods exist, that depends on the user choosing that option, which isn't always a given considering quick and convenient are two of the main appeals of the system). We interviewed Klatch Coffee's expert roaster, Heather Perry, to learn more about the specialty roaster's approach to single-serve coffee.
Klatch Coffee's single-serve coffee alternatives

Klatch Coffee's single-serving Bruvi pods make it easy to enjoy high-quality, specialty coffee wherever you are. The brand has partnered with a few select providers who share their vision, one of which is Bruvi.
"Bruvi is an improved pod coffee system with a couple of unique features," Perry said. "First is taste and quality; the proprietary brewing system brews to the same high standards as specialty coffee roasters like Klatch Coffee, including adjusting the brewing parameters to match our brewing recipe. That’s why premium coffee from roasters like Klatch is offered on the Bruvi platform. Second, Bruvi’s B-Pods are enzyme-infused and designed to be tossed in the trash, making them guilt-free. B-Pods degrade faster in the landfill without leaving microplastics behind."
It’s also worth noting that for coffee drinkers who only want a single cup at a time, single-serve brewing can be more efficient on resources like water, coffee, and energy. Pre-portioned coffee doesn’t spill, and machines only heat the water needed for a single cup. There’s no waste from discarding leftover coffee from a large pot.
