Does Bubble Tea Have Caffeine?

Main Ingredients of Bubble Tea

To understand whether bubble tea contains caffeine, let’s explore the main ingredients in boba tea.

Tea Base

The tea base is the foundation of bubble tea and can be made from black, green, oolong, or even herbal teas. The type of tea used will have a direct impact on the caffeine content of the final product.

Milk or Creamer

Milk or creamer adds a creamy texture and richness to bubble tea. Dairy milk, plant-based milk, or non-dairy creamers are often used, depending on personal preference and dietary restrictions.


Bubble tea is typically sweetened with sugar, honey, or flavored syrups. The level of sweetness can be adjusted to individual taste preferences.


Toppings are what make bubble tea distinctive and fun. Some popular choices include chewy tapioca pearls, fruit jellies, and popping boba, which are fruit juice-filled spheres that burst in your mouth.

The Role of Caffeine in Bubble Tea

Caffeine is a natural stimulant found in tea leaves, coffee beans, and other plants. It stimulates the central nervous system, increasing alertness and reducing fatigue. In bubble tea, caffeine comes primarily from the tea base. The exact amount of caffeine in bubble tea will vary depending on several factors.

Caffeine Content in Average Bubble Milk Tea

When considering the mg of caffeine content in an average bubble milk tea, it’s important to remember that various factors influence the total amount of caffeine. However, we can provide an estimation based on typical serving sizes and ingredients.

A 16-ounce serving of bubble milk tea made with a black tea base, which is the most common choice, contains approximately 50 to 80 milligrams of caffeine. This estimate is based on the assumption that black tea contains an average of 47 milligrams of caffeine per 8-ounce cup.

Keep in mind that this estimation can vary depending on factors like the type of tea used, the brewing process, and the serving size. Additionally, other ingredients in bubble milk tea, such as milk or creamer and sweeteners, do not contribute to the overall caffeine content.

To put the caffeine content of bubble milk tea into perspective, it generally falls between the caffeine levels found in green tea (25-45 mg of caffeine per 8 ounces) and coffee (95 milligrams per 8 ounces). This makes bubble milk tea a moderate source of caffeine, suitable for those who desire a slight energy boost without the stronger effects of coffee.

Factors Influencing Caffeine Content

Type of Tea Base

Different tea varieties contain varying amounts of caffeine. Black tea typically has the highest caffeine content, followed by oolong tea, green tea, and white tea. Herbal teas, on the other hand, are usually caffeine-free.

Preparation Method

The caffeine content in tea can be affected by the brewing process. Steeping tea for longer periods or at higher temperatures can extract more caffeine from the tea leaves.

Serving Size

The size of your bubble tea will also impact the total caffeine content. Larger servings will naturally contain more caffeine than smaller ones.

How Much Caffeine is in Bubble Tea?

The caffeine content in bubble tea can range from 20 to 100 milligrams per serving, depending on the factors mentioned earlier. For comparison, an 8-ounce cup of coffee contains around 95 milligrams of caffeine.

Caffeine-Free Bubble Tea Options

If you want to enjoy bubble tea without the caffeine, there are several options available:

  1. Choose herbal tea as your base, which is naturally caffeine-free.
  2. Opt for a fruit-based drink without tea, such as fruit smoothies or slushes with boba toppings.
  3. Ask your local bubble tea shop if they offer decaffeinated tea options.
