What is Chai Tea?

Chai tea combines black tea with a variety of spices. This tea blend often contains ginger, cloves, cardamom, and cinnamon. It may also include allspice, anise, fennel seed, white pepper, or nutmeg.

On Amazon, you can buy chai tea powders, tea bags, loose leaf tea and more.

Although chai tea can be served with milk and sugar, many tea drinkers enjoy this beverage black.

In addition to regular chai tea, you can also order chai tea lattes. These can be served hot or iced. Hot chai tea lattes combine chai tea, steamed milk, and foam. They may also include flavor shots like vanilla. 

Iced chai tea lattes combine chai tea and milk. Some coffee houses also serve frozen chai lattes that blend together chai tea, milk, and ice.

A dirty chai tea latte is any chai tea latte that contains added shots of espresso. Dirty chai lattes can be served hot or iced, just like their standard counterparts.

How Much Caffeine is in Chai Tea?

Let’s turn to the question that probably brought you here: how much caffeine is in chai tea?

In general, chai tea typically contains between 30-70 mg of caffeine in an 8-ounce cup, but there’s no definitive amount since many factors affect its caffeine content. 

Most chai tea blends use black tea, which is its only source of caffeine. According to researchers and tea experts, the category of tea (black tea, green tea, white tea, etc.) doesn’t determine the amount of caffeine in tea since it varies drastically within families of tea. In fact, it’s a myth that black tea contains more caffeine than green tea.

Rather, caffeine content depends on the specific tea used and how you brew it, contrary to many sources online.  This is why you’ll see so many different answers to the question in this blog post.

Depending on how you brew black tea, its caffeine content depends on brewing temperature, the amount of leaves, and how long you steep it. In most cases, tea bags contain more caffeine than loose leaf tea.

Even the ingredient ratios will affect the amount of caffeine since additional ingredients can dilute the actual amount of black tea in the chai tea.

To give some examples of chai tea’s caffeine content, let’s look at some popular brands. Bigelow’s Vanilla Chai contains between 30-60 mg of caffeine. Tazo has a Classic Chai blend that contains between 31-45 mg of caffeine.

Chai Five even has an Organic Chai Herbal Tea that contains no caffeine. However, herbal “tea” does not contain leaves from the Camellia sinensis plant so it’s not technically tea.

How Much Caffeine is in a Chai Tea Latte?

As with chai tea, the answer to this question depends on similar factors. I couldn’t find a definitive answer to this question, but have read estimates between 30 mg to 50 mg of caffeine in an 8-ounce cup.

If the chai tea latte is made with regular black tea, then its caffeine concentration relies on the type of black tea, how it’s brewed, the ratio of ingredients, and the size of the drink. 

However, many chai tea lattes are made from concentrates, which make things more complicated. Others are made from powders, which tend to have more caffeine than concentrates.

As an example, the short chai tea latte (8 oz) at Starbucks has 50 mg of caffeine (the grande has 70 mg with 12 oz). My understanding is that their chai tea comes as a concentrate of tea and spices. 


As discussed, the amount of caffeine in your chai tea or chai tea latte will vary based on several factors.

In general, expect for an 8-ounce cup of chai tea to have between 30-70 mg of caffeine. You can also expect for an 8-ounce chai tea latte to have between 30-50 mg.

These amounts will vary based on the type of black tea, how it’s brewed, the ratios of ingredients, and the size of the drink.
