Does Spearmint Tea Have Caffeine? Everything You Need to Know Before Your Evening Cup

You know that moment when it’s 9 PM, you’re finally slowing down after a long day, and you want something warm and comforting?

Maybe you’re thinking about making a cup of tea while you relax, read, or watch your favorite show.

But then comes the question:

“Wait… is this going to keep me awake?”

We’ve all been there.

Coffee is obviously off the table for many people at night, but even some teas can sneak in caffeine and leave you wondering why you’re still staring at the ceiling hours later.

That’s why many people reach for spearmint tea. It has that fresh, refreshing taste people love—but without the worry that comes with caffeine.

So, does spearmint tea actually have caffeine?

The Short Answer is...No, Pure Spearmint Tea Does Not Have Caffeine

Pure spearmint tea is 100% caffeine-free.

Unlike traditional teas such as black tea, green tea, and white tea, spearmint tea does not come from the tea plant (Camellia sinensis), which naturally contains caffeine.

Instead, spearmint tea is an herbal drink (often called a tisane) made from the leaves of the spearmint plant, scientifically known as Mentha spicata.

Because it doesn’t contain caffeine, spearmint tea can be enjoyed in the evening without worrying about the typical caffeine-related effects like feeling restless or having trouble falling asleep.

It does have a fresh, uplifting flavor that can make you feel refreshed and alert—but that comes from the natural aroma and taste of the mint, not from a stimulant.

Spearmint Has Been Around for Centuries

Spearmint might feel like a modern wellness trend, but this little green herb has a long history.

The spearmint plant is a hardy perennial that originally grew across parts of Europe and Southern Asia. For generations, people have used it in cooking, traditional remedies, and drinks because of its gentle flavor and refreshing qualities.

Interestingly, spearmint also played a role in American history.

During the American Revolution, many colonists avoided imported British tea because of political tensions and turned to locally grown alternatives. Spearmint became one of the herbs used in what was called “patriot tea,” especially in areas like Connecticut where it was commonly grown.

So that cup of spearmint tea isn’t just a relaxing drink—it has a pretty interesting story behind it too.

What's the Difference Between Spearmint vs. Peppermint?

If you’ve ever stood in the tea aisle wondering whether spearmint and peppermint are basically the same thing, you’re not alone.

They’re closely related, but they are not identical.

Peppermint is actually a hybrid plant created from spearmint and water mint. The biggest difference comes down to flavor.

Peppermint:

• Has a stronger, sharper mint flavor

• Contains more menthol, which gives it that cooling “icy” feeling

• Often feels more intense and refreshing

Spearmint:

• Has a sweeter, softer flavor

• Feels smoother and gentler

• Is often preferred by people who want a mild mint taste

  
  

The good news?

Both peppermint tea and spearmint tea are naturally caffeine-free.

The choice mostly comes down to what kind of flavor you enjoy. If peppermint feels a little too strong, spearmint is often the smoother option.

Why Are So Many People Drinking Spearmint Tea?

Of course, people drink spearmint tea because it tastes good. But many people also enjoy it because of how it fits into their daily routine.

One reason spearmint has gained attention is its connection to hormonal health.

Some research has explored spearmint tea’s potential effects on hormones, especially in people with conditions like PCOS (polycystic ovary syndrome). Some studies suggest spearmint may help reduce levels of certain hormones like testosterone, which is why it is sometimes discussed in relation to hormonal acne and unwanted hair growth.

It’s important to remember that tea is not a replacement for medical treatment, but some people enjoy adding it as part of a balanced lifestyle.

Beyond hormones, spearmint tea is also popular because:

• It can feel soothing after meals. Many people enjoy mint teas when their stomach feels uncomfortable.

• It makes a great evening drink. Since it contains no caffeine, it can be part of a relaxing nighttime routine.

• It avoids the caffeine crash. You get the refreshing taste without the ups and downs that some caffeinated drinks can bring.

Sometimes you don’t need another energy boost—you just want a peaceful moment with something warm in your hands.

How to Prepare Spearmint Tea for the Best Flavor

Making spearmint tea is simple.

For dried spearmint leaves:

1. Add about 1 teaspoon of dried spearmint leaves to your cup.

2. Pour in hot water around 195–205°F (90–96°C).

3. Let it steep for 5–10 minutes.

4. Strain and enjoy.

If you’re using fresh spearmint leaves, you can use around 1–2 fresh sprigs per cup.

You can drink it plain, add a little honey, or enjoy it over ice for a refreshing cold tea.

One thing to watch out for:

Not every “spearmint tea” product is made with only spearmint.

Some tea blends combine spearmint with other ingredients like black tea, green tea, or coffee flavors. Those ingredients can add caffeine.

Before buying, take a quick look at the ingredient list. If you’re looking for a caffeine-free option, make sure spearmint is the only tea ingredient or that the blend specifically says it is caffeine-free.

So...Can You Drink Spearmint Tea at Night?

Yes.

If you’re drinking pure spearmint tea, you can enjoy it in the evening without worrying about caffeine keeping you awake.

It’s naturally caffeine-free, gentle in flavor, and works just as well as a cozy nighttime drink as it does as a refreshing iced tea on a warm afternoon.

So the next time you’re standing in the kitchen at 9 PM wondering what you can drink before bed, spearmint tea is a pretty safe choice.

A little minty freshness, zero caffeine, and a simple moment to slow down—that’s a pretty good combination.
