Tea bags are often the boogeymen of the tea world. We talk about them plenty and often recommend avoiding them in favor of loose leaf tea. That doesn’t mean they don’t have a place in the tea world.

Tea bags are convenient, no mess options that make brewing tea faster and easier. They are often preferred by people who are new to tea while commonly looked down upon by tea masters because of issues with quality.

There is a lot of discussion surrounding tea bags and whether they are a good choice when it comes to tea drinking. Here, we’ll show you the truth about tea bags and how you can use them to your benefit.

What Are Tea Bags?

Tea bags are typically small, porous pouches that contain dried leaves, flowers, or herbs that are infused in hot or boiling water to brew tea. Tea bags are available for a wide variety of teas including true teas and herbal teas.

True teas are all teas made from the leaves of the Camellia sinensis plant including white tea, green tea, yellow tea, oolong tea, pu-erh tea, and black tea. Herbal teas are made from all other plants and include popular favorites such as ginger tea, apple tea, and chamomile tea.

Other popular tea blends such as Earl Grey, raspberry green tea, and masala chai tea are also available in tea bag form.

Tea bags are typically made of filter paper or food-grade plastics. They are occasionally made of silk, although silk is considered to inhibit full flavor development. In Asia, the term tea bag often refers to the paper wrapping or envelopes that contain loose tea leaves. The tea leaves are removed from the packaging and steeped as loose leaf teas.

Tea bags essentially work as a simplified tea infuser. They often include a string that enables easy removal and a small tag with brewing instructions. Most are made of paper fiber and other biodegradable materials.

History of Tea Bags

Tea bags have been used for centuries in the tea industry. The bags were initially developed in the 8th century under the rule of the Tang Dynasty. The first tea bags were made of paper that was folded and stitched by hand into square bags. The paper was used to preserve the flavor and aroma of the tea.

In the western hemisphere, tea bags were first used in the early 1900's. Two women—Roberta C. Lawson and Mary Molaren—filed the first patent for a 'tea leaf holder'. They used stitched mesh fabric to enable the tea leaves to expand and infuse flavor while also making tea brewing more convenient.

Another of the first manufacturers of these tea bags was known as Thomas Sullivan (1). He initially used silk before switching to gauze, which he discovered infused tea leaves more efficiently.

The first company to manufacture tea bags using machinery was the tea company Teekanne in Germany in 1929. By 1930, William Hermanson patented the heat-sealed paper tea bag. It wasn't until 1944 that the rectangular tea bag was invented. Up to this point, all tea bags were small and shapeless sacks.  In 1953, the British tea company Tetley began to mass-produce tea bags.

In modern times, tea bags are available in the small, rectangular shape and in larger sachets and sacks. Circular tea bags are also available with no strings to help limit waste. Teas are also commonly sold in tea tins and large bags similar to coffee bags.

Benefits of Tea Bags


The main benefit of tea bags is that they are convenient. It's easy to pop a tea bag into a hot cup of water or to-go mug and get on with the rest of your day. There's no fiddling around with tea tools or having to wash extra dishes afterward. The handy attached string makes clean up easy as you can just toss the tea bag into the garbage or compost pile.

No Mess

Another benefit of tea bags is that there is no mess. You simply remove the bag and voila—a perfect cup of tea without mucking up the kitchen. If you've used loose tea before, you know that you need a tea infuser or tea strainer to remove the loose leaves. That means you'll have extra equipment you need to clean. Tea bags take the hassle out of making tea by streamlining the process.

Perfect for Iced Tea

Tea bags are particularly well-suited for making iced tea. Brewing iced tea can be a big job, especially if you're adding in fresh fruit or flavorings. Brewing with tea bags makes the process simpler and faster so you can get on to other preparations for a big celebration or backyard tea party.

Drawbacks of Tea Bags

Don't Contain All Healthy Compounds

Unlike whole leaf teas, tea bags generally contain broken leaves, dust, and fannings created during the CTC or crush-tear-curl method of production. The leaves are placed into large rolling machines that break down whole leaves into smaller pieces that fit into tea bags.

Unfortunately, this process results in degradation of the healthy compounds such as such as l-theanine and antioxidants inherent to the tea plant that help to detox and improve overall health. 

Don't Fully Infuse Flavor

Another issue with tea bags is that many of them are too small and they subsequently constrict the tea leaves. Tea leaves release flavor by expanding in water; when the leaves are restricted, they are unable to infuse the flavor as well. This can result in a weaker cup of tea lacking the rich flavor of brewed loose leaf blends.

Getting the Most Out of Tea Bags

Just because tea bags have some drawbacks doesn't mean you can't use them. Drinking tea is all about enjoyment. If you're in a hurry and need to use a tea bag, go for it. Just make sure to follow these guidelines to select the best tea bags that preserve flavor and aroma.

Large, Loose Sachets

Since small tea bags result in inferior flavor, using large sachets instead helps to minimize this drawback. Loose sachets ensure the leaves have plenty of space to expand and infuse flavor. Pyramid shaped tea bags are particularly useful since the tea leaves are free to float around both sideways and vertically.

Quality Construction

Look for tea bags that are unbleached to prevent the alteration of flavors from chemicals. Tea bags that are heat sealed are better than those with metal staples as the metal can affect flavor. If you're looking to cut down on waste, opt for tea bags that don't contain excess wrapping or strings and tags.

High Quality Leaves

Whether you choose black tea bags, green tea bags, or even powdered matcha green tea, the quality of the leaves makes all the difference in brewing. This is true whether you plan on making a cup of tea using loose leaves or tea bags. You can also purchase tea that is certified fair trade to ensure healthy working and growing conditions are established.

Always purchase tea from a reputable company to ensure the best flavor. The tea company should prominently list where the tea comes from and how it was grown. Teas grown in the Philippines will taste different than those grown in China or Africa. That's due to terroir—the idea that climate, earth composition, and other environmental factors affect flavor and aroma.

Fillable Tea Bags

Looking for convenience but don't want to sacrifice quality or flavor? Try T-sacs or other fillable tea bags! These filter-paper pouches allow you to enjoy your favorite high-quality loose teas without the hassle of a steeper or strainer. These tea bags are also great for easy cold brewing!

Tea Bag Verdict

Tea bags are convenient and minimize the mess typically associated with traditional brewing methods. While we still recommend using loose leaf tea whenever possible, you can use tea bags in a pinch.

Tea bags are great when you're in a hurry and simply don't have time for cleanup. Make sure to select tea bags that are large enough to allow the leaves to fully expand and infuse flavor. Opt for tea bags that contain whole leaves to get better flavor and health benefits.

When it comes down to it, the healthiest tea is the tea you drink. Don't skip a hot cuppa just because you don't want to pull out the tea tools. Simply pop in a high-quality, large sachet tea bag and sip to your health.
