This crisp, light botanical tea is a blend designed to soothe and energize at the same time. Green leaves from the yerba mate plant, an evergreen tree in the holly family, are dried over a fire and then blended with organic peppermint leaves to produce a refreshing sweetness that coats the tongue with each calming sip. Yerba mate naturally contains caffeine.

In Brazil, yerba mate is particularly grown in the southern states of Paraná, Santa Catarina, and Rio Grande do Sul, which have the ideal humid subtropical climate for this plant. Brazilian yerba mate is a staple beverage in many parts of the country, especially in the southern regions.

Peppermint is widely cultivated in the United States, particularly in the Pacific Northwest and upper Midwest regions, where the climate and soil conditions are ideal for growing this fragrant herb. Oregon and Washington are two of the largest producers of peppermint, along with areas in Michigan and Indiana. The U.S. peppermint industry is known for its high-quality crops.

This tea offers a gentler option for those seeking the comforting warmth and taste of tea without a pronounced caffeine boost. While naturally much lower in caffeine than traditional black or green teas, decaf varieties still preserve the soothing aromas and subtle flavors that tea is known for. Whether sipped in the early morning or enjoyed as a mellow evening indulgence, decaf tea provides an easygoing alternative that allows tea lovers to savor familiar comforts at any time of day. With each cup, you can relish the same beloved qualities of tea—aroma, ritual, and gentle satisfaction—while keeping caffeine intake to a minimum.

Dried, Cut & Sifted

This method focuses refinement and versatility. The leaves are carefully dried to preserve their natural character, then cut for a more concentrated infusion. Sifting ensures a smooth, even texture, allowing the flavors to fully unfold. The result? A tea that’s clean, consistent, and effortlessly brewable—whether steeped strong or slow, it delivers depth with every sip.

Yerba mate is a traditional South American tea made from the dried leaves and stems of the Ilex paraguariensis plant, a type of holly native to regions of Brazil.
Yerba mate has a distinctive flavor that can be described as earthy, herbal, and grassy. It can have vegetal or green tea-like qualities with a slightly bitter or smoky note, especially when prepared in traditional ways.

The flavor can be somewhat strong and acquired due to the bitterness from the tannins and sophisticated herbal flavors. The intensity of the flavor depends on the type of yerba mate and how it's prepared.

Yerba mate contains a moderate amount of caffeine, making it a natural stimulant.
Yerba mate also contains theobromine, the stimulant found in chocolate, which contributes to feelings of alertness and focus but is often less intense than caffeine.

Yerba mate is packed with polyphenols, which are compounds with antioxidant properties that can help fight oxidative stress and inflammation. This may contribute to the anti-aging and health-supporting effects of yerba mate.

Peppermint is a popular herb known for its cooling, refreshing, and invigorating qualities. It is a hybrid between watermint and spearmint and is often used in a variety of teas, either on its own or as part of a blend. When added to tea, peppermint brings a crisp and aromatic flavor profile that enhances both the taste and health benefits of the drink.
Peppermint has a natural cooling effect, which can be felt as a tingling sensation in the mouth, especially after sipping the tea. The flavor of peppermint is minty with hints of sweetness, though it also carries a sharpness that adds brightness to the tea. It has a distinctly herbal aroma with earthy undertones, and it pairs well with both herbal teas and green teas.

395 BOXES

Our year-round rigorous sourcing allows us to have an evergreen blend with a flavor profile of high quality while retaining our commitment to seasonal coffees. This amount of cupping and blending takes a considerable amount of time, but we think it makes the difference and is a system we use for all our blends.

YERBA MATE
Yerba mate is a traditional drink in Latin and South America with indigenous roots traced back to the Guaraní and Tupí peoples in Paraguay. The yerba mate in this blend is grown in Brazil, where cultivators are also known as ervateiros in Brazilian Portuguese. The yerba mate, leaves of the Ilex paraguariensis tree, naturally contain caffeine, but with these pre-dosed tea sachets, the caffeine content is less than a cup of brewed coffee. We find that the natural vegetal flavor of yerba mate paired with peppermint leaves creates a balanced and refreshing cup of tea.

TISANES (HERBAL TEA)
Tisane is the French word for herb, and it is commonly used to describe herbal teas. Herbal teas are infusions made from steeped flowers, herbs and other plant materials. Naturally, most tisanes do not contain caffeine; although a few do, such as yaupon and yerba mate. A true tea must be prepared from the Camellia sinensis plant, then processed for a resulting white, yellow, green, oolong, or black tea.

ABOUT THE SACHETS
The pyramid tea sachets are designed to give the tea leaves ample room to unfurl & expand as they steep. These sachets are made from PLA Mesh (NeoSoilon®) material that is derived from 100% non-GMO sugar cane. Each sachet is pre-dosed so you can enjoy a great cup of tea at your convenience.

Green Cost

The price here reflects not only the labor of growing and cultivating the tea, but also the respective farm’s years of skilled handling, quality of regional cultivars, and oftentimes processing work that may include milling, drying, steaming, oxidation process, and more. We partner with friends like Savoy Tea Company to identify quality teas, where within we seek to uphold transparency and quality. Due to the varying weights of each type of tea, at this time, we are listing the rough cost for each tea box.

This tea was purchased at $80 per kilogram.

Transportation Cost

This number represents the cost incurred while the tea was moved from the producing country to Onyx Coffee Lab in Arkansas. The price listed below is the cost we incurred per box of tea via designated express micro-lot shipping by air transport. It varies for each tea based on the overall volume and density of the shipment.

The air transport rate was $50/kg.

Production Cost

The following list includes many of the costs associated with producing this tea. We have always maintained transparency as a principle but have often lumped these things under the label of “production costs” in the past without going into detail.

There is an inherent difference in handling tea versus coffee, where most teas are fully processed at a processing facility in the region or at the tea farm itself. There is intensely skilled labor that comes with the drying, oxidation, rolling, steaming and packing processes. Tea is also physically very delicate, and extra care is taken in handling each dried leaf or bud to maintain the structural integrity of tea.

While the following list isn’t exhaustive, hopefully, it gives you a picture of the work, expense, and investment involved in executing tea at the level that we do. At this time we are listing our cost of production for each pound of tea at around $3.40. There are obviously many other aspects of running a business such as breakage, mistakes, new equipment and maintenance, but this works as an arbitrary cost associated with making one box of tea.

Fixed Costs
These are costs associated with simply having a business. Things like utilities of internet, natural gas, phones, rent, business licenses, fees, etc. These things increase every year. For example, most commercial leases increase by 2% every year. We periodically look at these costs and try to reduce expenses, but work in this area are small moves of the needle as these are mostly the same and usually increase every year.

Packaging
This is all the things that go into packaging the tea to get it safely to your home. There’s the biodegradable bag, the recyclable box, the compostable mailer, different boxes for bulk shipping, the paper that pads the tea, tape, and a few odds and ends. (Read about our new retail packaging HERE). These costs are separate from the tea, but a part of the cost of producing tea that is packed well and ready to ship and consume. We want our teas to arrive in a secure fashion, looking like it did when it left Onyx: with style and design but also keeping the environment in mind. Shipping packages inevitably have waste associated and we’re working towards sustainability at each step.

Labor
At Onyx, we work to make jobs both sustainable and celebrated, and we pay salaries, provide health insurance, and give regular raises to our staff. Often we have a handful of staff that get celebrated, but everyone on our team contributes and is valuable. Likewise, we wish to pay our tea partner, Savoy Tea Co, for all their skilled labor in tea handling (from hand massaging oils to create phenomenal Earl Grey or the careful packaging of each tea box). Onyx is not just a brand or a design or a café, we are truly made by every person we work with.

We all know it takes work to make anything. Savoy’s sourcing approach echoes our own, which has more labor involved than you may think. Because we visit every Relationship Coffee producer, that means our green buying team of Jon and Dakota typically spend a total of six months traveling. We’re committed to visiting and cupping on the ground, this inevitably is an investment of time, of money, of long layovers, of encountering government coupes and protests, and forging some of the greatest friendships and seeing some of the most beautiful landscapes imaginable. We appreciate that in working with the Savoy Tea team, Bill and Kyle, put equal dedication into sourcing these teas.

We have a creative team that helps create all things visible, digital, and print. These folks are very talented and have really helped push the dream of Onyx to the next level. We believe that tea can inherently be great, but having something that looks and feels good helps inform expectations, helps bring value, and tells the stories in this way has tangible and important value.

These are a few of the jobs we feel really have more involvement than might be imagined, but throughout Onyx there are touch points of intentionally positioned team members to help create the best possible beverage experiences.

Taxes
We all know what this is. We set aside and submit money every quarter for taxes along with paying all of the weekly and monthly taxes we are obligated to pay. This can be tough for a small business as there are ebbs and flows in cash flow, and taxes are often not paid in conjunction with the sales season.

Lot Size

Lot size informs us of one thing: the size of that lot. Forming a single farm lot can often take just as much labor and experience as the large regional blends, depending on the level of labor or quality standards applied to each day or week’s pickings.

A great example of this would be matcha powder, which is often a carefully constructed sum of processed green teas that are often grown in different sections of a farm to create a balanced and intentional matcha experience. It may be built up of many different farms. This often signifies that the lot was built to reflect the flavor characteristics or unique cultivars of the region. Meanwhile, a larger lot size of a Yunnan black tea may end up being used in a variety of different teas, based on the final processing and any additional treatments before packaging.
