Tea Blending Certificate
Professional Tea Blending Certification
Blend teas people ask for again
Learn to formulate, taste, document, and sell professional tea and herbal blends, from your first base tea to a market-ready signature recipe, with a Heart of Herbs certificate at the end.
The Professional Tea Blending Certification is a fully online, self-paced program from Heart of Herbs Herbal School, taught by clinical herbalist and certified aromatherapist Demetria Clark. You learn the craft the way working blenders practice it: by weight, by workflow, by the cup, and with the labeling and compliance habits that keep a tea business out of trouble.
Every enrollment includes the complete course, a tea sampler kit shipped to your door for students in the United States, and two additional printed books to keep on your blending bench.
Why Choose Our Tea Blending Certification?
Heart of Herbs Herbal School has been teaching herbalists since 1998 and is an American Herbalists Guild Approved School and a NAHA Approved School. We have trained professional tea formulators for major tea companies worldwide.
Who this course is for
This certification was built for people who want to make tea that is good enough to sell, serve or recommend, not just good enough to drink.
- Herbalists and aromatherapists who want the formulas they hand clients to taste good enough that people actually finish them
- Tea shop, café and farm-stand owners ready to replace bought-in blends with signature recipes of their own
- Product makers and wellness entrepreneurs who need consistent, scalable, compliantly labeled blends
- Home blenders and tea lovers who are tired of guessing and want a repeatable method
- Doulas, massage therapists, yoga teachers and other wellness professionals adding a tea line or a tea service to their practice
No previous tea or herbal training is required. If you already study with Heart of Herbs, this course slots in alongside any of our herbalism or aromatherapy programs.
What you will learn
The course is organized around a seven-step blending workflow you will use on every blend you ever make, with a reference library of charts behind it.
The Seven-Step Blending Workflow
- Define the purpose and flavor profile. Decide who the blend is for, when it will be drunk, and how it should taste before you touch a jar.
- Select your base. Choose among true tea bases (green, black, oolong, white, pu-erh) and caffeine-free herbal bases, matched to purpose and brewing method.
- Choose accents and supporting herbs. Build flavor layers and balance bitter, astringent, and sour notes without losing the character of the plant.
- Add aromatics and flavor enhancement. Work with flowers, citrus peel, spices, vanilla, and natural flavorings, and learn when a blend needs scenting rather than more ingredients.
- Blend by weight and document the recipe. Convert cups and spoons into grams, account for herb density, and record a formula you can repeat and scale.
- Brew, taste and refine. Cup your blend the way professionals do, using the brewing, aroma, and sensory reference charts, then adjust and taste again.
- Label, package and store. Write compliant descriptions, assign lot numbers, choose packaging, and set shelf-life expectations.

Why learn tea blending at Heart of Herbs
Most tea blending courses teach tea. This one is taught by a clinical herbalist who has spent nearly three decades making blends that people actually drink.
A note from Demetria
I have made brilliant, perfectly reasoned, therapeutically flawless tea blends that people poured down the sink. Taste is not a frivolous concern. It is the delivery mechanism. My rule for every blend I send out the door is that I have to want a second cup. Not “I can get this down.” Want. That standard has improved my work more than almost anything else I have adopted, and it is the standard I will teach you to hold.
Demetria Clark, Clinical Herbalist, Certified Aromatherapist, Founder of Heart of Herbs Herbal School
What sets this program apart
- Taught from the herb side and the tea side. You learn true teas and herbal bases together, so you can blend a black tea chai and a caffeine-free evening tisane with the same confidence.
- Compliance built in. Labeling, lot numbers, recordkeeping and claim-free product language are taught as part of the craft, not as an afterthought.
- Blend by weight, every time. Repeatable formulas you can scale from a single cup to a wholesale batch.
- Charts you will actually use. Brewing, pairing, density and conversion references designed to be printed and kept at your blending station.
- A school with a track record. Heart of Herbs has trained tens of thousands of students worldwide since 1998, is an American Herbalists Guild Approved School and a NAHA Approved School, and is a veteran and military spouse owned business.
- Taught in a real voice. Warm, first-person, clinically grounded instruction from the author of Herbal Healing for Children and four other books.

Frequently asked questions
Do I need herbal training first? No. The course starts with tea types and basic brewing and builds from there. Experienced herbalists will move quickly through the early modules and spend more time on formulation and documentation.
When does it start? Whenever you enroll. No cohorts or start dates.
How long does it take? Most students finish in eight to twelve weeks at a few hours a week. There is no deadline.
What is in the tea sampler kit? A selection of tea bases and blending botanicals chosen to match the course exercises. Exact contents change with seasonal availability.
I live outside the United States. What do I receive? The complete course and the tea sampler kit. The two additional printed books are included for US shipping addresses only. International students may be asked to cover customs or shipping differences on physical items.
Can I sell the blends I make? Yes. The course covers formulation by weight, scaling, compliant labeling, and recordkeeping specifically so your blends are ready for market. You are responsible for meeting the regulations where you live.
Is there a final exam? There is a final blending project rather than a written exam. You formulate, document, brew, taste, and label a signature blend and submit your completed workflow forms.
Does this count toward other Heart of Herbs programs? The Professional Tea Blending Certification is a stand-alone certificate course. It complements our herbalism and aromatherapy programs and is a popular add-on for enrolled students.
