Camellia Sinensis — the evergreen shrub behind every cup of black, green, oolong, and white tea — is more than a plant. It's a journey. Whether you're dreaming of growing your own or curious about how leaves become tea, this guide walks you through every stage, from planting to your first sip.
What Is Camellia Sinensis?
Camellia Sinensis is an evergreen shrub native to East Asia and the source of all traditional teas, including black, green, oolong, and white. Although it isn't common in the US, depending on the cultivar and your climate, you might be able to grow it in your backyard. Even if you don't harvest the tea leaves, it is a pretty plant with mildly fragrant white flowers in the fall to early winter. It is also ideal for hummingbirds, bees, and other pollinators.
Climate Requirements
Climate: Prefers a tropical or subtropical climate, hardiness zones of 7 to 9. If you don't live in such an area, you may want to grow it in a container or greenhouse. It definitely needs protection from frost.
Soil Requirements
Soil: Well-drained, slightly acidic soil with a pH between 5 and 6 is ideal. Tea plants will acidify the soil around them. If you plant them too densely, the soil may become too acidic. Ensure enough room between plants.
Planting and Care
-
Seed or Cutting: Start with seeds or cuttings. These are available through reputable nurseries. Be aware that there are two main cultivars to choose from. Not all nurseries know the difference, but choosing the one best for your climate could make the difference between success and failure.
- Camellia Sinensis Sinensis – this is the more cold-hardy cultivar and is also known as the "small leaf" variety.
- Camellia Sinensis Assamica – this one does better in warmer climates and is known as the "large leaf" variety.
- Sunlight: Ensure partial to full sunlight. In full sun, it will need more water; always ensure the soil is well-drained.
- Watering: Water regularly, keeping the soil moist but not waterlogged.
- Pruning: This is not a requirement, but pruning can be done for shape and to encourage new growth.
Harvesting Leaves
The real magic begins with harvesting. Most harvesting happens in spring, though milder climates may allow multiple harvests. Regular harvesting encourages further growth.
Processing Tea Leaves
Processing tea leaves is an art form that transforms green leaves into various types of tea. Let's explore the basic steps for making black, green, and oolong teas. The following steps cover drying, which is necessary to prevent spoilage if you want to store the tea leaves.
If you just want to pick enough for a cup, drying is unnecessary — you will need a good handful of fresh leaves for a cup of tea. Although it may taste refreshing, it will not taste like teas that undergo the following processing steps. During those steps, chemical reactions occur, leading to flavor changes.
Green Tea
- Plucking: When it comes time to harvest from your plant, carefully pick (pluck) the top two leaves and an unopened bud, known as "two leaves & a bud."
- Initial drying: After plucking, place them on a baking sheet and allow them to air-dry in the shade for a few hours. This is withering, a crucial stage in tea processing. It reduces water content while encouraging the necessary chemical reactions to begin.
-
Steaming or Pan-Firing: The heat from these actions stops the oxidation process, retaining the green color. Avoiding oxidation is the hallmark of green tea.
- Steaming – Steam on the stovetop for about a minute, as you would a pot of vegetables. This method is used for Japanese green teas, producing a greener color and a more vegetal flavor.
- Pan-firing – Heat in a dry skillet for about two to five minutes. This method is used for most Chinese green teas, resulting in a less vibrant green color and a milder taste with a touch of roasted chestnut flavor.
- Rolling: If desired, you may roll the leaves to shape them.
- Drying: Finally, they are dried to lock in the flavor and prolong shelf life. Spread the leaves on a baking sheet and bake at 250°F for about 20 minutes.
- Brew/store: The leaves are now ready to be brewed or stored in an airtight container.
Black Tea
- Plucking: Same as green tea, although you may add an older leaf or two.
- Initial rolling: Roll the leaves between your hands and very gently crush them until they start to darken. This starts the oxidation process that black teas are known for.
- Withering: Leaves are spread out to wilt and soften. Place them on a baking sheet in a cool location for about three days.
- Rolling: Additional gentle rolling will encourage more oxidation.
- Drying: This halts oxidation and prepares the leaves for storage. Bake at 250°F for 20 minutes.
- Brew/store: Same as with green tea.
Oolong Tea
- Plucking: Same as green tea, although you may add an older leaf or two.
- Withering: After plucking, spread the leaves out and leave them in the sun for 30 minutes to an hour. After that, bring the leaves inside and let them rest for up to 10 hours. Stir and shake every hour (to encourage a small amount of oxidation).
- Drying: Bake at 250°F for 20 minutes.
- Brew/store: Same as with green tea.
White Tea
- Plucking: Pluck either only the unopened buds or the bud and one or two young leaves.
- Withering: After plucking, spread the leaves out and leave them in the sun for one to three days.
- Drying: Briefly heat in a skillet for one to two minutes.
- Brew/store: Same as with green tea.
Brewing Your Tea
The final step is brewing your handcrafted tea. See this tea brewing guide for an in-depth look at how to brew different types of tea. Here are some very general principles.
- Amount of tea: If the leaves are dried, use a rounded teaspoon for every six ounces of water. A more precise way is to weigh the tea leaves. Use 2.5 to 3 grams of tea for every six ounces of water.
- Water Temperature: Use water just under boiling for black tea and dark oolongs. Use slightly cooler water for white teas and much cooler (less than 180°F) for green teas.
- Steeping Time: Generally, 1–2 minutes for green tea and 3–4 minutes for other types.
- Enjoy: Savor the unique flavors and aromas of your home-grown, hand-processed tea.
From Your Garden to Your Cup
Growing and processing your own Camellia Sinensis is a gratifying experience that connects you intimately with the age-old traditions of tea making. It's a journey that yields not only a cup of tea but also a deeper respect and appreciation for this timeless beverage. As you sip your homegrown tea, reflect on the journey from leaf to cup, and may it inspire you to explore further the vast, nuanced world of tea.
At Tea Journeys, I celebrate every step of this beautiful journey. Whether you're just starting or looking to refine your tea-making skills, I'm here to guide and support you. Let's keep exploring and savoring the diverse, enchanting world of tea together.
