WHAT IS TEA?

The World's Most Popular Beverage

Tea is one of the oldest, most fascinating, and most widely consumed beverages in the world. Yet many people don't realize that every traditional tea comes from a single plant.

Every traditional tea—whether green, black, white, oolong, yellow, or pu-erh—comes from:

Camellia sinensis

The differences in color, flavor, aroma, and body are created by how the leaves are harvested, processed, and oxidized after picking.

A Brief History of Tea

Tea originated in China more than 4,000 years ago and eventually spread throughout Asia, the Middle East, Europe, and the Americas.

For thousands of years, tea has been enjoyed for its flavor, tradition, and cultural significance.

Today, tea is grown in many regions around the world, including:

  • China
  • Japan
  • India
  • Sri Lanka
  • Taiwan
  • Kenya
  • Vietnam

Each growing region contributes unique flavors influenced by climate, soil, elevation, and centuries of processing traditions.

The Six Traditional Types of Tea

Green Tea

Fresh.

Green tea is minimally oxidized, helping preserve its natural color and delicate flavors. Expect fresh, grassy, vegetal notes with a naturally sweet finish.

Examples: Sencha, Dragon Well, Jasmine Green Tea

Black Tea

Bold.

Black tea is fully oxidized, creating darker leaves and a rich, full-bodied cup with malty, robust flavors.

Examples: English Breakfast, Assam, Earl Grey

Oolong Tea

Balanced.

Oolong tea falls between green and black tea. Depending on the level of oxidation, it can range from light and floral to rich and roasted.

White Tea

Delicate.

White tea is the least processed of all traditional teas. It offers a smooth, naturally sweet cup with subtle floral notes.

Yellow Tea

Rare.

Yellow tea is one of the rarest traditional teas. Its unique slow-drying process creates a mellow, exceptionally smooth flavor.

Pu-erh Tea

Aged.

Pu-erh is a fermented tea known for its earthy, complex flavors that continue to evolve over time.

Did You Know? Herbal Tea Isn't Actually Tea

Many beverages sold as "tea" contain no Camellia sinensis leaves at all.

These beverages are technically called:

Herbal Infusions (Tisanes)

Common ingredients include:

  • Hibiscus
  • Chamomile
  • Peppermint
  • Rooibos
  • Fruit blends
  • Spices
  • Flowers

Popular Grave Shift herbal offerings include fruit-forward blends such as Grimberry Hibiscus.

What Determines Tea Flavor?

Growing Region (Terroir)

Climate, elevation, rainfall, and soil all influence a tea's character and flavor.

Harvest Season

Spring harvests often produce brighter, sweeter teas, while later harvests can create deeper, more robust flavors.

Processing Method

Oxidation, drying, rolling, roasting, and aging dramatically shape the final cup.

Brewing Method

Water temperature, steeping time, and the amount of tea used all influence flavor, aroma, and strength.

Why Loose Leaf Tea?

Loose leaf tea typically contains larger, higher-quality leaves than standard tea bags, allowing the leaves to fully expand during brewing.

Benefits include:

✓ Better flavor

✓ More complex aroma

✓ Multiple steepings

✓ Larger, whole leaves

✓ A richer brewing experience

At Grave Shift Coffee & Tea, we carefully select premium loose leaf teas for exceptional quality, freshness, and flavor. Whether you're beginning a shift, ending a long day, or simply taking a well-earned break, every cup is crafted to deliver an experience worth slowing down for.

Every Leaf. Every Story.
