Orange Pekoe One (OP1) is a high-quality grade of black tea, part of the tea grading system that classifies teas based on the size and quality of their leaves. This grade is typically used for orthodox (traditionally processed) teas and is especially common in Sri Lanka (Ceylon), India, and other tea-growing regions.

Key Characteristics of OP1:

1. Grade Type:

   • OP1 refers to whole-leaf black tea. It is slightly more refined and higher in quality than standard Orange Pekoe (OP). The “1” signifies a finer, more uniform version of OP tea leaves.

2. Leaf Appearance:

   • Long, wiry leaves that are well-twisted, thin, and even.
   • The leaves are larger compared to BOP grades, giving the tea a more delicate and elegant appearance.

3. Flavor Profile:

   • OP1 teas are known for their light, subtle flavors compared to broken or fannings grades.
   • Typically smooth and mellow, with a hint of sweetness or floral notes, depending on the origin.
   • High-grown OP1 teas from regions like Sri Lanka or Darjeeling often have a bright and aromatic profile.

4. Brewing & Usage:

   • Best enjoyed as a light, straight black tea without milk or sugar to appreciate its delicate flavors.
   • A favorite for tea drinkers who prefer a mild, soothing cup over a strong and brisk brew.

5. Production Regions:

   • Frequently produced in Sri Lanka, especially from high-altitude regions like Nuwara Eliya, Uva, and Dimbula.
   • Also grown in India (Assam, Darjeeling) and some parts of China or Kenya.
