"BP CTC Tea" combines two grading and processing terms: "BP" and "CTC."
BP: BP stands for Broken Pekoe. It is a grade of black tea where the leaves are broken into small pieces. This grade is slightly larger than BOP (Broken Orange Pekoe), but still indicates that the leaves are broken rather than whole.
CTC: CTC stands for Crush, Tear, Curl, which is a method of processing tea leaves. In this method, the leaves are mechanically crushed, torn, and curled into small pellets. This processing method helps to extract more flavor and color from the leaves, resulting in a bold and robust cup of tea.
