"BOPSM" stands for "Broken Orange Pekoe Special Masala," and "CTC" stands for "Crush, Tear, Curl." These terms refer to specific grades and processing methods of black tea.
BOPSM: Broken Orange Pekoe Special Masala is a grade of black tea, often found in the Indian subcontinent. "Orange Pekoe" refers to a high-quality whole leaf tea, but when the leaves are broken, they're graded differently. BOPSM indicates that the leaves are broken, but it's a special grade that might have a bit more leaf and tip content compared to lower grades.
CTC: Crush, Tear, Curl is a method of processing tea leaves. In this method, the leaves undergo mechanical processing where they are crushed, torn, and curled into small pellets. This process helps to extract more flavor and color from the leaves, resulting in a stronger and more robust cup of tea compared to traditional whole leaf teas.
