Common questions about CTC tea grades

What is Assam CTC tea?

Assam CTC tea is black tea from the Assam tea belt made by the Crush, Tear, Curl method. The leaf is cut into small granules that brew quickly into a strong, malty, deep-coloured cup, which is why it is the standard tea for Indian chai and milk tea.

Which CTC tea grade is best for chai and milk tea?

For a strong cup of chai, buyers usually choose BOP or BP for long-brewed tea, and PD or Dust where the tea must brew in seconds, as at tea stalls and canteens. Many blenders mix a leaf grade with a dust grade to balance body and colour.

What is the difference between BOP and BOPSM?

Both are broken orange pekoe grades. BOP has the largest particles and gives the fullest body. BOPSM (small mixed) is slightly smaller and brews a brighter, brisker liquor.

What is the difference between PF, PD and Dust?

They are the three smallest CTC grades. PF (pekoe fannings) is the largest of the three and is widely used in tea bags. PD (pekoe dust, also called PF Dust) is finer and brews faster. Dust is the finest and gives the most colour and strength in the shortest time.
