Question 1

What is C5 grade Ceylon cinnamon?

Accepted Answer

C5 is a Continental-grade Ceylon True Cinnamon bark with a quill diameter of 10 mm to 12 mm. It ranks as the third highest grade in the Continental series, below C5 Extra Special and C5 Special, and is characterised by a smooth roll, deep yellow colour, and a sweet, delicate flavour.

Question 2

How is C5 different from C5 Special cinnamon?

Accepted Answer

C5 Special has a smaller quill diameter (typically under 10 mm) and represents a more refined level of peeling skill. The flavour profile is similar, but C5 Special releases its essential oils more gently due to the thinner, more tightly rolled layers. C5 is more widely available and priced lower than C5 Special.

Question 3

Is Ceylon cinnamon C5 grade safe to eat daily?

Accepted Answer

Ceylon cinnamon contains very low levels of coumarin compared to cassia, making it widely regarded as safe for regular dietary use. Most health authorities distinguish Ceylon cinnamon from cassia on this basis. As with any spice, moderate, culinary-level quantities are recommended.

Question 4

What is the diameter of C5 cinnamon quills?

Accepted Answer

C5 grade cinnamon quills measure between 10 mm and 12 mm in diameter. This diameter range is what defines the grade within the Continental grading system used for Sri Lankan cinnamon exports.

Question 5

Can I use C5 cinnamon quills for making cinnamon powder?

Accepted Answer

Yes. C5 quills can be ground into powder using a spice grinder or mortar and pestle. Because the bark is thinly rolled in multiple layers, it grinds more easily than cassia. The resulting powder has a lighter colour and milder, sweeter flavour compared to commercially blended cinnamon powders.

Question 6

Where is C5 grade cinnamon produced in Sri Lanka?

Accepted Answer

Most Ceylon cinnamon, including C5 grade, is cultivated in the Southern and Western provinces — particularly around Matara, Galle, and Kalutara. Hand-peeling communities in these regions have practised the traditional technique for generations, and the skill of the peeler directly affects the grade of the finished quill.

Question 7

How many times can I reuse a C5 cinnamon quill for infusions?

Accepted Answer

A C5 quill's multiple bark layers mean it can typically be steeped two or three times before its flavour is spent. Rinse and dry the quill after each use and store it in an airtight container. The intensity will diminish with each steeping, which many people prefer for lighter teas or drinks.

Question 8

How do I store C5 cinnamon barks to keep them fresh?

Accepted Answer

Keep C5 quills in an airtight glass or ceramic container away from direct sunlight and heat. Stored this way, whole quills retain their aroma and flavour for up to two years. Ground cinnamon made from C5 bark is best used within six to twelve months for optimal flavour.
