Every week somebody holds up a jar of turmeric in the shop and asks whether the bright one is the good one. It almost never is. Colour in ground turmeric is the easiest thing to fix and the last thing worth trusting, which is why our buyers do not look at it first.
What The Buyers Actually Check
The first test is a fingernail. Press a pinch of powder against the back of your hand and rub it in. Fresh turmeric stains and keeps staining; tired turmeric sits on the skin and brushes off. The curcumin that gives it colour is oil-soluble, and once it has gone the powder has nothing left to bind with.
The second is smell, but not the way most people do it. Do not sniff the jar. Put a small amount in your palm, close your hand, breathe out onto it, then open it. The warmth releases the volatiles, and if there is nothing there the lot is old regardless of how it looks.
A lot that fails the palm test is not bad turmeric. It is last year's turmeric being sold as this year's.
Why The Harvest Month Matters
Turmeric is lifted between November and January and it is at its best for about eight months after that. Nothing about the powder tells you where in that window you are, which is why every Biharat label carries the month the lot was lifted rather than a generic best-before date eighteen months out.
The Three Things To Buy On
Harvest month, curcumin percentage and whether it was whole when you bought it. Lakadong turmeric runs above seven percent curcumin, which is roughly double the national average, and that number is worth asking for because it is measurable rather than a matter of taste.
If a shop cannot tell you when a lot was lifted, that is the answer to your question.

12 March 2026The fingernail test is the one I never knew. I have been buying on colour for years and wondering why the curry tasted flat.

13 March 2026Colour is the easiest thing to fake, which is exactly why it is the worst thing to buy on. Glad it was useful.

15 March 2026Any chance of the same piece for cardamom? I can never tell an old pod from a new one until it is already in the pot.
