An authentic Alphonso mango is the right variety from the right place, ripened without carbide, from a seller you can check. Ratna Alphonso is shorthand for Ratnagiri Alphonso. We sell it by the dozen from Rs 1,849, with GI Authorised User certificate AU/5974/GI/139/260.
"Authentic" is easy to print on a box and hard to prove from a photo. This page breaks it into parts you can check: the variety, the origin, the ripening method and the seller. It also says what a home test can and cannot tell you. Searchers often write "Ratna Alphonso" or "Ratna amba". That is shorthand for Ratnagiri Alphonso, the fruit also called Hapus or Hafoos.
What authentic means
Four things sit under the word. Each has its own evidence, and one cannot stand in for another.
| Part | What it means | How to check |
|---|---|---|
| Variety | The fruit is Alphonso, also called Hapus | Ask the seller for the variety by name and the grower region |
| Origin | Grown in the Ratnagiri and Devgad belt of the Konkan | Ask for a named district or taluka and a GI authorisation number |
| Ripening | Ripened naturally, not with carbide | Ask how it was ripened, and read the regulation |
| Seller | A licensed business that answers questions | Look for an FSSAI licence, a postal address and a contact number |
Alphonso is named after Afonso de Albuquerque. Fruits generally weigh 150 to 300 g, and the pulp is rich, creamy and non-fibrous. Named varieties such as Alphonso are propagated by grafting, so the variety is a property of the tree, not of how the fruit looks. That is why a photo alone proves little.
The GI credential
A Geographical Indication protects the name of a product that comes from a defined place. For Alphonso, the GI Registry lists Devgad Alphonso Mango as application 379, merged with the Alphonso Mango application, GI No. 139. We hold GI Authorised User certificate AU/5974/GI/139/260 (GI No. 139). Our Brand Facts page states the GI Registry certificate details we hold.
What a GI does and does not tell you: it is evidence about origin and the right to use the name. It is not a statement about ripening, and it does not replace an FSSAI licence. A seller's GI authorisation is a number you can ask for. Our guide to the Alphonso GI tag goes further.
Hay-ripened or carbide-ripened
Ripening is where many buyers worry most, and where the law is clear. Selling fruit ripened with acetylene (carbide) gas is prohibited in India. Ethylene up to 100 ppm is the permitted alternative. The table sets out the two approaches side by side.
| Point | Naturally ripened on hay beds | Ripened with calcium carbide |
|---|---|---|
| Ripening medium | Mature fruit is laid on hay beds and ripens by itself over several days. | Calcium carbide produces acetylene gas, which is used to force ripening. |
| Legality in India | Allowed. | Prohibited. Regulation 2.3.5 of the Food Safety and Standards (Prohibition and Restrictions on Sales) Regulations, 2011 bars selling fruit ripened with acetylene (carbide) gas. |
| Skin colour (rough clue, not proof) | Often uneven: green, gold and a blush can sit together on one fruit. | Colour alone cannot show how a fruit was ripened; an even bright yellow skin is only a rough clue. |
| Aroma (rough clue, not proof) | A sweet fruity smell, strongest near the stalk, builds as the fruit ripens. | Aroma can be weak when ripening is forced; this is a rough clue only. |
| Health note | Ripened by the fruit itself. | The Ministry of Health and Family Welfare (PIB, 18 May 2024) lists dizziness, irritation, difficulty in swallowing and vomiting among effects linked to carbide residues. |
We do not use carbide. Our Alphonso mangoes are ripened naturally on hay beds. No home test, including the water or bucket test, proves how a mango was ripened. Ask any seller how the fruit was ripened, and expect a plain answer. Read our guide to carbide-ripened mangoes and our guide to artificial ripening.
Home checks and their limits
People ask for a quick test. There is no reliable one, but a few observations help you ask better questions.
- Smell near the stalk. A ripe Alphonso smells sweet and fruity. A weak smell on a soft fruit is worth a question to the seller, not a verdict.
- Colour. Alphonso can be green, gold and blush on one fruit. A uniform bright yellow is a rough clue, not proof.
- The press test. A ripe fruit gives slightly under a gentle press. A fruit that is soft and watery at the skin may be overripe.
- The bucket test. Floating or sinking in water is a rough clue, not proof, and it does not show how a fruit was ripened.
Because none of these settles it, the more useful checks are on the seller: a licence number, a GI authorisation number you can verify, a stated ripening method, and a way to report a problem. We ask that damage be reported within 24 hours of delivery. Our guide to identifying authentic Hapus lists more.
Ratnagiri and Devgad Alphonso
Ratnagiri is a district and Devgad is a taluka in Sindhudurg district. Both lie on the Konkan coast, and both grow the same variety. We source from 48 villages across the belt, harvest by hand with a zela pole fitted with a catching net, and harvest all our Alphonso at Brahma Muhurta, the pre-dawn hour. We do not rank one origin above the other. Pick by grade, size and price. See Ratnagiri Hapus and Devgad mangoes.

People also ask
How can I identify an authentic Alphonso mango?
Check four things: the variety, the named origin, the ripening method and the seller. Ask for a GI authorisation number and an FSSAI licence number. Smell, colour and the bucket test are rough clues, not proof, so rely on the seller's answers and credentials rather than appearance alone.
What does Ratna Alphonso mean?
Ratna Alphonso is a shorthand for Ratnagiri Alphonso, the Alphonso mango grown in Ratnagiri district on the Konkan coast. The fruit is also called Hapus or Hafoos. Ratnagiri and Devgad Alphonso are the same variety, and we sell both by the dozen.
Is GI-tagged Alphonso the same as authentic Alphonso?
A GI tag is evidence of origin and the right to use the name, so it is a strong part of authenticity. It does not describe the ripening method. Ask the seller for the GI authorisation number as well as how the fruit was ripened and which licence the seller holds.
Can I tell if a mango is carbide-ripened at home?
Not reliably. Uniform bright yellow colour or a weak smell are only rough clues, and the water test is a rough clue, not proof. Selling fruit ripened with carbide gas is prohibited in India. The better step is to ask the seller how the fruit was ripened.
