A mango is ripe when it smells sweet near the stalk, gives slightly under gentle thumb pressure and feels heavy for its size. Colour alone is a poor guide, especially for Alphonso, which can stay partly green when fully ripe.
For what is available now, see Ratnagiri Alphonso mango boxes.
Five signs a mango is ripe
No single sign is perfect, so use several together. These are rough clues, not proof, and they work for Alphonso, Kesar and most other varieties. Start with your nose, then your hand, and leave the colour for last.
- Smell at the stalk. Hold the fruit near the stem end and breathe in. A ripe mango smells sweet and fruity. No smell usually means it needs more time. A sharp, sour or alcoholic smell means it has gone too far.
- Gentle squeeze. Cup the fruit in your palm and press lightly with your thumb. A ripe mango yields a little, like a ripe peach. Rock-hard means wait. A mushy or sunken spot means it is overripe.
- Weight. Ripe fruit feels heavy for its size because the flesh is juicy. Compare two mangoes of the same size and pick the heavier one.
- Stalk end. The area around the stem often softens first. A slightly wrinkled, slightly yielding stalk end is normal on a ripe fruit.
- Colour. Use it last. Alphonso can be fully ripe with green patches, and some varieties stay green even when ripe. Skin colour changes with variety, sun and ripening method.
Never press hard with your fingertips. That bruises the flesh and makes the fruit spoil faster. Use the flat of your palm and a light thumb.
Ripeness stages at a glance
| Stage | Smell | Feel | What to do |
|---|---|---|---|
| Unripe | Little or none | Hard, no give | Keep at room temperature, out of the sun, and check daily. |
| Nearly ripe | Faint sweet smell at the stalk | Firm with a slight give | Wait a day, or eat if you like it firm and tangy. |
| Ripe | Clear sweet, fruity smell | Yields to gentle pressure, heavy for size | Eat, or move to the fridge to hold it. |
| Overripe | Sour, fermented or alcoholic | Very soft, sunken or leaking | Discard if it smells off. If only soft, blend it quickly. |
How to ripen a mango at home
Mangoes release ethylene gas themselves as they ripen, and trapping a little of it near the fruit speeds things up. This is why a paper bag helps.
- Paper bag method: put one or two mangoes in a paper bag, fold the top loosely and leave it on the counter. Add a ripe banana or apple to give off more ethylene. Check every day.
- Newspaper wrap: wrap each fruit separately and place them in a cardboard box. This also stops fruit rubbing and bruising.
- Keep away from direct sun and heat. Warm shade is enough. Strong sun can spoil the skin and ripen the fruit unevenly.
- Do not use plastic bags. They trap moisture and can lead to mould.
- Do not refrigerate unripe fruit. Cold stops ripening and can damage the flesh.
For more detail, see our full guides on how to ripen Alphonso mangoes at home and how to ripen mangoes at home. There is also a note on how long it takes for a mango to ripen.
How long does a mango take to ripen?
It depends on how mature the fruit was when picked and on room temperature. Wikipedia gives about 15 days from harvest to ripening for Alphonso, which is a rough guide only. Once it is with you and already starting to soften, it usually needs only a few more days at room temperature. Fruit that arrives hard may need longer. Warmer rooms are faster and cooler rooms slower.
The honest answer is to check it daily. Do not rely on a fixed number of days, because two mangoes from one box can ripen days apart.
How we ripen our Alphonso
Mature fruit is harvested pre-dawn at Brahma Muhurta by hand, using a zela pole fitted with a catching net. We source Alphonso from 48 villages across the Ratnagiri and Devgad belt on the Konkan coast. After harvest, the fruit is laid on hay beds to ripen on its own. We do not use carbide. Our Alphonso mangoes are ripened naturally on hay beds. The table below compares the two methods. Selling fruit ripened with calcium carbide (acetylene) gas is prohibited under Regulation 2.3.5 of the Food Safety and Standards (Prohibition and Restrictions on Sales) Regulations, 2011.
Hay-ripened vs carbide-ripened mangoes: what differs
| 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. |
| Taste and health note | Sweet with a little acidity, soft flesh. | 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. |
No home test, including the water or bucket test, proves how a mango was ripened. Ask any seller how the fruit was ripened.
Is a ripe mango acidic or alkaline?
A ripe mango is on the acidic side of neutral, like most fruit. Raw mango is more sour because it holds more fruit acids and less sugar. As the fruit ripens, the acids fall and the sugars rise, so ripe mango tastes sweeter and less sharp. You may see claims online that mango is alkaline in the body after digestion. That is a contested idea, and we do not rely on it.
If you have acid reflux, diabetes or another condition that affects what you can eat, ask your doctor or dietitian how much mango suits you. Ripe mango is naturally sweet, so portions matter for some people.
Storing ripe and cut mango
- Ripe, whole fruit: move it to the fridge to slow further ripening, and eat it within a few days. Let it come back toward room temperature before eating for the best taste.
- Cut fruit: store it in a covered container in the fridge and eat it within a day or two.
- Pulp: freeze it in small portions for aamras or smoothies. Our freezer storage guide explains how.
- More tips: read our guide to storing mangoes and the notes on selection, storage and ripening of Ratnagiri Hapus.
If a box from us arrives damaged, report it within 24 hours of delivery by writing to support@alphonsomango.in or calling 8369048029.
When a mango is past its best
Throw the fruit away if it smells fermented or alcoholic, leaks liquid, shows mould or has large black, sunken areas. A mango that is only very soft, with a normal sweet smell, can still be blended into a lassi, smoothie or aamras. If you are unsure and the fruit smells off, do not taste it.
Order Alphonso in season
Alphonso is harvested about February to June, with the best supply from March to May. The 2027 season opens on 1 February 2027. Outside the season we do not sell fresh Alphonso, but our Alphonso pulp tins (850 g and 3.1 kg) is available all year, from Rs 590. In season, you can order GI-tagged Ratnagiri Alphonso or GI-tagged Devgad Alphonso, with prices from Rs 1,849 per dozen. A dozen weighs roughly 1.8 to 3.3 kg depending on grade. Our fruit carries the GI Authorised User certificate AU/5974/GI/139/260 (GI No. 139). Details are on our Brand Facts page.

How do you tell if a mango is ripe?
Smell the stalk end for a sweet, fruity scent, then cup the fruit and press gently with your thumb. A ripe mango yields slightly and feels heavy for its size. Check colour last, because Alphonso and some other varieties can be fully ripe with green patches.
How long does a mango take to ripen?
It depends on how mature the fruit was at harvest and on room temperature. Alphonso takes about 15 days from harvest to ripening, according to Wikipedia. Once fruit is firm and starting to soften at home, it often needs a few more days. Check it daily instead of counting.
Is a ripe mango acidic or alkaline?
A ripe mango is on the acidic side of neutral, as most fruit is. The acids fall and the sugars rise as the fruit ripens, so it tastes sweeter than raw mango. If you have reflux or another condition, ask your doctor how much mango suits you.
Can you put a ripe mango in the fridge?
Yes. Once a mango is ripe, the fridge slows further ripening and helps it last a few days longer. Never refrigerate unripe mangoes, because cold stops ripening and can damage the flesh. Let a chilled fruit sit out for a short while before eating for better flavour.
