How to Store Your Vanilla Pods

A vanilla bean keeps best in an airtight container, away from light, at room temperature, and not in the refrigerator. These rules fit in a few lines; the rest of this article explains why, and what to do if a bean dries out, crystallises or goes mouldy.

The container and temperature guidelines come from spice and vanilla professionals (see the sources). They are rules of thumb, not guarantees.

What are the three enemies of a vanilla bean?

Light, air and excessive moisture are the main causes of drying out and loss of aroma. A bean exposed to too much air becomes brittle; a bean shut in with too much moisture risks going mouldy.

The whole point is finding the balance: protecting the bean from air and light without trapping it in moisture.

Which container should you choose to store a vanilla bean?

Épices Rœllinger recommends a glass or metal tube or jar that closes tightly. A zip bag with the air pressed out, or vacuum packing, are presented as workable alternatives.

Pick a container sized to your beans: one that is too big leaves too much air around them. A cork stopper is discouraged, because cork lets moisture through. Wrapping each bean in baking parchment limits air contact further, though it is not essential.

The same professional advises opening the container once a month for about ten minutes to let excess moisture escape.

Where should you keep your vanilla beans?

Choose a dry, dark place, away from any heat source, where the temperature stays steady. Épices Rœllinger gives a guideline of between 15 and 20 °C.

A kitchen cupboard will do, as long as it is not next to the oven or above the hob.

Fridge or freezer: why are they discouraged?

The refrigerator is discouraged: the temperature is far from ideal and ambient humidity raises the risk of mould. Cold can also cause crystals to appear on the bean (see below).

The freezer is also discouraged by Épices Rœllinger, who points to a risk of heavy drying and loss of aroma. We follow that cautious advice.

How do you store a bean that has already been used?

A bean that has already been infused, for example in a vanilla rice pudding, is not finished. Rinse it, let it dry completely (a bean that is still damp can go mouldy in the sugar), then slip it into a jar of sugar to make vanilla sugar.

Galand Vanille suggests one to two empty, dried beans per 500 g of sugar, left for two to three weeks and shaken from time to time. Valrhona also suggests drying spent beans in the oven at 90 °C, then grinding them into powder. For more reuse ideas, read how to use a vanilla bean.

My bean is dry: how do you rehydrate it?

A dry bean can still be used, even if it has lost some of its aromatic qualities. Épices Rœllinger suggests infusing it for 10 to 15 minutes in hot, barely simmering milk, or soaking it for 24 hours in room-temperature water.

Once the bean is supple again, split it and use it as usual. If it stays rigid or scentless, it is better to pick another one.

Crystals or mould: how can you tell the difference?

Crystals generally appear when a bean has been kept below 15 °C, for example in a refrigerator. According to Épices Rœllinger, they are not mould: they are crystals that form on the surface because of the cold. They usually disappear once the bean returns to room temperature.

If the deposit persists, or looks like a white or greenish fuzz, or comes with a musty smell, it may be mould. A mouldy bean should not be used: discard it. If in doubt, do not use it.

How long does a vanilla bean keep?

We do not promise any duration. According to Épices Rœllinger, a bean gradually loses its suppleness and fragrance as it dries over time.

To judge a bean, trust your senses: it should be supple, glossy and fragrant. A rigid bean, with no scent, or showing mould, should be discarded. To learn where your beans come from, read our guide to Taha'a vanilla.

If you cook regularly without wanting to stockpile, a small format such as L'Écrin (five beans) saves you from keeping beans for too long. And if you give beans as a gift, pass these tips on: see vanilla beans as a gift.

Can you store a vanilla bean in the fridge?

Better not. Cold and moisture encourage condensation, crystals and mould. A dark cupboard at a steady temperature is preferable.

Can you freeze a vanilla bean?

Épices Rœllinger advises against it: the bean risks drying out heavily and losing its aromas. We recommend not doing it.

What should you do with a bean that has dried out?

Rehydrate it, ten to fifteen minutes in hot milk or twenty-four hours in room-temperature water (Épices Rœllinger's guidelines), then use it in an infusion.

How do you know whether a bean is still good?

Look, touch, smell: a bean in good condition is supple, glossy and fragrant. A rigid or scentless bean has lost quality; a mouldy bean should be discarded.
