Keeping Your Chocolate Cool: A Retailer’s Guide to Summer

Summer is good for a lot of things in retail. Chocolate isn’t always one of them.

As the temperature climbs, we get the same question from shops across our network: what’s the best way to protect chocolate in summer? So here’s our guide – built from a few decades of collective chocolate-handling experience – on how to store, present and sell craft chocolate through the warmer months, without losing your stock, your margins or your sanity.

First things first: do not put it in the fridge

We know the instinct. It’s hot, chocolate melts, the fridge is cold – it seems logical. It isn’t.

Chocolate is temperature-sensitive in both directions. Fridges are humid environments, and that moisture is a problem. When chocolate goes from a cold fridge back out into a warm room, condensation forms on the surface. That moisture dissolves some of the sugar in the chocolate, which then recrystallises on the surface as the bar dries out – leaving a dull, greyish, sometimes gritty finish called sugar bloom. It doesn’t affect the taste, but it makes a beautifully tempered bar look like it’s gone off, and most customers will assume exactly that.

Fridges also carry odours. Chocolate is porous and will happily absorb the smell of whatever’s sitting next to it – not what you want when someone’s paying good money for a single-origin bar with delicate tasting notes.

So: no fridge. Ever. Not even “just for a few hours during the heatwave.”

What good storage looks like

Craft chocolate is happiest at 16–20ºC, with humidity kept below 55%. In practice, that means:

• A cool, dry stockroom away from any external walls that catch the afternoon sun
• Away from ovens, heaters, dishwashers or anything else generating warmth 
• Store products in boxes until they hit your shelves. A layer or two of cardboard insulation can really help
• Airflow. A small fan circulating air in a warm stockroom can be the difference between stock holding its temper and stock turning soft

If your stockroom regularly creeps above 25ºC in summer, it’s worth investing in a portable air conditioning unit for the worst weeks. You may also want to consider buying a dehumidifier, if you have a particularly humid storeroom. It’ll pay for itself in the stock you save from damage.

On the shop floor 

This is where most bloom and melt problems actually happen – not in the stockroom, but on display.

• Keep chocolate out of direct sunlight. A shelf that’s shaded in the morning can be a sunbeam by 2pm – track your display through a full day before you trust it
• Move stock away from windows, doorways and anything near a heat source, even briefly, during a heatwave
• If you display near an entrance that gets full sun, consider rotating that space to less heat-sensitive stock during the hottest months and moving chocolate somewhere more sheltered
• Don’t overstock the floor. Smaller amounts on display, replenished more often from a properly stored back stock. This means less time spent by any product in a compromised environment

Talking to customers about it

A softened bar or a touch of bloom isn’t the end of the world, and it’s worth having explanations ready for customers who ask. Sugar bloom is cosmetic – the chocolate is still good to eat, just not at its most photogenic. If a bar has softened in transit or on a hot day, a quick spell in a cool, dry spot (not the fridge!) will usually see it firm back up.

It’s also a good moment to talk about quality. Craft chocolate can be more sensitive to heat than mass-market chocolate that’s loaded with stabilisers – and that’s worth framing as a feature, not a flaw. It’s the same reason it tastes better: less processing, minimal ingredients, more care required. Customers who understand that tend to become more appreciative of specialty chocolate. 

A few extra habits worth building

• Handle chocolate as little as possible in summer – warm hands can quickly impact chocolate
• Check your delivery boxes the moment they arrive, especially on hot days. Get stock into cool storage straightaway, rather than leaving it on a loading dock or in a hot van
• Keep an eye on your own thermometer, not just the forecast – shop floors and stockrooms run hotter than you’d expect
• If in doubt, taste it! It’s worth sacrificing one bar to see whether a shelf-full is still ok to sell

Summer can be a great season for chocolate sales – lighter bars, brighter flavours, plenty of gifting occasions – it just takes a little more care to get it from our warehouse to your customer’s hands in good condition. Our shipments always contain a free mini bar for quality assessment. This is so you can ensure the shipment arrives in perfect condition, without having to open stock to check. 

Consider this the season that separates the shops who really know their product from the ones who just stock it. Perfecting the art of chocolate storage and handling will likely make your customers even more loyal, so it’s worth investing in getting it right.
