How to properly store coffee during hot summer days

Summer brings high temperatures that can significantly affect the quality of your favorite coffee. If you want to enjoy its full aroma and flavor, it’s important to know how to store coffee properly during hot summer days. In this article, we’ll share practical tips and tricks to help you preserve the freshness and taste of your coffee even during heatwaves.

Why is proper coffee storage important?

Coffee is a living product that is sensitive to light, moisture, air, and temperature. In summer, high temperatures can accelerate oxidation and aroma degradation, leading to a loss of flavor and freshness. Improper storage can also cause the coffee to absorb unwanted odors and moisture, which will ruin its quality.

5 tips for storing coffee during summer

Store coffee in a cool, dark place
Avoid direct sunlight and areas with high temperatures, such as windows, stoves, or near ovens. Ideally, keep your coffee in a cupboard or pantry where the temperature is stable.
Use airtight containers
Air is the main enemy of coffee freshness. Transfer your coffee into an airtight container with a sealable lid to prevent air and moisture from getting in.
Don’t buy large quantities at once
In summer, it’s better to buy coffee in smaller batches that you can consume quickly to minimize the time it’s exposed to air.

Avoid using the fridge or freezer (except in specific cases)
While it might seem like a good idea, fridges often contain mixed food odors and create condensation, both of which can affect coffee quality. The only exception is storing a large quantity of coffee for a long period—then it should be carefully sealed in vacuum packaging.
Keep coffee in its original packaging
If the packaging is high-quality and has a CO₂ release valve, it may be best to leave the coffee in it, as long as it’s properly sealed. The valve allows gases to escape without letting air in.

How to store ground coffee during summer

Ground coffee is much more sensitive to oxidation than whole beans. Store it in an airtight container and consume it as soon as possible—ideally within 1–2 weeks after grinding. For maximum freshness, consider grinding your coffee right before brewing.

Bonus tip: Use quality brewing tools

The quality of your brew depends not only on the freshness of your coffee but also on the right equipment. Invest in a good grinder (for example, the Timemore Millab E01) and storage containers that help preserve all the aromas.
