How to store specialty coffee: a practical guide to not waste even a gram

Why does coffee go bad?

Coffee is a living product. After roasting, the beans begin to release CO2 (degassing) and progressively oxidize. The four main enemies are: oxygen, humidity, light, and heat. Just a few days of improper exposure can compromise the aromatic profile of a carefully selected specialty coffee. To understand the importance of freshness, also read our beginner's guide to specialty coffee.

The ideal container

Not all containers are created equal. Here's what to look for:

• Airtight – Minimizes contact with oxygen.
• With a one-way valve – Allows CO2 to escape without letting air in. Many specialty packages already have this integrated.
• Opaque – UV light degrades aromas. Avoid transparent containers.
• Non-porous – Glass or stainless steel are preferable to plastic, which absorbs odors over time.

If you buy our whole beans, the original packaging with a valve is already optimal for the first few days. Only transfer to an opaque airtight container if you plan to store them for more than 2 weeks.

Fridge and freezer: yes or no?

This is one of the most heated debates in the world of specialty coffee. The short answer: no to the fridge, yes to the freezer only in specific cases.

• Fridge – Not recommended. Humidity and odors from other foods quickly compromise the coffee. Temperature variations during opening create condensation on the beans.
• Freezer – Acceptable only if you have purchased large quantities and want to store vacuum-sealed portions for months. Once thawed, never refreeze.

For daily use, the best solution is to store coffee at a stable room temperature, away from heat sources like the hob.

How long does whole bean vs ground coffee last?

Grinding drastically accelerates oxidation, increasing the surface area exposed to air.

• Whole beans – Best between 7 and 30 days from roasting. Usable up to 60 days with some aromatic loss.
• Ground – Loses 60% of volatile aromas within 15 minutes of grinding. Ideally, it should be ground at the moment of use.

For this reason, all our coffees — from Ethiopia single origins to Brazil Cerrado Mineiro — are available as whole beans. Investing in a manual or electric grinder is the single most impactful upgrade you can make.

How to tell if coffee has gone bad

Oxidized coffee is not dangerous, but it is wasted. Here are the signs:

• Flat or cardboardy smell – Volatile aromas have evaporated.
• No crema during extraction – Residual CO2 (responsible for crema) has run out.
• Bitter taste and lack of complexity – Only the most stable, often unpleasant, compounds remain.
• Greasy and sticky beans – Oils have migrated to the surface due to excessive oxidation.

Practical tips in summary

1. Buy small quantities often – fresh coffee is always better than stored coffee.
2. Store in an opaque airtight container at a stable room temperature.
3. Grind only the amount you will use immediately.
4. Always check the roast date, not the expiration date.
5. Do not use the fridge. Ever.
