How Long Should Coffee Rest? Rest Times for Every Roast

September 28, 2025

Discover why freshly roasted coffee needs to rest before brewing. Learn optimal degassing times for dark, medium, and light roasts, plus storage tips for perfect flavour.

Beans resting in a cupboard

So you just received your freshly roasted coffee from us. The roast date on the bag is literally yesterday. You open it up, take a deep breath of that incredible aroma, and you're faced with a choice: brew it right now or wait a bit?

Here's the cool thing about getting coffee this fresh: you're in control. You get to decide when it tastes best for your specific brewing method and taste preferences. Some of our customers love brewing immediately and tasting how the coffee evolves day by day. Others have found their personal sweet spot is waiting a few days or even a week.

Let me share what I've learned about coffee resting, so you can make the most of your beans and find your perfect timing.

The Science of What's Happening in Your Fresh Coffee

When we roast your coffee (at temperatures over 200°C), we're creating all sorts of complex chemical reactions. Sugars caramelize, moisture evaporates, and gases form inside the beans. The main gas? Carbon dioxide, which makes up about 1% of the roasted bean's weight.

This CO2 starts escaping as soon as we finish roasting. In fact, 40-70% of it releases within the first 24 hours. The rest continues to slowly escape over the following days or weeks. This process is called degassing, and understanding it helps you optimize your brew.

Think of it like this: your coffee is alive and changing. Every day brings subtle differences in how it brews and tastes. Having it super fresh means you get to experience this entire journey.

Why Resting Can Enhance Your Coffee Experience

CO2 plays an interesting role in coffee. It creates that beautiful crema on espresso and that satisfying bloom when you make pour-over. It's also part of what makes fresh coffee smell so incredible when you first open the bag.

But CO2 can also affect extraction. When there's a lot of it:

  • It can create a barrier between water and coffee particles
  • Espresso might pull a bit fast or create extra foam
  • You might notice bigger bubbles during your pour-over bloom
  • The flavor profile might lean more acidic and bright

As CO2 levels decrease over time:

  • Extraction becomes more consistent
  • Flavors often become more integrated and balanced
  • Sweetness tends to develop and become more pronounced
  • The acidity mellows into the overall flavor profile

Neither fresh nor rested is inherently better. They're just different expressions of the same coffee.

Finding Your Personal Sweet Spot

Every coffee is unique, and so is every coffee drinker. Here's a guide to help you explore when your coffee might taste best for you:

Dark Roasts

Peak window: 1-5 days

Our dark roasts are actually quite forgiving. The extended roasting makes them more porous, so they degas quickly. Many customers love them right away, though some prefer waiting 24-48 hours. Try it fresh, then try it again in a couple days. See which you prefer.

Medium Roasts

Peak window: 5-14 days

These are wonderfully versatile. Some of our regulars swear by day 3, others won't touch them until day 7. The beauty is that medium roasts have a long peak window, so you've got time to experiment and find your preference.

Light Roasts

Peak window: 7-21 days

Light roasts are where patience can really pay off. Their denser structure means slower degassing and longer flavor development. But here's a secret: some people actually love the bright, zingy character of super fresh light roasts. If you're curious, try some on day 2, then again on day 10. The transformation is fascinating.

Nordic Style Ultra-Lights

Peak window: 14-60 days

These are the marathon runners of coffee. They can keep developing for weeks or even months. Getting them fresh means you can taste them at every stage of their evolution, something you'd miss if they were already weeks old when you got them.

Brewing Methods: Working With Fresh Coffee

One of the best things about having super fresh coffee is that you can adjust your brewing to match its current state. Here's how:

For Espresso

Fresh coffee pulls differently, often with more crema and slightly faster flow. You might want to:

  • Grind a touch finer to slow down the shot
  • Enjoy the extra crema (some cafes charge extra for this!)
  • Note how the flavor changes daily as you dial it in
  • Most find their ideal window is 5-14 days, but experiment!

For Pour Over

Fresh coffee creates an impressive bloom, which is actually pretty fun to watch:

  • Extend your bloom time to 45 seconds with very fresh coffee
  • Enjoy watching those CO2 bubbles dance
  • The brightness of fresh coffee can be amazing with fruity African coffees
  • Many love pour-over anywhere from day 3 onward

For French Press

This is the most forgiving method for fresh coffee:

  • The long steeping time works great even with day-old coffee
  • No channeling issues to worry about
  • Some customers specifically request their French press coffee super fresh
  • Works well at literally any age

Your Coffee Journey Starts Now

Having coffee delivered fresh from the roaster means you're getting the full experience. You can:

  1. Track the evolution: Try a cup every few days and note how it changes. It's like watching a photo develop.
  2. Find your preference: Maybe you love that bright, vibrant day 3 cup. Or perhaps you're a day 10 person who loves integrated flavors. There's no wrong answer.
  3. Match to your mood: Feeling adventurous? Try it super fresh. Want something mellow? Wait a week. You have options!
  4. Stock rotation: Order weekly and you'll always have coffee at different stages. Last week's order might be peaking while this week's is resting.

Storage Tips for Your Fresh Coffee

To get the most from your beans during their journey:

Keep them in our bags with the one-way valve. It lets CO2 escape while keeping oxygen out. Store at room temperature, away from light. If you won't finish a bag within two weeks, you can freeze portions after they've rested to your liking.

Want to test how fresh your coffee is? Put a few beans in a sealed plastic bag overnight. If it puffs up, there's still lots of CO2 releasing. It's a fun experiment!

Making Fresh Coffee Work for You

Sometimes you want coffee NOW and can't wait for it to rest. No problem! Here are some pro tips:

  • Use a slightly coarser grind to help with extraction
  • Lower your water temperature by 5 degrees
  • Embrace the brightness (especially good with fruity coffees)
  • Try cupping to taste the pure flavor without brewing variables

The Bottom Line: It's Your Coffee

Getting freshly roasted coffee isn't about following strict rules. It's about having the freedom to experience your coffee exactly how you like it. Some of our customers specifically request the freshest possible roasts because they love that bright, vibrant character. Others order ahead so they have perfectly rested coffee when they need it.

The "best" day to drink your coffee is the day it tastes best to you. Having it fresh just means you get to make that choice yourself.

Think of it like getting farm-fresh produce versus grocery store vegetables. Sure, you might let those tomatoes ripen on your counter for a few days, but having them fresh means you control when and how you enjoy them. Same with coffee.

Every time you brew, you're learning something about your coffee and your preferences. That first cup on day 2 might be brilliantly bright. Day 7 might reveal chocolate notes you didn't notice before. Day 14 might be when everything comes together perfectly for your palate. Or you might love it most on day 3 and think day 14 is boring. Both are valid!

Your Fresh Coffee Adventure

Remember, coffee is supposed to be enjoyable, not stressful. Having super fresh coffee gives you options, not obligations. Experiment, have fun, and find what works for you.

Some final thoughts:

  • There's no "wrong" time to drink your coffee
  • Fresh coffee shows you the full spectrum of flavors over time
  • Your perfect day might be different from someone else's
  • Different coffees peak at different times
  • Your brewing method affects the ideal rest time
  • Trust your taste buds over any guide
