Got more beans than you can brew this fortnight? Freeze them the right way and you can keep the flavour for months. Here is what we do at Central Coast Coffee, what we use at home, and when to freeze.
How coffee ages
Air, moisture, light, and warmth all speed up staling. Every time you open a bag, fresh air hits the beans again. That does more damage than most people expect.
Fresh off the roast is not always best. Beans need time to degas. Lighter roasts need longer. Every coffee on our site has a peak flavour chart on the product page. We explain it on Coffee Lingo too.
This week: keep the bag sealed
Working through a bag over the next week or two? Keep it in the original packaging, press the seal closed after each use, and store it somewhere cool, dry, and out of direct sunlight.
Want a step up on the bench? Use a container that pushes air out instead of trapping it inside.
Airscape for open bags
We use Airscape canisters in the roastery and at home. Push the inner plunger down and it forces air out.

Browse the full Airscape range. For vacuum sealing, see our Fellow Atmos canisters (0.4L, 0.7L, and 1.2L).
Freezing: Weber Bean Cellar tubes
For long-term storage we single-dose into Weber tubes and freeze. Portion once, thaw one dose at a time, and you are not opening the same bag in humid air every morning.
Tall or Shorty? Personal preference. Both are freezer-safe, stack neatly, and use Weber’s one-way valve cap so coffee can still degas after sealing.
Shorty |
Tall polymer |
- Weber Bean Cellar Shorty Polymer: single tubes, frosted or carbon
- Weber Workshops Bean Cellars (Polymer): single tall tubes
- 12-pack with caddy and funnel: starter kit for tall cellars
- Glass cellars: glass option with teak caddy
Racks, bases, and filling tubes
Once you have a drawer of doses, a rack keeps things tidy. We 3D print both options in-house:
Shorty rack |
Tall cellar base |
Filling dozens of tubes is much faster with our 30g dosing scoop. It sits flat on scales or the bench and pours cleanly into both tall and Shorty cellars.
Portioning at scale? The automatic cellar bean doser weighs straight into tubes for you.
When to freeze
Do not freeze straight off the roast while the coffee is still degassing hard. Wait until it is near peak flavour, then freeze.
- Espresso and medium roasts: often peak around days 4 to 15
- Light and Nordic filter roasts: often need two to four weeks; some Signature Series lots peak around day 28 to 35
Check the roast date on your bag against the peak flavour chart on that coffee’s product page. If it already tastes perfect and you will finish the bag within a fortnight, you may not need to freeze at all.
We also freeze select lots at peak here at the roastery. Look for Frozen at peak flavour roast dates on the product page.
How to freeze at home
- Rest the coffee until it is near peak (use the product-page chart).
- Weigh doses into freezer-safe tubes. Tall or Shorty, your call.
- Seal, label with coffee name and roast date, and freeze flat.
- Take one dose out, let it come fully to room temperature, then open, grind, and brew.
Fridge or freezer?
Room temp in a sealed bag or Airscape is fine for coffee you are actively brewing.
Fridge: only for a few days in a truly airtight container. Condensation every time you open the door is the risk.
Freezer: best for long-term storage when coffee is portioned, sealed, and thawed before you open the tube.
TL;DR
Bag or Airscape for this week. Weber tubes (tall or Shorty) for the freezer. Freeze at peak, not on day one. Thaw one dose to room temp before opening.
