Does the weather affect coffee beans?
After it is roasted, coffee begins to release carbon dioxide gas and oil. Degassing is an important part of roasting and determines how long the coffee will be prime for brewing.
Degassing normally takes between 5-7 days. The coffee degasses faster at higher temperatures and slower when it is colder.
Degassing can take as long as ten days now due to the colder weather.
Remember that it’s not only the temperature but also the humidity level that will affect your skin.
A humid day will cause the coffee to absorb more moisture than a dry one. On a sweltering day, water from an Espresso machine will take longer for the coffee to absorb the moisture.
If you are extracting your espresso shots quickly, they may taste sour or watery, possibly grassy, herb-like, or even bad.
The Solution to
- You can adjust your grind by making it finer or coarser. Keep changing your grind until you reach your ideal extraction time. If you are experiencing a fast extraction, try grinding finer. If your extraction time is too long, make your grind coarser.
- It would be best if you looked for coffee that has been roasted within the last ten days.

Tips to remember:
- When you adjust the grinder, always remove a small amount of coffee. The next shot you take will have a finer grind.
- Make small adjustments to the grinder. Purge out the dose and check again for extraction time. Small adjustments in the grind size can have a significant impact on your extraction time.
- On our bags, we include the roast week and the date that you roasted your coffee. We recommend drinking it within eight weeks of the roast date.
