Degassing is discussed a few times. The most cited answer in Coffee SE is probably this question.
In short:
- Degassing takes up to 2 to 4 days to achieve drinkable coffee. If you really want to shorten this, grind earlier. But you should try yourself for best timing.
- The best flavor is around 1 to 2 weeks. Again, you should follow youyour taste buds based on the beans and the roast degree.
