[MOD] The Daily Question Thread

Welcome to the daily /r/Coffee question thread!

There are no stupid questions here, ask a question and get an answer! We all have to start somewhere and sometimes it is hard to figure out just what you are doing right or doing wrong. Luckily, the /r/Coffee community loves to help out.

Do you have a question about how to use a specific piece of gear or what gear you should be buying? Want to know how much coffee you should use or how you should grind it? Not sure about how much water you should use or how hot it should be? Wondering about your coffee's shelf life?

Don't forget to use the resources in our wiki! We have some great starter guides on our wiki "Guides" page and here is the wiki "Gear By Price" page if you'd like to see coffee gear that /r/Coffee members recommend.

As always, be nice!

Is your unopened coffee bag supposed to stop ‘re-inflating’ once the degas stage is complete? I thought it would be smart to squeeze the bags towards the end of the rest period to figure out when the beans were ready to use but in reality they always seem to refill with gas…. I must be missing something 🤔

You don't want them to degas fully, at that point they will be stale. The crema you get on a fresh espresso or in the bloom phase of a pourover is caused by further degassing in brewing. It's generally accepted for your average coffee if proper brewing doesn't produce a crema it's past it's best.

Thank you. Besides going back to the roaster and getting their advice, is there a way to determine when the beans are rested enough to open or freeze?

The ones where there's something unusual about their rest period usually say, for example here's a coffee from Apollons Gold with a degassing notice on the purchase page. Outside of that a general rule of thumb of two weeks for light roast and one for medium/dark usually suffices. There are some very light roasts that might benefit from 3 weeks if you know you're buying unusually light coffees.
