Listen, you can use stale beans, its not a crime. The experience is nicer and easier with fresh beans tho. Dont waste more of this batch trying to dial in. If you drink it and say to yourself "mh, nice cup of coffee" then you're home free 😁 Next bag, try fresher beans. The perfect freshness is around 5 days old (actually too fresh is not great either). I find a week old works great and I want to use them within 3 weeks ish. Thats fine enough for me. Some will religiously go for 2 weeks max, that doesnt work for me logistically. When you get fresh bag of beans, run an extraction with these settings and remember to film it. We'll try to hit good settings within one or two extractions.

Ditch the store, opt for grass-fed meats and wild fish for better nutrients.
