Grinding my beans the night before was ruining my morning brew for months

Last Tuesday I woke up and made my usual pour over coffee, but it tasted flat and kind of stale. I've been grinding my beans the night before to save time in the morning, thinking it wouldn't matter much. Then my buddy who roasts coffee locally stopped by and smelled my grounds, said they were already fading after just 8 hours. He explained that coffee starts losing flavor within 15 minutes of grinding because the oils evaporate. I tried grinding right before brewing the next day and the difference was night and day, way more flavor and aroma. Now I wake up 2 minutes earlier to grind fresh each morning. Has anyone else figured out a quick morning routine that doesn't sacrifice freshness?

honestly the thing nobody talks about is how grinding finer in the morning totally changes your water temp needs too. when you grind it fresh it clumps way less and stays fluffy, so if you pour water the same way you did with stale grounds it'll extract way faster and might come out bitter. took me like two weeks to dial in my new morning routine of a slightly coarser grind with a bit cooler water.

My buddy tried this exact thing and wrecked his morning brew for a week straight. He was convinced his grinder broke until I told him to back off the grind size and drop the water temp by like five degrees. Fixed it completely and now he won't shut up about the difference.
