So I finally dialed in a bag I loved, wrote down my grind setting, felt like a genius. Opened a fresh bag from a different roaster this morning, same 18g dose, same setting, and it gushed out in 14 seconds tasting sharp and sour. Nothing else changed. Is this normal? Do I really have to re-dial from scratch every single bag? This one is a lighter roast if that matters, roasted about five days ago. I ground finer by three clicks on my Encore ESP and it slowed down a bit but still tastes sour. Should I keep grinding finer or bump the temperature? Where do you even start when a new bag fights you like this?
