My home espresso shots taste totally different at 6 AM versus noon
I've been dialing in this same Brazilian bean from Blue Bottle for 2 weeks now, and I swear the same grind setting pulls a bitter 28 second shot in the morning but a sweet 32 second one after lunch. Turns out my kitchen humidity swings about 15% between those times, and that changes how the grounds pack in the basket. Has anyone else tracked their brew times by hour of day, or am I just chasing ghosts with this cheap hygrometer? I'd love to hear if temperature swings mess with anyone else's puck prep.
Tracked mine for a whole month with a cheap temp and humidity gauge and yeah the swing is real. What surprised me was how much the beans themselves change, like I could hear them grind different in the morning versus later on. Are you weighing your dose every single time or going by volume in the basket? Because if it's volume, that humidity difference hits way harder than most people want to admit. Also wondering if you let the machine warm up the same amount both times or if the noon session gets a longer heat soak.
