I finally dialed in my espresso after a week of sour shots

Turns out my machine's water temp was way too low, so I bumped it up to 203 degrees. Anyone else have a go-to fix for under-extracted beans?

Wait, so how do you tell the difference between sour from low temp and sour from beans that are too fresh? Is it just a taste thing or are there other signs?

Actually, sour shots can be a sign of beans that are just too fresh, not under-extraction.
