I've recently decided to take a tour of my local roasters' espresso blends. The first two candidates have been:
4th Level Roasters' Espresso Blend. Not terrible, but $18/lb, darker than I prefer, and "robusta forward" in that great body but unfortunate tire-fire flavor sort of way, so I'm glad I only went for an 8oz bag and I don't think I'll get it again.
Nate's Coffee's Nate's Espresso Blend which is $15/lb, and delicious. Balanced, not too dark, good mouthfeel. I'm having to dial a bit, it's pulling a slow shot at my usual starting settings, but even the slow ones were tasty and they're just getting better as I dial the grind out toward a 30ish second shot.
That's what I need to do. I usually get my bags online, but there are some awesome roasters in and around my areas of travel. Nates looks amazing, by the way, and I might just order a couple bags.
Possible extra bonus of local roasters: Nate's (and, AFIK, not uncommon with roasters that run a coffeeshop storefront) has a deal where you get a drip, coldbrew, or $2 credit on a fancier drink when you buy a pound at their brick and mortar. Their relative location makes it a nice early afternoon break for me to go pick up.
