Good to see tradiionalists in here! I too am a medium/dark roast fan.
I’ve tried to enjoy lighter coffee and so much of it ends up going stale or sitting in the freezer as I struggle through it. I get the odd epic shot as espesso, but it’s rare. On the lighter roast shots I pull I always taste them first, then decide whether they need milk to become palatable, or just need a bit of water as a short black.
I tend to cycle between roasters now and I’ve settled on the following which I really enjoy:
Rave mocha Java - amazing with milk as a flat white or cortado
Rave Chatswood - ace for black and pretty good white
Coffee compass jampit hit and Malabar hit are both great. I usually buy their taster packs, think it’s 3 × 500g bags, and I’ll throw in a bag of sweet bourbon or Brighton lanes.
When in a bind I’ll buy Clifton coffee from my local (very good) coffee shop Fawns in Clevedon, or go to Wyvern coffee in Cheddar (shop outlet for Wogan coffee in Bristol)
Edit: I didn’t answer the question, I’d say Chatswood for being such a good all rounder.
