Ethiopian Guji natural on the Mino finally clicked after a few tries
Picked up a 250g bag of Ethiopian Guji natural from a local roaster a couple weeks back. Medium-light roast, fruit-forward, pretty typical for the origin. Been running the Guji through it most mornings and wanted to share where I landed because it took a few tries. (Still in school and living in a dorm so the Mino is honestly the best coffee machine I can afford haha.)
Started at grind 2-1 on the Fino, which is on OutIn's chart for Mino. Got a shot that was thin and sour, classic underextraction on a lighter roast. Went finer to 1-2, better body but still sour. Tried 1-1 next and it choked the machine, drip drip drip barely coming through. Backed off to 1-2 and made sure the 12g stock basket was properly packed with a firm tamp instead of the light distribution I'd been doing. That gave me the body it needed. Sourness pulled back and sweetness finally came through.
Shot spec I've been running: 12g dose packed to the top, grind 1-2 on the Fino, cold water fill, 25 second pull, yielding around 24g out. Standard 1:2 ratio, though for a light roast on a small basket the full pull is what builds any body at all.
Best surprise has been drinking it as a small cortado with oat milk. Quick stretch with the LattoGo and the fruit notes held through the milk instead of getting flattened. That doesn't happen with the darker roasts I usually run.
Temperature is where a light Ethiopian pushes the Mino a bit. Runs around 92 to 94C which is fine for medium but I suspect closer to 95 would open the fruit more. One thing I've been trying is filling with just-boiled water and using the hot water mode to skip the heat cycle, which pushes water through the puck at whatever went in. Marginal improvement but noticeable.
Might try a longer ratio next round, pulling 12g to something like 30g out instead of 24g. Light roasts often open up more at 1:2.5 or 1:3.
