Hi all, first post here. I'm to the point of asking for some help. I bought a Breville Dual Boiler (BES920XL) and a Breville Smart Grinder Pro. I also picked up a scale and a 30lb tamper. I started off using Illy beans and everything turned out great. Then I switched to lavazza super crema and everything was still great. Then, out of nowhere, eveything hit the fan. I could no longer make an espresso that didn't make me gag. My wife and I can't really tell the difference between sour/bitter so not sure how to describe the flavor but it's horrible. Almost makes you want to throw up. I've tried everything I can think of. Tried changing the Lavazza beans back to Illy, didn't help. Tried playing around with different grind sizes. Didn't help. Tried playing with dosing to do 16-18g didn't help. Tried "overdosing" and trimming with the Razor tool. Didn't help. Even bought a naked PF, which didn't help.
I ended up buying some 49th Parallel Espresso beans after reading a good review and just got them yesterday so I attempted it again. Still disgusting. I tried a few different things with those beans and still no go. So that's when I decided to document the whole process and ask for help. Maybe there is something I'm missing or doing wrong. I love drinking an espresso and I love making espresso based drinks so I've invested in all of the equipment that got great reviews and I'm more than willing to spend the money where it's needed so I can get an amazing shot.
Weighing a dish before weighing the beans
How it came out of the grinder
Weighing the grinds to see how much came out
Doing the weiss distribution technique in the bowl to break up clumps
Breville shower head, no plugged holes
Grounds in PF, pre-tamp
puck, bit sloppy but comes out in one piece. i've tried changing things around until I get a dryer puck and it still tastes bad.
shower head has some grounds. changed things arounds until no grounds on head and still tastes bad.
