Definite channeling but can't figure out my issue... [Gaggia Pro Classic 2019 / Eureka Mignon]
I just cannot figure out where I'm going wrong here. Extraction was 15g in with 30g out in around 23 seconds.
Using a Gaggia Pro Classic 2019 with 9 bar OPV mod, 15g VST Competition basket. Coffee is a Light Roast blend from Grindhouse, roasted 2 weeks ago - which I typically find to be the sweet spot.
There's a dryness to the shot, but also some bitter and sour notes - which indicates it's channeling as some sections over and under extract. I've tried making the grind finer and coarser and I'm just.... ugh
It start out fine it looks, maybe a tad quick even, but I can't seem to get rid of the channeling completely.
First clip is an excerpt from the extraction just to show the channeling, then the full extraction, the prep before the extraction to see if I'm doing something wrong here.
I cannot figure this one out and it's driving me nuts!
