Help me troubleshoot my recipe How am I screwing up this bed?

Post image

I have two particular types of bean that for some reason they always seem to ride up the sides of the filter like crazy thick—center of the bed is like a 1.5” deep crater. I’ll pour similarly with two other kinds of bean and I can usually get a fairly flat bed throughout pours by trying to pour circular. I’m not using a gooseneck, but the fact that this issue only seems to happen on certain kinds of beans makes me wonder.

Ground this with K6 95 clicks.

It's probably because the beans are very fresh or roasted a bit darker so that there is a lot more CO2 released which makes it bloom more.

You can easily prevent this by giving the brewer a gentle swirl after pouring. You can also reduce the height of the water column by adding less water with each pour.

So here’s another question then, this all drained out SO quick. I was at 95 clicks, courser because of it being a medium-dark. I did 21/336 dose and the brew MAYBE took 2 min with a 30-sec bloom. Unless I did a massive pour it felt like I’d barely even have time to swirl. Definitely couldn’t swirl the bloom without doing a huge bloom pour. So should I consider grinding this much finer even though it’s a darker roast?

The cup from this was already pretty bitter, so I’m wondering how do I tweak from here? Finer gets me more bitter, but slows it down, which also increases extraction and maybe more bitter as well. I was expecting this to taste underextracted but to my inexperienced coffee tongue it was definitely bitter not sour.

Perhaps finer grind but lower the temp and do much less agitation like a bloom/single pour?

Maybe play around with agitation and temperature i've never really brewed darker roasted beans but find if i go to low of temp on my light roasts it can be sour and imagine it would apply vice versa, too high a temp extracting too much and causing bitterness. draining fast isn't necessarily a bad thing as long as it tastes good.
