Ever had those beans that just don’t work?

Hello folks! I am (dreadfully) finishing a bag of Ethiopian Washed Medium-Light roast coffee from a local roaster - Hatch.

The beans in question are called Starlight which are supposed to offer a Floral, Stonefruit, Citrus note.

Now, I don’t know if it’s a taste preference, and I don’t want to insult the roaster, nor is it my intention to do so - but I don’t know if this is just a subpar coffee, poor lot, or my technique.

I’ve tried every permutation I can think of a different pours: 4:6, 5 pour, Lance Hendricks method, different t bloom times.

Tried a Kasuya V60 (slower drawdown), regular V60, Origami (basically a V60) and different ratios between 15:1 and 17:1.

Also tried Hario Switch with Hoffmans recipe.

Tried different grinds on my ZP6 and K Ultra, different water temperatures from 94 to 96, and now…. Well, out of ideas.

Drawdowns between 2:45 and 3:45

The coffee just does not taste appealing or good - it’s hollow, has an unpleasant sour note that’s masquerading behind some hollow flavours, and - well, that’s about it.

Also tried TWW in half and full strength.

I get consistent cups, just very unpleasant flavours.

Does anyone have any pointers?

Thanks!
