This is made on a blend of medium and full city roasted beans, that were made 3 days ago.

It did not taste over extracted (validity of that word aside), so I think I’m literally just seeing off-gassing of co₂ from brewing too fresh beans… Kinda cool.

Does also mean that I should probably learn to order more beans in advance of running out, and perhaps start with roast level that need less time to rest when I get a shipment.

Like the dark roast I got yesterday did not have this issue at all, but makes sense, it’s a dark roast, those apparently need between 1-5 days rest, a medium roast like this more like 5-7.
