Is your spice grinder a blade grinder? If so you are likely getting a very inconsistent grind. This may affect the taste of the coffee dramatically.
The first recommendation I give to people that want to get into brewing better tasting coffee is to get a burr grinder, even a handheld one will do just fine. With a burr grinder you just get a more consistent grind which helps reduce the fines thereby reducing the bitterness.

I second this, but do get one with a metal burr like a Timemore, and not the oft-recommended Hario Skerton, which has a ceramic burr.
The manual grinding experience with a metal burr grinder is so much better.
