At the risk of being an outcast...
...I love froo-froo flavored coffee, like blueberry and pumpkin spice and coconut. Lots of Sweet & Low and the richest creamer available.
I just fill the pot between 6 and 9 cups and fill the reusable filter to 2/3 to 3/4 full. It's not really a science for me. It's just gotta be strong enough.
I don't have an issue with black, except that it's always way too hot to drink right away. Coffee's coffee, and I'll drink it however I can get it.
