The creamers and syrups are very weird. Some people here are passionate about them too. It’s always a mixed bag when someone says they’re picky about their coffee.
My go-to is a big pour over, maybe 15g of coffee and 500mL of water. Of course, being American, I measure everything with plastic spoons from McDonalds instead of a scale. I like espresso too, but I’m not big on lattes. Generally no cream, sugar, or anything added.
On the other end of the spectrum is diner coffee. Usually strong but stale. It’s not my favorite but it has a special place in my heart.
If you ever do meet an American coffee snob ask them what they like. We have a whole variety of them.
