Never heard of K-cup ether. I brew my own coffee just by pouring boiling water through a coffee filter that has coffee grounds in it.
I like the French press.. cheap and great coffee..
We used single serving drip coffee plastic filters at home...that way we both get drip coffee... I really like Gelavia coffee, which is very smooth, pre ground and available at supermarkets Wallmart and Target...
In a pinch I drink Starbucks Instant VIA coffee..what they call micro-ground coffee... It’s very good.. I buy the Medium House Blend, because I don’t go for bitter dark coffee beans normally one finds at Starbucks.
