Good grief. If you enjoy it then
by definition it is not bad, it is good, even if it didn't cost you an arm and a leg and you got it at the grocery store or the diner. The coffee snobs can just go fuck themselves.
I had two life experiences that beat the culinary snobbery out of me. Many years ago I was a tea-totaller but I decided I wanted to develop a taste for wine (because social pressure) so I started a wine tasting group. It consisted of six couples. We met once a month and rotated hosting duties. About a year in, someone did a blind tasting of cabernets which included a $3 bottle of Barefoot Cab at the low end and a $50 bottle of Silver Oak at the top. (These prices will give you some idea how long ago this was.) Every single one of us rated the Barefoot first or second, and the Silver Oak dead last.
Fast forward a few years and I was looking for a gift to give me parents for their 50th wedding anniversary. They are really in to coffee so I decided to buy them an espresso machine. You can spend a truly ridiculous amount of money on one of those do I decided to do some taste testing to try to find the point of diminishing returns. We ha a $1500 machine at our office and so I decided to use that as a baseline. I enlisted the help of some local coffee snobs for guidance and they instructed me where to get the "proper" beans, which I dutifully sought out. After several hours and many, many attempts, no one was able to produce a cup that any of us considered even remotely drinkable. I ended up getting my parents a Keurig.
On the other hand, whenever I'm in Italy, the coffee there is consistently superior to anything I get anywhere else in the world. I have no idea how they do it, but the Italians obviously know something that the rest of us don't.
