This is primarily personal preference; and keep in mind that coffee can vary in flavor just by sitting after brewing for a long time, or if you add sugar, creamer, flavorings, etc. to the coffee.
My personal opinion is to rate Starbucks , Peets, Tim Horton, and dunkin donuts as my #1, 2, 3, and 4 picks, for best coffee of the choices presented.
Peet’s coffee is really good. If we were in Seattle or Hawaii, all bets are off – Seattle has awesome coffee all over the place, and Kona coffee – especially fresh made while visiting Hawaii, is exceptional.
All of these coffee’s can be brewed at home too – they sell their beans, and you can get a burr type grinder to grind them just before you brew, making a superb cup of coffee. I even grind beans that go into my Keurig single cup machine, using a special, reusable K cup (links to Amazon site). (Please don’t hate on me for using a Keurig – it’s convenient and gives me lots of choices when brewing just one cup). Besides, I do recycle them (link to my recycling prototype).
I enjoy a good cup of coffee. Disclaimer: I do own some Starbucks stock.
