Caribbean Coffee -- not the coffee from the Caribbean but a company that sells all kinds of coffee. They have a kind called "Hair Raiser" coffee, very strong, good flavor. The company is in Santa Barbara, California, but they also have a website. They mostly sell to coffee bars, specialty grocery stores, that sort of thing.
Also, "Smooth and Mellow" from Trader Joe's -- of course TJs is just in the US as far as I know. It's a medium roast, very delicious.
Best place to get coffee? At home, if I make it for you.
