If you know a thing or two about coffee, you might find the other brands recommended here too lowbrow. Kloo's coffee concentrates are curated by such tasters, also known as “Q Graders,” and I couldn't stop saying “Wow” out loud while I tested the brand's offerings. I am not a coffee snob—I do test pod coffee makers, after all—and even I could taste the difference here. This is not necessarily the most economical of options—one $33 bottle of concentrate makes 12 cups of coffee. But if you're a true coffee lover, this single-origin stuff is up your alley.
