For regular coffee, testers used a machine to analyze just how much caffeine each brand contains. Turns out, some had almost four times as much as other coffees. Two boutique coffees - Caribou and Bucks County - had the most caffeine.
To check for taste, Consumer Reports' experts spent weeks brewing, smelling and sipping coffee to find the best. It turns out that buying 100 percent Colombian doesn't guarantee you'll get great taste.
For example, the 100 percent Colombian from Folgers Coffee House Series, the medium dark roast, prompted Ellen Klosz from Consumer Reports to describe it as tasting "like a popsicle stick and cardboard."
Buying pricier coffee doesn't always guarantee quality, either.
"Our tasters found some boutique coffees like Starbucks and Peet's tasted burnt and bitter," said Klosz.
Testers did find a very good coffee that was among the least expensive: it's the Eight O'Clock Coffee 100 Percent Colombian.
"It was even good enough to drink black," said Klosz.
At $6 dollars per pound, the money you can save may make a cup taste even better.
