In my post summarizing Coffee Review’s look at supermarket coffees, I mentioned that Wal-Mart’s coffee deserved special attention.I was unable to find out exactly where Wal-Mart sources its “Great Value 100% Arabica” but I can tell you where it sources its Sam’s Club’s Member’s Mark: Café Bom Dia, a huge Brazilian coffee … Also see scores for competitive products In the most noteworthy results of the blind taste tests, Walmart’s coffee… And no, the taste test wasn’t organized by Walmart. Walmart has collected 522 reviews with an average score of 2.52. Read consumer reviews to see why people rate Master Chef (Walmart) Coffee 3.8 out of 5. Original review: Aug. 3, 2020. From blends to Colombian, Kenyan to Ethiopian, your caffeine cravings can be satisfied. It was the taste testers at Consumer Reports drinking and comparing all the home-brewed cups of Joe available to consumers. This is the lowest cost coffeemaker at Walmart, or anywhere, so of course, my expectations are not higher than that. There are 192 customers that Walmart, rating them as bad. Brew up the best coffee.
