A new blind taste test from Japan’s respected consumer publication LDK offers a revealing look at chain store coffee beans, with results that challenge brand loyalty. Doutor’s “Mild Blend” earned the highest honor, while global giant Starbucks failed to make the top three, ranking fourth overall.
The expert panel judged five popular beans on Taste (balance of acidity, bitterness, and sweetness), Aroma, and Repeat Rate (overall value and repurchase appeal). Only Doutor achieved the highest Grade A rating. Sourced from a blend of Brazilian and Colombian beans, it was described by the panel as a masterclass in blending, offering a rich body with a remarkably clean finish. Its competitive price point makes it an ideal daily brew for home baristas seeking quality without a premium cost.
Tully’s Coffee “House Blend” secured second place with a Grade B rating. This consistent dark roast from Colombia and Guatemala was praised for its reliable quality. It delivers a bold bitterness with a bright acidity, making it a strong recommendation for those who primarily brew milk-based drinks like lattes and cappuccinos.
The biggest talking point was the performance of Starbucks’ “House Blend (Guatemala)” . Although the brand uses 100% Guatemalan beans, the panel noted major inconsistencies in bean size, which led to uneven extraction and harsh bitterness. The judges strongly recommended this bean strictly for milk-based drinks, finding it unpleasant as a black coffee. UCC’s “Coffee-kan Blend” ranked last, criticized for severe unevenness in roasting which resulted in a distinctly harsh and unbalanced flavor profile.
Expert Tips for Choosing Beans
Beyond the rankings, LDK shared actionable advice for home brewers:
- Judge by Color: Darker beans guarantee a bitter profile; lighter, tan beans indicate higher acidity.
- Check Uniformity: Avoid bags with mixed bean sizes or colors, as this signals poor quality control and leads to bitterness.
- Match Your Method: Medium roasts excel for black coffee. Dark roasts offer the intensity needed to complement milk in lattes.
Proper Storage Is Key
The test emphasizes that freshness depends heavily on storage. Whole beans perform best in an airtight container kept in a cool, dark cupboard. Pre-ground coffee is far more vulnerable to oxidation. Experts advise immediately transferring ground coffee to an airtight freezer bag and storing it in the freezer, not the refrigerator, which risks odor contamination.
Broader Implications for Hong Kong’s Coffee Lovers
For Hong Kong’s growing home-brewing community, this LDK test is a valuable strategic tool. Doutor’s decisive victory underscores a crucial lesson: consistent roasting and smart blending can outperform massive marketing budgets. Paying close attention to bean color, uniformity, and intended brewing style is the key to transforming the daily coffee ritual into a more satisfying, well-informed experience.
