How to Distinguish Good from Bad Black Coffee Beans_What Coffee Beans Are Best for Black Coffee_Which Black Coffee Beans Taste Best

Rethinking Coffee Standards: Beyond Professional Jargon

SCAA or SCAE cupping standards can be found in any book. The processing methods and flavor profiles of the various growing regions are incredibly complex, and the learning curve for the flavor wheel and similar tools is prohibitively steep. Can you imagine asking someone who just wants a simple beverage to grasp the spectral difference between cardamom and cherries? Would they not go mad staring at the chart below? The same goes for the Agtron values that describe roast level. How could ordinary coffee drinkers possibly know what those numbers mean in terms of roast degree?

A Consumer-Centered Approach to Good Coffee

So I am setting professional standards aside to work out what makes a coffee good in the popular sense, from the perspective of someone who is not especially knowledgeable, following a Maslow-like humanistic approach.

First: For the General Masses, a Smooth Coffee

Here I really appreciate Brazil's traditional grading system. Besides defect grading, cupping is divided into several levels:

First Grade: Strictly Soft / Second Grade: Soft / Third Grade: Softish / Fourth Grade: Hard (Unpleasant) / Fifth Grade: Rio (Iodine off-flavor)

The first requirement for good coffee is the absence of offensive defects: monotonous bitterness (the dark-roast schools pay close attention to analyzing bitterness; good bitterness such as bittersweet and aromatic char is what they pursue, while monotonous bitterness should be avoided), astringency (try tasting a handful of dead beans after roasting for a clear demonstration), asphalt flavor (such beans usually get stuck in the roaster and become carbonized), grassy flavors (common in light roasts, accompanied by astringency and numbness) and eye-closing sharp acidity (many half-baked light-roast practitioners produce sharply acidic beans of every kind).

Quality growing regions (not necessarily rare varieties, extremely high altitudes or large bean size), an appropriate roast level and two rounds of hand-sorting (many specialty beans now undergo multiple hand-sortings in their growing regions, so beans at that level can skip raw-bean sorting, with defects basically under 1%) together do a great deal to ensure a smooth cup of coffee.

Second: For More Ambitious Friends, an Interesting Coffee

Enthusiasts in the single-origin world are usually masters of their craft. Beans from different regions and processing methods take you to different worlds: from citrus- and jasmine-scented Yirgacheffe to herbal, woody Mandheling, to the wild enzymatic flavors of natural processing, and so on. In this section I do not recommend drinking many expensive beans; the interesting variety is what truly matters. There are in fact tricks for getting reasonably priced beans. The Japanese roasting master Taguchi Mamoru buys beans that rank in the COE (an authoritative regional award whose winning lots are publicly auctioned online) but sit at the bottom of the rankings: the premium is minimal and the quality is high. I prefer to build good relationships with a few importers who are deeply rooted in the growing regions, with year-round staff sourcing beans and close ties to estates, and then specifically select non-auction lots from COE-winning estates. On average I can pick one excellent value-for-money bean from 5-10 samples.

Third: Beyond Just Flavor, a Cherished Coffee

Take Geisha. Its lemon-tea-like flavor had never appeared before, and when it was first discovered it won numerous awards as a mutant variety with no large-scale cultivation, which is why production is still limited today and prices stay high. But can a completely new flavor profile really justify a price three times that of other coffee beans? The deciding factor is not flavor but rarity, while its consistently high cupping scores actually reflect academic advantages.

Kopi Luwak belongs here too. Do the people who drink it really know what it is? Many of the products circulating in the market, especially those that still look like feces, are made from honey and flour. Traditional Indonesian civets were later replaced with masked palm civets in Yunnan, and then, well, I am getting off topic, so I will not expand further.

How Should One Drink Coffee? Is Black Coffee the Only "Real" Coffee?

Of course not. This is only a plant-based beverage, and coffee's development has been accompanied by countless cultures. There is much to say about espresso, which I will not elaborate on here. Let me discuss some lesser-known aspects. If I were to open a cafe, I would certainly let you experience coffee flavors from various cultural systems rather than force you to drink only black coffee. In both the UK and Australia, for example, I have found shops that provide raw sugar, which has richer flavors than regular white sugar, especially caramel aromas. Below is a photo from MARKET LANE in Melbourne (what is on the table is raw sugar).

Vietnam mainly produces Robusta, and locals add large chunks of ice and condensed milk to bitter but malt-rich Robusta. Many people love it. Japan and Europe both have traditions of adding salt; I have tried it, and it is a very particular flavor that seems to add a unique umami quality (just a little salt is enough; Europe uses mineral salt, Japan uses sea salt). Even more surprising, many customers have told me that black coffee with Wangzai milk is a perfect match.

So in the end, what you need to find is the cup of coffee that makes you happy, whether smooth or unique. Is Robusta bad? It is the most authentic flavor of Vietnamese coffee. (The photo below was taken at FIREST POUR in Melbourne.)

Final Recommendation: Try Different Regional Beans and Only Buy Fresh, Whole Coffee Beans

Freshness is the weakness of the major brands, but today, from Western roasters to the growing ranks of small and micro-roasters, the industry is expanding rapidly and everyone practices flexible, order-based roasting. With such advanced logistics, fresh beans are easy to buy. World-class chains such as Starbucks typically ensure bean quality by roasting in their Seattle roastery and shipping directly from the adjacent airport to locations worldwide; however, by the time beans reach individual stores in regions like China, 3-6 months have passed. Starbucks's daily coffee, for example, is one of the most difficult coffees to swallow that I have ever had (preparation plays a role too; I am not that particular, but it is truly undrinkable, just charred bitterness on top of charred bitterness).

Time is coffee's killer, through three factors above all: 1. Dissipation of aromatic compounds. 2. Maillard reactions at room temperature. 3. Oxidation of oils. The best solution is almost always to buy fresh. Once you have experienced the aroma of coffee within a week of roasting, you basically cannot go back to stale coffee.

There are many more myths to debunk, such as how great peaberries are, Blue Mountain legends and monkeys picking coffee; these belong to the realm of pseudoscience.

FrontStreet Coffee Recommendation

As the largest coffee-producing country, Brazil offers a great many varieties. Brazilian beans carry a moderate acidity, and the balance of sweetness, bitterness and body makes them especially well suited to a medium roast; the roast draws out an inviting nut aroma, with a rich, mellow taste and a faint acidity, and they can be used as a single origin or in a blend.

If you only want a first taste of the Brazilian profile, FrontStreet Coffee's Cerrado semi-washed Red Bourbon is a classic single-origin bean. Cerrado is a well-known local region noted for high-quality coffee, and this lot uses the red bourbon variety common across South America. Roasted medium, it shows the rich aromas of creamy peanut, toast, caramel and hazelnut, with a round body, no sourness and a light bitter finish; it works not only for pour-over but also for moka pot, espresso SOE, siphon and French press. For a rarer character, FrontStreet Coffee's Brazil Queen Estate is grown in Mogiana on fertile red volcanic soil and uses the uncommon yellow bourbon, a natural mutation of red bourbon with a cleaner fruit profile. Brewed as pour-over, moka pot or home espresso, it delivers the sugarcane sweetness found in few other regions, along with fruit and chocolate notes.

The low-acid, balanced taste and approachable price have made Brazilian coffee the first choice for many Italian-style recipes. FrontStreet Coffee's Classic Blend, with its rich crema, the nutty Premium Blend, the well-balanced Black Cocoa and FrontStreet Coffee's Commercial Blend for cafes all contain Brazilian beans, which supply chocolate and cream aromas alongside a soft sweet-sour-bitter balance that helps keep extraction stable.
