Better Beans: Q Grading, Acidity and Scoring Quality Part One

Several years ago I pulled into a gas station to fill up my car. Those who know me also know I have a penchant, some may say affliction, for vintage British sports cars. The car in question was a British Racing Green Austin-Healey with a vanity plate that read Kaladi. The particular station had an espresso cart operated by a new roaster in town. Upon seeing the plate on the car the young man came out and informed me that "they had better beans."

"How are they better? I queried.

 "They buy better beans," he responded.

 "That's interesting," I replied, "I'm the coffee buyer for Kaladi and I am very particular about coffee quality so I would be interested in how your coffee is better."

"They buy better beans," he said and walked off.

If there is one thing for certain its that every coffee roaster only buys the very best beans. Whether its a narrative of their intrepid globe spanning coffee buyer or some statement of how selective their requirements are, it seems that every coffee roaster would like you to believe that they have the sole purview over quality. But how does one define quality in the coffee industry? It's a worthwhile question, and one open to contention.

For the most part, when a roaster claims they buy the best beans, they are referring to the grade of coffee.  There are a few different ways in which coffee is graded. What they most have in common is that the fewer number of defects, those things that would have an adverse effect on the flavor, the higher the grade. Defects could be things like blackened beans, or sour beans, insect infected beans, or diseased beans, moldy beans or fermented beans, or simply things that are not beans at all, like sticks or stones.

To aid in this removal of defects, it is helpful if the beans share a similar size and density. Bigger beans are equated to healthier beans: greater density in beans is generally equated to higher elevation. When the beans are the same general size and density they flow through the pulping and milling equipment more effectively. Consistency is also necessary when using color sorting devices that separate defective beans using spectronomy. Uniform bean size and density was once more important to roasters as well to ensure a more uniform roast, albeit newer technology in roasters has rendered this less important today.

There is a confusing array of terms to designate a coffee's grade, there being no globally recognized lexicon indicating grade. Some countries use names to designate grade, like Supremo, Extra Fancy, Kohlinoor; others use various letter or number designations, such as Grade 1, AA, SHB, SHG, etc. Additionally, these grades may be different according to the import market: a AA grade may not be the same for the US as for Europe. Generally speaking, though, the higher the grade, the bigger, more uniform density the beans are with the fewest allowable defects.

Grading is done at the export mill, often just before export. As the coffee is bagged it is marked with an identifying number indicating its lot. A lot is a set number of bags that will fit into a shipping container, usually 250, assuming that the bags are around 70 kilos or 150 or so pounds. Of course, different countries will have different size bags as well so this will affect the number of bags in a lot. Lot sizes can also be smaller in cases where a buyer has specified a particular preparation or segregation of a coffee. But it is this number assigned that is ultimately important as this will theoretically follow the coffee to its destination. A coffee bag will have a total of three numbers for identification; the first designates its country of origin, the second the export mill that prepared the coffee, the last the individual lot.

Along the way the coffee will be evaluated by cuppers. Historically this has been the purview of the exporting firm and the importing firm. In practice today, this model is more variegated, but suffice it to say that these cuppers are operating within the "trading" of coffee and so are often called trade cuppers. Trade cupping concerns itself largely with identifying faults and defects in flavor that grading misses. The role of the trade cupper is to act as a gatekeeper for exporter or importer. The last thing these firms want to have happen is for a lot of coffee to be rejected by the buyer because of a fault in the flavor. Best to catch these things before the coffee has left the port. Trade cupping concerns itself with identifying faults such as ferment, mold, past crop, taints from improper preparation or storage, anything that would mar the coffee's flavor and risk rejection by the end buyer, whether that is an importing firm or a roasting firm.

In order to assess coffee for defects the coffee is roasted very light so that certain taints, especially ferment and mold, are more pronounced. At a certain point in roasting, the roast itself can make it more difficult to suss out these faults but they are still there. The fact is, if you are cupping a number of coffees on a cupping table there's no time for subtlety. You want things to slap you in the face. You are not looking for the finer points of the coffee's character, only making sure that you and your firm are protected from a rejected shipment. Trade cupping is not necessarily about determining quality as it is about ensuring that the coffee is fit for export. That being said, experienced professional trade cuppers are astute identifiers of real quality. They can recognize virtually all aspects to a coffee's growing and preparation in just 5 cups. Some of these cuppers work for famous estates and exporting mills crafting signature flavor profiles from their production area or estate.

The concept of flavor quality, however, is a far more complicated concept to come to an understanding on.  One could erroneously believe that there is some sort of objective standard we could agree on, but here we move away from taste faults into the realm of taste preferences. For the better part of the last century coffee was experienced as a blend. These blend profiles, at least at first, were a roaster's signature, their trademark. Its helpful to remember that Maxwell House Coffee gets its name from the Maxwell House Hotel, who awarded the contract (and name) based on winning a tasting competition. Hills Bros, too, was well regarded for the "Arabian" blend featuring Mocca and Java coffees.

Over the years, though, these brands began competing on price and this put pressure on the coffee buyers to reformulate the blends for price. Before this change in priorities, coffee buyers had specific taste requirements in order to shape the blend. Not only would the coffee need to be clean and defect free, it needed to fulfill a particular taste profile within the blend. This devolved into hopelessly muddled blends, largely indistinguishable from one another where coffee buyers sought the cheapest possible coffee that offended the fewest number of people. With blends consisting of a dozen or more individual components, it is fairly simple to replace one with another and the consumer would be unable to notice any change.  Along with cheapening the beans themselves, there was a push to reduce weight loss during roasting with lighter and lighter roasts, becoming known as "Continental" or simply "American" roasts.

By the 1960's, the lions share of the U.S. coffee market was dominated by just a few roasting firms: Smuckers, who has Folgers; Kraft with Maxwell House; Nestle and Sara Lee. Most coffee sales were through the grocery isle, and couponing dictated who garnered the most sales. As the flavor quality declined in these brands the number of new customers to coffee waned. And for those who continued drinking this swill, the amount of sweeteners and "creaming agents" increased. The National Coffee Association conducted a yearly winter drinking survey and consumption was decreasing every year well into the 1980s.

But it wasn't only about price in blending coffee beans, there were a number of smaller, regional roasters that still relied on flavor quality to lure customers. Some of them date back to the early days of coffee in America like Gillies Coffee of New York. Others were a direct response to the ever worsening quality in commercial coffee, a return to quality, such as Peet's Coffee in California.  These roasters distinguished themselves from the commercial canned coffee by retaining the darker, European style of roasts and sourcing out quality beans that could stand up to such roasts. Ever so slowly, a new breed of roaster began to grow in America, what now is referred snarkily as the second wave.

Roasters such as this relied on specific flavors of coffee that represented their brand. Whether packaged as a single origin or a signature blend, coffees were chosen for their flavor profile. A coffee buyer for these firms would seek out coffees based on these profiles. Some were the "classics" of coffee: Sumatra and Kenya, for example. Others were less well known here in the states, but came from respected estates that had for years prepared special coffees for the European market. These coffees were more carefully sorted and processed, for more exacting coffee buyers. Sometimes you will still see a coffee identified as "European Prep."

In any case, a coffee buyer for these firms expected high quality beans from their sources and rather than trade cupping the coffees for defects, they instead cupped for profile. Rather than roasting the samples very light, the samples would be roasted closer to production temperatures to tease out the potentials of the coffee. In this way a coffee buyer would be able to see if the coffee would fit with the profiles they wished to promote. A coffee buyer here would still be expected to recognize taste faults, but their primary objective was looking for favorable flavor attributes whether that was part of a blend or a stand alone coffee.

Depending on the size of the firm, such cupping would include samples, from production as well to ensure the roasts were coming out right. While this type of cupping differs in style and intent from trade cupping, it was never really identified separately as such. One could call it profile cupping or production cupping, but rarely would someone differentiate it, referring to both simply as cupping.  It was, generally speaking, new territory anyway, and there existed a lack of common language for this type of cupping.

This would become problematic as time progressed. Without a lexicon to describe quality, it made it difficult to define quality. The materials at the time focused around faults and defects, barely mentioning favorable taste attributes beyond something like, clean, balanced, smooth and so forth. So, if you wanted to set out to buy the best coffee you would be hard pressed to describe exactly what that meant. So we can forgive the young man in the beginning of this story for not being capable of defining what he meant by having better beans. The problem was systemic to the trade.

In 1982 many of these roasters gathered together to create a "common forum" to promote quality coffee. The idea was to unite those in the coffee trade to a common purpose: to serve as a sounding board and educate the public; and to generally be a source of support in a world of coffee mediocrity. This group became known as the Specialty Coffee Association of America and is today the world's largest coffee association. Over the years, the SCAA has attempted a number of initiatives designed to promote coffee quality, and naturally one of these would be to develop a standard of what "specialty" coffee is.

Much of this early work consisted of developing guides for common usage. Ted Lingles's 1985 handbook, The Basics of Cupping Coffee, now in its fourth edition, was one such handbook. In it, he outlines his objective stating that it was "written as a sales and marketing tool(,) to promote specialty coffee, adding further that it was "designed to initiate discussion on the most appropriate and descriptive terminology" and "does not presume to be the definitive text."

In addition to producing material, the SCAA began hosting seminars on cupping specialty coffee during its annual exhibition and trade show. In the past, learning to cup coffee was sort of an arcane endeavor, usually reserved for those in the business. Traders would learn from other traders, roasters would learn from roasters. Coffee buyers were often somewhere in between. On the one hand, they needed to be conversant with traders to access quality coffees, but on the other, needed to understand what worked from a production standpoint. A good coffee buyer would need to learn how to navigate these two perspectives. I have known too many roasting firms where there existed an acrimonious divide between the coffee buyer and roaster on what constitutes good coffee. Usually this resulted from a coffee buyer who spent a fair amount of time "in the field," who becave acclimated to trade cupping and lost the  perspective of customer preferences and expectations.

So, establishing a common vocabulary for coffee quality would be a good thing, and training would seem to be the perfect endeavor for the SCAA since its mission is to promote specialty coffee. To this end, it has adopted a program called the Q-Grader Certification that sets forward a systematic framework for evaluating and describing specialty coffee. Using the cupping form originally set out in the Coffee Cupper's Handbook it establishes a training program to certify participants to identify and rate specialty grade coffee. The Q certification is as good as any metric to create a normative vocabulary for assessing quality.

Sadly though, the SCAA has made the same mistake in perspective.

How this mistake in perspective played out is the subject of part two.

Awesome post. Brings a lot of issues into the sun (kinda like how the majority of coffee is grown now). Re: Q-Grader Certification: "I 'represent' that, Sir ..."
You rock, Mark!

My brother's quite a coffee freak! I'm sure he knows about all these ratings. I've always been more into tea myself but I've started drinking coffee more as I've gotten older. I am interested in some healthy creamer alternatives. Do you have any suggestions?!healthy-coffee-creamer/c12ui

Mark Overly said...

I can't say to have any experience with the creamer you have linked. I have tried using grass fed butter and coconut oil as in the Bulletproof coffee model with generally good results.

Nice share Mark, Coffee is best when it is freshly packed by best packaging suppliers. Perfection in packaging doesn't let the coffee beans lose it aroma and freshness. I would suggest all the Coffee/Tea or similar product manufacturers to get your packaging solution from PlasticosMexico - Swiss Pac. Its best in the field of Packaging Solution.

Mark Overly said...

Packaging does not preserve freshness. At best it can only slow the rate of deterioration. Either that package has a valve to release coffee aromas, or the coffee is degassed before packaging. In the first case the coffee will increasingly lack aroma the longer the period from roasting, in the second the coffee's aroma is purge before the package is sealed.
