If you are a coffee lover, you probably know that not all coffees are created equal. Some coffees have a distinctive flavor, aroma, body, and acidity that make them stand out from the rest. These coffees are called specialty coffees, and they are graded according to strict standards by the Specialty Coffee Association of America (SCAA).

One of the most important aspects of grading specialty coffee is evaluating the quality of green coffee beans, which are the raw material for roasting and brewing. Green coffee beans can have various defects that affect their appearance, taste, and health. These defects can be caused by factors such as pests, diseases, processing methods, storage conditions, and transportation.
To help coffee professionals and enthusiasts identify and classify green coffee defects, the SCAA has developed a comprehensive guide called the Arabica Green Coffee Defect Handbook. This handbook provides detailed descriptions, photos, and classifications of different types of defects that can be found in green coffee beans. It also explains how to calculate the defect equivalents and the grade of the coffee based on a 350-gram sample.
The SCAA Arabica Green Coffee Defect Handbook is an essential tool for anyone who wants to improve their knowledge and skills in green coffee evaluation. It can help you ensure that you are buying, selling, roasting, or brewing high-quality specialty coffee that meets the SCAA standards. It can also help you avoid wasting money, time, and resources on low-quality or contaminated coffee.

How to use the SCAA handbook for green coffee defects
Now that you have downloaded the SCAA handbook for green coffee defects, you might be wondering how to use it effectively. Here are some tips on how to use the handbook for different purposes:
How to identify and classify different types of defects
The first step in using the handbook is to familiarize yourself with the different types of defects that can occur in green coffee beans. The handbook divides these defects into two categories: Category 1 (primary) defects and Category 2 (secondary) defects.
Category 1 defects are those that have a major impact on the quality of the cup, such as full black beans, full sour beans, fungus damaged beans, foreign matter, and severe insect damage. Category 2 defects are those that have a minor impact on the quality of the cup, such as partial black beans, partial sour beans, dried cherry/pods, parchment/hulls/husks, immature/withered beans, broken/chipped/cut beans, shells, floaters, and slight insect damage.
The handbook provides clear pictures and physical descriptions of each defect type. You can use these pictures and descriptions as a reference when you inspect your green coffee beans. You can also use a magnifying glass, a scale, a sieve, and a moisture meter to help you identify and measure the defects more accurately.
How to calculate the defect equivalents and the grade of the coffee
The next step in using the handbook is to calculate the defect equivalents and the grade of the coffee based on the SCAA Green Arabica Coffee Classification System (GACCS). The GACCS determines the conversion or equivalent of single defects to full defects. The number of full defects are calculated on a basis of 350 grams of green coffee sample.
A full defect can be either a Category 1 or a Category 2 defect. Specialty Grade samples must have zero Category 1 defects and no more than five Category 2 defects. Below Specialty Grade samples must have no more than five Category 1 defects and no more than 15 Category 2 defects.
To calculate the defect equivalents, you need to count the number of single defects in your sample and multiply them by their corresponding conversion factor. For example, one full black bean equals one full defect, but three partial black beans equal one full defect. You can find the conversion factors for each defect type in the handbook.
To calculate the grade of the coffee, you need to add up the total number of full defects in your sample and compare it with the SCAA GACCS criteria. For example, if your sample has zero Category 1 defects and four Category 2 defects, it is considered Specialty Grade. If your sample has three Category 1 defects and ten Category 2 defects, it is considered Below Specialty Grade.
How to fill out the green grading form
The final step in using the handbook is to fill out the green grading form that is provided by the SCAA. This form is a standardized way of recording and reporting your green coffee evaluation results. You can download the form from this link: .
The form requires you to write your name, date, and sample identification code number in the space provided. You also need to specify the grade of the coffee in the space provided on the form stating one of the following classifications: Specialty Grade, Below Specialty Grade, or Not Classified by SCAA GACCS.
You also need to show the calculation from individual defects to full defect equivalent. You can use a table or a list format to show your calculation. You need to summarize the total number of Category 1 and Category 2 defects in your sample and record them on the upper right hand corner box of the grading form.
How to improve your green coffee quality with the SCAA handbook
Besides using the SCAA handbook for green coffee defects for evaluation purposes, you can also use it for improvement purposes. The handbook can help you prevent and reduce common defects in green coffee by providing you with some best practices and recommendations on how to handle green coffee properly. Here are some tips on how to improve your green coffee quality with the SCAA handbook:
How to prevent and reduce common defects in green coffee
Many of the defects in green coffee are caused by factors that can be controlled or minimized by following good agricultural and processing practices. For example, you can prevent or reduce pest and disease damage by applying integrated pest management techniques, such as using resistant varieties, pruning, weeding, mulching, and biological control. You can also prevent or reduce souring and fungal damage by harvesting ripe cherries, sorting out defective cherries, washing and drying them properly, and avoiding over-fermentation.
The handbook provides some general guidelines on how to prevent and reduce common defects in green coffee. However, you should also consult with local experts and extension agents who can advise you on specific practices that are suitable for your region and climate.
How to store and transport green coffee properly
Another factor that can affect the quality of green coffee is how it is stored and transported from the farm to the roaster or buyer. Improper storage and transportation can expose green coffee to moisture, heat, light, oxygen, pests, contaminants, and physical damage that can degrade its quality and cause defects.
To store and transport green coffee properly, you should follow these general rules:
Store green coffee in a cool, dry, dark, well-ventilated place away from direct sunlight, heat sources, strong odors, chemicals, and moisture.
Use clean, dry, breathable bags or containers that are made of natural materials such as jute or cotton. Avoid using plastic bags or containers that can trap moisture and cause mold growth.
Label each bag or container with relevant information such as origin, variety, grade, lot number, date of harvest, date of shipment, etc. 71b2f0854b
