Coffee Part IV: What's brewin?

What *is* brewing?

The brewing process of coffee consists of cooking the ground beans, which plays a key role in extracting the flavor and antioxidants from the coffee we consume. The brewing process combines science and technology to create the perfect cup of java. Picking the right beans is the most important factor in brewing. N4L’s Organic Antioxidant Rich Coffee includes specialty-grade whole arabica beans that are high in antioxidants and natural compounds to produce the freshest cup with a unique flavor profile.

 

Roasting the beans at a high temperature of around 200°C is highly important in reducing the level of acrylamides, chlorogenic acids, and aldehydes that naturally build up in coffee beans.1 These compounds can contribute to an overly bitter taste, so this step in the brewing process is center focus at N4L. Brewing not only impacts flavor, but also preserves the beneficial antioxidants in the coffee.

Simple Guide to Brewing 2

  • Use clean, fresh, chemical-free water, such as pure spring water.
  • Grind the coffee to match your brewing method, whether for use in a French press, an espresso machine, or some other method.
  • Use the recommended coffee-to-water ratio for your brew method. A commonly used ratio is 18-22 grams ground coffee per 350 ml water, which is roughly 4-5 tablespoons of whole bean coffee.
  • Use a method with a paper filter if cholesterol is a concern to your health. Using a paper filter can help reduce cafestol levels, a diterpene that can raise cholesterol levels in the blood, while also allowing the caffeine and beneficial antioxidants to pass through. 3
  • Brew using water between 195⁰-205⁰F (92⁰-96⁰C) for 3 to 5 minutes.
  • Always keep brewing equipment clean.
  • Store coffee in an airtight container away from light, heat and moisture.

Top 3 Techniques

1.Burr Grinder
Burr grinders are one of the two types of grinders used to grind fresh coffee beans. They provide high quality coffee by evenly grinding the beans. The beans should be ground within minutes of brewing to avoid loss of flavor, aroma and antioxidants. It is also crucial to select the correct level of coarseness, depending upon the brewing method you are using.4 A burr grinder can grind the beans to any desired level of coarseness while keeping the grounds even in size for a smoother brew. N4L’s whole coffee beans are minimally processed to retain high concentration of the health promoting polyphenols. It is important to wait to grind the beans until you are ready to brew the coffee.
If you are seeking a grinder that requires less maintenance at a lower price, a blade grinder would get the job done as well.
2. French Press
The French Press brewing method is ideal for time and temperature control and offers unmatched flavor by extracting the volatile oils that are often trapped in paper filters when using other brewing methods. The coarsely ground beans are exposed to a hot water pour, then pressed with a plunger and left to infuse for 4-5 minutes, depending on desired intensity.5 This simple method of brewing is great for N4L’s coffee as it brings out the nutty cocoa flavor and undertones of black tea and Jasmine. 
3. Filtered Methods
Many types of coffee brewing machines involve the use of a filter, usually a paper filter. Machines such as an automatic drip, Kalita 185, commercial batch brewer, and a siphon filter the ground beans to ensure reduction of any harmful compounds while keeping the flavor and antioxidant concentration high.5 Unbleached paper coffee filters or reusable hemp coffee filters are a few sustainable options for any filtered coffee machine.
