Welcome to this newest episode of Behind the Roast. Willem discusses the subject ‘Filter coffee’. Last month Willem talked about the Giesen Roast Profiler. Missed that one? Click here. Enjoy the eighth episode of ‘Behind the Roast’ with Willem Boot!
Filter coffee is one of the most popular ways of preparing coffee at home, accounting for over 65% of all coffee consumption in western countries. In this article, we explore different methodologies and technologies for preparing traditional filtered coffee, including the well-known V60 and Chemex coffeemakers, the lesser-known Karlsbad, and the newly introduced Spinn coffee brewer.
The History of the Chemex Coffeemaker
The CHEMEX® coffeemaker was invented in 1941 by the chemist Dr. Peter Schlumbohm, who developed over 300 patents during his career. He focused on making everyday objects more functional, attractive, and enjoyable to use. Schlumbohm’s knowledge of the chemistry behind flavor and caffeine extraction from coffee beans led him to invent the double-bonded CHEMEX® paper filters for a perfect extraction every time. He also designed the iconic hourglass shape, which has become a part of American coffee history. The CHEMEX® is recognized and awarded by both the scientific community and the art and design communities.
The Story of the V60 Dripper
The V60 dripper is designed by Hario, a company founded in Tokyo in 1921 that produces and sells physical and chemical-use glass products. Hario Glass uses 100% natural minerals to refine heatproof glass, making it environmentally friendly. In 1949, Hario launched its first home product: a glass filter coffee siphon, which evolved into a cloth filter coffee siphon by 1957. Hario has received hundreds of design awards, yet it’s the V60, launched more than ten years ago, that became its most famous invention. The name comes from vector 60, the 60º angle of its cone.
The Karlsbad Coffee Maker
The Karlsbad Coffee Maker is made from 100% ceramic materials, including a triple-layered ceramic filter, and is designed to brew coffee without any foreign taste, ensuring the purest aroma. To use it, pour 15 to 20 grams of coarsely ground coffee directly into the porcelain filter holder of the top container. Place the water distributor on top and slowly pour in hot water. Once finished brewing, place the hollow lid on top of the coffee pot and wait five minutes before serving the coffee. When poured into cups, you can smell the condensed aroma inside the lid, allowing you to judge the aromatic finesse of the brew.
The Spinn Coffee Maker
The Spinn Coffee Maker, developed by a team of Dutch engineers and entrepreneurs, uses a centrifuge and water jets to extract coffee. It comes with a built-in grinder and offers pre-set coffee options, including drip, Americano, espresso, and cold brew. The regular drip coffee option offers a good quality brew, and the machine is an excellent alternative to wasteful brewing systems that rely on cups and capsules. The Spinn is marketed as an all-in-one package that also features an app and Wi-Fi connectivity.
Filter coffee is a trusted way of preparing a delicious cup of coffee at home, and there are many methods and technologies to achieve the perfect brew. The Chemex, V60, Karlsbad, and Spinn are all excellent options, each with its own unique features and benefits. By experimenting with different methods, coffee lovers can find their ideal way of brewing and enjoy the science and fun of preparing a perfect cup of filter coffee.
