The frustration of inconsistent extractions is a common problem many face during the coffee-making process. One minute, your shot looks perfectly dialed in, but the next, you are left wondering why you have a watery, under-extracted shot or a slow, over-extracted shot. Extraction instability is caused by several environmental factors that constantly affect your coffee beans and coffee grinder. For example, when coffee beans are opened from their packaging, they are immediately exposed to oxygen. Exposure to oxygen, or oxidation, degrades the coffee bean's structure over time, making it more brittle and less able to retain water. This structural change causes water to flow more quickly through the coffee puck, leading to a considerably faster extraction. Oxidation is also the most common reason why older coffee beans are particularly difficult to dial in. Another environmental factor that affects extraction stability is heat. During peak hours, coffee grinders, specifically their grinding chamber and grinding burrs, become very hot due to continuous use. Excessive heat causes thermal expansion in the grinding burrs, thus reducing the distance between burrs and resulting in a finer grind. Furthermore, the additional friction from a finer grind setting can cause coffee grounds to clump together, reducing water flow while further compounding the over-extraction problem. All of these variables can severely affect your grind consistency if left unchecked. Luckily, with new technologies come innovative new solutions. In recent years, Mahlkönig has updated its revolutionary Grind-by-Weight grinders with a new automated system known as Grind-by-Sync. To maintain espresso consistency with smart technology, Mahlkönig Grind-by-Sync combines existing Grind-by-Weight technology with intelligent machine-to-machine integration between the espresso machine and grinder. Through a patented algorithm, the Sync system records timing for each shot on the espresso machine; if extraction is consistently faster or slower than the preset target, it communicates with the grinder to adjust the grind size accordingly. Through its DDD (Disc Distance Detection) technology & AGSA motorized grind adjustment module, Grind-by-Sync grinders automatically adjust grind size to the setting recommended by the Sync system. All of this adjustment happens automatically in the background, allowing users to focus on making coffee without worrying about periodically checking and manually adjusting the grind size. Altogether, Mahlkönig's new sync system revolutionizes the way you interact with your coffee grinder. By automating the time-consuming and periodic process of manual grind adjustment, your grinder becomes an advanced coffee-making assistant in your operation, effectively eliminating the workload, frustration, and reduction in quality caused by inconsistent extractions.
