Today, Yunnan beans appear more and more frequently on the menus of specialty coffee shops, and people habitually refer to them all as "Yunnan small-berry."

2015 WBC champion SaSa Sestic returned as runner-up in the 2022 Australian Brewers Cup, bringing with him a brand-new brewing device called the Paragon—a specially made ice rock mounted in the middle of the dripper to lock in the volatile aromatics in the coffee liquid. According to Sasa, this invention is the result of collaborative research with Professor Jahan and the Swiss Coffee Center of Excellence, and it can capture up to 40% extra aromatics through rapid cooling during the first and middle stages of extraction. However, the official price of this brewing stand plus metal ice rock is as high as $4,292, equivalent to more than 30,000 RMB, which has sparked a lot of discussion among coffee enthusiasts. Bloggers on YouTube have already begun hands-on testing and found that its core component is similar in principle to the food-grade stainless steel ice cubes commonly seen in bars, while similar products on Taobao cost only a few dozen yuan. So what exactly makes this ice rock so special? When brewing the same Geisha with a V60 paired with the Paragon versus a plain V60, the TDS rises from 1.27 to 1.37—what differences are there in flavor performance? This article will explain it all in detail for you. [more…]
