By blending music, science, and coffee culture, the duo has built a unique approach to sharing coffee knowledge and experiences.<\/span><\/p><p><span style=\"font-weight: 400\">Today, AD Cafe has grown to more than 200,000 followers across social platforms, with over a million views on YouTube, continuing to introduce more people to the world of specialty coffee.<\/span><\/p><p><span style=\"font-weight: 400\">During a live brewing session at the 1Zpresso booth at the Taiwan International Coffee Show, Adi demonstrated the K-Ultra hand grinder and showed how grind settings and pouring structure can be used to shape the final flavor profile.\u00a0<\/span><\/p><p><span style=\"font-weight: 400\">Rather than simply sharing brewing recipes, he focused on a bigger idea: how every brewing decision directly shapes the final cup.<\/span><\/p><h2><b>The K-Ultra Flavor Profile: Rich Sweetness and Fuller Body<\/b><\/h2><p><span style=\"font-weight: 400\">At the beginning of the session, Adi asked the audience a simple question:<\/span><\/p><p><span style=\"font-weight: 400\">\u201cDo you prefer aroma, or mouthfeel?\u201d<\/span><\/p><p><span style=\"font-weight: 400\">He shared that he personally leans toward coffees with more sweetness and body, and in his opinion, the K-Ultra fits naturally into that style of brewing.<\/span><\/p><p><span style=\"font-weight: 400\">According to Adi, the K-Ultra tends to produce:<\/span><\/p><ul><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Pronounced sweetness<\/span><\/li><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">A fuller, heavier mouthfeel<\/span><\/li><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">A balanced presentation of texture and aroma<\/span><\/li><\/ul><h2><b>How the K-Ultra\u2019s Grind Profile Affects Pour Over Flavor<\/b><\/h2><p><span style=\"font-weight: 400\">Adi also mentioned that because the K-Ultra is designed to handle espresso grinding as well, it tends to produce slightly more fines compared to grinders optimized specifically for pour over.<\/span><\/p><p><span style=\"font-weight: 400\">As a result, when used for pour over coffee, the K-Ultra often delivers a denser and richer cup profile with more body and structure.<\/span><\/p><h2><b>The K-Ultra User Experience: Fast and Effortless Grinding<\/b><\/h2><p><span style=\"font-weight: 400\">Beyond flavor performance, Adi also highlighted the grinder\u2019s usability.<\/span><\/p><p><span style=\"font-weight: 400\">He said there are two things he pays close attention to when evaluating a hand grinder:<\/span><\/p><ul><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">How much effort the grinding requires<\/span><\/li><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">How long the grinding process takes<\/span><\/li><\/ul><p><span style=\"font-weight: 400\">In his experience, the K-Ultra performs especially well in both areas:<\/span><\/p><ul><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Grinding feels effortless<\/span><\/li><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">The process is fast and efficient<\/span><\/li><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">It can even handle espresso grinding comfortably<\/span><\/li><\/ul><h2><b>AD Cafe\u2019s Pour-over Recipe<\/b><\/h2><h3><b>Brewing Parameters<\/b><\/h3><ul><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Coffee dose: 20g<\/span><\/li><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Grind setting: K-Ultra 7.5<\/span><\/li><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Water

style=\"font-weight: 400\">Pour slowly in circular motions from the center outward, making sure the center of the coffee bed is fully saturated<\/span><\/li><\/ul><p><b>First Pour<\/b><\/p><ul><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Pour up to 140g total water<\/span><\/li><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Use a heavier center pour to bring out brighter acidity<\/span><\/li><\/ul><p><b>Second Pour<\/b><\/p><ul><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Pour up to 240g total water<\/span><\/li><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Use a gentler pour around the outer edge to extend extraction and increase sweetness<\/span><\/li><\/ul><p><b>Final Pour<\/b><\/p><ul><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Pour up to 300g total water<\/span><\/li><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Increase the flow rate to speed up drawdown and control the overall extraction time<\/span><\/li><\/ul><h2><b>AD Cafe\u2019s Brewing Tips<\/b><\/h2><h3><b>Do You Need to Rinse the Paper Filter?<\/b><\/h3><p><span style=\"font-weight: 400\">Adi mentioned that modern paper filters have improved significantly, so skipping the rinse step usually does not introduce noticeable paper flavors.<\/span><\/p><p><span style=\"font-weight: 400\">That said, he still prefers rinsing the filter because it helps the paper adhere more securely to the dripper and improves brewing consistency.<\/span><\/p><h2><b>Final Thoughts on the 1Zpresso K-Ultra<\/b><\/h2><p><span style=\"font-weight: 400\">Adi described the K-Ultra as his current favorite grinder and one he regularly uses in daily brewing.<\/span><\/p><p><span style=\"font-weight: 400\">In terms of flavor, he believes the K-Ultra leans toward sweetness and mouthfeel, producing cups with higher sweetness, fuller body, and a balanced presentation between texture and aroma.<\/span><\/p><p><span style=\"font-weight: 400\">Because the grinder is also capable of espresso grinding, it tends to generate relatively more fines than grinders built specifically for pour over brewing. That characteristic contributes to a stronger sense of body and structure in the cup.<\/span><\/p><p><span style=\"font-weight: 400\">When used for pour over brewing, the K-Ultra tends to produce a richer and fuller-bodied cup.\u00a0<\/span><\/p><p><span style=\"font-weight: 400\">From a usability standpoint, Adi also emphasized the grinder\u2019s efficiency and ease of use. He noted that the grinding action feels smooth, requires little effort, and does not take many rotations to finish grinding.<\/span><\/p><p><span style=\"font-weight: 400\">For Adi, the K-Ultra is not only a grinder that matches his flavor preferences, but also one that balances cup quality with an enjoyable day-to-day grinding experience.<\/span><\/p><p><span style=\"font-weight: 400\">With the right pouring technique, brewers can further shape acidity, sweetness, and body by adjusting pouring position and flow rate.\u00a0<\/span><\/p><p><a
