Since winning the title, Sherry has continued visiting coffee-producing regions around the world, coaching brewers from different countries, sharing her experience with coffee professionals and competitors.<\/span><\/p><p><span style=\"font-weight: 400\">She also founded Sherry Selection, a curated coffee brand focused on making specialty coffee more approachable for everyday drinkers.<\/span> \u00a0<\/p><h2><b>Why the Same Coffee Can Taste Different<\/b><\/h2><p><span style=\"font-weight: 400\">Why can the same coffee taste noticeably different depending on who brews it?<\/span><\/p><p><span style=\"font-weight: 400\">Sweetness, clarity, and flavor complexity are influenced not only by the beans themselves, but also by grinding and brewing variables.<\/span><\/p><p><span style=\"font-weight: 400\">During the 1Zpresso brewing session at the Taiwan International Coffee Show, Sherry shared her thoughts on brewing while preparing coffee live for the audience.<\/span><\/p><p><span style=\"font-weight: 400\">From grinder characteristics and fines production to pouring structure and water temperature, she explained how different variables can influence sweetness, flavor layering, and clarity in the cup.<\/span> <span style=\"font-weight: 400\">Through the session, she explored several key questions:<\/span><\/p><ul><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">What role do fines play during extraction?<\/span><\/li><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">How should grinder selection relate to flavor preference?<\/span><\/li><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">How do pouring rhythm and flow rate influence body and clarity?<\/span><\/li><\/ul><p><span style=\"font-weight: 400\">These small adjustments often play an important role in how different coffees express themselves during brewing.<\/span> \u00a0<\/p><h2><b>1Zpresso: The Grinder Sherry Used to Win WBrC<\/b><\/h2><p><span style=\"font-weight: 400\">At the beginning of the demonstration, Sherry mentioned that she used a 1Zpresso K Series grinder during her winning run at the 2022 World Brewers Cup Championship.\u00a0<\/span> <span style=\"font-weight: 400\">She also introduced several design features of the 1Zpresso K-Ultra.<\/span><\/p><ul><li><b>Foldable Handle Design<\/b><\/li><\/ul><p><span style=\"font-weight: 400\">The foldable crank handle makes the grinder more compact for travel, while the extended handle provides more leverage during grinding.\u00a0<\/span> <span style=\"font-weight: 400\">According to Sherry, this becomes especially noticeable when grinding finer settings for espresso or moka pot brewing, where grinding resistance becomes more noticeable.\u00a0<\/span><\/p><ul><li><b>External Adjustment Dial<\/b><\/li><\/ul><p><span style=\"font-weight: 400\">The external adjustment ring allows grind size changes to be made more quickly and intuitively.<\/span> \u00a0<\/p><h2><b><a href=\"https:\/\/1zpresso.coffee\/k-ultra\/\">The K-Ultra<\/a> Grinding Characteristics and Flavor Presentation<\/b><\/h2><p><span style=\"font-weight: 400\">When discussing the grinding characteristics of the K-Ultra, Sherry noted that the grinder produces slightly more fines [1] compared to the ZP6 [2] .<\/span><\/p><p><span style=\"font-weight: 400\">According to her observations, this can contribute to a fuller sweetness profile in pour over brewing.<\/span><\/p><p><span style=\"font-weight: 400\">She also mentioned that the slightly higher fines content allows the K-Ultra to work across both pour over and espresso brewing styles, since espresso extraction generally benefits from having a certain amount of fines present.<\/span> \u00a0<\/p><p><b>Editor&#8217;s Notes:<\/b><\/p><ol><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">The 1Zpresso K-Ultra is designed as a multi-purpose grinder within the 1Zpresso lineup, supporting a wide range of brewing methods, including espresso, moka pot, pour over, siphon, AeroPress, French press, and cold brew.\u00a0<\/span><\/li><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">The 1Zpresso ZP6 was developed specifically for pour over brewing and is known for its relatively low fines production within the 1Zpresso lineup. It was also used by 2023 World Brewers Cup Champion Carlos Medina during competition.<\/span><\/li><\/ol><h2><b>How Fines Influence Coffee Flavor<\/b><\/h2><p><span style=\"font-weight: 400\">Sherry mentioned that fines are not necessarily a negative factor during brewing.<\/span> <span style=\"font-weight: 400\">In moderate amounts, fines may contribute to:<\/span><\/p><ul><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Increased sweetness<\/span><\/li><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Higher concentration<\/span><\/li><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">More layered flavor presentation\u00a0<\/span><\/li><\/ul><p><span style=\"font-weight: 400\">At the same time, higher amounts of fines may also create challenges during extraction, including:<\/span><\/p><ul><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Over-extraction<\/span><\/li><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Increased bitterness<\/span><\/li><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Unwanted flavors<\/span><\/li><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Slower drawdown or filter clogging<\/span><\/li><\/ul><h2><b>Choosing a Grinder Based on Flavor Preference<\/b><\/h2><p><span style=\"font-weight: 400\">Sherry explained that grinders designed for both espresso and pour over generally produce more fines than grinders designed specifically for pour over brewing.<\/span><\/p><p><span style=\"font-weight: 400\">When choosing a grinder, she suggested considering the flavor profile you prefer.<br \/><\/span><br \/><b>If You Prefer\uff1a<\/b><\/p><ul><li style=\"font-weight: 400\"><b>Sweeter, fuller cups\u00a0 -&gt;

She mentioned that using a larger stream during the final stage may help keep the final stage of extraction cleaner.<\/span> <span style=\"font-weight: 400\">She shared two common flow rate ranges she often uses:<\/span><\/p><ul><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Faster flow: approximately 10g per second or higher<\/span><\/li><li style=\"font-weight: 400\"><span style=\"font-weight: 400\">Slower flow: approximately 3 to 5g per second<\/span><\/li><\/ul><h3><b>Center Pouring to Reduce Late-Stage Extraction<\/b><\/h3><p><span style=\"font-weight: 400\">Toward the end of brewing, Sherry sometimes changes her pouring structure depending on the extraction characteristics of the coffee. <\/span><span style=\"font-weight: 400\">In some cases, she switches from circular pouring to a center-only pour during the final stage.<\/span><\/p><p><span style=\"font-weight: 400\">She explained that continuous circular pouring creates more agitation throughout different parts of the coffee bed, while center pouring keeps the coffee bed more stable.<\/span> <span style=\"font-weight: 400\">When most of the coffee\u2019s primary flavors have already been extracted earlier in the brew, reducing agitation may help keep the later stage of extraction gentler.<\/span> <span style=\"font-weight: 400\">In some situations, she also combines center pouring with lower water temperatures to reduce the risk of over-extraction and bitterness during the final stage of brewing.<\/span> \u00a0<\/p><h2><b>World Champion Sherry&#8217;s Review on 1Zpresso K-Ultra<\/b><\/h2><p><span style=\"font-weight: 400\">During the Taiwan International Coffee Show demonstration, Sherry used different brewing examples to share her observations on how grinder characteristics can influence flavor.<\/span><\/p><p><span style=\"font-weight: 400\">According to her experience, the 1Zpresso K-Ultra produces a grind profile with a certain amount of fines, which can contribute to fuller sweetness, more concentration, and more layered flavors.<\/span><\/p><p><span style=\"font-weight: 400\">She also noted that this grinding characteristic allows the grinder to work across both pour over and espresso brewing styles.<\/span><\/p><p><span style=\"font-weight: 400\">From the foldable handle design to the smooth bearing structure, the grinder is also designed to remain comfortable to use when grinding finer settings for espresso or moka pot brewing.<\/span><\/p><p><span style=\"font-weight: 400\">Throughout the session, Sherry emphasized how coffee flavor is shaped by the interaction of multiple variables, including grind distribution, fines production, pouring rhythm, water temperature, and extraction control.<\/span><\/p><p><span style=\"font-weight: 400\">By understanding these variables, brewers can make more informed adjustments during brewing and better explore how different coffees respond to changes in extraction.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-c91f5e3 e-con e-atomic-element e-flexbox-base
