pour styles注水方式

Water does not only add mass. Its path changes agitation, drawdown, and which parts of the coffee bed extract fastest.水不只是增加重量。水流的路径会改变扰动、流速，以及咖啡粉床不同区域的萃取速度。

  1. spiral螺旋

    Start near the center and expand outward in a controlled spiral, then return inward if the recipe calls for it.从中心附近开始，稳定地向外画螺旋；如果配方需要，再从外圈回到中心。

    Even wetting and moderate agitation tend to support clarity and sweetness without pushing the edges of the bed too hard.均匀润湿和适度扰动通常会带来清晰度与甜感，同时避免过度冲刷粉床边缘。

  2. circular绕圈

    Move in steady rings around the bed, keeping the stream away from the paper wall unless the brewer asks for bypass.沿着粉床稳定绕圈，除非配方需要旁通，否则尽量不要把水直接冲到滤纸壁上。

    More perimeter movement raises agitation and can increase extraction, body, and brightness when the grind and flow are balanced.更多外圈移动会提高扰动，研磨和流速合适时，可能增加萃取、醇厚度和明亮感。

  3. center中心

    Hold the stream near the middle so water falls through a smaller area with less lateral movement.将水流保持在中间区域，让水通过较小的范围下落，减少横向扰动。

    Lower agitation can soften acidity and reduce harshness, but too much center pouring can leave the outer bed under-extracted.较低扰动可以柔化酸质并降低粗糙感，但过多中心注水可能让外圈粉床萃取不足。

  4. swirl摇晃

    Rotate or gently shake the brewer after pouring to level the bed and move fines through the slurry.注水后轻轻旋转或摇晃滤杯，让粉床更平整，并让细粉在浆液中重新分布。

    Swirling can improve uniformity and sweetness, while too much movement may slow drawdown and add dryness.摇晃有助于提高均匀度和甜感；过度摇晃则可能拖慢流速，并带来干涩感。
