      <video:title>Distilling Workflow Introduction</video:title>
      <video:description>A guiding idea for the course: treat craft distilling as an end-to-end process. It challenges the habit of obsessing over the still and reframes why mashing and fermentation matter so much.</video:description>

      <video:title>蒸留ワークフロー入門</video:title>
      <video:description>本コースを貫く考え方は、クラフト蒸留を最初から最後までの一連のプロセスとして捉えることです。蒸留機だけに意識を集中する従来の発想を見直し、糖化と発酵がなぜ重要なのかを捉え直します。</video:description>

      <video:title>Introducción al flujo de trabajo de la destilación</video:title>
      <video:description>Una idea central del curso: abordar la destilación artesanal como un proceso integral. Este enfoque cuestiona la tendencia a obsesionarse con el alambique y replantea por qué la maceración y la fermentación son tan importantes.</video:description>

      <video:title>Distilling Process Steps</video:title>
      <video:description>A clear walkthrough of distilling as a process: mashing, fermentation, stripping, finishing/cuts, aging, then bottling and selling. It emphasizes that fermentation creates most flavor and that inefficiencies compound across steps.</video:description>

      <video:description>蒸留を一連のプロセスとして明快に解説します。糖化、発酵、初留、仕上げ蒸留／カット、熟成、瓶詰め、販売までを順にたどり、風味の大部分が発酵で生み出されること、各工程の非効率が積み重なることを説明します。</video:description>

      <video:title>Etapas del proceso de destilación</video:title>
      <video:description>Un recorrido claro por el proceso de destilación: maceración, fermentación, primera destilación, destilación final y cortes, añejamiento y, por último, embotellado y venta. Se destaca que la fermentación crea la mayor parte del sabor y que las ineficiencias se acumulan en cada etapa.</video:description>

      <video:title>Desafíos al ampliar la escala de una destilería</video:title>
      <video:description>La trampa de ampliar la escala con equipos de destilería compartimentados y un enfoque diferente: todas estas etapas son procesos controlados de calentamiento y enfriamiento, por lo que es posible diseñar con flexibilidad. La sección concluye con una invitación a pensar de forma crítica y hacer preguntas.</video:description>

      <video:title>El problema de la gestión manual</video:title>
      <video:description>La gestión de la refrigeración permite ajustar la graduación alcohólica, pero la operación manual es vulnerable a los cambios en la temperatura del agua, la temperatura ambiente, la presión del agua y la presión atmosférica. Descubra por qué estas variables alteran el comportamiento del vapor y cómo la inconsistencia se manifiesta en cortes imprecisos y solapamientos no deseados entre fracciones.</video:description>

      <video:title>Liquid Management: Repeatability</video:title>
      <video:description>Liquid management condenses all rising vapor and controls reflux by managing liquid output instead of vapor throughput. Learn how this removes several confounders in traditional cooling management and improves repeatability across seasons and conditions.</video:description>

      <video:title>Fruit Brandy vs Whiskey Stills</video:title>
      <video:description>Many traditional plated systems are optimized for fruit brandy: wide columns and tails-trapping behavior that protects fragile, front-of-mouth flavors. Learn why that optimization can be a trap for whiskey and rum, and what to ask before investing in equipment.</video:description>

      <video:title>Copper Risks in Distillation</video:title>
      <video:description>Copper can reduce sulfur harshness, but it’s also not inert: it oxidizes, requires heavy cleaning, can carry over flavors between runs, and can contribute to copper residues and ethyl carbamate formation over time.</video:description>

      <video:title>蒸留における銅のリスク</video:title>
      <video:description>銅は硫黄由来の刺激を低減できますが、不活性ではありません。酸化するため徹底した洗浄が必要で、蒸留バッチ間の風味の持ち越しを招くほか、時間の経過とともに銅残留物やカルバミン酸エチルの生成につながる可能性があります。</video:description>

      <video:title>Riesgos del cobre en la destilación</video:title>
      <video:description>El cobre puede reducir las notas azufradas agresivas, pero no es inerte: se oxida, exige una limpieza intensiva, puede transferir sabores de una operación a otra y, con el tiempo, contribuir a la presencia de residuos de cobre y a la formación de carbamato de etilo.</video:description>

      <video:title>Wide vs Narrow Boilers</video:title>
      <video:description>Boiler geometry changes surface area, which changes boil-up intensity. Learn why narrow boilers force lower fill rates, create internal inefficiencies, and can destabilize vapor speeds, while wide boilers support steadier vapor beds and more consistent cuts.</video:description>

      <video:title>幅広型と細長型の蒸留釜</video:title>
      <video:description>蒸留釜の形状が変わると表面積が変わり、沸き上がりの強さにも影響します。細長型では充填率を下げる必要があり、内部効率の低下や蒸気速度の不安定化を招く一方、幅広型では蒸気層が安定し、より一貫したカットが可能になる理由を学びます。</video:description>

      <video:title>Calderas anchas frente a estrechas</video:title>
      <video:description>La geometría de la caldera modifica la superficie y, con ello, la intensidad de ebullición. Descubra por qué las calderas estrechas obligan a reducir el nivel de llenado, generan ineficiencias internas y pueden desestabilizar la velocidad del vapor, mientras que las calderas anchas favorecen un lecho de vapor más estable y cortes más uniformes.</video:description>

      <video:title>Fermentation Time and Flavor Development</video:title>
      <video:description>Learn why this approach argues against “ferment just for yield”: while alcohol rises quickly in the first 3 days, much esterification happens later when alcohol is present for reactions.</video:description>

      <video:description>Descubra por qué este enfoque cuestiona la idea de «fermentar solo para maximizar el rendimiento»: aunque el alcohol aumenta rápidamente durante los primeros 3 días, gran parte de la esterificación ocurre después, cuando ya hay alcohol disponible para las reacciones.</video:description>

      <video:description>発酵制御と「Holy Trinity」のテイスティングモデルを関連付けます。pHを下げると後留（テール）に由来する奥行きが増し、温度を上げると前留（ヘッズ）の果実香が強まり、時間を延ばすと中盤の風味が充実します。</video:description>

      <video:title>酵母へのストレス、温度、pH</video:title>
      <video:description>基本となる考え方を学びます。酵母株だけで風味特性が決まるわけではありません。風味の方向性は酵母と環境の組み合わせ、特に温度とpH（酸味）によって決まります。</video:description>

      <video:description>Comprenda esta afirmación fundamental: la cepa de levadura por sí sola no crea un perfil de sabor. La orientación del sabor surge de la combinación de la levadura y su entorno, especialmente de la temperatura y el pH (acidez).</video:description>
