Alchemy I <\/strong>am\u00e9liore principalement les esters fruit\u00e9s et floraux et, dans une moindre mesure, les thiols volatils (ar\u00f4mes de fruit de la passion, de pamplemousse, de groseille \u00e0 maquereau et de goyave) dans les vins blancs. <\/p>\n

Cet effet est le r\u00e9sultat de l'action synergique des souches de levure sp\u00e9cifiques utilis\u00e9es dans le m\u00e9lange. Le rapport des souches de levure dans le m\u00e9lange a \u00e9t\u00e9 scientifiquement formul\u00e9<\/strong> pour fournir ce profil aromatique optimal. Il est recommand\u00e9 pour la vinification de c\u00e9pages blancs tels que le Chardonnay, le Chenin blanc, le Verdelho, le Riesling, le Pinot gris et le Sauvignon blanc de style tropical.<\/p>","product_results_benefits":"","product_characteristics":"
