Alchemy IV<\/strong> est destin\u00e9 \u00e0 la production de caract\u00e8res intenses de fruits rouges (cerise, framboise, groseille et grenade) dans les vins. Cet assemblage est un tr\u00e8s grand producteur d'esters \u00e9thyliques, en particulier d'hexanoate d'\u00e9thyle (fruit\u00e9), ce qui contribue \u00e0 la long\u00e9vit\u00e9 des ar\u00f4mes de fruits. Cela le rend tr\u00e8s appropri\u00e9 pour les vins de garde qui conservent leurs caract\u00e8res intenses de fruits rouges.<\/p>\n

Cet assemblage pr\u00e9sente \u00e9galement une production significative d'esters totaux et de terp\u00e8nes (fruit\u00e9s et violets). Ce qui est commun aux deux assemblages rouges Alchemy est leur tr\u00e8s forte contribution fruit\u00e9e due \u00e0 une production plus \u00e9lev\u00e9e d'esters totaux et d'hexanoate d'\u00e9thyle. Ceci est encore am\u00e9lior\u00e9 par le \u00df-damasc\u00e9none (violettes) et une diminution des m\u00e9thoxy-pyrazines (qui peuvent masquer les caract\u00e8res fruit\u00e9s).<\/p>\n

Alchemy IV<\/strong> produit des vins avec une intensit\u00e9 aromatique significative, qui sont ronds et souples, et convient \u00e0 tous les c\u00e9pages rouges.<\/p>","product_results_benefits":"
