Alchemy III est destin\u00e9 \u00e0 la production de vins rouges complexes. Cet assemblage est un tr\u00e8s grand producteur de 2-ph\u00e9nyl-\u00e9thanol (rose), d'ac\u00e9tate de 2-ph\u00e9nyl\u00e9thyle (floral et fruit\u00e9), de \u00df-ionone (framboise) et d'esters d'ac\u00e9tate (fruit\u00e9 et bonbon). Commun aux deux assemblages rouges Alchemy est leur tr\u00e8s forte contribution aux ar\u00f4mes fruit\u00e9s gr\u00e2ce \u00e0 une production plus \u00e9lev\u00e9e d'esters totaux et d'hexanoate d'\u00e9thyle. Ceci est encore renforc\u00e9 par la \u00df-damasc\u00e9none (violettes) et une diminution des m\u00e9thoxy-pyrazines (qui peuvent masquer les caract\u00e8res fruit\u00e9s).
