For heavily pigmented and big reds. Good mid-palate fullness and color & flavor stability. Ferments high sugar musts low in nitrogen and high polyphenols. It is a rapid starter with moderate fermentation rates. This strain is able to bring out differentiated varietal aromas by bringing out the rich concentrated flavors found in varietals such as Syrah and Zinfandel, but also enhances less aromatic varietals such as Petit Syrah. Good for mature ripe grapes.

  • For Zinfandel, Syrah & Petite Syrah

P7Y9 is popular for barrel-fermented Chardonnay, as a base for blends and for classic white Burgundy. Known for its slow, steady fermentation, especially at cold temperatures, P7Y9 produces a balanced flavour profile and rich, full mouth-feel. Pineapple and floral notes are joined by development of fresh butter, toasted bread, honey, hazelnut and almond when aged on the lees. Wines produced with P7Y9 are wonderful as-is for that classic white Burgundy, or can serve as a great foundation for blends.

P1Y2 is an excellent choice for full-bodied, complex and delicate varietals such as Pinot Noir. Color and structure are maintained throughout fermentation and aging. This yeast produces smooth Pinot noirs with ripe berry, bright fruit, pepper and spicy characteristics. It is also highly recommended for lighter red varietals where color and tannin stability are desired. P1Y2 works well with both young and aged red wines.

PY522 is most similar to Montrachet (UCD522) and is designed for traditional white Burgundy style and full-bodied red wines. A strong fermenter with moderate tolerance for alcohol and free sulfur dioxide. Low acidity. Good flavor complexity and intense color.
