What is the grape variety primarily used by Peller in their "Ice Cuvée" sparkling wine?

Peller Estates, a well-known winery in Canada, produces their "Ice Cuvée" sparkling wine primarily using Chardonnay. This grape variety is renowned for its versatility and ability to contribute finesse, elegance, and a vibrant acidity, which are essential characteristics for high-quality sparkling wines. Chardonnay is often used in the production of traditional method sparkling wines, as it can impart flavors of green apple, citrus, and sometimes creaminess depending on the winemaking techniques employed.

While other grape varieties can be used in sparkling wine production, such as Pinot Noir, which is also part of the blend in many prestigious cuvées, Chardonnay stands out in Peller’s "Ice Cuvée" for its foundational role in the wine's profile. The choice to focus on Chardonnay aligns well with industry practices, especially in cooler climates, where this grape can thrive and produce exceptional results, making it the correct answer for this question.
