This 2021 Porongurup Chardonnay from Castle Rock Estate is likely to exhibit a vibrant and elegant profile, characteristic of cooler climate Chardonnays. Expect aromas of crisp green apple, citrus (lemon zest, grapefruit), and perhaps subtle notes of white peach or nectarine, often intertwined with a delicate minerality and a hint of flint. On the palate, it should be refreshing with bright acidity, a medium body, and a clean, persistent finish. Depending on winemaking, there might be a whisper of well-integrated oak imparting subtle nutty or creamy undertones, but typically Porongurup Chardonnays emphasize fruit purity and natural acidity.
