The Shy Susan Chardonnay 2019 from Tasmania is a specific bottling, often associated with Billy Button Wines, known for its cool-climate Tasmanian fruit, offering notes of toasty/buttery notes with wet stone, highlighting quality Tasmanian Chardonnay with potential for aging, though it's generally best consumed within a few years, making the 2019 a mature but still enjoyable expression if stored well, especially given its high-quality vineyard source.
