The 2018 Chardonnay La Source comes from old vines on an east-facing slope at the bottom of the hill (Summum comes from the vines at the top of the hill). Its aromas of struck match and flint take time to open to golden apples, baklava and floral perfume. The medium-bodied palate also begins minerally, bright and fresh but broad and hinting at more to come. Give it another couple years in bottle.
