Our Founder’s Block Chardonnay comes exclusively from this historic block and includes our Proprietary Chalk Hill Clone 97 Chardonnay, which was developed in partnership with UC Davis between 1996-2001. During this time, Chalk Hill conducted one of the largest and longest maintained Chardonnay clonal trials in California and in doing so cemented its legacy as a producer of luxury Chardonnays. Chalk Hill is the only vineyard to grow this clone, so it is truly a one-of-a-kind Chardonnay.
