Constellation Brands has introduced the first offering in a new luxury tier from Kim Crawford, the leading New Zealand wine brand. Kim Crawford Signature Reserve Sauvignon Blanc ($25 a 750-ml.) is made from grapes from the lower Wairau sub-region in Marlborough, and each vineyard parcel is fermented separately in small batches. The wine has rich notes of tropical fruit, a crisp minerality, and a clean finish. The wine is now available nationwide. For more information, visit Kimcrawfordwines.com.
