Gouais blanc

Gouais blanc is far more important as a parent than as a bottle on a shop shelf. Also known as Heunisch, this old white grape contributed to the ancestry of numerous European varieties, including Chardonnay and Gamay. Its history helps explain how very different wines can be connected through the same modest vineyard grape.

The variety itself largely disappeared from commercial production as other grapes became preferred. Surviving plantings and conservation work therefore matter for heritage as well as for drinking. A rare varietal bottle should be approached as a chance to taste that heritage, rather than as a guaranteed substitute for one of its more celebrated descendants.

If you find a producer offering it, read the actual wine description carefully: the grape's family tree says little about an individual bottling's flavour or sweetness. A comparison with Chardonnay can be instructive, but the purpose is to notice difference, not to prove that the parent tastes like the child. Availability will usually be the biggest buying constraint.
