Château Guionne sits in Côtes de Bourg, the compact right-bank appellation of Bordeaux known for structured reds built on Merlot and Cabernet Franc. The estate produces two principal wines. Cuvée Renaissance blends Cabernet Sauvignon, Cabernet Franc, and Merlot into a wine that has drawn attention from Wine Spectator and Wine Advocate. The flagship Côtes de Bourg, a blend of Cabernet Franc, Merlot, and Cabernet Sauvignon, represents the appellation's character: earthy, mineral-driven reds with the grip and aging potential that define the region's best work. Both wines reflect the terroir of this historic corner of Bordeaux, where smaller parcels and careful selection yield wines of precision over scale.
