Check out affordable substitutes for scarce Sancerre

Other parts of the Loire Valley. You can hit on a substitute that is very close to Sancerre by exploring the adjacent areas in the Loire that also produce quality sauvignon blanc. Wines from Touraine frequently will give you an exceptional value — there are several small producers there taking great care to make quality wines at a Tuesday night price. A favorite is Domaine Tardieux-Gal Touraine sauvignon blanc. Mossy minerality, an opulent taste of citrus and great acidity make this a beautiful substitute for Sancerre, for around $20 retail.

Other regions of France. Head south from the Loire to Bordeaux to discover France’s other exciting region for sauvignon blanc. This area is well-regarded for robust, age-worthy red blends, but also has some exceptional sites for white. Graves is a sub-appellation for excellent white wines from the area, thanks to limestone clay soils that translate to a pleasant minerality. These wines generally are blends, with sauvignon blanc joined by sémillon and muscadelle. Chateau Graville-Lacoste Graves blanc, for example, is a great value, for under $25.

California. Sonoma County is the perfect spot to seek out a domestic alternative to Sancerre, as the cooling Pacific breezes and fog help temper the California sunshine. With slightly more tropical fruitiness and a bit more texture, thanks to time spent resting in oak, Maitre de Chai sauvignon blanc is a delicious option for those who prefer the more opulent style of sauvignon blanc.

South Africa. This region in the Southern hemisphere still is not getting enough credit for the quality of its white wines. A diversity of soil types, including ancient sandstone, shale and clay, makes it great territory for vibrant sauvignon blanc. Kumusha makes sauvignon blanc from a few vineyard sites, but its Western Cape variety is crisp and refreshing — and a steal for around $15.
