While sweet white wines may not be the first thing that comes to mind when you think of Bordeaux, they can quickly expand a dining palate by bringing a broad spectrum of styles, price points and food pairing versatility to the table. Bordeaux's sweet wines contribute a small, but significant 2% of the regions overall wine production.
Though, Bordeaux's sweet wine scene is dominated by its international reputation for the ultra rich, honeyed flavors of Sauternes (and Barsac) from the Graves district.
The sweet wine options from Bordeaux extend way beyond Sauternes. In fact, while Sauternes tend to snag plenty of the dessert wine limelight, with legitimate reason based on outstanding quality, sheer quantity (Sauternes comprises 43% of the region's total sweet wine production) and a high concentration of larger estates, it's the well priced sweet white wines from the other 10 AOCs that many of the Bordelais themselves tend to drink.
Sauternes and Sweet White Bordeaux Wine Regions
Bordeaux's primary sweet wine producing region is situated 20 miles south of the city of Bordeaux, spanning both banks of the Garrone River and enveloping the initial section of the Ciron River. These waterways provide the perfect backdrop for a misty morning microclimate that encourages the growth of Botrytis Cinerea, also called Noble Rot. There are 11 designated AOCs that produce sweet white wines in Bordeaux.
The most notable (and most expensive) sweet white wines of Bordeaux are Sauternes and Barsacs, yet there are plenty of less expensive, sweet wine offerings from smaller estates that bring good value bottles to the market. As an aside, the term "Sauternes" is often used to encompass all sweet wines from the Bordeaux region; however, there are technically only five villages that produce Sauternes (Sauternes, Barsac, Bommes, Fargues and Preignac), the rest are referred to as Bordeaux Supérieur AOC or simply as "Sweet Bordeaux."
Botrytis and Bordeaux Wines
The sweet wines of Bordeaux can only be made with the unique partnership of botrytis. This fungus generally forms on grapes in the fall when cool, humid mornings are followed up by warm, dry afternoons and the grapes are allowed extended time on the vine to over ripen. Botrytis changes the grape's innate composition by decreasing acidity levels and increasing the grape's sugar levels, resulting in shriveled, concentrated, raisin-like clusters. The secret to sweet Bordeaux wines is careful picking.
Since botrytis does not develop at even rates in a vineyard the harvest for sweet Bordeaux can take several months to complete. Hand-harvesters comb through the vines looking for well-shriveled grapes while tossing damaged fruit. These pickers may make up to ten passes through the same vineyard, hand-selecting only the botrytised fruit, cluster by cluster or at times grape by grape, before the harvest is finally finished. It's interesting to note that a typical grape vine produces about a bottle of wine, while an average botrytis-infected vine will only yield a single glass of wine. With lower yields, considerably more time invested in the harvest and a crop that is in the "high risk" category from weather wipe outs, it is understandable that consumers may be asked to pay a bit more for the better sweet wines of Bordeaux.
Grapes Grown for Sauternes and Sweet White Bordeaux Wines
The only grapes that may be grown in Bordeaux's sweet wine regions are Sémillon (80%), Sauvignon Blanc (15%) and Muscadelle (5%). Sémillon, which is particularly susceptible to botrytis, is the primary grape variety for sweet white wines in Bordeaux, lending deep golden color, an overall elegance and the concentrated, unctuous quality that gives the wine its heavier texture and high viscosity. Sauvignon Blanc contributes freshness and vibrant acidity along with rich aromatics. However, the Muscadelle takes the aromatics to a whole new level, bringing powerful, floral aromas to the blend.
Just How Sweet is Sweet Bordeaux Wine?
When it comes to sweet wines, it's the quantity of residual sugar in a wine that determines just how sweet the wine will be.
Residual sugar is basically the sugar from the grapes that has been left unconverted to alcohol in the final wine. In Bordeaux there are two categories of sweet: vins moelleux ("mellow" - a semi-sweet wine) and vins liquoreux, (the sweetest wines, with considerably more residual sugar). The semi-sweet moelleux wines enjoy lighter color components than the liquoreux and are characterized by more fruit and a smooth palate texture. The liquoreux wines bring more depth of color and greater intensity to the fruit, often with candied fruit components and rich honey and nut nuances. The younger wines will typically show more "fresh factor" and the older wines tend to showcase a more subdued nose, yet richer palate expressions.
Food Pairing with Sauternes and Sweet Bordeaux Wine
The sweeter style of Bordeaux's white wines enjoy a surprising breadth of food-pairing versatility, thanks to the consistent balance of acidity. From accompanying savory or spicy ethnic fare, to the classic Sauternes pairing of foie gras or Roquefort cheese, or on to an ensemble of desserts, Bordeaux's sweet wines promise to be worthy pairing partners in the midst of tricky fare, from aperitif to dessert and many things in between.
The younger sweet wines offer a fresher approach and are a natural match for the likes of scallops, salmon, poultry and even eggplant and artichoke. While the older (in the 5-10 year range) sweet wines present flavors that center around honey, apricot, spice and almonds. With more age on the wine the perception of sweetness decreases as the aromatic expressions become more subtle. These older vintages tend to match up better with fruit-based fare, almond cake, creme brulee and the like.
Top Tips for Serving Sauternes and Sweet Bordeaux Wines
The right serving temperature is critical for maximum enjoyment of Bordeaux's sweet wine selections. Shoot for a chilled temp of 45-50 degrees to best showcase the wine's aromas and palate profile. Decanting the older vintages is especially important for releasing the wine's aromas.
As an added treat, these sweeter wines will keep well for up to two weeks in the refrigerator.
