Franken is Bavaria's only wine region, bordering the Baden district of Tauberfranken to the south, with most of its vineyards situated on steep slopes along the Main. The river forms a gigantic "W" shape, with the region beginning in earnest at Aschaffenburg, reaching Würzburg at its center, and ending at Zeil am Main in the east. Würzburg is Franken's commercial center. Heavily bombed during the final weeks of WWII, the town rebuilt itself, and the famous old bridge in Würzburg's Altstadt spans the Main and offers views of Würzburg Castle and the iconic Stein vineyard (the source of Goethe's favorite wine).
Silvaner is Franken's signature variety, usually bottled in a PDO-protected Bocksbeutel, but some of Germany's finest dry Rieslings and Spätburgunders come from Franken, although grown in tiny quantities. The Rieslings and Silvaners are bone dry, sometimes to the point of austerity, which has given the rest of Germany a term for describing bone dry wines: fränkisch trocken means no more than 4 g/L residual sugar. Much emphasis was placed on Müller-Thurgau and other early-ripening or high-yielding crossings in the past. Still, producers today seem keen on leading with quality, with a clear priority shift to Silvaner, at least in Franken's quality sector.
Bavaria, especially Munich, is the world's beer capital, and while Würzburger Stein is undoubtedly famous (so much so that the term Steinwein once meant all Franken wines), a Stein of Würzburger Edelbräu is equally good, and I would suggest necessary after a full day of wine tasting. Visitors to the region might want to visit a Frankenheckenwirtschaft for some real, local flavor. These simple eating and drinking places have particular rules: vintners may sell their products to the public without a restaurant license, operate on a calendar that opens for eight weeks a year, have only 40 seats, and serve no hot food. Look for a branch cut from a Hecke (hedge) above the entrance to locate one that's open. Heckenwirtschaften aside, Franken clearly understands the importance of wine tourism, and there are many more hotels and restaurants with excellent cooking than in the relatively scant offerings in other Rheinland regions. The wine villages along the Main are charming, and Würzburg is a must.
There are three Bereiche (districts) within the Franken Weinanbaugebiet (wine region): Meinviereck, Maindreieck, and Steigerwald.
Franken's three Bereiche are based on three Triassic geological zones. Mainviereck in the west is home to Franken's (and some of Germany's) best red wines, especially from the historic Klingenberg, and the village of Bürgstadt (a sub-district known as Churfranken), where the weather is milder than the rest of Franken, and the soil base is Buntsandstein (colored sandstone). These conditions favor Spätburgunder and Frühburgunder with a lifted, aromatic profile. Weingut Rudolf Fürst is the superstar of this area with its trio of top-class Grosses Gewächs, Spätburgunder Schlossberg GG, Spätburgunder Centgrafenberg GG, and Spätburgunder Centgrafenberg Hunsrück GG. There are slate, quartzite, and gneiss soils around Michelbach and Hörstein, which favor Riesling. Both red and white wines are more delicate than in other districts. Homburger Kallmuth, a monopole of Fürst Löwenstein, is the steepest vineyard in Franken, with Bundtsandstein and Muschelkalk soils. Miltenberg is a popular town for wine tourists to explore its architecture and sample local wines.
Maindreieck is the center of Franken viticulture and is based on Muschelkalk (shell limestone), especially at Würzburger Stein. 70% of Franken wines come from this district, and 210 hectares of vines are within the city's limits. It is the driest area in the region. Steinwein has a distinctive smoky note from the soil, which deepens with time in the bottle, and three producers: Juliusspital, Bürgerspital, and Hofkeller, control most of Würzburg's viticulture. South of Würzburg are Randersacker Teufelkeller, Pfülben, and Marsberg; all feature southwestern exposures facing the river. Neighboring Frickenhausen features sandy soils and is home to the south-facing classified site Kapellenberg. Continuing upriver, the village of Sulzfeld is notable for its Maustal vineyard and outstanding producer Zehnthof Luckert. The area near Volkach and its surrounding villages is home to a high-quality co-op at Sommerach and its Katzenkopf vineyard, the grand cru Escherndorfer Lump with limestone, loess, and clay, and the Volkacher Ratsherr. By the way, the name Lump was explained to me as a Schimpfwort (an insult), "but only a moderate Schimpfwort," and why that would be the name of a vineyard, I do not know. The alternative explanation seems more plausible: as vineyard plots were divided over generations, holdings were reduced to only the size of a Lump! Silvaner is the top variety in Maindreieck, but there are excellent, bone-dry Rieslings, Weissburgunder, and aromatic varieties from this district.
Keuper defines the district of Steigerwald, which is layered along the mountain slopes. The black Keuper soil has a warming effect that aids grape ripening, even at high elevations. A concentration of classified sites lies between Rödelsee and the walled town of Iphofen, and again at Castell (the Castell family owns all the vineyards of this village, including the top site, Schloßberg), believed to be where Silvaner was first planted in Franken centuries ago. The area is home to famous sites like Küchenmeister, Kronsberg, Julius-Echter-Berg, Kalb, Casteller Schloßberg, and many top producers like Hans Wirsching, Weltner, and Johann Ruck. The black Keuper (marl with gypsum) produces wines that are more structured, flinty, smoky, and easily identifiable. Silvaner on Keuper can age magnificently, as can Silvaner on Muschelkalk. I strongly liked the Silvaners on Keuper in a recent soil-comparison tasting, especially those with 10 years or more in the bottle.
