Position
Marcobrunn covers 7.1 hectares in the Hessian cultural landscape register, 6.67 by the shareholders' own accounting, on the right bank of the Rhine between Erbach and Hattenheim. End to end it measures some 700 metres, following the old country road that joins the two villages, on the Strahlenberg above the old federal road, with a railway line cutting straight across the middle. The site lies at 90 to 100 metres above sea level on a gradient of 5 to 19 percent, facing south toward the Rhine, planted exclusively to Riesling.
Two of Erbach's other classified sites meet it. The Schlossberg, about six hectares, begins directly above Schloss Reinhartshausen and runs west toward Hattenheim until it reaches Marcobrunn. The Siegelsberg, often called Marcobrunn's little brother, adjoins as well and sits above the Schlossberg at about 100 metres on a 16 percent slope. The rest of Erbach's classified vineyards are not borders at all, only near neighbours: Hohenrain (110 metres, 15 percent, southwest facing) and Steinmorgen (90 to 120 metres) sit close to the town on either side of the road to Kloster Eberbach, Michelmark lies further out, and Honigberg, the village's largest Einzellage by area, runs just below the forest edge above.
That geography inverts the usual logic of Rheingau greatness. Marcobrunn is the site nearest the river and the lowest band of the classified slope; every one of its neighbours reaches higher. What it is not is gentle. Its steepest rows, at 19 percent, are steeper than anything in the Siegelsberg or the Hohenrain. Altitude gives Marcobrunn nothing. Its advantages are the Rhine a short way below and what lies underneath.
Marl Under Loess
Tertiary marl sits at the bottom of the profile. Above it lies a thick loess loam flecked with mica, and across parts of the site the whole column turns sharply limy. Kloster Eberbach, which farms 1.7 hectares here, describes its parcel as loess over calcareous clay marl and puts the gradient at up to 25 percent, steeper than the 5 to 19 percent recorded in the Hessian register, which is the figure to trust for the site as a whole.
Marl is the operative word, but the water arrives from further away than the topsoil. Marcobrunn is grouped with the Hattenheimer Wisselbrunnen and the Hattenheimer Nussbrunnen as the Rheingau's Brunnenlagen, the spring sites. They are not contiguous, and they do not border one another. What links them is plumbing rather than adjacency: dense rock strata descend out of the Taunus and pass beneath these riverside parcels, delivering rain that fell well above them into the vineyard soils. That is the mechanism behind the water supply the regional description credits for the site's quality: the vines are fed even in hot, dry years.
The result is the opposite of the Mosel's arrangement, where a few centimetres of weathered slate starve the vine into weightless, piercing wine. Marcobrunn has a reservoir. Its clay-rich, lime-bearing subsoil holds water, the loess above it feeds a vine generously, and the calcareous fraction supplies an acid spine that keeps the resulting weight from going slack. Where slate concentrates by deprivation, Marcobrunn concentrates by ripening fully without ever running dry.
The Wine
The consequence is a Riesling that runs against the German stereotype: full-bodied, broad across the palate, built on ripe orchard and yellow stone fruit rather than lime and slate smoke. The texture sits closer to cream than to cut, and the mineral register reads savoury rather than smoky, which is the marl showing through. The best examples are powerful without being heavy. The regional description stresses both the site's Rassigkeit and its long cellar life. A joke current among local tasters sets the bar for expertise at telling apart the rows above the railway line from the rows below it.
The reputation is old and specific. Rheingau vineyard names first appear in the 1211 property register Oculus memorie, as marks of ownership rather than origin; Marcobrunn is listed as a site by 1390, its wine already traded as a quality wine. In 1576 the Protestant Duke Erich of Braunschweig-Lüneburg ordered two Stück of Marcobrunner by name, adding that if none could be had he would take a wine of equivalent quality. In 1726 Marcobrunn became the first Rheingau vineyard used on a label to designate a wine, and it appeared there with no village attached. Until the second half of the nineteenth century the label read Marcobrunner and nothing more; only then did pairing a site with its parish harden into convention. Erbach's possessive was a late addition to a name that had managed without one for 150 years.
Dünkelberg's Der nassauische Weinbau of 1867, the first classification of Rheingau vineyards, ranked it first class. Thomas Jefferson passed the site in 1788; Goethe, who came through by carriage in 1814, counted Marcobrunner among the Magnaten, the top wines he considered beyond ranking against one another; Fontane, writing to Theodor Storm in 1854, made a bottle of it the thing that lets the heart absorb a blow. In 1883 an 1868 Schönborn Marcobrunn Beerenauslese was poured for Kaiser Wilhelm I at the dedication of the Niederwalddenkmal. It reached the table declared a Rüdesheimer instead, a substitution nobody could call illegal, Germany having no wine law at the time. Today the site holds VDP.Grosse Lage status and the dry wines are bottled as VDP.Grosses Gewächs.
In 1810 the citizens of Erbach enclosed the spring at the Gemarkung boundary in neoclassical stone, a semicircular niche set into the vineyard wall behind four fluted sandstone pilasters, and carved their claim into the Erbach face: MARCOBRUNNEN GEMARKUNG ERBACH. Hattenheim replied in verse on the other side: So ist es richtig und so soll es sein. Für Erbach das Wasser und für Hattenheim den Wein. The fountain was restored in June 2014 and tagged with graffiti before it could be unveiled. It still straddles the line. Erbach kept the vineyard designation; Hattenheim kept the joke.
Who Farms It
Seven estates hold the 6.67 hectares. Schloss Schönborn has the biggest block at 2.20 hectares, roughly a third of the site, and the vines standing on it are reckoned the oldest in Marcobrunn; the parcel reached the house of Schönborn by inheritance in 1673 and 1684 from Georg Anton von Heppenheim genannt vom Saal. Paul Graf von Schönborn closed the estate's cellar operation in January 2021 and leased his top sites to Künstler of Hochheim, who has farmed the Marcobrunn rows and the Hattenheimer Pfaffenberg monopole since that vintage.
The Hessische Staatsweingüter of Kloster Eberbach hold 1.70 hectares. Schloss Reinhartshausen holds 1.05; Princess Marianne bought that estate in 1855 for 275,000 gulden and it stayed with her Hohenzollern descendants until 1987. Weingut Höhn holds 0.40, von Oetinger 0.12 from an Erbach family growing here since 1828, Baron Knyphausen 0.10 from the Draiser Hof the family acquired in 1818 and now farms under full organic certification from the 2021 vintage, and Balthasar Ress 0.06.
More names appear on labels than there are shareholders, because the rows change hands without the deeds moving. Corvers-Kauter works parcels that belonged to Langwerth von Simmern, an estate founded in 1464, as part of a long-term lease of 15 hectares that also takes in Hattenheimer Nussbrunnen and Rauenthaler Baiken; it has managed the vineyards since 2018, in organic conversion from that year and certified from 2021. Langwerth von Simmern bottled its last vintage under the family name in 2016, left the VDP at the end of 2017, and wound the estate up in 2018. Weingut Prinz of Hallgarten also bottles an Erbach Marcobrunn Grosses Gewächs, from a clay-rich parcel above the railway line, beginning with the 2021 vintage.
Two of the site's most storied proprietors thus left winemaking within four years of each other, and their rows are now farmed by tenants. The stone at the spring has outlasted both.
