Rolly Gassmann

At A Glance

Rolly Gassmann is an Alsace AOP domaine in Rorschwihr, where its family wine roots reach back to 1611. Pierre Gassmann now runs 51 hectares with a ten-person team, drawing fruit from Rorschwihr, Rodern and Bergheim. The range is large—40 wines each year—but its organising idea is concrete: hand-picked parcels, separate fermentations and time on lees before release.

The Producer

The Rolly Gassmann name joins two winegrowing families. Pierre Gassmann, son of Marie-Thérèse Rolly and Louis Gassmann, is the current proprietor, with Rorschwihr as the domaine’s centre of gravity. A bottle labelled by grape, such as Riesling or Gewürztraminer, sits alongside wines named for Rorschwihr lieux-dits: the first foregrounds variety, while the second narrows the address to a named vineyard site.

Place

Rorschwihr lies in Alsace, and the domaine’s Alsace AOP vineyards extend south and north into Rodern and Bergheim. That three-village footprint supplies grapes for both broad varietal bottlings and more tightly located wines such as Kappelweg de Rorschwihr Riesling, Pflanzerreben de Rorschwihr Riesling, Weingarten de Rorschwihr Sylvaner, Moenchreben de Rorschwihr Auxerrois and Moenchreben de Rorschwihr Muscat.

Soil And Site

Rorschwihr contains 21 recorded subsoil types, predominantly limestone. Rather than gather these sites into a single cellar blend, Rolly Gassmann keeps plots apart from harvest through fermentation. The result is a range in which a Rorschwihr lieu-dit can remain a named wine, with its own pressing and fermentation schedule, rather than disappearing into a generic Alsace label.

Story

Generations of the family worked as independent winegrowers and harvesters in Rorschwihr before the present domaine took shape. The long family connection has not made the cellar static: 51 hectares across three villages require a working method able to hold many parcels apart. Pierre Gassmann’s estate therefore makes 40 wines annually, from grape-labelled bottles to named-site wines and sweet Sélection de Grains Nobles.

The domaine works with organic and biodynamic approaches, though it holds neither organic nor biodynamic certification. In the vineyard, every plot is hand-harvested; in the cellar, each is vinified separately. Those choices keep the origin of a Riesling, Gewürztraminer, Sylvaner, Pinot Gris, Auxerrois or Muscat visible in the finished range.

Vineyards And Cellar

Local yeasts ferment the parcel wines naturally, taking four to six months according to terroir. For the documented varietal group, grapes may be pressed for up to 12 hours and ferment for four to five months; individual lieux-dits receive 12 to 15 hours of pressing and six months of fermentation in large oak barrels. Longer pressing and fermentation give the site wines a different cellar course from the varietal tier.

Large old oak barrels and stainless-steel tanks both appear in the cellar, followed by ageing on fine lees. Every wine receives at least 11 months of ageing, and many remain in cask or tank until the September after harvest. The hillside winery known as La Cathédrale has six levels, allowing grapes, must and wine to move by gravity as each parcel follows its own path through the building.

Wines

The varietal wines—Riesling, Gewürztraminer, Sylvaner and Pinot Gris Réserve—form one clear part of the portfolio. They are made to show their grapes, with fine-lees ageing and, in some cases, residual sweetness balanced by fine acidity. This is not a range confined to dry white wine: sweetness is a structural element, while acidity keeps weight and fruit from settling heavily on the palate.

The lieu-dit bottles take the range further into named Rorschwihr sites, with longer pressing and oak-barrel fermentation. Sélection de Grains Nobles Riesling and Gewürztraminer occupy the sweet-wine end of the portfolio. Across these categories, bottle age matters: the estate states that some wines can develop for 20 to 50 years, with aroma and acidity increasing in intensity over time.

In The Glass

The 2019 Gewürztraminer opens with jasmine and exotic fruit, then turns rich across the palate before finishing fresh and saline. Gewürztraminer supplies the floral, expansive fruit character; its long fermentation and lees ageing place that perfume on a fuller-textured wine rather than a simple aromatic white. The saline finish brings a dry-edged sensation after the richer middle.

Rolly Gassmann’s 2016 Pinot Gris is full-flavoured and medium/off-dry, with butter and toffee in its profile. Here the residual sweetness adds body and roundness, while Pinot Gris carries the wine’s broad, savoury weight. It is a useful contrast to the Gewürztraminer: less floral, more buttery, and shaped around texture rather than jasmine perfume.

A Bottle To Understand It

Start with Rolly Gassmann Gewürztraminer 2019. It is a grape-labelled Alsace wine with jasmine, exotic fruit, a rich palate and a fresh saline finish, so its flavour is easy to recognise while its structure shows the domaine’s slower cellar work. The wine’s extended fermentation and ageing on fine lees place floral fruit beside body, acidity and a lingering saline close.

Anecdote

In 1967, Marie-Thérèse Rolly married Louis Gassmann. Both came from winegrowing families in Rorschwihr, and the marriage brought their two family traditions into one domaine carrying both names. The couple ran the business together with their second son, Pierre, who is now the proprietor. The event sits behind every Rolly Gassmann label: a family name formed by a marriage in the village where both sides had already worked vines for generations.

Final Word

Rolly Gassmann is most useful when approached as a cellar of distinct Alsace wines rather than a single house style. Begin with the floral, saline Gewürztraminer, then follow the labels from grape to named Rorschwihr site; the hand-picked parcels, long fermentations and lees ageing explain why the bottles move from bright aroma to fuller texture and long finish.
