Why it matters
The producer
Longuich is both Schmitt Söhne’s home and the place from which its production and operations have grown. The company describes itself as one of Germany’s largest wine exporters, yet its named Mosel Rieslings still turn on the familiar Riesling exchange between residual sugar and acidity. In the Thomas Schmitt Private Collection Kabinett, 30–40 g/L of residual sugar sits beside 8–9 g/L of total acidity, making a wine that can be sweet-fruited without becoming heavy.
The modern company began in 1919, when Hilar Schmitt founded a small regional winery in Longuich. Thomas Schmitt later led its development into an internationally operating business, and Gerd Schmitt began selling the family’s German wines elsewhere in Europe. That outward movement changed the scale of the operation, while Riesling remained the grape that links the Longuich family history to bottles sold beyond the Mosel.
Place and vineyards
Where the wines begin
The Mosel is Schmitt Söhne’s base, and Riesling is its central grape. That relationship matters most in the Thomas Schmitt Private Collection, whose Kabinett is a Mosel wine and an estate-bottled Riesling. It should not be treated as the origin of every Schmitt Söhne bottle: the Eiswein comes from Rheinhessen, while RELAX Bubbles belongs to the sparkling branch of the range. The label therefore tells you which part of the company’s German wine portfolio is in the glass.
Schmitt Söhne’s US-facing material places Mosel Riesling in the region’s mineral soils. For the wines, the useful consequence is not a catalogue of vineyard names but the role of acidity: in the Mosel Rieslings, sweetness is held against a bright acid line rather than allowed to spread across the palate. Relax Riesling QbA, for example, has 7.5–8.5 g/L of total acidity alongside 38–40 g/L residual sugar.
In the cellar
Vineyards and cellar
Schmitt Söhne works from Longuich with its own Mosel vineyards and a network of growers, allowing the company to assemble a broader range than a single-site producer. That scope appears in the bottle styles: Mosel Riesling remains the family’s historic centre, but a Rheinhessen Eiswein can sit beside a sparkling RELAX wine without pretending that every bottle comes from one place.
The clearest confirmed cellar result is balance by analysis. Relax Riesling QbA carries 38–40 g/L residual sugar and 7.5–8.5 g/L acidity; Thomas Schmitt Private Collection Kabinett carries 30–40 g/L residual sugar and 8–9 g/L acidity. The Kabinett’s slightly higher acid range gives its sweet fruit a more lifted, lighter-bodied feel, while the Eiswein’s 150–190 g/L residual sugar moves toward dense, noble-sweet concentration.
Wines to know
The range in view
The range begins with Riesling but does not stop at one sweetness level. Relax Riesling QbA is the openly fruity, sweet side of the portfolio: its residual sugar brings ripe fruit and soft weight, while its acidity keeps the finish fresh. Thomas Schmitt Private Collection Riesling Kabinett is the Mosel-facing alternative, with a lighter body and a sharper acid frame around its sweetness.
Schmitt Söhne Eiswein is the concentrated outlier. From Rheinhessen rather than the Mosel, it carries 150–190 g/L residual sugar, placing it in a dessert-wine register with more weight and a richer, sweeter finish. RELAX Bubbles takes the range into sparkling wine, where mousse changes the texture and turns the fruit profile toward a more festive, chilled serve.
A useful way in
A bottle to begin with
Start with Thomas Schmitt Private Collection Riesling Kabinett. It is a Mosel, estate-bottled Riesling with 30–40 g/L residual sugar and 8–9 g/L total acidity, so it joins the company’s Longuich and Riesling roots to a clear taste experience. Expect sweet fruit, light body, lively acidity and a fresh finish. It comes before the more overtly sweet Relax Riesling or the much richer Eiswein because its sugar-and-acid balance makes the Mosel side of Schmitt Söhne easiest to taste.
