Gebrüder Loosen (“Loosen Brothers” in German), is the winemaking company that produces the range of Dr. L wines. It is owned by Ernst Loosen, who also owns the Dr. Loosen estate, and is managed by his younger brother, Thomas. Together, the brothers work with small growers throughout the Mosel region to source fruit for the wines, which are vinified by the same highly skilled cellar team that produces the Dr. Loosen estate wines. Very strict quality standards require that the growers improve their viticulture in order to sustainably grow the healthy, perfectly ripe fruit that Ernst and Thomas want for these wines.
