Quellbrunn Naturell Mierbachquelle mineral water

Quellbrunn is a well-established private-label brand for mineral water and soft drinks, primarily sold at ALDI Nord and ALDI Süd supermarkets in Germany. This specific product, identified as 'Naturell Mierbachquelle,' originates from the Mierbachquelle spring located in Breuna, Hesse.

The Quellbrunn brand has historically been sourced from various regional mineral springs throughout Germany, including the Brandenburger Urstromquelle and Kurfels-Mineralbrunnen, to ensure local distribution and reduce transport distances. In late 2022, a significant shift in ownership occurred when the ALDI group (specifically ALDI Nord) acquired several key production sites from the Altmühltaler Mineralbrunnen Group. This acquisition integrated the bottling operations into ALDI's own supply chain, making the retailer both the brand owner and, in many cases, the direct manufacturer/bottler for its water category.

As of 2026, the brand remains under the ultimate ownership of the Albrecht family through ALDI. The product is manufactured and bottled in Germany, adhering to strict national mineral water regulations.
