ja! Quark

ja! is a well-known private label brand belonging to the REWE Group, one of Germany's leading retail companies. Launched in 1982, it was designed as a budget-friendly discount brand to compete with hard discounters like Aldi and Lidl.

The ja! Quark is manufactured by various German dairy suppliers on behalf of REWE. Production sites often vary by region and contract, but typical manufacturers include large dairy cooperatives such as DMK (Deutsches Milchkontor) or Molkerei Jakob Berz AG, identified by health marks like DE NI 010 EG or DE HE 007 EG on the packaging. The product is fundamentally a German staple, deeply rooted in the local food retail landscape and owned by the Cologne-based REWE Group.
