Updated: Aug 31, 2022

The German independent testing institute and publisher 'Stiftung Warentest" tested 32 classic mineral waters conclusion: water from German supermarkets is usually good.

They provided the grade “very good” eight times, including the 6 discount retail brands from Lidl, Penny, Rewe, Norma, Aldi Süd and Aldi Nord.

The 6 German Discounter brands:

  • Lidl Saskia Classic (Source Läningen)

  • Penny Classic ("Forest Source")

  • JA! Classic ("Quintus Source")

  • Aldi Nord Quellbrunn Classic

  • Aldi Süd Quellbrunn Classic

  • Norma Surf Classic

The 2 German national brands:

  • Vilsa Naturfrisch Classic

  • Aquintus Classic

The mineral water from discounters Lidl, Penny, Rewe and Aldi usually costs 0.25 euros (US$ 0.27) per 1.5 liter PET bottle, which corresponds to the already mentioned liter price of around 0.17 euros (US$ 0.18)

Well-known national branded products such as Gerolsteiner, San Pellegrino, Residenz Quelle and San Benedetto scored "good". However, they are also very expensive at around 0.50 euros (US$ 0.53) per liter.

Some time ago, 'Stiftung Warentest' also examined butter, a discounter product was one of the test winners.
