Tönissteiner Zitrone Fit soft drink

Tönissteiner is a historic German brand of mineral water and fruit-based beverages. The brand originated from the Tönissteiner Sprudel, which claims to be Germany's oldest carbonated mineral water spring, used since Roman times in the Brohl Valley. The 'Zitrone Fit' line featured in the image is a low-calorie sparkling lemon fruit juice drink that leverages their natural mineral water base.

The brand is owned by Privatbrunnen Tönissteiner Sprudel C. Kerstiens GmbH, a family-owned company. Unlike many major beverage brands that have been acquired by global conglomerates, Tönissteiner remains an independent medium-sized enterprise. The production is concentrated in Bad Tönisstein, Germany, where the water is sourced and the drinks are bottled, ensuring high quality and adherence to traditional standards.
