The present technology provides a method for preparing an acid-reducing filter that includes depositing a mineral blend layer to a filter substrate, where the mineral blend layer comprises calcium carbonate and magnesium carbonate at a weight ratio of about 1:10 to about 10:1, the mineral blend is free of soluble halide or hydroxide salts of alkali or alkaline earth metals, and the mineral blend layer is insoluble in water.

The present invention relates to an infusion product for making a beverage, more specifically to a plant-based composition for making a beverage, and to a herbal and/or vegetable composition or bouquet garni. The plants are fruits, herbs, medicinal plants, tea, vegetables and/or spices. The invention further relates to a method for producing said compositions or infusion product, its use for making a (tea) beverage, and a (tea) beverage so obtained. Further, the present invention relates to a fiber-web, preferably a tea bag, made from said fruits, herbs, medicinal plants, tea, vegetable and/or spices.
