They taste like two different products. The first cup is dull, a bit astringent, and sometimes cloudy on the surface; the second is clear, fragrant, and bright. In our guides on brewing techniques, we always mention water briefly. It was time to dedicate the comprehensive feature it deserves\u2014from the most delicate green tea to an evening herbal tea.<\/p><section id=\"calcaire\"><h2 style=\"margin: 38px 0 16px; color: #2d3a2f; font-size: 26px; font-weight: 800; letter-spacing: -0.02em;\">1. Limescale: France\u2019s No. 1 enemy<\/h2><p>Visit <dfn>water hardness<\/dfn>, which is its content of dissolved calcium and magnesium\u2014in other words, limestone. It is measured by the <abbr title=\"hydrotimetric title\">TH<\/abbr>, expressed as <abbr title=\"French degrees\">\u00b0F<\/abbr>&nbsp;: One French degree corresponds to 10 mg of calcium carbonate per liter. The thresholds vary slightly from one source to another, but the standard scale is clear: below 15 \u00b0f, the water is considered soft; above 25 to 30 \u00b0f, it is hard. Much of France (the Paris Basin, the North, the East, and the Mediterranean coast) falls in the upper half of the scale; Brittany, the Massif Central, and the Pyrenees are better off.<\/p><p>Why is this a problem for the infusion? Because excess minerals come between the water and the tea leaves: extraction is less thorough, the volatile aromas are stifled, and the bitterness becomes more pronounced. With black tea, hard water even forms a thin, iridescent film on the surface of the cup\u2014perfectly harmless but unappealing. Not to mention the limescale that builds up in the kettle with every use.<\/p><div style=\"margin: 16px 0 0; padding: 14px 18px; background: #f7f6f0; border-left: 3px solid #c8a46a; border-radius: 0 12px 12px 0;\"><p style=\"margin: 0; font-size: 15px; line-height: 1.7;\"><strong style=\"color: #2d3a2f;\">What changes in the cup:<\/strong> Muted aromas, more pronounced bitterness, and a film on the surface of black teas. <strong style=\"color: #2d3a2f;\">How can you tell:<\/strong> Water hardness is often listed on your water bill or your water utility\u2019s website, and the test results for each municipality are published by the Ministry of Health.
