The Water Temperature Debate

Mastering water temperature is the most technical aspect of mate preparation, with the ideal range tightly held between 75-80°C. Using boiling water at 100°C burns the yerba, releasing excessive tannins that overwhelm the flavor—a common mistake that ruins 90% of first brews. In contrast, water below 65°C fails to extract enough caffeine and nutrients, making the mate weak. Local aficionados gauge temperature by eye, noting when small bubbles form at the bottom (around 75°C), a datapoint that beginners must learn. This balance ensures a smooth, rich taste that lasts for up to 10 refills.
