Chai lovers often face discomfort due to acidity caused by common brewing mistakes. One major error is not boiling the water properly; adding tea leaves to lukewarm water disrupts the brewing process. To enhance flavor and reduce stomach issues, always boil water first before adding spices. Additionally, using too much milk can lead to digestive problems, so it's advisable to limit milk or opt for lighter tea. Another mistake is adding tea leaves too early; they should be introduced after boiling the water, milk, and sugar together. Over-boiling tea leaves increases tannin levels, which can irritate the stomach, so it's best to simmer them for just 1-2 minutes. Lastly, reheating tea can elevate acidity levels, so it's recommended to brew only what can be consumed at once.
