The best water makes the best-tasting tea
The best tea is made with the best water
✅ Spring Water
✅ Tap Water
⛔️ Reverse Osmosis
Since half of tea flavor is water, it's important to check your water quality. One of the most common causes of weak or bitter tea is reverse osmosis water or distilled water. This is because tea flavor is created by tea leaves bonding with minerals in the water. If there aren't enough minerals in water to bond with, there won't be much flavor.
You may not know that the water in your tap is filtered or reverse osmosis. This is because some buildings have a water filtration system. Some towns use reverse-osmosis processing at their regional water plant.
For the best, brightest tea flavor, we recommend bottled spring water. Filtered water, and in many case tap water, also make great tea. Another thing that may affect tea flavor is residue from cleaning products. Scented dish detergent will leave a scent on mugs, cups, and pots.
Taste the difference for yourself:
Set up a side-by-side taste test. Using the same amount of the same tea, at same water temperature brew one mug with distilled water (Smartwater) or reverse osmosis water (Dasani) and the other mug with spring water or tap water if you're sure it's not filtered.
