You may hear Lu Yu called Tea Saint and his tea scripture. Tea scholar Lu Yu lived in the Tang Dynasty. He was a poet, a historian and an artist. In his tea scripture, he wrote the perfect water for brewing tea was from the center of a swiftly moving mountain stream. However, nowadays, we cannot easily have access to this perfect type of water, because it is very difficult to find the water resource. We are busy and our environment has been polluted. Therefore, we need to consider some other options to get ideal water for brewing tea. We can get several types of water. Here are their pros and cons when it comes to tea brewing.
Mostly, the ph of water is over 7. This means it may contain many minerals that make water take on unwanted flavor. Therefore, you’d better use a filter to purify it before brewing.
Well water is not the perfect water for direct using to brew tea due to its higher pH. It is recommended to test your water and if the PH is above 8.5, the water is very hard and you need to use a water filter to filter it or to use a water softener to make it soft enough.
After boiling the filtered water, you also can smell minerals, meaning it is too hard to cook tea.
If your tap water is low quality, you may consider buying bottled water to cook tea. Don’t buy mineral water because it is too hard to make your tea taste harsh or metallic. On the other hand, distilled water is also not suitable because it is too soft to make your tea taste flat.
Another choice is high quality spring water. When choosing one, some types may be much better than others. The ph of spring water should be around 7 and water should be in flavor. TDS (Total Dissolved Solids) content should be less than 30 PPM (parts per million).
When it comes to choosing between spring water and filtered tap water, you also need to consider the environmental impact and the cost. If the filtered water from your home water filtration system is as good as bottled spring water, it is highly recommended to use tap water, saving you much money and reduce the impact on our environment.
The most common type of water we can easily access is the tap water. Although it may be low quality, we can use a water filter to get high quality filtered water. Besides fresh mountain stream water and high quality bottled spring water, high quality filtered water is also perfect for brewing tea. In some areas, the tap water is too good to not be filtered.
If you find your tap water is very hard, you may need to install a whole house water softener to soften your water first and then use an under sink water filter to purify your water furthermore. This is because hard water is bad for tea brewing. Or you also can consider buying bottled water if you don’t want to invest in such a water softener and a water filter.
