If your tap or well water has impurities that must be filtered out such as high levels of hardness, or iron that necessitate a water softener and you then wish to remove the sodium introduced by the softener (because you have high blood pressure or a family history of high blood pressure) or, if there are any number of contaminates, a reverse osmosis system is frequently necessary. However, RO water is not the best for brewing tea:

“Putting aside for a moment the influences on tea before it is dried and finished, tea also goes through a second “flavoring” process as you brew it and sip it. First, you have to consider the water you use, and take into account all the flavors it offers. Straight reverse-osmosis water is never recommended in tea brewing, because it is so pure that it tastes flat. If you use a spring water or filtered tap water, the flavor of this water will come through, contributing sweetness, texture, or in undesirable cases, metal and chemical traces to your tea. No matter what, you are “blending” your tea with a water that you hope will help bring out the best that the tea has to offer.”

If an RO system is necessary for your residential water and you want to enjoy your tea without hauling bottled spring water, then you may wish to consider adding a re-mineralization filter after your RO system such as the Aptera to bring your TDS level into the following range:

“Water with 50 – 150 ppm total dissolved solids (TDS) or 1 to 3 grains hardness provides the best results, according to the Tea Association of the USA." http://www.teaandcoffee.net/0609/tea.htm

During the past 11 months the TDS of our RO water, measured before the Aptera, has typically been ~26 PPM.

Within the past week, we now have the ability to use our HM Digital: DM-1: In-Line Dual TDS Monitor (http://steepster.com/looseTman/posts/191077) to also monitor how much the Aptera is able to raise the TDS level after being filtered by our reverse osmosis system. Today for example, the TDS level after the Aptera filter is 86 PPM, which puts us right in the middle of the 50 to 150 PPM range recommended by the Tea Association of the USA. I plan to track this metric over time.

Please be advised, that a number of factors affect how high a re-mineralization filter like the Aptera will raise your TDS including: age of filter, water pressure, water temperature etc. As they say, “YMMV”.

Highly recommended based on the taste of both our water and our tea.

Update 10/27/17:
Today, I sanitized our RO system and replaced all the filters (routine RO system maintenance). We upgraded from the Puregen Aptera Alkaline Filter to the Zaria Everest Alkaline Water Filter:

The major difference is the Zaria Everest is NSA-certified, the Puregen is not.

My wife and I enjoy shou that:
- is Full-bodied, thick, rich, creamy smooth
- produces a full-mouth feeling with a long pleasing finish
- w/o obvious acidity, astringency, or bitterness
- Retains this profile & is complex enough to enjoy for multiple steeps

Notes of interest:
- natural rich chocolate (as opposed to too bittersweet cocoa)
- honey, caramel, stone fruits, sweet potato, barley, fresh baked bread

Notes not of interest: Floral, vegetal, woody.

Cost-effective organic teas or teas that meet the EU Food Safety Commission Pesticide Maximum Residue Limit EUROFINS are greatly appreciated. Many people drink tea for the anti-oxidant health benefits. So why would health conscious tea lovers drink tea that contains pesticide residues?

Complete steeping instructions on the bag are greatly appreciated:
tsp. (g) / oz. / temp. / rinse? / min. for both Western & Gongfu brewing.

Our recent orders have been from: Yunnan Sourcing, King Tea Mall, Whispering Pines, & Arbor Teas. Kudos to them as they have all been extremely helpful.

Our cupboard doesn’t include the many greatly appreciated samples generously provided by Steepsters’s favorite tea suppliers and by several very kind Steepster members.

Current Gogng Fu Brewing Method:
20g / 6 oz / 205° / 60s preheat / 60s warm leaves / 5s rinse / 5 min rest / 5s / 5 / 7 / 10 / 15 / 20 / 25 /30 / 45 / 60. Every two steeps combined in a sharing pitcher.

High quality water is essential for excellent tasting tea.
Our 450’ well provides hard water. For details see: http://steepster.com/looseTman/posts/176233#comments.
