Almost a year ago, we purchased this In-Line Dual TDS Monitor to monitor the performance of our new RO system: (http://steepster.com/teas/teaware/37798-abundant-flow-water-6-stage-alkaline-zoi-zeta-reverse-osmosis-system). This meter monitors the TDS both before and after the RO system, which is important for brewing tea:

“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

Sensor Locations:
• For monitoring the TDS level of the untreated water, the “TDS In” sensor should be installed after all the pre-filters and just before the RO membrane.
• For monitoring the performance of the RO membrane, the “TDS Out” sensor should be immediately after the RO membrane.

These two sensor locations provide the two TDS levels necessary to calculate “RO Percentage Rejection” – the parameter that determines when to replace the RO membrane (about every 3 years). See the bottom ½ of this page: http://www.tdsmeter.com/what-is?id=0003

Notes:
1. If the water in your area requires an RO system and you wish to use this water for brewing tea, a re-mineralization filter such as this (http://steepster.com/teas/teaware/39532-puregen-aptera-alkamag-water-filter) is highly recommended.
2. An additional fitting should be added to RO System that has a re-mineralization filter so the output sensor can be located either after the RO membrane for maintenance purposes, or after the re-mineralization filter to monitor the TDS of water used for brewing tea.

After using this In-Line Dual TDS Monitor for nearly a year, I’ve found it to be a simple and reliable device that provides consistent TDS data for monitoring the performance of both RO systems and re-mineralization filters. Highly recommended.

Bio

I am passionate about teas that are full-bodied, rich, & smooth. I joined Steepster to explore Multiple Infusion Teas (MITs) such as Pu-erh.

Currently, my focus is on un-flavored orthodox black & pu-erh teas. Cost-effective organic teas or teas that meet the EU Food Safety Commission Pesticide Maximum Residue Limit EUROFINS are also of interest.

I especially enjoy teas with a natural rich chocolate flavor profile as opposed to natural bittersweet cocoa.

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

Incomplete, non-specific, or cutesy instructions such as: “Just add water and enjoy.” significantly reduces the possibility that I will purchase that particular tea.

Having to discover the optimum brewing parameters through “trial & error” is too time-inefficient, wastes valuable tea and impairs the progress and joy of tea exploration.

The best tea suppliers evaluate each crop / batch of tea each year to determine the optimum brewing parameters. This insures the best possible first impression of their tea, greatly increases customer satisfaction, and thus increases word-of-mouth advertising – the best form of advertising that money can’t buy. You never have a 2nd chance to make an Outstanding First Impression.

My wife is an Earl Grey Fan. We enjoyed Twinings for many years – mostly Earl Grey, also English/Irish Breakfast, & Prince of Wales. Several years ago, TEG no longer tasted as good.

Rishi EG & China Breakfast then became our regular teas. However, after winning Tea Expo awards, the prices kept rising.

Our most recent orders were from TeaVivre, Verdant, Zen Tea Life, & Mandala Tea. Kudos to Angel Chen, David Duckler, Kenneth Son, Garret Sorensen who have been extremely helpful.

High quality water is essential for excellent tasting tea.
