- ☑️【 WHAT IS TDS 】TDS = Total Dissolved Solids, which is any salt, metal or mineral in the water. The lower the TDS level in the water, the more efficiently your bodys cells can use the water. Conversely, higher TDS levels can indicate water that is more difficult for your body to use and has more contaminants that can pose health risks.
TDS meters can are helpful for brewing if you’re using a RO filter or if you purchase RO (reverse osmosis) water for brewing. If you’re using an RO filter a TDS meter tells you how effective your filter is and can help you know if your filters need to be replaced. If you buy RO water, a TDS meter can let you know what you’re getting as some water processors add minerals back for flavor. A TDS meter will allow you to make sure you’re getting what you want.
RO water can be built up to reflect the exact water profile you’re looking for. See: Water by John Palmer and Colin Kaminski
