Dime Piece Brewing
1000 GPD at it's finest

We are very satisfied with this system. It provides our brewery all the purified water we need to keep making our stellar beers. We can customize the water blend for different profiles for each beer. Adding or subtracting TDS makes a huge difference in how beer comes out. We love the total control of our water.
