Happy St. Patrick's Day from ProChem, Inc.
Beer tastes better when it's made with RO water.
Breweries source their water just like any other manufacturer: from the city supply. That water is drinkable, of course. However, the taste isn't pure. To brew a beer with just the right taste that's true to the hop, you need to start with highly filtered water. Reverse Osmosis is the best way. And that green beer, well, the food coloring is manufactured using treated water too. #watermatters
