re·verse os·mo·sis (rĭ-vûrs′ ŏz-mō′sĭs, ŏs-)

A technique for purifying water, in which pressure is applied to force liquid through a semi-permeable membrane in the opposite direction to that of normal osmosis.

Great beer is only as great as its ingredients.  Grain, hops, yeast and water, all must be of the highest quality to ensure high quality beers.  Since beer is mostly water, it makes sense that the water used in making the beer is of the utmost highest quality and purity.  Reverse Osmosis (referred to as RO) water treatment is one of the most effective and thorough methods to effectively remove undesirable additives and other contaminants from a water supply.  The RO process is particularly effective in removing chlorides, dissolved solids and fluoride from the water supply.   Fluoride, for example, is not removed by traditional paper or charcoal filters and is concentrated in the brewing process if not removed.

The team at Trap Door Brewing is committed to serving you the highest quality beers.  We carefully craft our beers using the finest of ingredients including:  locally sourced grains from Great Western Malting in Vancouver WA, Yakima and Willamette Valley hops, yeast from local sources, and Reverse Osmosis water produced onsite.   Our processes ensure you get consistent, quality beer in every glass, pint, growler, and keg.
