Sustainable Microbreweries, Inc. holds the value of water as a human right and furthers our commitment to its value in the production of world-class quality beer beverages. The importance of sustainability is visible in our partnerships with suppliers who share our best practices in water management, our devotion to the communities and watersheds that are affected by our carefully calculated operations, and our acknowledgement of the intricate relationship between business and ecological nourishment.

In assessment of our water management strategy, we formed four key questions to help us along the road to sustainable water management:
• What land use and development strategies can be utilized at our facility to reduce water system resource and energy demands?
• What water efficiency and renewable energy standards, and conservation best management practices need to be identified for cost effective facility/infrastructure upgrades to the existing water system?
• Can our Water Management Plan efforts promote a rate restructuring for our business to encourage water conservation while protecting revenue?
• What outreach and education tools and strategies can be utilized for encouraging water conservation to our patrons and customers?

  • Asheville, NC resides within the Asheville Watershed, consisting of a 22,000 acres ecosystem, located in Buncombe County, NC. The Asheville watershed is a Protected Area, and was designated as a “nationally significant” natural area in the North Carolina National Heritage Protection Plan (1995). A Conservation Easement was established for the watershed in November 1996. This watershed protects one of the largest contiguous spruce-fir forests in the area, which in turn protects the quality of Asheville's water.The Protected Area status is used primarily to provide the City of Asheville and the surrounding areas a clean, safe, and plentiful drinking water source. The Conservation Easement ensuresProtected Property will be retained forever in its predominantly natural, scenic, and forested condition;Protection of native flora, flora communities, and fauna; and Prevents any use of the Protected Property that would significantly impair or interfere with its conservation values. have been efforts to start logging operations in the watershed area as recently as 2005 with area opposition. Selective timbering operations through professional arborists have been proposed to maintain the health of the forest as well as promote economic development. Effects on WatershedForests provide a buffer to filter water and to hold soil in place. They sustain water and soil resources through recycling nutrients. In watersheds where forests are degraded or destroyed through logging, clearing, burning, etc., minimum flows decrease during the dry season, leading to drought, while peak floods and soil erosion increase during the wet season. Logging often destroys natural habitats, resulting in the loss of biodiversity and sometimes leading to the local, and possibly global, extinction of species.
  • The following diagram illustrates the Brewing Process:Malting (wet or dry) – loosens up the endosperm (tissue produced inside of seeds) by degrading the endosperm cell walls; produces enzyme for the the further endosperm cell content degradation during mashing.Milling – provides for optimal conditions for enzymatic activities during mashing for solubilation of fermentable carbohydrates; provides best possible mash separation (i.e. highest possible yield).Mashing – forms an extract with a desired profile of sugars, desired level of protein and minor chemical constituents;conversion of brewing materials in the presence of enzymes, into a fermentable extract suitable for yeast growth and beer production.Lautering – separates extracts won during mashing from spent grain (malt husk) to create wort. It is achieved in either a lautertun, a wide vessel with a false bottom, or a mash filter.Boiling – sterilizes wort, halting enzyme action, concentrates wort, isomerizes hop alpha acid into iso-alpha acid, reduces volatile compound (such as DMS), increases wort color, reduces wort pH, protein coagulate and produces reducing compounds.Cooling – cooling down wort temperature to fermentation temperature in 100oC to 14oC range.Fermenting – converts fermentable sugar to ethanol, carbon dioxide and beer flavorsMaturation – improves/removes unpleasant flavors such as diacetyle (VDK), acetaldehyde, DMS, amylacetate etc.Filtering – makes “bright beer” (gives beer its polished shine and brilliance) and stabilizes.Packaging – putting beer into the containers in which it will leave the brewery. For kegs, this involves flash pasteurization through a plate heat exchanger and then filling the keg to produce the finished product. For bottles, this involves filling and crowning (with a bottle cap), and tunnel pasteurization on a conveyor belt to produce the finished product.PACKAGING - purified air and direct feedingPURCHASING - paper and glass supplies - food products - equipment replacement - supplier requirements Water Usage for Process (3 General Categories) – Brewing Water , Heat Exchanger Water, Cleaning WaterMalting – Water introduced during steeping (soaking grain in liquid (usually water) of a solid so as to extract flavors or to soften it). (Wet process)Mashing – Water introduced with grist from roller mill to mash mixer.Cooling – Water introduced through the plate heat exchanger to take heat away from wort; promotes ideal fermentation.[Notes: Water must be of quality so as not to foul heat exchanger tubes through mineral deposits (precipitates form at/on heat exchanger walls due to decreasing solubility at higher temperatures); Closed loop instead of single pass plate heat exchanger consideration; treatment of wastewater onsite.]Packaging – Water (heated) introduced through the plate heat exchanger to add additional heat (flash pasteurization) to the beer for final packaging to kegs; Bottle/can washing for packaging to bottles/cans.[Note: Purified air and direct feeding considered for bottle/can washing operations. PEPSICO (2012)]Hygiene - COP (cleaning-out-place), CIP (cleaning-in-place) equipment, tanks and pipe lines.[Note: Water used to “pack” lines and tanks thereby excluding oxygen.]Water of required quality for use as the brewing liquor is crucial in creating the beer’s character and flavor. Water impacts beer in 3 ways:(1) Mashing process – enzyme efficiency and wort flavor.(2) Hop utilization – water pH effect on hop utilization.(3) Beer flavor – water adds flavor to beer directlyWater makes up 95% of beer ingredients by weight. Majority of brewers rarely consider water type. Most brewers rarely give it much thought, and water is the least appreciated of beer ingredients. At the other extreme, many brewers spend considerable money on spring water not fully understanding how water affects flavor.High consumption of good quality water is characteristic of beer brewing. An efficient brewery uses between 4 and 5 liters of water to produce one liter of beer. Some breweries use much more water, especially small breweries. Knowing the character/quality of local water source as well as how to adjust it to improve your beer is a critical skill, particularly for more advanced brewers.The effect of brewing water on beer can be characterized by six main water ions: Carbonate, Sodium, Chloride, Sulfate, Calcium and Magnesium.Mineral content [listed as parts per million (ppm) equivalent to one milligram per liter (mg/L)] of local water supply can be obtained from local municipality. Critical ions for each beer type is described below:Lager beer• Soft water with low mineral content, low carbonates• Calcium ions are important at levels > 30 mg/L.Pale ales and bitters• Bicarbonate < 60 mg/L.• Calcium > 125 mg/L• Sulphate > Chloride to bring out the bitter flavorsMild ales and stouts• Carbonates < 60 mg/L• Calcium > 75 mg/L for mild ales• Calcium > 30 mg/L for stoutsBrewing water can be adjusted by the addition of brewing salt(s); Water chemistry can be complicated.
  • -wastewater generated in rinsing, brewing, and cooling process-wastewater has high ratios of solids and isn't pH balanced-treatment tanks remove pollutants by screening, grit removal, and gravity sedimentation
  • -HET/waterless urinals for our employee usage saved over 780,000 gal/yr-cooling system uses 40x less water than a single passage loop-existing boiler maintained and refitted to reuse condensates for 20% cost reduction
  • SOCIAL LICENSE-Provide CSR literature to public -Minimize water impact through measures listed in SMP
