Sustainable Spirits

Far North Spirits' sustainability measures described in detail.

Estate Grown Means A Smaller Carbon Footprint

Our shipping-associated carbon footprint is significantly less than most distilleries, due to one simple fact: the bulk of our raw materials are grown outside our door.

Consider this: A pallet or 80 cases of bottled whiskey weighs 1,600 pounds, which sounds like a lot. But the grain needed to produce that whiskey weighs a whopping 10,000 pounds. If the grains needed to make that whiskey must be shipped to the distillery, that transport significantly increases the distillery's overall carbon footprint.

Compare this with a pallet of whiskey produced at an estate distillery. There is shipping associated with moving the bottled spirit to its final retail destination, but nearly none associated with the raw materials.

In other words, it takes about one-sixth the transportation energy to move the whiskey from a Midwest farm distillery to a retailer on the coast, as it does to ship grain from the midwest to a coastal distillery. 

 

Production & Distilling

All grains except malt barley are grown by the distiller within a mile of the distillery, and stored in bins on site. This eliminates the need for both the shipping and bagging of grain.

After distillation, spent grains are spread on nearby fields. Because most of the starch has been consumed during fermentation, the high protein levels of spent grains make them an excellent fertilizer. Because cellulose is also left behind after fermentation and distillation, this adds organic matter back to the soil, improving its health.

Very little landfill waste is produced by the distillery. The majority of materials used in the production process are either source-reduced, compostable, or recyclable – so much so that it is not even necessary to maintain a trash dumpster on site.

Stills and mash cooker are steam heated. Steam is produced by a propane-fired steam boiler, the burner of which is over 95% efficient. Propane is a cleaner-burning and more efficient (BTU for BTU) fuel than even natural gas, from which it is derived. Steam condensate is collected and returned to the steam system continuously, significantly reducing makeup water consumption.

Water used for mashing is collected from the cooling water system on the previous mash. The “hot” cooling water is siphoned off from the system into a steam heated tank that prepares it for the next mash, thereby reducing the number of btu’s necessary to bring it to mashing temp (raising the temperature of water from 140F to 200F takes less heat than bringing it from 50F to 200F).

Cooling water is recirculated in a closed loop system, and the distillery is located far enough north that evaporative cooling is all that is necessary. This eliminates the need for a more energy-intensive chilling system. This is another reason why production is increased during the winter months – cooling capacity for the cooling water is in extreme abundance just outside the building.

Sourcing

Mindful sourcing and careful choosing of vendors nearly eliminates disposal concerns in the way of packaging.

Botanicals and spices are sourced through a careful channel examination, with a particular focus on the sustainable production of the vendor.

Barrels are purchased from cooperages in Minnesota, which decreases transportation distances. Cooperages are also chosen for their responsible forestry practices.

The distillery is on a rural septic system, and this requires the use of sustainable cleaning chemistry so that it does not negatively impact the system.

 

Farming

Because crop yields do not need to be maximized for commodity sale, there are many advantages for sustainable agricultural practices:

Heirloom and organic hybrid corn requires significantly less chemical input than GMO corn.

Because rye is our principle raw material, enough corn can be grown in a single season for the next two years of distilling. This enables us to plant the corn field with a green manure cover crop and allow the soil to rest and digest the corn stalks. This eliminates the need for a constant rotation of GMO corn and soybeans and their subsequent inputs, as is currently the practice nearly nationwide.

Rye is a hardy crop that is also an allelopath – it chokes out the vast majority of weeds. The use of herbicides is nearly eliminated altogether. Because we are growing rye for distilling and not milling, we are striving for the lowest protein levels possible (starch = alcohol). This means that fertilizer must be kept to a bare minimum, and ultimately it may even be possible to fulfill our fertilization needs through spent grains alone.

Rye is planted into canola stubble, using a no-till process. This has two distinct benefits. First, the stubble encourages the collection of snow during the winter, providing an insulating blanket for the rye. Second, it provides organic material which improves soil health for the following growing season.

Building & Grounds

All steel construction, which significantly reduced construction waste on-site.

Heated with in-floor, closed-loop glycol radiant system. This is one of the most efficient heating systems for a building of this size, requiring only a small, propane-fired boiler. Heating efficiency is increased by larger production runs in the winter months, when heat produced by the stills and mash cooker is not considered waste heat.

All distillery floor lighting is T5, which reduced the number of lamps and luminaries needed upon initial installation, and has decreased energy consumption.

Over 600 trees were planted around Far North Spirits in 2015, with additional plantings of native prairie grass scheduled in 2016 to act as buffer strips, erosion control, wildlife habitat, and wind breaks. Wildflowers are an important part of these native prairie zones, as they attract bees and other beneficial pollinators, as well as fly and mosquito predators.

Cooling in summer is accomplished through strategically placed windows that open. The distillery is located in a level 3 wind zone, which provides ample air circulation on most days without the need for fans.

Rain runoff from the building’s roof is channeled into ditches planted with native prairie wetland mixes. This practice both slows the flow of water, thereby decreasing erosion, and improves water quality by removing sediment and other potential contaminants. These ditches are also beginning to serve as nesting cover for wildlife.
