Fierce Whiskers Distillery 2022 Sustainability Report

With the release of its second report, Fierce Whiskers continues to raise the bar in the spirits industry by adding Scope 3 emissions.

Fierce Whiskers (FW) is a unique American bourbon distillery that embraces the ethos of “greatness through stubbornness.” Making world-class whiskey is not easy, and doing so sustainably adds another layer of complexity. FW is focused on producing the highest quality whiskey, from grain selection to barrel aging and bottling, with an emphasis on efficiency throughout every step of its process. FW sources local grains whenever possible, utilizes low-impact Kelvin Cooperage white oak barrels for aging its whiskey, and has built a unique five-story rickhouse with louvers to leverage the harsh Central Texas climate in the aging process. 

FW aims to be a foundational building block in the craft spirits world of Austin, Texas, while staying true to its roots in the local community. FW welcomes visitors to its tasting room and its six-acre distillery property daily and routinely hosts indoor and outdoor events featuring local musicians and a variety of food options from local chefs.  

What’s New in the 2022 Report

Since breaking ground in 2018 and releasing its first sustainability report in September 2021, FW has continued to make progress on its journey to bring fantastic whiskey to Austin, Texas, while also furthering its commitment to environmental sustainability. This report has been updated for 2022 to reflect progress made since its initial sustainability report.

Since its initial report release, FW has been busy ramping up to full-scale operations. This growth increased its overall emissions, but they have successfully delivered an emissions intensity reduction from 2021 to 2022 by leveraging the sustainability strategies and energy efficiency built into every step of its operations. Download the full report for the data and calculations. Other highlights since the initial report include:

• The addition of Scope 3 emissions, inclusive of ingredient production and transport.
• The launch of the world’s first carbon-negative bourbon, Five O’Clock Shadow.
• The launch of carbon-neutral Smoke + Mash Volume One.
• Sharing FW’s sustainability journey online and at South by Southwest (SXSW).
• Ramping up spent grain donations to local farmers to 125,000 pounds per month.

As FW prepares to roll out its Texas Straight Rye Whiskey onto store shelves in the U.S., it continues to consider superior taste and sustainability in every decision. Looking ahead, FW will remain focused on balancing the trade-offs between water and carbon in ingredient sourcing, optimizing energy and water usage at its distillery through monitoring and automation, and providing a delightful experience at its six-acre property where the Austin, Texas community gathers to enjoy music, food, and the best tasting whiskey in Texas.

“We didn’t have to retrofit sustainability into our brand or our processes—we thought about it from day one, and it’s been pretty impactful in terms of our approach and how things happen.

Co-Founder Tri Vo, on incorporating sustainability into operations

Grain to Glass

FW is focused on ensuring the highest quality of whiskey is produced, beginning with grain selection, barrel aging, and bottling. FW begins with milling regionally produced grains to create unique mash combinations for its whiskeys, including bourbon and rye. FW worked closely with a thirty-year Kentucky bourbon veteran to carefully select each piece of equipment, including a Kentucky-produced copper still and a custom rickhouse.

Throughout the distillation and aging process, FW has introduced its own techniques to leverage the extreme atmospheric conditions in Austin, TX, to produce a distinctly Texan whiskey. This includes improved efficiency of equipment using sophisticated automation systems that optimize quality control, consistency, and safety.

By weight, over 97% of the grains utilized by FW are produced near Amarillo, Texas. After production, FW demonstrates its commitment to participating in the circular economy by donating spent grains to local farmers to minimize waste and ensure reuse. Farmers utilize the spent grains as animal feed.

As with traditional American Bourbon, FW ages bourbon and rye in new white oak barrels for years at a time, giving its whiskeys distinctive and rich flavors. FW selected Kelvin Cooperage white oak barrels as Kelvin Cooperage ensures 100% of every white oak log purchased gets processed and utilized, with oak scraps being utilized in the toasting process as this can yield different oak profiles, and has created a used barrel program for reselling once-filled barrels and minimizing waste. Kelvin Cooperage is a member of the White Oak Initiative which has contributed to white oak being the second fastest-growing hardwood resource, including an annual growth rate exceeding harvest by 70%.

Fierce Whiskers Launches World’s First Carbon-Negative Bourbon

The Austin distillery is releasing 257 carbon-negative bottles from Barrel #47 in a limited release.

Harnessing the Texas Climate

The five-story bonded rickhouse, with four stories above ground and one below, is uniquely designed to allow FW more creative control over the flavor of its whiskey while harnessing the harsh summer climate conditions in Central Texas. FW selected the building location during the design phase based on the outcomes of a wind study, allowing the rickhouse to capture ideal prevailing winds. The louver system, with manual louvers on each side of the building, harnesses airflow to aid in temperature regulation. Typically, rickhouses have small windows rather than manual louvers. FW installed its own weather system to monitor temperature and humidity, allowing the distiller to make louver adjustments based on real-time weather data.

A natural ventilation analysis was conducted to optimize direct airflow and fast ventilation based on the main wind direction. 

Energy Impacts

FW selected high-efficiency equipment, including a boiler with an industry-leading efficiency rating. They have also deployed automation systems to ensure efficiency and quality control over time. Facilities of this size do not typically have automation systems to this extent. As an example of FW’s commitment to reducing energy waste, doors are equipped with sensors to cut off the HVAC system when opened. Efficiency was considered throughout the distilling process, building operations, interior and exterior lighting, and the rickhouse. To further reduce the impacts of its energy consumption, FW installed a state-of-the-art solar project consisting of a rooftop solar array with a highly efficient inverter.

Utilizing utility data from the start of operations through 2022, FW has quantified its energy and emissions intensity. Full data and calculations are included in the downloadable report, with a summary shared below.

A Continued Focus on Water & Carbon Tradeoffs

Austin’s climate is part of what makes FW’s aging process unique, but the summer climate also creates significant landscaping water demand. FW is evaluating rainwater collection as a potential option moving forward to reduce water consumption.

While not directly related to its water consumption, FW is actively looking into the impacts of water and carbon on grain selection in relation to where their grains are produced. Amarillo’s primary water source is the Ogallala Aquifer, which is used at a rate that exceeds recharge; Texas as a whole remains in severe water shortages as demand far exceeds supply. Selecting ingredients produced outside of Texas would increase carbon emissions associated with transport.

As in many sustainability choices, there is not a clear winner—selecting regionally produced grain from a water-stressed region adds to the complexity of FW’s decisions and is an important consideration moving forward.

The Future of the Brand

FW focuses on utilizing the best ingredients combined with a data-driven approach to ensure the highest quality and most enjoyable taste from each barrel. This means transparency in production and its sustainability efforts. Every single decision revolves around uncompromising quality while keeping energy efficiency in mind. As FW ramps up production, it plans to grow its impact locally: FW is proud to serve Austinites, source grain as close as possible, and support local farmers with its spent grain. FW strives for continual improvement in all that it does and will continue to share data every step of the way.
