The intersection of general aviation and craft brewing represents one of the most logistically complex niche sectors in the American beverage industry. At the center of this movement is FlyteCo Tower, a Denver-based brewery and entertainment complex housed in the historic air traffic control tower of the former Stapleton International Airport. For six consecutive years, the brewery’s flagship seasonal project, the "Hop Is My Co-Pilot" Fresh Hop IPA, has relied on a high-stakes aerial mission: flying a small aircraft over the Continental Divide to harvest fresh hops and returning them to the brewhouse within a six-hour window. However, the 2025 harvest season has marked a significant departure from tradition, as unpredictable weather patterns and narrow harvest windows forced the grounding of the annual flight, highlighting the inherent risks of "just-in-time" agricultural logistics.
The Logistics of the High-Altitude Hop Run
The annual hop flight is a mission defined by razor-thin margins. Each August or September, FlyteCo co-founder and president Eric Serani—a certified flight instructor and aerospace engineer—pilots a Van’s Aircraft RV-10, a four-seat, single-engine kit plane, from Erie Municipal Airport to the Western Slope of Colorado. The destination is typically Billy Goat Hop Farm in Montrose, a journey that requires navigating the treacherous terrain of the Rocky Mountains at altitudes between 11,000 and 13,000 feet.
The flight covers approximately 175 nautical miles each way. In a standard year, the timing is choreographed with military precision. While Serani is in the air, the brewing team at FlyteCo Tower begins the "mash-in" process. By the time the aircraft touches back down at Erie Municipal, laden with roughly 20 to 100 pounds of fresh Chinook, Cascade, or Nugget hops, the wort is ready for the addition of the "wet" cones.
Fresh hop brewing differs fundamentally from standard brewing, which utilizes dried and pelletized hops. Fresh hops contain upwards of 80% moisture and begin to degrade almost immediately after being picked. To capture the delicate, volatile oils and grassy, floral aromatics unique to the fresh harvest, brewers must utilize the hops within 24 hours—and ideally within four to six hours—of harvest. For FlyteCo, the use of private aviation is not merely a branding exercise but a functional solution to Colorado’s geography, turning a six-hour mountain drive into a 90-minute flight.
A Legacy Rooted in Colorado Aviation History
The foundations of FlyteCo are deeply intertwined with the history of flight in the Mile High City. Eric Serani’s personal history in aviation began at age three, influenced by his grandfather, who operated a 1946 kit plane. Serani’s trajectory—from soloing an aircraft at age 16 to earning his pilot’s license at 17—was supported by the Experimental Aircraft Association (EAA) Chapter at Erie Municipal Airport. This community support later informed FlyteCo’s corporate social responsibility mandate, which includes donating 10% of all profits to aviation-themed scholarships and initiatives, such as the Young Eagles program.
The brewery’s physical location is a testament to Denver’s status as a global aviation hub. Stapleton International Airport, which opened in 1929, served as the city’s primary airfield for 66 years. By 1961, it was the third busiest airport in the world. Although it closed in 1995 to make way for Denver International Airport (DIA)—currently the third busiest airport in the United States—the iconic 11-story control tower remained.
In 2022, FlyteCo Tower opened in this refurbished landmark, transforming the decommissioned aviation infrastructure into a multi-level hospitality venue. The facility includes an on-site aviation museum curated by historian Sean Henson, featuring exhibits on Louis Paulhan, the first aviator to fly in Denver in 1910, and Emily Howell Warner, the first woman hired as a pilot by a scheduled U.S. airline.
The 2025 Grounding: Analysis of Weather and Harvest Constraints
The cancellation of the 2025 hop flight underscores the vulnerability of the craft beer supply chain when coupled with general aviation. For the first time since the brewery’s inception in 2019, persistent cloud cover and volatile atmospheric conditions over the Rocky Mountains prevented a safe flight window during the peak harvest at Billy Goat Hop Farm.
Aviation experts note that mountain flying in small aircraft like the RV-10 requires high visibility and manageable wind speeds, particularly when crossing the Continental Divide. Density altitude—the pressure altitude corrected for non-standard temperature—can also significantly impact aircraft performance in high-altitude regions like Montrose and Denver. When weather delays pushed the flight schedule back by several days, the harvest window at the farm closed, as the hops reached a stage of maturity where they had to be picked and dried immediately to prevent spoilage.
"The harvest is always last minute," Serani noted regarding the 2025 season. "They don’t know when the hops will be ready until a few weeks prior, and we don’t know the weather until the day of. Every time we’ve successfully made this beer in the past, it felt like a miracle."
The failure to complete the flight has broader implications for the "Hop Is My Co-Pilot" release. Without the immediate delivery provided by the aircraft, the brewery is forced to either pivot to overnight commercial shipping—which lacks the celebratory community aspect of the flight—or forego the fresh-hop designation for the year. For 2025, the team has opted to wait until 2026 to resume the aerial tradition, prioritizing safety and the integrity of the "farm-to-plane-to-kettle" narrative.
Strategic Shifts in Production and Hospitality
The challenges of the 2025 season coincide with a broader strategic evolution for the FlyteCo brand. Earlier this year, the company closed its original Tennyson Street location to consolidate operations at the Tower. To maintain its supply of flagship beers while focusing on experimental, small-batch releases at the Tower’s 2.5-barrel system, FlyteCo entered into a contract brewing partnership with Denver’s Copper Kettle Brewing Company.
This shift allows the FlyteCo team to lean into the "experiential brewery" model. The Tower facility has been expanded to include bowling alleys, arcade games, and mini-golf, positioning the brand as a destination for "eatertainment." This diversification is a common trend in the maturing craft beer market, where taproom sales are increasingly driven by unique environments and activities rather than product alone.
Economic and Community Impact
FlyteCo’s commitment to the aviation community remains a core component of its business model. By donating 10% of profits to flight training and youth aviation programs, the brewery addresses a critical need in the aerospace industry: the pilot shortage. According to data from Boeing’s Pilot and Technician Outlook, the industry will require 649,000 new commercial pilots over the next 20 years. By sparking interest in aviation through its themed environment and direct financial support, FlyteCo serves as a grassroots recruitment tool for the sector.
The "Hop Is My Co-Pilot" project, while economically inefficient—with fuel costs often exceeding the market value of the hops—serves as a high-visibility marketing event that strengthens the bond between the brewing and flying communities. In previous years, the flight has involved up to eight separate aircraft, creating a "fly-in" event that draws regional attention to Colorado’s hop farms.
Conclusion: Looking Toward the 2026 Horizon
The grounding of the 2025 hop flight serves as a reminder of the unpredictability of agricultural and aviation endeavors. While the absence of the Fresh Hop IPA is a disappointment for local enthusiasts, the brewery’s resilience and focus on its broader mission suggest a stable flight path forward.
As the industry looks toward the 2026 season, the FlyteCo team remains committed to the aerial harvest. The integration of high-level engineering, historical preservation, and traditional brewing techniques ensures that FlyteCo Tower remains a unique entity in the American craft landscape. For now, the brewery continues to serve its community through its aviation museum and diverse tap list, maintaining the spirit of flight even when the planes are temporarily grounded. The pursuit of the "perfect" fresh hop beer remains an elusive goal, much like the early days of aviation itself—a challenge defined by the constant negotiation between human ambition and the forces of nature.
