PEARL RIVER, NY – After 18 years of brewing beer, building community and helping create lasting memories in Pearl River, Defiant Brewing Company is preparing to pour its final pints during its closing weekend, set for the end of this month.
For founder and brewmaster Neill Acer, the end of Defiant marks the close of a long chapter that began with a simple ambition: to stop building other people’s breweries and finally create one of his own.
“I’d won some international medals and had been brokering and installing breweries, getting other people’s dreams running, so to speak,” Acer recalled. “I ended up with some extra pieces of equipment and thought that all the flying around, setting things up was getting tiring. And I thought, ‘It might be a nice time to start a family. Wouldn’t it be great if I could still make beer for the rest of my functioning life?’”
That opportunity came in 2005, when Acer launched Defiant in Pearl River as a one-stop brewery and bar. Over the years, the business grew from a one-man operation into a well-known local institution, with Acer building a reputation for inventive craft beer and a fiercely hands-on approach to brewing.
A Career with a History of Quality
Born in the Bronx in 1971 to Gerard and Eleanor Acer, Acer was raised in New York and later graduated from the University of Rochester in 1994, where he double-majored in English and psychology. It was there, while home brewing as a hobby, that he began what would become his career’s defining pursuit. He later received formal brewing training at the Siebel Institute of Technology and the World Brewing Academy in Chicago.
Before opening Defiant, Acer brewed professionally throughout the Hudson Valley and beyond, working in places including The West End in New York City, The Colorado Brewery and Steakhouse in Danbury, Connecticut, and Mountain Valley Brew Pub in Suffern. By the time he opened his own brewery, he brought with him more than 20 years of experience, international judging credentials, and award-winning beers, including two International gold medals in the World Beer Cup.
At Defiant, Acer built a beer menu that he said was never meant to stay still. The brewery became known for offering roughly 30 different styles of ales and lagers year-round, with 10 to 15 available at any given time, depending on customer response, ingredient availability and, as Acer put it, his own mood.
All of the beer was brewed in-house, fresh and without preservatives or GMOs. Ingredients were sourced globally, with Acer choosing barley based on the flavor profile needed for each recipe. Once delivered, the grain was milled on site and brewed with additions such as hops, orange peel, herbs and spices.
“All ingredients can be traced from grain to glass,” Acer said.
To explain brewing to newcomers, Acer often used a comparison that stripped away the mystique.
“In the way that coffee is sort of liquid coffee bean juice, beer is pretty much liquid barley juice,” he said. “It’s this ancient and beautiful way of preserving nature’s sunshine.”
Even for customers who believed beer was not for them, Acer saw Defiant as a place for discovery.
“People will say things like, ‘I don’t like beer,’” he said. “I’ll say, ‘Well, have you had an ale?’ … When you get one that’s fresh and all natural, four feet away from the tank it was made in, it’s a magical thing. You owe it to yourself and your life to try it.”
Over nearly two decades, Defiant became more than a brewery. It became a gathering place, a local landmark and, for some, the setting of life-changing moments.
Many Memories at Defiant
Acer recalled one early encounter between two customers who arrived separately and appeared to be on a first date. He served her a Little Thumper and him a Triple Skull Crusher, one of his favorites. Before long, the two were sharing a bottle and returning week after week.
“Fast forward, they’re there every Friday,” Acer said. “Fast forward a little bit further. They want to get married in Defiant.”
The couple eventually did just that, with Acer becoming part of the ceremony after obtaining an officiant’s license.
“And they’re happily married,” he said. “Ten years later.”
Those kinds of stories helped define Defiant’s place in Pearl River. Acer, a member of AOH Division III in Pearl River since 2006, also has ties to the Pearl River Rotary and the Pearl River Chamber of Commerce. In 2018, he was named Hibernian Business Person of the Year, a recognition that reflected both his business success and his standing in the community.
His family roots also remained central to his story. Acer and his wife, Amy, have two children, and in 2011 he brought his family to Ireland to visit relatives, old homesteads and the family bog, connecting a new generation to the places his maternal grandparents left behind when they came to the United States from Roscommon and Leitrim in the 1920s.
Now, as Defiant approaches its final weekend, Acer leaves behind more than an 18-year business run. He leaves a brewery that introduced countless customers to craft beer, employed more than 20 people at its height, earned international recognition and gave Pearl River a place where beer, conversation and community could mix.
For many patrons, Defiant’s closing will mean saying goodbye to a favorite local spot. For Acer, it marks the end of the dream he turned into reality — one pint at a time.
