With Jean Caragher
For CPA Trendlines
In the world of accounting, niche specialization is often a deliberate strategy. For Tim Allen, CPA, however, his journey into winery finance was more serendipitous than strategic. With over 30 years of experience—including time at a Big 4 firm, leadership roles at multiple wineries, and now managing a successful boutique firm exclusively dedicated to the wine industry—Allen has carved out a unique space for himself and his team.
“I didn’t set out to specialize in wineries—it just happened,” Allen says. “But looking back, every step led me here.”

Allen’s accounting came unexpectedly during his tenure at Deloitte’s San Francisco office. While his colleagues gravitated toward high-profile clients, Tim found himself drawn to wineries—clients that others overlooked. The opportunity allowed him to work closer to his family in Santa Rosa while developing a deep understanding of the industry’s financial intricacies.
After spending 17 years in operational finance roles at wineries, Allen realized that his career had been dictated by winery sales—each time a winery was acquired, he found himself looking for a new opportunity. When the financial crisis of 2009 limited job prospects, he took the plunge and founded the Allen Wine Group. Starting with just himself, the firm focused on providing outsourced accounting services for wineries. Over the years, the firm has expanded to a 26-person team and now serves 50 winery clients. Most recently, the firm launched a tax practice to complement its client advisory services (CAS).
One of the firm’s greatest assets is its firsthand industry experience. Many of the CPAs at Allen Wine Group have worked in wineries themselves, allowing them to provide insights beyond basic financial statements. Their deep understanding of cost accounting, cash flow management, and banking relationships makes them trusted advisors in an industry where financial expertise is often lacking in-house.
“If I didn’t have hands-on experience in wineries, I wouldn’t be nearly as effective at advising them,” he admits. “It’s one thing to read about an industry, it’s another to live it.”
Focusing exclusively on wineries has allowed Allen Wine Group to build deep expertise and strong relationships, but it also comes with limitations. Unlike traditional firms that serve a broad range of clients, the firm is selective about its clientele. With 59 winery clients and only one spirits client, their dedication to the niche is clear. However, Allen believes this focus strengthens their value proposition. “Focusing on a niche means saying no to a lot of things—but it also means becoming the go-to expert in something that truly matters to your clients,” he says.
Marketing for a specialized CPA firm looks different from traditional accounting firms. Allen Wine Group relies heavily on relationships within the industry. Bankers and attorneys frequently refer clients, while networking events and educational seminars further cement their authority. “This industry is built on relationships,” Allen advises. “When you show up consistently, share knowledge, and genuinely help, the business takes care of itself.” The firm also hosts a quarterly Wine Financial Group event for industry professionals and offers a NASBA-accredited CPE Winery Education Series, which Allen himself teaches.
Hiring for a niche firm requires a different approach. Traditional CPA firms prioritize audit and tax expertise, but the Allen Wine Group seeks professionals with controller-level winery experience. While the firm values CPAs, Allen recognizes that hands-on operational knowledge can sometimes be even more valuable than a credential when serving winery clients. “We don’t just look for CPAs—we look for people who know wineries inside and out,” he says. “That makes all the difference.”
For CPAs considering specialization, Allen offers this advice: Get industry experience first. Understanding the unique challenges of a sector from the inside out allows for stronger advisory services. He also stresses the importance of leadership, networking, and persistence—niche firms don’t develop overnight.
Allen acknowledges that launching a niche within a traditional CPA firm can be challenging. “If you assign an audit or tax professional to lead a niche practice, they’re likely to get pulled back into their old work,” he explains. Fully committing to a specialization requires strategic firm-wide buy-in.
Allen’s perspective on the wine industry extends beyond the numbers. He understands the real-world operational challenges wineries face, from compliance in 49 states to IT migrations and financial reporting. His passion for the business even extends to wine itself—his favorite being a white Burgundy from Chablis.
Allen’s success story is a testament to the power of specialization. What began as an unintentional career path has grown into a thriving firm that not only serves wineries but is shaping the future of winery finance. For CPAs considering a niche, his journey proves that deep industry knowledge, strong relationships, and a commitment to specialization can lead to incredible success.
