A glimpse into the questions Michael posed to OisínSweeney.

1. What is Jervis Bay Brewing Co.?
   
   Jervis Bay Brewing Co. is a community-focused craft brewery based in the scenic coastal region of Jervis Bay, Australia. The idea was born from a love for great beer and a desire to create a welcoming space that brings people together. Oisín and his co-founders wanted the brewery to be more than just a place to drink—they envisioned it as a hub for locals and tourists, offering not only high-quality craft beer but also connection, inclusivity, and sustainability.
   
   

2. How did you go about starting the brewery?
   
   Oisín Sweeney shared that he started Jervis Bay Brewing Co. with three like-minded co-founders, driven by a passion for craft beer and a desire to create a welcoming community space. After years of conversations and dreaming, they committed to the idea in 2017 and spent two years planning, researching, and building the business. They carefully selected the location, built strong local relationships, and navigated the complex process of securing licenses and approvals. Their approach was grounded in collaboration, patience, and a clear vision—to build a sustainable brewery that brought people together and reflected the spirit of Jervis Bay.
   
   

3. What kind of roles do you and your co-founders play in the business?
   
   Oisín Sweeney shared that he focuses on community engagement, partnerships, and storytelling for the brand. One co-founder (Oisín) manages the brewing operations and production, while the other (Paul) oversees finance and business administration. Together, they play to their strengths and collaborate on key decisions.
   
   

4. What’s your approach to branding and standing out in the market?

From beer names to visuals, everything reflects the spirit of Jervis Bay and creates a genuine emotional connection with customers.
   
   

5. Have there been any surprising lessons or mistakes along the way?
   
   According to Oisín Sweeney One surprising lesson was underestimating the initial funding required, leading to the "brew puppies" investment. A mistake was the initial brewery configuration which hindered double brewing. With hindsight, Oisín would have delayed the expansion due to changing economic conditions. He also found the sheer amount of hard work involved initially surprising.
