Humble Beginnings

At Mammoth Oak Brewing Company, we know about humble beginnings. What starts as a mere acorn can grow to be a mighty oak. A little yeast can produce beer that draws the masses. A shared dream can become a household name. Though our branches may grow skyward, our commitment is to Stay Rooted in Florida and to brew a wide-range of beer with uncompromising standards.

"We're proud to be able to give back and be active in the community; to make Leesburg a better place; to feel like we're making a difference."

Isaac Johnson, Head Brewer & Co-Founder

"[My favorite thing about the craft beer industry is] sharing. I really like that it brings a community together over our mutual enjoyment, and we aren't afraid to share our passion with everyone else. We are happy to talk about, and happy to share, any beer we drink."
