About Us

A locally owned and operated brewpub, Big Trout Brewing offers a wide selection of craft beers, tasty bites and a comfortable environment. We are located at Cooper Creek Square in downtown Winter Park next to the Winter Park Transit Center on the bottom level of the parking garage overlooking the courtyard. Enjoy some drinks inside our spacious open brewery or sit outside on our patio and take in the fresh air and warm sunshine.

How Did We Get Here?

Owners, Tom and Emily Caldwell, have been proud members of this amazing community since 2006 and are eager to give something back by way of delicious libations. We started working on a plan to start our own brewery in the spring of 2017, with the passion for brewing delicious beer, the desire to give something back to Grand County and provide for our growing family. As we dove into the business plan and started tossing around names, Tom was walking into daycare with our daughter, who was 2 years old at the time, and asked “What do you think about Trout Brewery?” To this, our budding angler responded, without hesitation, “No daddy, BIG Trout Brewery.” And so, it was. We officially opened the brewery on June 12, 2020.

Who Makes the Beer?

Co-owner, Tom Caldwell, has been professionally brewing since 2009, when he started at the Grand Lake Brewery. He was hired to bottle beer and his skills were quickly identified and he was brewing with the brew master in no time. It is clear, to all those who have ever had Tom’s beer, that he not only has the passion for brewing beer, but also possesses an intuition for crafting what we all want to drink. In addition to beers, Tom is excited to eventually offer some craft sodas.

What’s the Big Deal?


We have invested in a state-of-the-art brewhouse through IDD, a brewery equipment company out of California, called a High Efficiency Brewing System (HEBS). The HEBS utilizes a Mash Filter which offers several environmental and operational efficiencies of which we are proud.

First, the Mash Filter reduces water waste by 20-30%. Sitting at the headwaters to the Colorado River, one of the most endangered rivers in North America, we believe reducing our water usage and waste is extremely important.

Second, the mash filter increases our extraction rate to roughly 98%, compared to a standard system extraction rate of 75-80%. This means we can get the most out of our grain and can use 10% less per batch.

We are excited to be able to do our part for the environment, the rivers we love to fish and this wonderful community. We are proud of our product and proud of the companies we support, like American Keg, the only American keg company producing kegs right here in the USA with American steel, IDD, which produced our brewhouse out of California, and Forgeworks, which produced our tanks in Colorado.
