Small Brewery.

Big Taste.

Local Ingredients + Science + Passion = Great Beer


Lethbridge’s Littlest Brewery that Could!


We are the best-kept secret in Lethbridge! Located in the heart of the historic warehouse district known as the Upper East Side, we are a hidden gem of family-run, local-beer goodness. Come into the brewery and take advantage of our Tasting Room, browse the local crafts, enjoy a pint and some local snacks from our friends and local producers.

All of the beer is made right here in our 1,000 square meter warehouse by our owners Kris Fischer & Kelti Baird. It is hand made, hand-bottled, and hand capped/labelled. The process takes between 14 and 21 days start to finish, and all beers are bottle conditioned for extended shelf-life and quality.

The Tasting Room features tables and chairs for 20, some couches and armchairs, a 1967 record player/radio cabinet, and board games. Come in and browse our small (but excellent) vinyl collection, grab your fave board game and order up some pints for a fun, inexpensive night out.

After a phenomenal season on the Patio, we are moving indoors and will feature live shows in the Tasting Room throughout the winter season! The Tasting Room is also available for private rentals. Contact us at theorybrew@gmail.com to book your event with us!

As always, we are only as good as the people who support us. Our customers have become our close friends, and we thank you from the bottom of our hearts for every dime you give to helping our dream become a reality! In turn, we are pleased and proud to support our local makers, crafters, and producers! Thanks to everyone who comes in for a visit, and to everyone province wide purchasing our product. Cheers to you!

Our Brews

Thanks for your interest in [Theoretically] Brewing Co. Our brews are unique creations that change slightly depending on the season, year, and what ingredients are available at any given time. Small batch experimentation is frequent at this brewery. Below are some of the brews you can expect to find with us!


Base Elements are available year round in 2 sizes: 341mL bottles and 650mL Bombers!

Base Elements

Usually every brewery has between 3 and 5 beers they make on a regular basis. These are known as the 'core lineup' but we call them 'Base Elements'. They are: Study Buddy Hefeweizen, Curiosity Amber Ale, Frequency Hopper English IPA, Ionic Irish Red Ale, and BHB Stout. You can find these available in 341mL standards and 650mL bomber bottles at the brewery, and around Alberta.

Because we pull our water directly from the City of Lethbridge, which gets its water from the Oldman River, we can expect seasonal fluctuations in the water chemistry of our brews, which can have a direct impact on flavour profiles. We think this is okay. We appreciate that craft beers are less about consistency and more about creating a great-taste experience each and every time. You may notice the flavor profiles of our brews change from time to time, but will always be enjoyable!

We are proud of our local ingredients. Our beers are brewed with 100% Canadian ingredients!

Seasonal Releases

Due to the seasonal variations in taste or style preferences and the availability of ingredients, some beers will only be released at certain times each year. We like to make our beer with fresh, locally-sourced ingredients that we can either use whole, puree, or extract on site. This means that some beers with fruits or botanical additions may not be available some months of the year. Keep an eye on social media for the next up-coming seasonal releases, or contact the brewery if you are curious!

Seasonal releases include: Annual Women's Brew (various styles) released March 8, Quantum Wheat Ale March - June, Fomenko's Chronology Raspberry Sour June - July, CFC Buster Habanero IPA August - September, Autumn Seasonal (various styles) September - November, Space Chai-m Continuum Chai Vanilla Porter - December 1st - sell out (around the 10th). Publish or Perish Porter November - February.

Curiosity Ale changes recipe periodically so it is always a little different!

Being the smallest brewery south of Calgary, we can enjoy some flexibility in what we brew, without committing too much capital to weird and experimental ideas. Occasionally our Brew-Master Kris will get a wild look in his eye, and tell Kel 'I've got an Idea' and what comes out is a generally interesting and altogether excellent brew. Some of these brews have moved on to become seasonal releases, and some have even become core beers, but most get relegated to fondly-remembered history.

Curiosity Ale is the one beer that sticks around because it is always a Curiosity. This ale, which began life as our Amber Ale and one of our first brews, has morphed into an ever-changing, recipe-shifting charismatic member of the [Theoretically] Brewing Co portfolio. It is always brewed with slight differences, and will occasionally be produced as something completely different.
