Welcome to Clandestine Brewing Headquarters.

Some time ago, a plot was hatched among a few accomplished homebrewers, could it be possible to turn a passion into a business? After visiting a few nanobreweries for inspiration, we began working on plans for Clandestine Brewing. Now, the secret is out...

Full Beer List

Broken Bitter

Before the 1700's, Malting Barley was a hand-crafted, boutique process that produced inconsistent results. With the introduction of coke-fired kilns, Maltsters improved their control of the process to the point that light-colored or 'Pale' malts were now possible. These new products caught on in a big way, spawning new styles of beer including Porter, Mild, and Pale Ale. In England, the Pale Ale style was divided into several sub-styles including Extra Special Bitter, a classification typically reserved for Pale Ales brewed at over 4.8% ABV.

Although Clandestine's 'Broken Bitters'...

Kölsch I Could

Another German beer that emerged after the availability of lighter colored malts, Kölsch is one of Germany's newest beer styles. Originating in Cologne (Köln in German, both the dialect spoken and a person hailing from that city are called 'Kölsch'), Kölsch is a modern descendant of the Medieval Rhenish Ale brewed throughout the region north of Munich, a distinction it shares with the nearby Dusseldörf Alt (you will hear more about this style in the near future). As demand for light colored beers grew, Cologne's brewers first developed a beer brewed mostly with wheat, quite similar to the...

Milky Way Stout

Although many written accounts suggest that the Milk Stout style originated in the Victorian workingman's lunchtime practice of mixing strong (Stout) Porter with milk, we can be certain that modern versions do not contain any milk at all. The first commercial version of Milk Stout (also called Sweet or Cream Stout) was marketed in 1910 by the Mackeson Brewery of Hythe, Kent, England. Although Mackeson patented the formulation for their new beer, so many patent challenges occurred, they ended up freely licensing their creation. Within a decade there were dozens of new Milk Stouts on the...

Tipsy Hipster

A showcase of our favorite dank, resin-y hops including Apollo, Columbus & Simcoe with a citrus punch provided by Centennial & Amarillo, Clandestine's 'Tipsy Hipster' is not brewed to be the strongest or most bitter IPA, instead we offer the hop-head a completely unbalanced hop-forward beer. Brewed with a base of Maris Otter, Tipsy Hipster has just enough malt to provide a backbone to the waves of hop flavors produced by multiple kettle additions, a hop-stand, and multiple dry-hop additions. These abundant hop additions result in huge citrus and dank pine flavors and aromas that will last to...

Adrian & Christine

Growing up in Colorado, Adrian was surrounded by great craft breweries like Avery, Odell's and Left Hand. After a few misadventures with homebrewing in college and moving to California he took the hobby more seriously. Christine has seen this hobby grow to a garage-consuming obsession and now business. Somehow, she continues to put up with it.

Favorite non-IPA style: Belgian Trippel


Rob considers himself a total beer nerd. He loves experimenting with different styles, ingredients and techniques as part of the brewing process.

Favorite non-IPA style: Saison


A software engineer by day, Colin discovered what would come to be known as craft beer while in college and began homebrewing at about the same time. He returned to homebrewing several years ago, after a hiatus that included training for a number of endurance sports for charity, and enjoys a lot of the DIY aspect of the hobby -- both in making the actual beer, as well as the piecing together equipment. When not working or planning more brewing projects, he can often be found training for his next endurance race.

Favorite non-IPA style: Dortmunder Export


dWiGhT Mulcahy makes a living as a Senior Software Developer in the heart of Silicon Valley during the day but lives a dual life as an avid homebrewer during his free time. He has amassed over 200 ribbons with over a dozen BestOfShows in California and Texas winning multiple awards at National events. The winner of several ProAm events, he has brewed on several "big-boy" systems hoping one day to fulfill his dream of shoveling out grain from the mash tun for a living. Born in Texas but raised in Germany he calls himself a Native German Texan and loves his bier! Prost!

Favorite non-IPA style: Dusseldorf Altbier
