Cold Brew Coffee


Feel the cold-brew buzz.

Cold brew is changing the coffee world.  Third wave and second wave producers both are brewing, bottling and kegging as much cold brew as they can because of its low-acid and complex flavor profiles. Roasters are becoming brewers and baristas are becoming bottlers.

Whether you are a coffee roaster who needs to add brewing equipment to your roastery or a craft brewer who wants to adapt your equipment to handle coffee, we can help.  We offer a complete range of equipment from 1 barrel systems all the way up to 10 barrel systems that can brew over 300 gallons in a batch.



There are two ways to make cold brew coffee. The traditional way is to immerse the beans in cold water and let time work its magic passively. The new way is active extraction; moving water through the beans to actively to extract the flavor compounds from the beans. On the larger scales of commercial production, it just makes sense to move to active extraction to save time, labor and space and to improve the consistency and flavor of your product. The BrewBomb is a very exciting new technology in cold brew active extraction cold brew, and Stout Tanks is the exclusive supplier of the BrewBomb in the Americas.


Benefits of Active Extraction:

  • Faster. Brew a complete batch of cold brew (up to 100 gallons) in as little as 2 hours.
  • Higher volume. Brew double or triple batches in every shift for hundreds of gallons in 8 hours. If you work multiple shifts, you can double or triple your capacity in a single day.
  • Tastes better. Design the cold brew extraction specifically for the flavor profile of your beans. For every roast, you can adjust the grind size, the flow rate, and the extraction time to find your perfect cold brew flavor.
  • More consistent flavor. Once you define your preferred flavor profile, you can replicate the batch every time. Create a consistent product time after time.
  • Eliminate filtration. The coffee acts as its own filter bed, trapping all of the particulates in the grounds, keeping it out of the brew. Eliminate the expensive and time consuming step of filtering your cold brew before kegging
  • Less Labor. The BrewBomb is designed to make spent grounds handling a breeze. Drop the spent grounds into the compost bin as easily as dropping a napkin in the trash.
  • Less Space. The BrewBomb takes up less than 20 sq. feet of space.
  • Flexibility. Make large batches or small, depending on your needs.


How it works:

  • Choose your roast and grind size. Unlike immersion, you can grind all the way down to fine or very fine particle size if you prefer.
  • Place your chosen grind into the BrewBomb.
  • Connect your water source.
  • Use the control panel to choose your remembered brew profile, or enter the parameters of your brew, including flow rates, and anticipated brew time.
  • Adjust the spray nozzle to get optimum extraction pattern.
  • Start brewing.
  • Monitor the cold brew for your brew parameters and flavor, until you are done.
  • Dispose of grinds, clean and repeat the brew.

Immersion Tanks.


If you prefer the traditional immersion method of cold brewing coffee, Stout Tanks has a number of options for you, from 30 gallon batches up to 300 gallon batches. Every brewer has their own personal preferences for immersion brewing process. We can provide tanks with false bottoms to help filter out the first stage of coffee grounds, or we can provide conical tanks that allow grounds to settle to the bottom of the tank. We can provide tanks with insulation to maintain constant temperature, or we can provide glycol jacketed tanks that will allow you actively manage the temperature of your tanks to keep your cold brew at your exact temperature.


We can also provide pressure rated tanks that allow you to start the nitrogenation process. Our pressure rated tanks are designed to accept nitrogen under pressure at cold temperatures which allows your cold brew to nitrogenate more quickly. Most brewers finish nitrogenating in kegs, which we can also provide.


How we got into the cold brew business:

Mashing in at 5:30 am, coffee is a necessity. Spending all morning next to a boiling brew kettle, and cold brew coffee is more than a luxury.  And we are from Portland, Oregon, home to artisan coffee and craft brewing alike.  We’ve been drinking cold brew on tap before it was cool.  As the cold brew industry has grown, from the straight-up still versions all the way to flavor infused “nitros”, we’ve seen the need for the same quality of equipment in the coffee industry as in the craft beer industry.  With our experience and obsessive engineering, cold brew coffee fits perfectly with our company’s skill set.


Stout Tanks and Kettles’ cold brew coffee equipment is designed to make your business more efficient. With built-in stainless steel fine-mesh filters, a variety of batch sizes, optional glycol jackets, thermowells, tangential side ports for gentle circulation, optional pressure capability, and commercial clean-in-place (CIP) systems, your Stout Tanks and Kettles cold brew equipment is easy to operate and maintain. Our triple-layer filtration systems remove particulates down to 1 micron, and make filtering easy and precise.

How cold brew coffee and craft beer go together


Cold brew is where the craft beer and coffee worlds converge.  The craft brewery and cold brew coffee consumer are often the same person.  They value craft, flavor, and skilled local production.  Craft brew consumers frequently value a high-quality coffee in the morning.  Cold brew consumers often enjoy a flavorful craft beer in the evening.  Our brewery customers often add artisan coffee to their taprooms to drive traffic early in their day.  Coffee shops are adding kegerators for cold brew coffee and taps for craft beer to give their customers more options late in the afternoon.  At Stout Tanks and Kettles, we provide all of the equipment and expertise to make your cold brew expansion successful.


Lagers and ales ferment at precise temperatures, and hops are added to beer at the right moment to preserve the fresh aroma.  We understand how to brew your coffee at the right temperature and time to make the best cold brew possible.  Whether it is barley grains or coffee grounds, you will be able to engineer your best brew yet.  


Commercial cold brew coffee production

Coffee has over a thousand separate chemical compounds that can affect flavor. Each reacts differently at different temperatures. The art of roasting lies in the Maillard reaction, which converts starches and simple sugars into complex compounds, each with distinct aromas.  The origin of the bean, the temperature and time of the roast, the size of the grind, and nature and temperature of the water can all influence the flavor profiles of cold brew.  Our large batch cold brew coffee brewing systems are commercial grade and can help you take your cold brew business to the next level.  We support large scale roasters as well as independent roasters through the entire brewing process.  Our commitment to quality means our equipment warranties, team expertise and support are paramount.



The systems are designed with coffee shops, roasters, restaurants, craft breweries, brew pubs, and tap rooms in mind.  This clean, easy way of brewing with stainless steel tanks and kettles will make you gladly forget the messy plastic buckets and cheap filters. Instead, our professional grade equipment will accommodate your brewing needs and keep your product sanitary without the mess.


Your initial investment will have you brewing more than you thought you could, with ease.  Instead of dealing with the hassle every day of managing clunky, difficult systems, our 100+ gallon systems can get you started on still and nitro cold brew options.
