Dreamt up by a husband and wife team in Boston, the patent-pending Cold Brew on Tap was born out of our personal need for an easy-to-use cold brew maker that was big enough to get us through the week!
We've made a bunch of customizations and adaptations to bring this working prototype to life. If we get fully funded we'll let our backers VOTE on the design that goes on the glass dispenser!
Zero expertise and less than two minutes of simple prep is required to brew a batch of cold brew. The 12 inch tall Cold Brew on Tap fits perfectly on most fridge shelves and can make between 1 quart and 1 gallon (16 helpings) of cold brew - ready to serve up right from your fridge!
The Cold Brew on Tap is the first and ONLY cold brew maker that currently exists on the market that makes more than 6 cups of ready to drink cold brew at a time. It’s perfect for making a week’s supply of cold brew for a household of one or two people (depending on how caffeine addicted you are!).
The Cold Brew on Tap takes advantage of the high-quality glass construction of an extra large mason jar and has a ton of awesome features!
Now you can skip your daily morning stop at Starbucks and start saving time and money with the Cold Brew on Tap.
Imagine spending just 15 cents for a cup of cold brew versus the $3-$4 it costs you at a coffee shop and having complete control over the taste and strength of your cold brew!
So, how did we dream up the Cold Brew on Tap?
As a married couple living in Boston, we're surrounded by amazing but expensive coffee shops that were doing a number on our wallet. That's us below!
When we realized that our daily coffee shop visits for cold brew were costing us more money and time than we wanted to admit we started looking for alternate solutions.
Unfortunately, there wasn’t one!
What we couldn’t figure out was why every Cold Brew Coffee maker we tried for in-home had issues!
We tested a lot of different methods and contraptions on the market and finally settled on a design and functionality that was stylish, on trend, easy to use and convenient to store and serve from.
The Cold Brew on Tap is such great quality that we even have a lifetime guarantee!
Now we start our weeks by spending less than two minutes prepping our Cold Brew on Tap on Sunday morning. It’s ready to go on Monday morning and one batch makes enough coffee to get both of us through the week.
Every morning before work, we just open the fridge, turn the spigot on the Cold Brew on Tap, fill up our thermoses and get going!
Why Choose Cold Brew on Tap?
Get Complete Freedom and Control Over Your Coffee
With the Cold Brew on Tap, you’re in total control of the brewing process - from how much cold brew you want to make to the flavor of the coffee to the strength.
Customize your cold brew according to the taste by using your favorite beans or coffee grounds. Use more coffee grounds and more water if you want to make a big batch and increase your brew time if you prefer stronger coffee. No matter how you brew it the process is quick and easy. It takes less than a minute to prep a whole batch of cold brew that will get you through the week!
Using the Cold Brew on Tap gives you complete freedom and control over your daily cup of cold brew and you should experiment with what suits your taste best!
INCENTIVE! If fully funded backers get to choose the design on the glass dispenser!

Upgrade your pledge level and get our set of two high-quality glass mason jar coffee mugs complete with 1 seal tight travel lid, 1 straw lid, and 1 stainless steel straw. This set is perfect for taking your cold brew on the go (with the sealing lid) or for sipping cold brew from your desk or on the couch. The handle makes it easy to carry and transport and the stainless steel straw keeps your cold brew feeling cool and refreshing.
Here is the initial brainstorming phase of Cold Brew on Tap that we started in Spring of 2017!
Product Design Iterations
It's important to note that the pictures you see are not the exact product you will receive, since it's a prototype. If we hit a certain funding goal we'll have enough money to open a new mould for the dispenser design and will let backers vote on what design THEY want to see on the dispenser. Handles on the dispenser are also part of our "dream" design - but we need YOUR support to make that happen!
1. Coffee Filter
Here are initial sketches of the different coffee filter designs we were considering that included a conical shaped filter, a shorter filter and a filter made out of stainless steel.
We narrowed it down to one design, after testing a plastic/nylon mesh version, a more porous stainless steel version and a mesh filter that was pieced and held together by stainless steel strips and screws. We finally ended up choosing a large cylinder shape that would extend almost to the bottom of the drink dispenser (ensuring it holds enough ground coffee) made out of very fine 150 micron mesh.
We customized the shape and size of the filter so it would fit the unique wide mouth opening of the one gallon drink dispenser AND extend far enough into the vessel to allow for brewing smaller amounts of coffee.
2D CAD File of our chosen filter design:
3D CAD File of our chosen filter design:
Here's a further 3D CAD file showing the filter and how it was customized to fit into the 1 gallon glass drink dispenser. The filter had to be shaped so that it would fit snugly into the dispenser AND accommodate the lid and seal airtight without any space or gaps.
WORKING FILTER PROTOTYPE
We chose 150 micron fine mesh material, over plastic or more porous stainless steel to ensure very fine filtration and smooth coffee with little to no sediment and coffee grounds in it.
We knew we wanted the lid to be airtight since we tested so many already existing cold brew makers that didn't seal and let coffee get stale if not consumed within a day or two.
We initially tested a plain metal lid but found that it was insufficient for sealing out air.
In addition we tried a lid with silicone and the finally a lid with foam on the inside that created a more airtight seal.
3D CAD drawing of the final lid construction we chose. High quality foam was more economical and created a more airtight seal.
WORKING LID PROTOYPE
Here's an image of the prototype lid with a foam sealing layer that we ended up choosing due to it's better performance and economical cost to keep the price of Cold Brew on Tap affordable.
3. Spout with Mesh Screen
Smooth, sediment free cold brew is a must have for us. That's one of the reasons we ended up choosing a 150 micron mesh filter. To ensure totally debris free coffee we wanted to create a second "safeguard" against loose particles, sludge and coffee grounds so we customized a small mesh filter to fit on the spout of the dispenser.
3D CAD drawing of that modification.
The mesh covering on the spout further filters out any loose coffee grounds from getting into your mug AND blocks sludge that collects at the bottom of the dispenser from passing through the spout.
WORKING MESH SPOUT COVERING PROTOYPE
Here is a final image of what the mesh looks like on the back of the spout.
4. Glass Body
It was important to us to keep the trendy, stylish and vintage feel of a mason jar for the body of this cold brew maker. Please keep in mind what you see in our current images and in the video is a prototype. The final version will very closely resemble this but we are going to offer our backers the chance to VOTE on the final design on the front of the dispenser.
We've tossed around ideas like wording that says "Coffee Station" or "Cold Brew on Tap"...or a simple piece of chalkboard that allows users to write on the dispenser. This is an expensive customization that will only be made possible by your support!
In our final design of the dispenser body, another "dream" item is to have handles on the dispenser to make transporting in and out of the fridge (for when you need to clean your Cold Brew on Tap or make new batches) easier and more convenient.
Here's a 3D CAD file of our design for the dispenser with handles:
A prototype of this doesn't exist yet since it's one of the most expensive moulds to open and we need to raise a certain amount to bring this exact iteration to life.
Risks and challenges
A fully functioning prototype of the Cold Brew on Tap has already been completed and we've been using this prototype for the past few months working out any kinks and improving functionality. If fully backed we expect to have mass production of Cold Brew on Tap completed by November.Learn about accountability on Kickstarter
