Dual Valve Drip Coffee (DVDC)

A very unique double valve cold drip coffee tower that allows you to meticulously extract coffee to your personal taste.

State-of-the-art dual valve drip coffee tower beautifully designed to not only make great coffee, but also it's been known to start great conversations wherever it's displayed.

Tower drips ice cold water over the grounds. This slow dripping of water gives you much more control over your brew and the strength of your coffee. You’ll also be able to watch as the coffee is brewed allowing you to increase or decrease the rate of flow for better results.​

Long Shelf Life - Refrigerate cold brew coffee anywhere between 7-14 days after it is brewed.   

Keeping in line of our philosophy of our products, the Dual Valve Drip coffee tower is available in wine barrel stave model and one in aircraft grade anodized aluminum. 

Each Tower includes:

  • 3 Glass Chambers
  • 3 Glass Lids
  • 2 Drip Valves
  • 1 Reusable Stainless Steel Filter
  • 1 Reusable Micro Stainless Steel Filter


 

 

With so many types of coffee makers on the market today, there isn't a "one-size-fits-all" for everyone. We've designed a very unique dual valve cold drip coffee tower that allows you to meticulously extract coffee to your personal taste. The dual valve system makes it possible to slow drip your ground coffee beans over a period of time (usually between five and twelve hours). This will allow you to enjoy your brew for at least two weeks (if you keep it in the refrigerator).

DVDC is a state-of-the-art dual valve drip coffee tower that is so beautifully designed that it not only makes great coffee, it's also been known to start great conversations wherever it's displayed.

This is one dual valve drip coffee tower you will never want to hide away.

 

We studied various coffee drip systems and wanted to design a dual valve drip system that would  appeal to a large majority of coffee connoisseurs. We've taken all of our experiences into account and created the first slow-drip coffee maker ever to feature adjustable dual-valves. The two models are called:  Sonoma and Classic

Sonoma Tower:

Made from upcycled Sonoma County wine barrel staves preserved in world class wine for months and even years on end. We rescue them from wineries and give them new life.

Each barrel stave's story is told through the unique nuances in its wood; a direct result of the differences in the winemaker's specifications. The effect is simply stunning. It enhances the natural beauty of the grain with rich, bold colors that vary in intensity and texture, making every stave slightly different, so no two Sonoma coffee towers will ever be exactly the same.

 

Classic Tower

Made from aircraft grade anodized aluminum, two brushed aluminum circles and two adjustable stainless steel drip valves. This tower embraces the understated beauty of modern design with sleek streamlined curves to give it a minimalist touch.

 

LED Circle Lighted Tower

We have designed an both towers to have the option of including a LED circle that lights up the tower.  You could light the tower up when brewing coffee, tea or simply use it for a beautiful night light when not using the tower to brew.

Dual Valves: 

Each tower has two valves made with extra durable, rust-resistant stainless steel which precisely control the drip of water starting at one drip per second.  One drip valve to slowly drip from the ice/water chamber into the grounds chamber and the unique second valve to control the flow of the extracted steeping time into the collection chamber.

 

 

 

"Baristas make cold brew by soaking coffee grounds in room-temperature or cold water and then let it sit and steep like tea for hours or even days. Then they strain the resulting coffee “tea” from the sludgey solids. Cold brew is taking the world by storm because it often has a deeper, less acidic and more subtle taste, and is more concentrated than conventionally-brewed coffee. It’s also a refreshing way to get your caffeine fix on a hot day." News on Business Insider

Cold drip coffee takes somewhere between 3 to 12 hours. The benefits of using ice cold water compensate for the longer brewing time. Cold drip coffee barely oxidizes (when refrigerated) making it easy to taste the delicate fruity flavors in used coffee. It also has lower acidity and less bitterness in comparison to hot coffee brewed with the same beans due to the absence of oxidation.

Slow Drip

 

Faster Drip

 

Quality materials handmade and crafted in the USA in California,  include finished wine barrel staves, aircraft grade aluminum, brushed aluminum circles and adjustable stainless steel drip valves. We are committed and proud to handcraft this dual valve drip coffee tower in California.

Distinctive Flavors

The slow cold brewing method will allow you to taste fruity flavors combined with a chocolatey aftertaste. This method of brewing has been known in Asia as “the wine amongst coffee”. When brewing a hot cup of coffee the aromas you smell evaporate into thin air and are lost. With our cold brewing method, the aromas are preserved in the elixir releasing an explosion of taste in your mouth. Because our slow drip method is perfect for filtering out  fruity flavors of the used coffees, we prefer to use light roasted coffees. This will let you taste more of the original flavors of the used coffee that would be overshadowed in a darker roasting profile. 

Preparing the DVDC tower and selecting the right grind of coffee.

measuring grounds

The second step is preparing your DVDC tower for the brew. Place the reusable stainless steel filter in the bottom of the middle glass chamber. This filter will make sure you have a clear cup and will prevent the coffee grounds from entering the drip valve. The amount of coffee used will partially determine the strength of your coffee. As a venture point: we use about 2 gm of coffee to 1oz of ice water. Obviously more coffee will provide you with a stronger cup. The strength of your coffee can also be tweaked with the grind you use for your coffee. The grind we use is in between the grind used for filter coffee and the grind used for French press. Next, place the fine reusable mesh filter on top of the coffee grounds. This will ensure an even drip.

Filling the top water chamber

fill water ice chamber

Water and ice are placed in the top chamber. The top chamber holds 20 oz. of ice/water. The amount of ice you should put in your water depends on the temperature of the room you’re brewing in and the drip speed you have selected. Because it’s the icy water that cools the coffee grounds, the basic idea is that the final piece of ice will have melted near the end of the brew. For a room temperature of 20 degrees Celsius (68 degrees Farenheit) and a brewing time of 6 hours we use 50% ice and 50% water. When brewing longer (up to 12 hours) use more ice at a slower drip. When brewing faster or in a cooler room you can use less ice and more water.

Selecting the right dripping speed 

drip speed

The last factor is the dripping speed. You can adjust the dripping speed by turning the valve at the bottom of the water chamber. As a starting point you can set you the DVDC tower to drip approximately 1 drop/1-1.5 seconds. Due to the changing water pressure in the DVDC tower, a full top reservoir will drip faster than a top reservoir that is half full or almost empty.  

Steeping

The beauty of the Dual Valve Drip Coffee tower is that it allows you to steep your coffee to your desired taste.  Then cover and release the elixir using the second valve on the coffee grounds chamber.  Once you are happy with the taste cover the elixir and refrigerate.

Prevent oxidation

Once you have steeped your coffee and have dripped it into the extraction chamber, it is now ready to be be covered with the provided lid and placed in the refrigerator. When coffee warms up in a unsealed container, it will start to oxidize and thus lose flavors. Once in the refrigerator, your coffee will store for at least two weeks. As with good wine, this method of coffee making will ripen further once bottled. Your bottled coffee will taste best after three days in the refrigerator. Once you taste the enhanced flavors of your coffee, you’ll wonder how you ever lived without it.
