Video: Making Cold Brew Nitro Coffee

Cold brew coffee is sweeping the world for a bunch of reasons

  • Less acidity - easy on the stomach
  • High caffeine - up to 6x an espresso
  • Smooth flavour - much less bitterness
  • Easy to drink black so no dairy or nut milks needed therefore lower calories.
  • Makes perfect coffee based alcoholic drinks like espresso martini
  • When poured using nitro it comes out with a creamy texture despite having no milk in it.
  • Nitrous oxide give a slightly sweet flavour, a creamy head and can be used instantly.
  • Pure nitrogen must be left for a while to absorb into the liquid but then pours with cascading head like a stout.

This keg system makes it super easy to have nitro cold brew coffee or cocktails on tap at home. Check out the video to see how easy it is!



THE NITRO KEG PACKAGES INCLUDE:

The iKegger Coffee Spear

  • This is the part that screws into the mouth of the keg
  • It has an attachment for the coffee tap
  • A 75 psi safety pressure release
  • A N20 bulb inlet valve with bulb cover

The Nitro Coffee Tap

  • This stainless steel forward sealing style tap is designed for high pressure usage.
  • It's long tapered spout has a sieve like plate inside that forces the coffee through fine holes to make the dense foam / head.

Optionally Add A Vessel To Suit Your Needs

  • There is the choice of 2L, 4L, 5L and 10L Mini Kegs
  • 2L and 4L Insulated Growlers (Stay cold all day without ice)
  • 1 liter of the volume is not usable for coffee / cocktails as you need space for the gas.

trouble shooting nitrogen keg packages - coffee, cocktails etc.

AFTER LEAVING OVERNIGHT THERE IS NO GAS LEFT

  1. The more empty space in the keg the more gas you need to pressurise it. Was the keg pressurised before you left it, or did you just put some gas into the empty space? (pull the release valve briefly, gas should rush out)
  2. Liquid absorbs the gas. Pure nitrogen especially will dissolve into the coffee, this is what gives it the cascading bubbles effect when poured. Pressure will drop as the gas dissolves into the liquid.
  3. You have a leak. Check all connections, nuts etc are tight and not leaking (put soapy water on any suspect spots or hold the pressurised keg underwater to look for bubbles)

THE TAP DRIPS AFTER POURING

  1. With stout / coffee / nitro spout the tap will always drip a little after pouring. The premium stout tap will drip the least as it's designed differently and specifically for nitro. The spout of all nitro systems has liquid in it still when the pressure pushing it it taken away (the tap is closed). The remaining liquid will slowly drip through the tiny holes in the spout. A drip tray or mat is a good idea.
  2. If the tap continues to drip for a long time after pouring and you think it's actually a leak you can take them apart to check everything is correctly assembled inside. For a parts diagram see here for the Chrome Tap on Plastic Disconnect and here for the Stainless Flow Control Tap.
 

If the drip is coming from the ring securing the tap to the shank adapter and disconnect then ensure you use the included tool to tighten the ring of the tap shank adapter onto the tap.

If there is a leak between the cone shaped part of the tap shank adapter and the liquid disconnect make sure you mesh the teeth of the tap and cone and use the tap as a lever to tighten that joint.

foam DISSIPATES very quickly

  1. Contents not chilled, make sure all liquid is chilled as much as possible. Nitrogen gas does not cool the contents of the keg, you still need to chill them in a fridge or ice. The insulated growlers will maintain the temperature for a long period but the contents still need to start chilled.
  2. Contents not shaken enough. After injecting the gas you need to give the contents a good shake to dissolve the gas into it. You can hear the sound of the liquid change as it becomes frothy if you listen.
  3. Alcohol percentage is too high. Shaking straight vodka (or water) will never produce a foamy head. In one of our videos we suggest 1/3 of each coffee, vodka and Kahlua for a martini however in further experiments and talking to bartenders we think 50% coffee, 25% each of vodka and Kahlua gives better results.
  4. Coffee blend has a high oil content. Like oil on rough seas, coffee beans with a high oil content will prevent the foam from staying around long.
  5. Not enough gas pressure. You need minimum 40psi of pressure to force coffee through the spout and have the desired effect. We would usually put 9L of coffee in a 10L keg then inject one N2O bulb and shake well. We'd then put in one more bulb and begin pouring, once the flow slowed down we'd inject another bulb to continue. If using the pure nitrogen bulbs you will need more than this, they only contain 2g of gas as opposed to the N2O bulbs which have 8g

Flow Slows Down To A dribble or stops completely

  1. Pull pressure release valve, if no gas comes out put in a new bulb or two
  2. If gas comes out the pressure release, unscrew the spout of the tap and check that the metal plate is clean and the 5 tiny holes are not blocked
  3. If the metal plate and holes are clear take them out and try pouring with just the white plastic piece in the spout. If it is restricting flow too much you can cut a little notch in the side to allow more liquid through or contact us for a replacement if you are not comfortable doing that.

Which Gas Should I Use?

We provide 2 different gases for use when producing coffee, cocktails etc. These are pure nitrogen (N2) and nitrous oxide (N2O). Either can be used, it's up to personal preference however they behave slightly differently and it may take some experimentation to get the outcome you are looking for.

  1. Pure Nitrogen (N2) is available in a few different forms. We sell 2g disposable bulbs in packs of 10 (for use with the bulb injector packages). We also have 2.2L disposable gas bottles (with around 280g of Nitrogen) that use our M10 threaded regulators. You can also get a gas bottle filled with nitrogen by your local gas supplier and use one of our dual gauge regulators that usually have a type 30 thread on them (however you will probably need to have this changed to a type 50 thread which is what most nitrogen bottles are in Australia).
  2. Nitrous Oxide (N2O) we only sell in 8g disposable bulbs (the same size as the 2g N2 bulbs) so you can use either option in the bulb injector system.

I personally use the N2O bulbs for all my nitro drinks for the following reasons

  1. They give immediate results. You simply inject the bulb(s), shake and pour. Using pure nitrogen you will get better results after leaving for at least a few hours for the gas to dissolve into the liquid.
  2. You use less bulbs. 8g of N2O is in the same size and price bulb of N2 that only contains 2g. You need many more bulbs to dispense the same amount of liquid using pure nitrogen than using nitrous oxide.
  3. I'm generally pouring either for myself (I keep a keg of cold brew next to my desk at work) or I'm using it at parties for espresso martini so I don't care about the cascading bubbles which look nice visually (see below).

Some of the coffee roasters / cafes that we deal with do not like to use N2O however for 2 reasons.

  1. We've been told that N2O imparts a slight sweetness to the beverage (I don't notice but I'm not a coffee person).
  2. The foam that N2O creates is not so much like the cascading bubbles of a Guinness but more the dense head of an espresso martini. If you are specifically after the cascading bubbles you need to use pure nitrogen.

How Many Bulbs or What pressure gas?

These are all a matter of personal preference depending on what you want to achieve with your system and will likely require some experimentation on your part as things like coffee blend, strength, type of gas, pressure used, temperature served at, length of shaking and resting time will all alter the final product.

In general I personally use the following method:

  1. Make a batch of cold brew coffee using 80g of course ground coffee per litre of water infusing for 12 hours in the fridge before straining.
  2. Pour the chilled, carefully strained cold brew into a keg leaving 1L of free space (4L of coffee in a 5L keg for example).
  3. Screw on lid and inject one bulb of N2O before shaking well. I listen for the sound to change as the drink becomes frothy in the keg.
  4. Inject another bulb to provide plenty of pouring pressure
  5. Attach tap and pour as needed, you can detach the tap to store the system when not needed.
  6. If the flow slows down, inject further bulbs as needed (I find that 2-3 bulbs is plenty for the 5L keg, 3-4 bulbs for the 10L keg).

If you are using pure nitrogen (N2) bulbs you will need to use more bulbs than this. I personally have not had enough experience to say how many, but on the packet it says one bulb per 500ml of coffee (I think that is an over estimation though).

If you are using a bottle of N2 gas then I attach the gas disconnect to the keg and turn the pressure up to 45psi (3bar). Shake well and then leave to sit for a couple of hours with the pressure still set to 45psi. You will also pour at 45psi so just check how the brew looks after a few hours by pouring a small amount. You can always speed up absorption by shaking the keg for longer or more vigorously.

Great piece of equipment

Super sturdy piece of equipment and easy to use. Brought this at work to make 1.5 liters of cold coffee to beat the heat wave, everyone was impressed with smooth, creamy and foamy coffee ! Also works well with beer with an appropriate style, in my case a homebrewed white stout turned out great !

Great product

Love it, only downside is the size of the insulated keg. But you can't have the cake and eat it too.

Good products and great support

I had a good experience with the iKegger team. As I was trying to use the items I bought for Nitro coffee I had a few follow-up questions and got great information from them and was really impressed with the speed of responsiveness. A great company to order from

At iKegger we genuinely love what we do.

That's why we do it!
