Back out your regulator before you turn on the bottle valve! Your regulator may top out at below the kegs rating, but if someone is using a 500psi regulator, you could blow up a keg. Start low and adjust up.
It would be cool to modify a keg by cutting & welding an airtight dosing mechanism into the bottom and use the keg for storing coffee beans. It would increase the shelf-life by a lot.
Questions on preparation of coffee: Is the coffee hot or cold brewed before adding to the keg, and what is a suggested recipe before transferring coffee to keg?
3 pounds of coffee grounds for 3 gallons of water for concentrate or 1/2 to 3/4 lbs of grounds per gallon. Its up to your tastes also. Making concentrate will allow you to add water to get the right ratio you like per glass that's poured.
@Prima Coffee Equipment after the Nitro infusion on the time & psi you mention, do you close the Nitro tank? Or does it stay open to keep serving until the keg is empty?
Once I add coffee to the small keg, how long will it last in the kegerator before it goes bad? Also, someone told me I need a mini-nim in order to make the coffee with nitrogen flow properly.. is that true?
Hi Prima, Thanks for the video. I am using this to check what I need when buying the similar setup as you show in this video. Question: How much liquid/nitrogen ratio is needed in each tank? If I have a 3 gallon tank, how much of that is coffee concentrate? Thanks in advance!
Hi Adam. Apologies for the late reply, we've been caught up in the Black Friday/Cyber Monday hubbub! Corny kegs like this will be under continuous gas pressure controlled by the regulator at the tank. So, they can be filled to their max rated capacity and the gas pressure will be the same as when they are nearly empty. A full keg has less gas by mass than a less-full keg, so allowing some time for conditioning to let the gas dissolve into the coffee is important, but otherwise the flow rate and head should be fairly static as you run through each keg. If you have other questions our sales team would be happy to chat any time! sales@prima-coffee.com
It certainly could, you'll just want to be diligent about cleaning the lines and spouts. You may also want to invest in a glycol chilling system so the milk does not warm up between the keg and the spout.
In my state, I only found a gas bottle containing 95% nitrogen and 5% oxygen. Can it be used to make nitrocold brew coffee, or does it have to be 100% nitrogen gas?
We used and prefer pure nitrogen. Carbon dioxide can do funny things to coffee's flavor, as it creates carbonic acid when dissolved into water-based solutions. You could try to account for that extra acidity by adding a sweetener or some kind of buffer, but in production it's usually easiest to just brew and keg without messing with the coffee too much. That being the case, pure nitrogen will have no impact on the flavor, and while the foam will be slightly reduced the overall result is quite similar.
That's what I figured. A CO2 blend works best for Beer but not for coffee. At a local roastery here they used a blend and it had a weird carbonic bite that did need loads of sweetener to tame. Makes sense to use 100% Nitro. Thanks for the explanation. Cheers.
Hi- i know this video is a little old but I am looking for help! I did this step by step and seem to have leaky ball and lock valves that I got off amazon. Seems to be a common issue, does anyone have solutions?
Hi, Albert. Where is the leak coming from? If it is coming from one or both the posts (on the keg), the O-rings may need to be replaced or the poppets may need to be adjusted or replaced. If the problem is indeed in the ball lock itself, though, the best bet is to purchase a new ball lock quick disconnect from a reputable manufacturer. Good luck.
Hi, I have a question about using keg system to prepare Nitro Coffee using a 4-kilogram nitrogen gas cylinder with a pressure of 40psi. What quantity can I prepare until the nitrogen gas cylinder becomes empty?"
@@primacoffeeequipment I am sorry, there is a stage that I did not understand, which is when pumping nitrogen gas into the keg. Do I close the gas bottle directly, or is there a specific time, or does it close when the keg is empty?
@@djelloulzaidi1016 Really the only time you need to shut off the gas or "close the gas bottle" is when you are changing kegs or gas tanks. When the keg is empty, there will just be gas coming out of the tap, then you would close off the gas and switch out kegs. If the gas runs out, you would close he outbound valve on the gas regulator, then remove the nozzle from the spent tank, then put the new tank on and open the valve and you are good to go.
Yes, you can chill kegs on ice and they'll still dispense properly as long as they are stored upright. You may want to check in with your health department to ensure they allow beverages to be stored and served this way.
Awesome video guys! You've mentioned brewing coffee using the Toddy, may I ask what ratio you guys think tastes best for Nitro Coffee? Thanks a million, Napo
It depends on the coffee you're using, for sure, but for cold brew we often like around 90 grams of coffee per liter of water. We've got a whole slew of recipes here: prima-coffee.com/blog/what-everyone-ought-know-about-iced-coffee-cold-brew-31371
Can you make hot coffee, pour it in the empty keg and let it cool? And use that? If so, how long, once it's cooled and in the keg box, will it last for..before it goes bad?
We've had good luck using welding supply shops, as they will have a variety of gases available and often rent and exchange gas cylinders. Beer supply stores will also often have nitrogen and CO2, but may only be able to fill cylinders rather than rent them out.
No, you need to keep it connected. As you dispense coffee, the volume of the empty space in the keg increases, which will result in the gas pressure inside decreasing. So, you need to keep the gas bottle connected to maintain pressure as you dispense.
@Jeroma you can purge the air out of a keg and pressurise it, then store cold. If you do it right, you can store it in a cooler for 2-3 weeks without noting a flavor change. You would need to clean your lines if you are swapping between beverages. Cheers!
Prima, I need help. I got everything setup yesterday and let NO2 condition overnight. Came home after work and connected the "out" line and noticed no solution came up through the line. Come to find out my NO2 tank is empty (both gagues are reading zero). Does this mean I have a leak somewhere? I only had the NO2 tank connected for 24 hours. Also I only filled my keg (3 gallon) with 0.75 gallon of coffee, is that an issue? Do I need to have more coffee in the keg? Any help would be great, thank you.
It's possible you've got a leak. Check all the fittings and seals - you can pour water over them to check for bubbling. Often the most likely culprit is a loose connection between the regulator and the gas bottle, but be sure to check your hose clamps and keg fittings as well. When filling a keg, capacity isn't all that important as they are designed to run until almost entirely empty regardless of how much liquid was present to start.
@@primacoffeeequipment After nearly 10 months of putting this off...I finally took another stab at nitro this past weekend and got everything setup and isolated my leak. With the leak fixed I now have Nitro coffee! YAY! However I am not getting any cascading action? Am I using too low of a psi (currently at 40) or is there something I am missing? Regardless of no cascade action, it tastes amazing and is extremely strong (I brewed 1.2 gallons to 24oz of coffee)! Thank you for your help!
Hey Todd! We've been able to source it from welding and gas supply shops, where it's commonly available in different grades. We suggest purchasing food or beverage grade nitrogen if available for the sake of purity and flavor, but ask your local shop what they have available and would recommend for use with beverages.
I want to ask you another question. So I'm also trying to make nitro tea. But so far I have been using the recommended psi for coffee, which most people says between 35-45 psi. But I'm not getting the creamy texture. Does anyone know what I should do? Thanks.
Two things you might try: the first is simply letting the tea sit longer, or agitate it more. This will allow more nitrogen to dissolve into the liquid and better create a foam when dispensed. Secondly, it may be that you need to brew a stronger tea. We didn't have any trouble nitrogenating normal strength drip coffee, but we did find we had better results when we increased the strength by using more ground coffee to brew with.
You probably don't want to use the stock bottle to hold your nitro. Though it's stamped that it can handle nitro pressures, the sturdiness of that tank is paperlike compared to purpose-made tanks - the potential for it to be compromised if dropped or knocked over is mind boggling... and you can imagine what 2200-3000psi will do to a tank with a puncture. Also - nitro if leaking has the potential to force oxygen out of small enclosed spaces... Safety first kids.
Thanks for the comment! We're sourcing our bottles from a trusted supplier and we're quite sure they're meant to be used specifically with nitrogen. Of course, if one is buying parts from other suppliers it would be wise to make sure they're using equipment meant for nitrogen as well. Cheers!
Great video however you forgot to release the air trapped in the mini keg. Oxygen should not be in the storage container because it will oxidize the flavors and produce that bitter taste most cold brew drinkers are looking to avoid. To purge the air simply pressurize the container and then use the pressure release tab to release the air out the container. Re-pressurize back to 30-40psi and your ready to go.
Hi Juan, we actually do this at 6:12 in the video above as well. You're right on - eliminating that extra oxygen in the keg will go a great length to slowing oxidation and does a good job of keeping the coffee tasting fresher.
@@primacoffeeequipment Question .... If i want to let the Nitrogen dissolve on its own , you suggested to let it sit for 8-10hrs . Do i leave the pressure Open at 25-35psi this whole time ?
The nitrogen in the video is plain nitrogen gas, N2, which makes up most of the air you breathe every day. It's perfectly safe to consume as part of a beverage. We do recommend sourcing nitrogen gas that is intended for food or beverage consumption, but some gas retailers do not make a distinction because all their nitrogen meets those purity standards.
@@primacoffeeequipment Speak for yourself fancy man I only breathe 100% pure oxygen! On the real though, I heard that a diffusion stone is necessary to use nitro. have you used one? is it really necessary to diffuse?
@@AD-iw4vy I'm not familiar with diffusion stones, but if you try to dispense coffee under N2 pressure through a standard faucet (like for carbonated beer) it would come out flat. A Stout Faucet (like they use for Guinness) must be used to create cavitation and incorporate the N2 into the drink as it exits the spout.
A kegerator is a refrigerator specially designed to hold beverage kegs, with lines and faucets for serving. They're most often used for beer, but as you can see they can also be used for coffee!
Back out your regulator before you turn on the bottle valve! Your regulator may top out at below the kegs rating, but if someone is using a 500psi regulator, you could blow up a keg. Start low and adjust up.
Can you elaborate more on this topic? I am new to the whole nitro tank world.
Hey bro how many kegs are you able to reload with coldbrew with one of those nitro tanks under that psi?
I just want to say thank you.
It would be cool to modify a keg by cutting & welding an airtight dosing mechanism into the bottom and use the keg for storing coffee beans. It would increase the shelf-life by a lot.
Hi, I have a 5-gallon keg. Is a 20 ft³ nitrogen tank sufficient, or do I need a larger one?"
Questions on preparation of coffee: Is the coffee hot or cold brewed before adding to the keg, and what is a suggested recipe before transferring coffee to keg?
ideally you’re using cold brew so presumably approx. 40° freedom.
i saw another video where they put the gas in the middle on the lid and say there is rod , is it different outcome than your set up?
How many pounds of coffee and gallons of water do you use to fill the 3 gallon keg?
3 pounds of coffee grounds for 3 gallons of water for concentrate or 1/2 to 3/4 lbs of grounds per gallon. Its up to your tastes also. Making concentrate will allow you to add water to get the right ratio you like per glass that's poured.
@Prima Coffee Equipment after the Nitro infusion on the time & psi you mention, do you close the Nitro tank? Or does it stay open to keep serving until the keg is empty?

Once I add coffee to the small keg, how long will it last in the kegerator before it goes bad? Also, someone told me I need a mini-nim in order to make the coffee with nitrogen flow properly.. is that true?
Whats the material of the blue coloured hose that was used with the regulator?
hay can I just put the sugar into the keg to make my coffee sweet while the Co2 comes in?
How many pound nos tank is that and how much nitro brew will it yield at the recommended psi
If you don't have the time to wait 8 hours, how long should you shake it to dissolve the nitrogen and condition everything?
If you shake a charged keg for a few minutes you'll get a similar result.
Where do u buy and refil the nitrogen. What size is that tank. Can anyone buy nitrogen tank's like ftom a welder ? . Thanks
Hi there! We believe this is a 22cu ft. tank. We refilled it with medical grade N2 at a local welders supply shop.
Where do you get refills for nitrous?
