Ok, I purchased the Royal Brew over their competitors based on watching videos on Youtube and Reviews. I know people have complained about a lot of leaking systems and was concerned about this. I purchased the 1 Gallon Keg System. I use the Toddy Cold Brew to make my concentrate and fill the tank to 96oz with 4 (2 gram Nitro Cartridges) I have batched 4 tanks this past week and not once did the Royal Brew Leak at all. When I first received delivery from Amazon on this product I contacted support at Royal Brew through their online Chat and expressed my concerns on having issues with my first attempt to make Nitro Coffee with their system, The support staff answered all my questions and sent me video links on how to set up for my first batch, Its very easy to use the Royal Brew, you just have to make sure that you use the correct O-Ring between the Stout Faucet and Steel Spear Assembly, then fill the keg with your Cold Brew and tighten assembly with the wrench they give you and you are set to start charging the keg with the Nitrogen 2 Gram Cartridges as the instructions state. I posted a video using a Starbucks Coffee Cup to demonstrate how the Royal Brew delivers a true nitro cascading coffee. The Nitro Coffee that the Royal Brew is the best there is. Now I am saving all this money that I have been spending at Starbucks. The Royal Brew is tremendous system. I am so glad that I went with the Royal Brew System.

I bought this for my husband for his Christmas present when I noticed he was missing nitro brew floats that we enjoy at the beach. He has really enjoyed getting to know how to use it, and making his own cafe quality nitro brew at home. He even mentioned to me about the "leaking" some people claimed they were experiencing and explained that it was simply residual coffee in the nozzle. He tapped it a few times to disrupt the air bubble that kept it inside and it emptied out. We have had no leaking at all. He did the math on how much nitrogen he needed for the amount of cold brew, and he gets inches and inches of foam on his. I suppose those who do not get the foam are simply not adding enough nitrogen, or they are not adding it in the correct time intervals.
I will say the only complaint that I have is that this was touted as an American made company and when I opened it up to wrap it, it said "made in China" on the box. Other than that, completely pleased with this product.

This is my first nitro coffee maker, but I'm an old hand to homebrewing. I've done many, MANY gallons of wine and beer. This is, by far, the easiest experience I've ever had with a brewing system. Assembly was a breeze. Instructions were easy to understand. The quality of the product is superb. The only issue I've had with it is the same one everyone's had with it. It drips a little bit after you pour a glass, and they gave me a little rubber cap to stop that from happening. I'm looking forward all the nitro cold brew I can stand this summer. I'd 100% recommend this to anyone thinking of getting into nitro cold brew at home.

Edit: I keep referring to this as a brewing system, and it's not. It's a keg. And it works flawlessly. It produces the creamiest nitro coffee you've ever had. And don't be afraid to experiment. I was using this horribly bitter Ethiopian Single Source for my morning coffee, and as a pour over, it was awful. I ground the rest of the bag and cold brewed them for 12 hours. Then I diluted that 1 to 1. Put that through the Royal Brew nitro keg, and that coffee tastes completely different. So much better than the pour over. This keg has literally changed the way I think about coffee.

We have now owned this amazing Nitro Cold Brew Coffee Maker for one month. We loved it from the start but I wanted to have it for a little while so I could provide an adequate review. I thought maybe my excitement over this new treasure would fade, but exactly the opposite is true. I absolutely love having nitro coffee available at my fingertips every day. It works beautifully, it is easy to clean and fill, and we could not be more pleased. It truly does make cafe quality nitro coffee. We did need to do some rearranging to be able to put the Keg in our refrigerator so we could keep it there for daily use, as it’s quite substantial in height, but it was worth a little juggling to be able to have this wonderful treat every day! We use only two 8 g nitro Ultra Pure Whip N2O for the large sized keg. This is truly a bit of a luxury purchase, but if you like nitro coffee, you will not be disappointed. Use all the money that you have not spent on purchased coffee during the past six months for this gem. Put it on your wish list or ask Santa to put this under your tree!

Missing an o ring so the tap wouldn’t work. And now my only option is to return the entire thing.

Opening the box, this Original Royal Brew Nitro Cold Brew Coffee Maker looks pretty awesome. Black powder-coated growler, stainless valve and infuser, simple assembly. Upon closer examination the black growler bottle/tank is not double-wall insulated! The valve assembly works great and appears to be well made, should last a very long time. But the fact that its only a single wall tank, it will not keep it's contents cold for very long outside of the refrigerator. But the size of this thing when assembled, almost 24 inches tall, it is very difficult to find space in the refrigerator.
