Before I go further, I am incredibly happy with my purchase. I am able to make draft coffee and lattes with exactly the same taste and mouthfeel as from cafes. It's a little hard to fit in my fridge, so make sure you take measurements to find the ideal positioning. The build quality is very good, with solid hunks of heavy, stainless steel and robust gaskets. The whole thing is put together well with only a couple of pieces of plastic.The instructions are quite poor. They are difficult to parse, badly laid out, contain multiple typos, and are inadequate for making the best coffee. They mention attaching a gasket, something also mentioned in their YouTube videos, but it was not in the package, while another, different gasket came pre-installed. There are steps emphasizing the importance of cutting the hose to the correct length, but I instead received, like, a dozen pre-cut hoses that I just cleaned and used. The process was confusing.Nowhere is it explained that nitrogen has a huge effect on flavor. I knew this, because I have loved nitro coffee and nitro beer for years, but did not fully appreciate the magnitude of the effect until putting some off-the-shelf cold brew coffee into the keg. Cold brew is already very mellow, and the increased mellowing of the nitrogen makes the coffee taste almost like water. I strongly recommend making your own cold brew and using a slightly diluted concentrate instead of fully diluted coffee. The same goes for if you are making draft lattes, make the drink stronger than you otherwise would when consuming via another method.The instructions are also, strangely, contradictory with other pieces of documentation from Royal Brew. Some places recommend using a single N2O canister, whereas others say that the dual N2 canisters are ideal. I have tried both and can say, beyond doubt, that the dual N2 canisters produce a significantly better product. If you desire a product that is similar to what you would get from a cafe, you must use N2.Unfortunately, the process for using dual N2 canisters is one of the areas where the instructions fail. They simply say to repeat two steps for the extra canister but they do not provide the correct time frame in which to repeat these steps. Again, I experimented and can provide some insight. When you inject the first N2 canister, shake the keg and let it sit for a short time. You don't need to take a full hour, since all you want is for the liquid to absorb enough of the gas such that, when you remove the N2 canister, you don't have wasted gas blast out. If you attach the second canister shortly after injecting the first, you will lose quite a bit of gas from the first injection. After you have attached the second canister, vigorously shake the keg for a full thirty seconds. I let my keg sit in the fridge for an hour in one case and two hours in another and saw no difference in final product. One hour appears to be enough for the initial gas infusion. If your keg has sat unused for more than a couple of hours, make sure to vigorously shake the keg for thirty seconds before dispensing. The quality of the nitro when these steps are followed is excellent.Finally, I don't like the videos and photos of people drinking full beer glasses of beautiful, cascading nitro coffee. This is not a large keg. Maximizing quality demands that you absolutely do not fill the keg past the 75% mark, which means that you can only put 48oz in the 64oz keg, which means that it's enough for only three of those glasses. If you drink a lot of coffee through the day, or if you have company, you will hit the limits of the 64oz keg very quickly. I hit the limit on my second day with some friends and since preparation takes 90 minutes, it's not something you can just whip together when you run out. I strongly recommend anyone looking at this product to look at the 128oz version, even though its increased size will make the shaking step during preparation that much more difficult.All in all, while this is not super-easy, it is also not hard. And importantly, the final product is so good that I don't care about the process required to get there. I am glad that I chose this over the uKeg because, one, it was cheaper, but also because the external connection for the gas means that I am not beholden to the tiny canisters. I could theoretically attach a larger gas assembly, which is even more attractive if using the 128oz canister which requires four of the N2 gas canisters. That is neither here nor there, though. I am very happy with my purchase after only a few days of ownership.

I took a notice of the nitro cold brew craze over the last year and especially this summer when my girlfriend and my kids increased the frequency of Starbucks trips for this tasty sensation. I decided to get the royal brew home kit, which can fill up 4+ nitro cold brews which can last for about a week. I have had this kit for a bit over a week, and please understand I am a complete novice in this area and do not drink cold brew. I am only the at home barista for my ladies.1. The initial instructions are a little confusing, however there is a link to a video. One key thing I learned was to install one additional gasket provided when you first put together spigot, other than that it is easy to assemble.2. There are multiple directions on how much liquid you should put into the tank. I made 3 different batches over the last week and have been careful to put exactly 48 ounces of coffee into the container. I use a 64 oz measuring cup to ensure I get the right amount into the unit. (It would be great if there was some way to be able to see / measure how much water is in the container as it seems impossible to look at the level in the tank from the top.3. Cold Brew Concentrate: I found the cold brew concentrate creation the most difficult up front. There are many recommendations on-line and I am sure others are doing it better than me. I use a gallon container and then a food strainer with coarse ground beans of multiple types to make the concentrate. My girlfriend likes it strong and so we end up using nearly straight concentrate in the tank.4. Cream additive: During our trials we have tried both adding cream after and pre-mixing in the concentrate. Premixing in the concentrate is the preferred method right now. We are currently at 4 oz of cream with 44 oz of concentrate. I am sure we will continue to modify but that mixture seems to be working well.5. N02 or N2: N2 takes 2 cartridges with some time between each mixture, however really creates that creamy taste that most people are looking for. The consistency from the 1st glass to the end of the 4th glass does start to change the mixture but still pretty good. N02 takes one cartridge and the first 2 glasses have great consistency, however we have experienced glass 3-5 have much less integrated gas left. That said the difference in price is significant (50c vs. $2.6 for the two N2 cannisters). We are going to try adding another N02 after two glasses to see if that does anything.6. The Drip: There is still a drip issue you need to try to take into account. Everytime I take the drip cover off I seem to spill the drips that are in the container. Hopefully someone knows the trick or there will be a better drip cover in the future.7. There are some pipe cleaners provided to clean the unit. Pretty good so far, but again early days for me with this unit.8. So far I have been able to mix the product and keep it in the fridge for 4 days. Unfortunately current popularity has emptied it within that time frame. I think it will last a week though for sure.Overall, so far I am happy with the purchase of this product and would recommend it to others who enjoy having this product at home and making it for yourself. I think the NO2 creamers will be our standard and for some more special occasions we will use the straight nitrogen. I am looking forward to try to figure out some different uses for the container as well. I think I can use this to accelerate infusion of flavors into my brown liquor. Stay tuned.

After seeing other versions of this elsewhere I decided on the Royal Brew brand due to the Amazon warranty and extensive company and user videos. I couldn't be happier! While some noted difficulty using, I found it worked out of the box in about 5 minutes. I had zero difficulty with any of the seals, foam, etc. noted in the other reviews. just follow the simple instructions included, tighten everything appropriately, and it will make the creamiest, foamiest, nitro coffee you've ever had!A few notes...-One nice addition with the currently shipping model is that includes extra tubing that is now cut to the appropriate 20cm length. THANKS!!!-There is an extra complete seal kit included!! (THANKS AGAIN!!)-Yes it will drip a little after dispensing...totally normal as there is simply foamy coffee left in the dispensing valve that will drip a bit after it condenses. (a small price to pay but I'm going to make a little catch under to get the drips with a fun shot glass or something)-Note that after shaking for 1 minute, the cold brew is nice and foamy. The reason you have to wait for an hour is physics!!!...PV=nRT! If you add cold liquid in a constant volume vessel but increase the pressure (by adding the NO2), the temperature of the solution will increase. This is the only reason you have to wait an an hour. Even if the coffee is really cold going in, it will be room temp after adding the NO2.

The thing got stuck and won’t open after only a few months of use. Customer service unresponsive. I tried everything to release it and nothing has worked. It’s absurd. Such a waste.

Now I'm in the big league with Royal Brew Nitro Cold Brew Coffee Maker Home Keg Kit System (G1 Stainless Steel 64 oz). I used to enjoy alone with the NitroPress but now I can share with my buddies a smooth nitro cold brew of my choice back home. Thanks to Royal Brew for a great product!!!

Only Used twice and has 2 cracks on the barrel, and surface rust. Tried sending an email to their "24/7 lifetime" support via email without success as the email address proved cannot be found.Unable to return or refund because the time line is now out by a few days.Only gave 1 star as I couldn't choose zero star.
