Great product. Terrible instructions.
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.

Super simple and simply amazing!
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.

Extremely Happy
First, the fit and finish on this is quality. The feel is very solid and seems like it’s going to last for a very long time. I did buy the N2 they suggested and I’m happy I did that. Overall, I am very happy with this keg. I will be trying out the taste soon as I have some nice Colombian coffee cold brewing at the moment. UPDATE: I just received the nitrogen and immediately put 2 cartridges in. The taste is great and everything meets my expectations. I will say, it's not the exact same as you will get from a kegerator setup but it's very close at a great value. I would definitely recommend this to someone who wants a quick and east way to get some nitro brew. Update #2: I was wrong. This is the second time I used it and the nitrogen fitting leaks like a sieve and will not hold. Thank go for Amazon replacement policy. Well see how the next one goes. Update #3: the company contacted me immediately after I sent them an email about the failure. Their customer service is top notch. They offered to replace the valve and completely understood my issue. Amazon already sent me a whole new replacement kit but if that wasnt the case, I would feel confident this company would make it right. Other than this issue, this keg is still high quality.

The best addition to my home barista tools!
I was looking for a nitro brewer to make my home cold brew nitro coffee. This was the perfect size for multiple servings. However, it is recommended that you fill the 64oz. keg 75% full (48 oz). This allows for for the mixture of the nitrogen cartridges. The build and finish of the Royal Brew is phenomenal! This thing is built like a tank with extra hosings and o-rings and a carrier bag!! The spout does drip but there is an included stopper, so this is my only complaint. They recommend using 2 nitrogen cartridges for your 48oz cold brew. After following their instructions on refrigerating and gentle shaking, the head and cascade that this thing produce is beautiful and tasty! Using nitrous oxide cartridges doesn’t taste as good but that is a preference thing, so experiment. Cold brew tastes better with straight nitrogen cartridges. I love being able to take this thing in the road to make my favorite nitro cold brew! It’s easy to take a part and clean with the included brushes. The nitro cartridges are sold separately.

Easy to use with great results - Updated after a few months of use
9/12 - updated review: Unfortunately, the pressure valve has stopped working. When a new cartage is inserted all of the gas escapes through the pressure release valve. It no longer maintains enough pressure to make nitro coffee, or to even dispense flat coffee. Original review: I purchased the 64oz one. I've used it three times so far with nitro only and it has made three batches of great nitro coffee. I just order n2o and am excited to try a few batches with that. The base cold brew recipe they offer is a good starting place. I like my coffee a little stronger and am still working on creating a recipe that I love. Using N and N2O will probably need different recipes for each gas type. Cleaning it is easy. I've used Powered Brewers Wash (PBW) on mine, but I also brew beer and have PBW for cleaning my larger kegs. It works great for cleaning. The smaller keg is also easier to work with while cleaning. So far my only regret is not buying the 128oz keg, but that is 100% on me. It seems like it would be nice to have a few of these kegs anyway, so I'm sure I'll be buying more in the near future.

I highly recommend watching a YouTube video to get the best benefits
Things to know that are important are that this is tall. I wouldn’t recommend measuring your refrigerator before you purchase. I did not but I have a large refrigerator. I only had to move the shelf. It comes with cleaning utensils extra straws, a wrench. This is a very nice product and I have used it twice so far. The first time didn’t go so well, so I watched a few YouTube videos. I would highly recommend you do this. The second batch turned out perfect with all the tips and tricks that I learned. I’m enjoying a nitro cold brew as I am writing this. It’s nice and smooth. Generally, I like cream in my Coffee, but this is so smooth. You don’t need it. I’m very happy with my purchase.

Easy cold brew conversion
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.

Great for coffee and other drinks!
Works great for coffee, lemonade, and other drinks. I love that it comes with all the cleaning and maintenance tools necessary. N2 or N2O both work equally depending on taste!
