Nitro Cold Brew Coffee Maker Home Keg Kit System by Royal Brew

Water2wine: I set this up immediately after I got it delivered. I had a cold brew already made to use. Because I wanted something to drink instead of an alcoholic drink (transition from work to fight ritual), I went with a dark roast decaf expresso bean and added a vanilla bean pod to the cold brew, and viola! The nitrobrew came out as I had hoped. I used two nitrogen capsules and will try nitrous oxide next.

Christine: We love the whole system but having some difficulty maintaining the foam. It seems to last for 1 serving and then peters out. We first used a nitro cartridge but not much foam then bought the nitro oxide and it was much better but just lasts for one glass. Any suggestions? Are you supposed to add a new cartridge every day that you tap a cup?? Love the smoothness of the coffee, even after a couple days, it's still super smooth. Thanks for your help!

Carmen: Nice for small batches. Wish it came with better instructions. Also, it’s not quite a kit, just the keg! You’ll need to purchase N/NO2 canisters and have/make cold brew (a sample concentrate or cold brew recipe would have moved this to five stars).
I’m still getting the hang of brewing cold brew but the consistency of pours has been wonderful!

Trev: Used this a few times the first week I got it. The first time it worked well, but I noticed after that I didn't seem to get the same nitro each time. And yes I did replaced the cartridge after each use, actually I needed to repalce after each cup. Perhaps I used it wrong so I'll add a star, but it wasn't as great as I had hoped it would be.

Timothy Mok: The keg is top heavy so it starts to become unbalanced as you near the bottom. The last couple of pours also don't have as much gas. It's not really a cold brew maker either as it's only for dispensing. Over all quality is fairly good and it keeps pressure. The spout drips easily so there's a spout cover included. However, it collects the coffee which kind of splashes all over when you try to take the cover off. That said, putting the cover on requires a bit of wiggling to ensure it's snug. Condensation builds up on the tap quickly so you really have to jam the cover on so it stays. Then taking it off means you have to be gentle or you splash cold brew around that it had caught from the previous pour.

It's a novel way to have coffee at home and pretty cheap aside from the initial cost. It would be nice if it had some adapters for CO2 so you could have sparkling water or beer. It seems that there are no CO2 cartridges that are the same style as the N2 and nitrous ones. It's a single use device that requires quite a bit of fridge room (64oz version).

Arkyspe: Made my first batch yesterday. And I have to say, it was pretty darn good.

As for the build, the craftmanship/quality on the machined parts was excellent. It was pretty easy to assemble. It took me no time to assemble and only 5 minutes to fill and charge the tank. Working on my second batch today.

KaeliKaeli: Let me start off by saying I am a nitro fanatic - coffee, matcha, golden brew, stout - I love it all. The creamy mouthfeel of a nitrogen infused beverage is second to none. With this, I found a large sum of my paycheck going to Starbucks' nitro coffee. I am not a fan of Starbucks (even though I am a Seattle native) and so it pained me to continue to feed them money. I began researching at-home nitrogen taps and this one came up. One a whim, I purchased the 64 oz. and it arrived at my house promptly two days later.

I immediately made a batch of cold brew and was impressed by the cascading foam. However, I noticed that the foam dissipated rather quickly. I contacted Royal Brew's customer support and they quickly replied and informed me that I had neglected to add an o-ring to the connection between the spear part. I went back and added this and it seemed to help quite a bit. I continued experimenting and found that adding any source of dairy - whether goat milk, cow milk, half-and-half, or pure cream significantly increased the foam stability (foam is a suspension of air in liquid).

The N2O cartridges add a sweet almost metallic taste to the brew which can be both...
