Nitro cold brew coffee is almost too easy with this tool. You want smooth, creamy, frothy, sweeter (as in really is black, no actual sweetener needed, but via the placebo effect in texture, it tastes sweeter) coffee? First take your favorite cold brew, preferably made yourself by grinding your own beans then doing at least 12 hours in filtered water (all those things make a huge diff). Just pour up into this tank, I fill it all the way to the top and it works fine, no explosions, about 20oz, then use your n20 tanks, you can do isi brand for example, as long as they’re 8g size n20s, and dispense for the most luxurious black coffee you can have. It tastes even better than Starbucks nitro imho, because you can use your own bean preferences. I use a medium Chiapas bean with dark chocolate, creamy and rich tasting notes. So in the end my black coffee is essentially like a cold-hot chocolate (like the kind at Christmas) even though it’s not sweetened, flavored or with any additives other than nitrogen. If you do the math, you’re looking at 50cents per cup of brew, including the price of beans, if you get your n20 tanks (charger) on amazon, like the 50 pack for 30$. Then each n20 tank will do 20oz(my overfilled canister ;) ), so really 2.5 cups per n20 tanks used, that’s about 50cents per cup bc my beans are 11$/lb and I do 4 oz grinds per gallon(128oz) for cold brew. How much for a grande nitro at Starbucks? 5$?! So if you drink this everyday as I do, 15$ a month vs 180$/month at Starbucks, ouch, not sustainable!! But this method is! And this is premium, best of the best, hipster stuff. You can’t get a better, imho cup of joe than this. And it’s important to do a 1L (this) size vs a 8oz mini(1/2 pint), bc each 8g n20 cartridge/tank/charger will do 20oz with a bit leftover, but if you do the 8oz one, you waste tons of n20 and money! I started with the 1/2pint whipper and upgraded. Honestly I could probably do a 1.5L whipped cream canister and it’ll for sure use the whole n20 with no leftover wasted gas. speaking from experience and tons of experiments guys, this is a winner here! You can do xantham gum powder(1/2g) with your brew and blend it like crazy, which works well too, but n20 infusion tastes better, but you’ll want the best. xan is close too, and far cheaper! Also I have the uKeg nitro growler that specially makes nearly 2 liters (64oz) of nitro cold brew that includes a tap (which supposedly helps make it frothier and cascade more thus tastier) but this whipper is far superior at cascading and making it creamier thus tastes best.Update 6-11-20: eventually the trigger handle bent after overfilling coffee tons of times which means it was hard to squeeze bc of the force required after n20 discharged inside, so I‘m using a diff lid/nozzle from another model but the eurkitchen canister is the best bc it’s more insulated even tho it’s just the aluminum one, but compared to the other dispenser, it’s much heavier and thus maintains colder temps out of fridge longer. Now that I see there’s a stainless model available I’ve got to get that to withstand my overfilling! Which makes the creamiest nitro. Fill to top, dispense n2O charger without shaking which somehow creates this cascading effect best bc the bubbles are tinier/more fine, so still the best nitro coffee you can DIY, don’t waste money on a growler!
