i basically have this (it's a clone of a clone, i mean it's just stainless steel and o rings)Hell yeah.
Nitro Cold Brew Coffee Maker - Home Brew Coffee Keg, Nitrogen Coffee Machine Dispenser System w/ Pressure Relieving Valve Kit & Stout Creamer Faucet - NutriChef NCNTROCB10
from what i researched b4 there are 3 ways to get cold brew
1. whipped cream dispenser w/ catridge
2. mini keg w/cartridge
3. keg o rator with mini fridge and n2 from a supply store
you can easily tell that the whipped cream dispenser isn't gonna cut it, the mini keg is now what most ppl use (i guess as there are so many clones now, when i got mine, mine was the only one)
i use 2 cups of cold brew to 4 cups of water and that fills it up.
then i puncture in a cold n2 cartridge shake a little and out it comes, after the first pour i do another n2 cartridge, it'll take two n2 cartridges to pout it all out, i don't do 2 at one b/c thats too much pressure, b/c you can tell the instance you do that the pressure relief valve lets out all the gas (which is good, you don't want explody)
to keep it economical i buy n2o cartirdges in bulk
comes out to 45c per and you use 2 per
of course you can buy co2 for like 10c but then it's not nitro cold brew is it? it's just gassy coffee, you use the n2o cartridges for that "sweet" foamy taste.
