Converted fridge in the garage that holds up to six kegs perfectly, plus bottles on the door, yeast in the crisper, hops and empty bottles in the freezer above, and frostly mugs on the freezer door (for those who insist on a frosty mug) No need for more than 4 taps on the fridge door, but I do have a 6-way CO2 splitter so that all kegs in the fridge can be force carbonated via set-n-forget.
2-tap tower on a mini-fridge at my vacation home. Uses a Y splitter on the CO2.
75-qt cooler on wheels with retractable handle, with 2 taps on front and two 2.5gal kegs inside. Can double as a jockey box if I need to transport more than 5 gallons (cold plate on order!)
Also have a 20#, 10#, 5#, and 2.5# CO2 tank, nitro tank, 20oz and 12oz paintball cans, disposable 3-oz paintball cartridge adapter, 16-gram genuine innovations injector, and two picnip taps on 9-ft lines. Total: 16 kegs - with the ability to serve from 10 of them simulaneously if needed. Can serve from a stout faucet, perlick faucet, perlick creamer, traditional faucet, or picnic tap/bottle filler.
I do not ever find myself in a situation where I wish I had more serving capacity or flexibility for lagering, but I’m sure I’ll add something else to my repertoire the next time someone posts something really cool on this forum.
