You just buy an extra keg. Always have a batch fermenting. Transfer beer to keg when you’re 4 points from predicted FG (tilt hydrometer makes this easy) and using a spunding valve to set pressure to 30-40 psi (depending on room temp and targeted vol co2). Once a keg in your keezer kicks, the keg will be carbonated and ready to drink in 12-24 hrs once it chills.
I use a ball and keg temp controller to control fermentation temp because it’s the most cost efficient way of controlling fermentation temp currently. Takes up way less space than a fermentation fridge or keezer.
This combined with an anvil bucket fermenter allows for closed gravity transfers to keg. I keep hops for dry hopping suspending on roof of fermenter with magnets. Never have to open unless I’m adding fruit or more than 2 sets of dry hops.
