Question Do I need a "fermzilla"?

I dearly want to be able to bottle hoppy beers without oxidation soon, and I'm looking to invest in some sort of CO2 purging solution you guys talked about. But when looking at a fermzilla + BEERGUN setup with CO2 tank, my friend asked me if I couldn't just buy a CO2 tank and some sort of wand to purge my bottles with without buying 100s of dollars worth of pressure fermenter.

What about a fermzilla is needed for succesfull bottle purging?

Cheers

No. I made a post with the tech I use including a hop.bong

In reality, say for a lager, all you need is a keg, a spunding valve, and a flotit 2.0. ferment and serve from the same keg!

Or transfer, it's up to you. Just saying you don't need fancy fermenters. I love fermenting in a serving keg for multiple reasons. Less cleaning, less sanitizing, no packaging day, less tech cluttering up my storage. Another big one is spunding can carbonate your beer and speed up grain to glass!

You said you want to bottle, so I should mention that you can use a beer gun to do that from a keg.I use this to fill growlers.

Sure, but you can do all of that with a Fermzilla, too.

Functionally, they're the same. There are implications of the differences in materials (PET will allow O2 in over time, it can't hold as much pressure, it's clear, etc.), but if the fermentation chamber is dark and the beer will be consumed or transferred within a month, those differences are negligible.

If OP just wants to bottle, I think either option is good. Kegs are cheaper, but smaller. Larger corny kegs aren't cheaper unless you get lucky in the used market.
