Pressure rated fermenters, and capping the fermenter just as fermentation is ending, with an appropriate PRV/Spunding valve, is just too easy. And there are plenty of fairly cheap options. Great thoughts!
Process is the causation of this problem. Naturally conditioned processing avoids this problem entirely. Lagers or ales. Cold crashing a naturally conditioned ale or lager in a bottle or keg happens after the introduction of C02 to finished pressure. Adding either actively fermenting wort at high krausen or plain un-yeasted wort most often from the same batch or an identical batch, which creates carbonation naturally, without the need to introduce any bottled gas will offset any temperature compelled volume reduction and consequential vacuum or negative pressure. The tricky thing can be to calculate the amount of krausen or gyle required to generate the desired volumes of C02 for the finished product. The Krausen/Gyle Calculator on Brewer's Friend has never failed me. Never a bottle bomb, only 1 infection in 1 bottle over the years. Cheers Steven.
Why couldn't you just drape a balloon over the neck of the carboy, and allow the suckback to occur? The rubber membrane would get sucked into the vessel (ie: the balloon would partially inflate inside), but as long as there's a barrier between the beer and the air what would it matter? Just wondering.
Balloons can contaminate your brew. Some people do use a milar and fill it with c02 to balance the pressure. Best practice is to just cold crash on a keg if you can. It's only for clarity so it's not a deal breaker.
@@NWsmallbatchBrewing OK. Sorry then. I was just sayin' that I don't think the balloon would necessarily touch the beer inside, and would still be sanitized beforehand. I'm gonna give it a try, maybe tonight, on a carboy of water, just to see what happens. Not an exact comparison perhaps, but water still shrinks quite a bit when cooled. I'll let you know what I find out.

Why do I keep thinking there should be a red Swingline stapler in this video?

That's expert mode brewing right there :-)
@@NWsmallbatchBrewing I am no expert. Larry taught me everything I know with exception to the natural carbonating process.

@@theghostofsw6276 if you can get a mylar ballon.. the foil ones....that seems to hold up better to the cold
