Can we dispel the myth of the 'CO2 Blanket' ?

No you don't smell the CO2, but in contact with the moisture in your sinuses and airways, CO2 forms carbonic acid which will cause a burning sensation if you breath in air with high concentrations of CO2.

Brew on

i effing love that burn.

Yup. Sort of like the Streisand effect. The more someone posts to change something, the more attention it draws.

Idk which will do more to dispel the myth, Doug’s link to an actual demonstration of science showing the relevant principles at work, or OP’s reminder that this is basically fluid dynamics, which makes it pretty easy to imagine standing in a swimming pool 4 feet away from a 10 year old kid who faces you and makes the I’m peeing right now face. Would any of us really believe that the increased density of the cool water surrounding you would create a “protective blanket” in that situation?

Whatever people are smelling in chest freezers or fermenters isn't CO2, which is odourless. I'm not suggesting there isn't CO2 in there as well.

Being odorless does not mean it will not burn your nostrils.

CO2 is a colorless, odorless gas produced during beer fermentation and also used in dispensing systems. CO2 displaces oxygen in enclosed areas and when it accumulates it can lead to dizziness, loss of consciousness, and death. Although CO2 causes a burning, acrid sensation in the nasal passages, this symptom should not be used as a means of detecting the gas. You should only rely on a calibrated gas monitor.

I'm working on a fermenter with about 0.000003 solar masses. The CO2 blanket will work great. I'm still working of thermal regulation, and buying enough grain will be difficult.

UGG me always thought convection mixing due to heat transfer. Like pouring cold cream into hot coffee, ugggg, stirs itself.

me thinks mixing of air in cold freezer or cold fermenter by opening more mechanical, not so much by temp? seems more mechanical from lifting of lid and changing pressure.

but i’d guess the stirring comes more from creating low and high pressure than temperature when movin the lid on the fermenter


beer logic
