what about one of these?Any microbes in there are all throughout the beer, so there's no way to avoid or remove them.
Technically, yes, running the beer through a filter 0.45 micron or smaller will remove the microbes.what about one of these?
0.2 micron filter.....
i'm not hearing 'no', lolTechnically, yes, running the beer through a filter 0.45 micron or smaller will remove the microbes.
You would need to buy the filter and filtering apparatus, which is more than double the cost of brewing a new batch, AND the beer would likely need to be fined before running it through such a small filter, otherwise it will quickly clog, AND you need a pump to run the beer through it, but not a centrifugal pump like most brewers use, but rather a diaphragm or peristaltic pump because the residual carbonation in beer would be released inside a centrifugal pump rendering it ineffective.
You would also need to add yeast back in if bottle carbonating.
