Question about filtration

[mirsultankhan]

From what I understand filtration is used mainly by those who keg and force carbonate their beer thus if you are bottle conditioning your beer there seems little point in filtering as you will simply end up with flat beer as all the yeast strains will have been removed by a .5 or 1 micron filter. I was just wondering if there is any benefit to using something like a 25 micron filter which I imagine is large enough to let yeast strains through or is it likely to also let everything else through as well and therefore pretty pointless.

good question!:hat:

Filtering this way will strip your beer of its character, IMO. Time (patience) and low temperature does a better job.

Brew dog filter their beer with a 5 micron filter. I would assume filtration at this pore size may well leave sufficient yeast in the beer to bottle condition. I will perhaps be tempted to try this on my next batch.

Filtration by commercial breweries has more to do with aesthetics and corporate 'responsibility' than the beer itself.

Are the Brew Dog beers bottle conditioned? That would certainly answer the question if they were.

I have heard that Brewdog aren't actually bottle conditioned but that they add in some dead yeast (a really miniscule amount) that gives an aesthetic quality to the beer but they force carbonate like most other breweries. I was on the Greenwich Meantime Brewery tour and they were saying about how if they were to bottle condition all their beers then they would be wasting money.

Good topic- Craig, of Craigtube fame, has a video where he demonstrates this little gadget that takes the sediment out of your beer before you open it. It looks bloody fiddly and is apparently incompatible with glass bottles. Also expensive...I want one.

I did the meantime tour and never heard that. Mind you I'm quite deaf and wuz most likely quite well oiled at that point.:
