Hey y'all,
Is there any reason a darker beer would be more difficult to filter than a pale beer? We're having some serious difficulty filtering our Schwarzbier with our DE leaf filter, and we're at a loss in determining the cause.
We're primarily a lager brewery, and we filter just about everything, except the occasional ale (which we clear with finings). We use the same lager strain for all of our other lagers (German bock lager), and all of our lagers are 100% malt beers. Our other lagers filter fairly easily after 10-14 days of lagering. But the Schwarzbier blinds the filter almost immediately unless we give it more like 14-17 days of lagering time. Maybe we're just not lagering long enough, but like I said, we're not having any issues with our other lagers with our current lagering schedule.
We filter with Perlite 23S or 27M, depending on the level of clarity. For the Schwarzbier, we use Perlite 23S. Our batch size is usually 60bbls and we have a 3m^2 Velo DE filter. Anyone have any suggestions or insights? I'd be happy to provide additional information regarding our fermentation or filtering process if it's helpful.
Cheers,
Matt
