For beer I recommend only using the 50 and 20 micron filter cartridges. You really don’t need much more than that, although I have used 10 and 5 micron filters with clearer brews, such as pale ales, etc.
My best results with beer to date have come from using the 50 micron filter cartridge to filter the beer after primary fermentation, typically while transferring it to the next fermentation vessel. Then I filter it again after secondary using the 20 or 10 micron filter, which is typically just before adding the priming sugar and bottling the beer.
For wine I use the 5 micron filter cartridge after the first clarifying, which is 3 to 4 weeks after I added the clarifiers and stabilized it with a small dose of potassium metabisulfite.
My best batches of wine have been the result of following this schedule:
- Primary fermentation – day 1
- 3 to 4 weeks later – rack to a carboy, the clear it (stir out the gasses, add clarifying agents, etc.)
- 4 weeks later – use the KLR Filter with a 5 micron filter cartridge and transfer the wine to another carboy.
- 4 weeks later use the 1 micron filter cartridge when you transfer the wine to another carboy
My wines are really excellent after about 4 or 5 months. Many wine kits say they are done in 6 weeks, but the results will be disappointing. Take your time with wine and let it age. You’ll be much happier with the results (as will your friends).
