Add Irish Moss or Whirlfloc near the end of the boil, and ferment with a yeast known to be a high or rapid flocculator. Generally the yeasts technical data sheet will list it as a high, moderate, or low flocculator.

Cooling once fermentation is over helps too, as does transferring to a secondary fermenter before bottling/kegging. You could use a fining agent post fermentation but I find the other methods already mentioned effective, and free.

Finings adjunct and isinglass. Clears most beers in 24-48 hours if it's the yeast causing the lack of clarity.

Getting mash pH into the right range. Using enough Calcium. Requires you to ignore US advice.

Yes, the best way would be to avoid clarity problems to begin with through good brewing practice. Subsequently a little time in cool storage (perhaps with finings if greater speed is needed) will normally clear it OK.

Probably the fastest way would be to filter the beer with very fine filters; this gives almost instant results. Though it is neither the best nor the easiest way for many homebrew situations IMO.

(Or you could just leave it cloudy and try to pretend that is acceptable for craft beer :twisted: )

Remember that clarity isn't the only factor though - many beers benefit from at least a little maturing. If it is prematurely fined or chilled heavily, let alone filtered into lifelessness, then this will delay or prevent the yeast doing their post-fermentation good works.

Don’t how I forgot this - yes - since I started treating my water, beer clarity has become much less of an issue. Water is very soft where I am.

It's alkalinity that's the enemy as it acts as a buffer, resisting the shift towards acidity that grains and calcium can give you. Pale malts much less, Crystal and dark grains more. Your soft water should be less of a problem but like a lot of things it is a question of how soft or how hard, or more precisely how alkaline.

hi all, so i normal put half a pro floc tablet in, last 15 minutes, of boil.
23 ltr batch,
i then ferment in the primary for week or so,
then transfer to secondary for a week,
then transfer to corny keg , chill down to 4 degrees , then force carb at 30 psi,
then let t settle to around 12 degrees,
and star drinking,
does this seem about right.
thanks.

It seems generally reasonable to me. Though personally if I were going to the effort of transferring to a secondary FV then I would leave it in there longer than a week if needed, or else chill and/or fine in there, such that the beer is quite clear and the majority of sediment generated would be left behind before kegging. For just sitting in there a week, it might almost as well be left in the primary fermenter (unless e.g. it doesn't seal well enough for an airlock, or you need to vacate it for the next batch).

Over and above that regime, brewing is partly a gradual process of preventing or removing stuff you don't want right from the start. So for optimum results take every opportunity to do so, and there will be less to cope with at the end.

This could include using decent grain (e.g. not too high in nitrogen), getting the mash pH right, having enough calcium in the water, keeping unnecessary grain particles out of the brew kettle, not sparging excessively (or badly), having a suitably turbulent/rolling boil, using kettle finings (as you mention), keeping unnecessary hot break and hop debris out of the fermenter, using decent healthy yeast and treating them well - all before the post-fermentation clearing stages.

Of course, this isn't something that happens overnight; even after all these years I'm still refining and improving things.
