Lately I have noticed how many commercial beers are not crystal clear...maybe it is due in small part to the Haze Craze, but I think tolerances for a little haze have increased.
I wish I knew what the magical clarity results were, so I could implement them, but frankly, I get some beers that just take a long while to clear and some just don't. I use Brewtan B and Whirlfloc and I space out their additions by at least a few minutes toward the last 16 minutes in the boil, because it was mentioned as a best practice, but perhaps I have rushed them too close together on some occasions? Who knows?
The clear ones do have more curb appeal, but I made a Landlord clone recently with Simpson's Golden Promise and it just has a touch of haze that doesn't seem to want to go away. Malt issue, perhaps? I had some issues with North Star Pils under pressure fermentation, so maybe it is due in part to that....a real tail chaser inquiry, for sure.
