I use BRY-97 fairly often and have always found it to produce clear beers given a reasonable amount of time. If you want anything other than blind speculation as to the cause, you'll need to post the recipe and your process.
Process is exactly the same for all batches done prior. Variables noted below.
BRY-97 (Never used before)
3 week ferment @65 degrees.
20% White Wheat
90 Minute Mash (first time doing 90 minutes)
60 Minute Boil
Centennial-Whole (9.5) (Never used before)
Amarillo-Pellet (7.7) (Never used before)
Simcoe-Pellet (12.7) (Never used before)
60 min = .5 oz Centennial
45 min = .5 oz Centennial
30 min = .5 Amarillo
20 min = .5 Simcoe
Flame-out = .5 each Amarillo, Simcoe
During bottling yesterday a heavy haze was noticed.
"given a reasonable amount of time"
Perhaps after 3 weeks bottle carb/condition it will settle out ?
My current guess, yeast is in suspension, did not pack down well in fermenter.
