Don't know but I am currently drinking a Hoegarden clone that I put in bottle on 10/28 and it is crystal clear. Also, I did it with a bunch of LME so it is much darker - pretty much red or amber - than a wit should be. Looks lovely, tastes absolutely delicious, but does not look like any Hoegarden I ever had.
If you want to reintroduce some cloudiness roll the bottle a bit immediately before serving. Or follow Hoegardens instructions: pour half the beer, gently swirl the rest of the beer in the bottle to loosen the sediment, and then pour the entire contents into the glass.
