I'm not sure why one would would think that there is a potential problem if their meads do not clear within a few months ..... Depending on the yeast strain I'm using, I will go a minimum of 2 months before racking for the first time, and in the case of some of my meads where I use a strain that is known for imparting favorable lees aging characteristics (D47 for example), I will go 6 months to a year before racking for the first time.
One needs patience if they are going to be a sucessful mead-maker. All of the traditional (by traditional I mean not a 'quick-mead' like JAO) meads I make are bulk-aged a minimum of 2 YEARS before I bottle - if, that is, I actually decide it's ready to bottle at that point .....
