I am bulk aging my WE Lodi II Cab and it has been in my cellar for about a month. My intention is to allow it to age in the carboy for at least 6 to 9 months befor bottling. How often, if ever, should I rack off of the lees while it is bulk aging? And if I do rack would you recommend that I top off with a similar cab? If so what cab would you recommend for topping off?
