Watering Aloe Vera in Winter

The best way to kill your Aloe Vera plants is to over water them. You are advised that the soil should dry out between waterings and in Winter to hardly water at all. But how do you estimate hardly water at all, my recent policy has been to give my plants a soaking every two months in the Winter. On a nice afternoon take them outside and fill their pots to the brim with preferentially rain water, perhaps with some cactus feed mixed in.
