I have always racked onto a crushed campden tablet when racking to another DJ to degas and clear as that was what they all did back in the day when i started (2013) i have read that its not necessary if you are not going to age the wine for a very long period, as you say you drink it when its a couple of months old so i don't think its necessary.
Campden tablets have multiple uses in homebrewing and are a versatile tool in both winemaking and beer making. Campden tablets are one of 2 chemicals, either sodium or potassium metabisulfite which have unique attributes useful to the brewer.
Firstly they are used to sanitise wine musts and juices as well as equipment but can also be used during racking as both a measure to prevent bacteria from spoiling the wine and also as an antioxidant to keep air from staling the wine.
