Really? You actually need justification? I am enjoying my homemade wine and my only justification is that it is good..
I've been tempted. Raising kids and high stress jobs limited a lot of my "hobbies". Both have almost resolved.
Tell me about the wine. What is your specialty? Easier than beer? I've heard about the same. Better in glass? or plastic works? Future in-law brews and has offered lessons. His is tasty.
