Fucking snobs. Carry on, cujo. Drink that homemade plonk with pride. No need to pour that sulfite laden store bought stuff down your neck.
And another thing - wine only from grapes? Fucking reductionists. You could bloody well make a jalapeņo wine if you were so inclined. Why, I had a gorgeous few glasses of wine made from hibiscus and roses just last week.
