You need some micronutrients for the yeast to eat or they'll get stressed out and make sulfur farts.

My recipe for a 5gal batch is:
>3 3qt bottles of Great Value apple juice (9qt)
>2 gallons spring water
>10lb white sugar
>1 packet champagne yeast

Then I make a yeast nutrient blend that I add twice. Once in the beginning after aeration, and again 3 days later.
Boil together:
>1/2 cup grape nuts
>Juice of 2 lemons
>2 liptons tea bags
>1/2 of a vit B complex pill
>1 packet active dry baking yeast
>2 cups water

This mixture ferments vigorously if well aerated and at the right temperature (not above 75°F), finishes ferment in 8-10 days at 16% ABV, clears up after racking into gallon bottles and sitting overnight in the fridge. Tastes like white wine with added vodka, no farty smells or anything. The whole batch costs about $20 and gets you the equivalent of 25 750ml bottles of wine, less than a dollar each.
