Most people start with Skeeter Pee and modify from there
http://skeeterpee.com/?page_id=17Basically you’re going to ferment a mixture of lemon juice, water, and table sugar. When it’s done fermenting, you add Sparkalloid (a fining) to clear it up. You’ll also add Potassium Sorbate + Potassium metabisulfite. These are stabilizers that basically kill the yeast. Then it gets sweetened to taste. Since the yeast are dead they won’t eat this new sugar.
It’s around 10% alcohol. I usually put it in wine bottles but beer bottles work fine too. Don’t expect to carbonate with sugar though. You’d need kegs for that. Most people like it just fine as an uncarbed drink. It tastes somewhat like a white wine. I serve it in wine glasses.
If you don’t have a “slurry” of yeast you can make a starter. Check the FAQ page for more tips. Don’t bother with a 1 gallon test batch. The ingredients are cheap and everyone loves it. It’s ready to drink in about 2 or 3 months. Mine is still good at 2 years and counting.
