In my quest to be healthier, I've been eating a lot of probiotics, mostly in kefir, but I've found Kombucha again and have added that to my daily regiment.  But now that my one bottle is finished, I've decided to try and make my own. 
Regular tea
1 cup sugar
4-6 bags tea -  for loose leaf, 1 bag of tea = 1 tsp
Kombucha Starter Culture – SCOBY
1 cup starter liquid
purified/bottled water
tea kettle
brewing vessel
cloth cover
rubber band

Boil 4 cups of water.
Add hot water & tea bags to pot or brewing vessel.
Steep 5-7 minutes, then remove tea bags.
Add sugar and stir to dissolve.
Fill vessel most of the way with purified water, leaving just 1-2 inches from the top for breathing room with purified cold water.
Add SCOBY and starter liquid.
Cover with cloth cover and secure with the rubber band.
Say a prayer, send good vibes, commune with your culture (optional but recommended).
Set in a warm location out of direct sunlight (unless vessel is opaque).
Do not disturb for 7 days.

After 7 days, or when you are ready to taste your KT, gently insert a straw beneath the SCOBY and take a sip.  If too tart, then reduce your brewing cycle next time.  If too sweet, allow to brew for a few more days.  Continue to taste every day or so until you reach your optimum flavor preference. Your own Kombucha Tea Recipe may vary.
Decant & flavor (optional).
Drink as desired! Start off with 4-8oz on an empty stomach in the morning, then with meals to help with digestion or as your body tells you it would like some more! Drink plenty of water as it is a natural detoxifyer and you want to flush the newly released toxins out.

Here are a few recipes I've found to make, I'll let you know how it goes.

Plain tea
6 cups of tea
2 cups unflavored kombucha
⅓ cup sugar
Fresh Squeezed Orange Juice
Mix 1/2 and 1/2 of Kombucha with OJ.
Add vodka to make it a cocktail.

Ice cream float
2 scoops of your favorite ice cream, sherbet, or frozen yogurt
12-16oz of flavored or unflavored kombucha tea
This will get foamy, so pour slowly.

Stay thirsty my friend!
