Brew #10: Root Beer

I did two 2L bottles, a day apart from each other:

7/24: Batch 1 -

1/2 tablespoon of Rainbow root beer extract
1 cup priming sugar (had table sugar but didn't see it until later)
1/4 tsp Red Star Pasteur Champagne yeast
Filled the rest of a 2L bottle with tap water (sanitized bottle)
Gave it good shaking
OG 6.8 Brix
7/27: Put in fridge
7/29: Drank it.  Not enough sweetness, but carbonation is awesome.

7/25: Batch 2 -
1/2 tablespoon of Rainbow root beer extract
1 cup table sugar
1/4 tsp Red Star Pasteur Champagne yeast
Filled the rest of a 2L bottle with tap water (sanitized bottle)
Gave it good shaking
Didn't check gravity
7/28: Fridge
7/30: Brought to family gathering and it was perfect.
