Root Beer Report

I tried the root beer today--two days later, and it was pretty good, although it smelled a little yeasty. I read on a site that if I use brewers' or champagne yeast, that could remedy this problem. Anyone know where to find brewers' yeast in Korea?

As far as alcohol content, I suspect there is a little, but Fankhauser's site (see below) assures me that the alcohol level is minimal.

The carbonation was nice, although it could use a little more, in my opinion. According to the directions, leaving it in the fridge for a few days will help, so I'll do that with the other bottle.
