BTW you said your first batch's fermentation got stuck (meaning the fermentation process didn't seem to be continuing or at least continuing at a very slow pace) and there are lots and lots of reasons this could happen. The yeast packet could have been old so that the yeast had died before you put it in, you might have pitched the yeast into the wort while the wort was to hot thus shocking the yeast, some of the sterilizing agent you used to sterilize your equipment might have left a residue which shocked or killed the yeast, you might have over cooked the wort caramelizing the sugar instead of simply breaking the grain starches into simply sugars, etc... There are as many reasons as there are people brewing beer.

Unsticking fermentation can usually be easily done though. Add fresh yeast, maybe a bit of sugar & yeast minerals (which promote yeast growth) and give the whole thing a good gentle mixing (don't aerate the beer though as getting outside gases mixed into the beer can introduce bacteria or fungus; just a good gentle steering) and 90% of the time that will restart fermentation.

Here's some more advise on unsticking fermentation: http://www.homebrewtalk.com/f13/un-s...ntation-55150/
