I brewed a porter three weeks ago, let it sit in the primary fermenter for about a week, then racked over to a glass carboy on top of three vanilla beans. It's been sitting in the carboy for 2 weeks now, at room temperature (~65F), and I'm getting ready to bottle. My batch before this was an amber ale and I followed the same basic process (without the vanilla) and after three weeks it still has not carbonated much. Any ideas for making sure that my porter carbonates the way I want in time for Christmas? I want to open the first bottle Christmas Eve (in 4 weeks) and have it be perfect...
