I've got the WE Diablo Rojo kit and they say it's ready to drink at 4 weeks. I'm entering the final stages. I'm adding the last of the packets it came with soon and here's my question. With these cheaper kits will I add a noticeable improvement by racking the wine and letting it bulk age in the carboy? How long should I let it age and should I cover the carboy to protect it from light?
