Well, I'm not very experienced at it yet myself, but always enjoy sharing ideas. What kind of wine are you making?
The other night I opened a bottle of my latest batch of apple wine. It was actually supposed to be hard cider, but I was too busy at work when it was time to bottle it, so the yeast was dead by the time I added a little sugar for the secondary ferment in the bottle. However, even though it's not what I was trying to make, it turned out great in the end.
Rather than being dry, extra tart, and supercharged with carbonation, it is semi sweet and just a little spritzy. But by far the best part is the aromas. This year, it was rather cold out in my garage the entire time it was brewing, even freezing many times. This slowed down the ferment and preserved the aromas much better than in warmer years past. Past batches smelled like yeast, beer, and a bit of applesauce, but this one is bursting with fruit, spice, and floral aromas. (also yeast since it's so young, but bottle age should help) I don't even know where they came from. I haven't gotten to do a formal evaluation on it yet, but am really pleased so far compared to my previous efforts. I think this will convince me to control the temperature of fermentation more closely in the future.
