Verona is about an hour west of Venice by train. I plan to spend two nights there is September after leaving Venice. I think they are known for white wines in the region. The town of Soave (wine by same name) is about 25 minutes east away from Verona by car. I have never been there but understand that it is lovely. Some friends tell me that town of Soave is worth a visit. The town of Monteforte d'Alpone, also east of Verona, hosts a raucous wine festival in September. BTW, the web site
www.rome2rio.com is an excellent tool (downloadable app, too) for travel options. I have also found
http://www.italiarail.com to be more user friendly in searching for train fares and schedules.
