My partner and I visited the Castello di Brolio for a sunset tour - the sunset tour has a private option that grants entry into the tower with all the memorabilia, so it was definitely worth it. The sunset tour is given after hours, so you were not competing with other tourists just meandering about during the day.
The castle itself is steeped in history, and our tour in English was quite full. I do not believe there was another tour in a different language, we were the only ones there.
The tour of the tower with historical artifacts from even the beginning of the castle was the most interesting part. We were told that it was not open during regular hours, and they did lock the door before and after us.
The sunset tour also included dinner at the restaurant, and while the restaurant was OK, this is actually a well-regarded winery so it is worth going to the tasting room - you have to pass the tasting room on the drive up to the castle.
