Good morning, first of all I apologize for the late response. I was away from HIVE for a few days, due to personal issues.
Let's talk about the details you mentioned: I tried about 10 types of beer at the time, but I didn't try more because you can't appreciate the detail of each flavor and the bathroom was cramped, very peoples. I drank almost 2 liters in different beers, I only bought 200 ml glasses.
Man, the place to enjoy it is excellent, but I found the number of people worrying. I don't like crowds. I like something more peaceful. Regarding the beer barrels around the place, I didn't try any. Honestly, I was afraid to drink them because I didn't know where they came from, but there was a long line for each barrel.
It was a great day. I didn't know about the event. They said it's held annually in September.
