A single shot depends on where you are. In most parts of the US, a shot is 30-35ml or 1-1.5 fluid ounces. In the UK, a single shot varies between 25-35ml. That means 100 shots of beer (or any alcohol for that matter) is between 2,500ml and 3,500ml total. Or 2.5-3.5 Liters. If you want ounces, 100 shots of beer is 84.5-118.3 fl oz. When you take into consideration that the standard serving of beer is 12 ounces (0.35 L), that means 100 shots of beer is 10-12.5 regular bottles of beer, depending on the shot size. That might not seem like a lot, but 100 minutes is a short amount of time to guzzle a 12 pack of beer!
