You’re right… their labeling is a little confusing though. I’ve never even seen a 120 minute although I hadn’t been looking for them. They wouldn’t have lasted two weeks in my fridge. Looks like one would do it unless you’re drinking all day long or just trying to get hammered. Great now I’m going to go find this. Maybe a little heavy for all day on the boat though. This looks like a good one for movie night.
