One thing for sure, Thunderbird the wine is bad stuff.
I worked with an old black man back at my first job. He drank Thunderbird after payday and whenever he had any money. When he was almost out of money he drank what he called green lizard. It was the stuff barbers used on customers that asked for a shave. It was mostly alcohol with a stinky scent. It was super cheap since it had no booze taxes. He said it tasted terrible but it got him drunk.
