What beer were they drinking in Shawshank Redemption ?

There are few movies which I love to watch again and again. Shawshank Redemption is one of them. A great movie. I was thinking about the beer they used to drink when Andy manage to deal with prison guards. I found it somehow.. this beer brand is called "Stroh". And as I heard it's not in the market currently. The original version.

This scene of the movie is very special. They are enjoying every second of the situation thanks to Andy. Andy was just looking at his friends enjoying the beer in a corner.

Even today we can purchase some new versions : https://strohs-beer.com/pages/beer , it says they follow the same family recipe. But don't know whether it has the same taste of 40's
