As you've probably already guessed, we're back with good old TGL 7764. The 1960 version.
I am planning to do a compare and contrast with the 1980 version. Which will be fun, as the beer styles changed quite a bit.
Now, you might be rather shocked by just how short the shelf life was of most types of beer. For the weakest, not much more than a week. Even a beer as strong as Porter was good for less than a month.
This might seem far too short a time to be practical. But, most beer was sold quite close to the brewery. And stuff like beer didn't hang around in the shops very long. I can remember well the instability of Eisenach Hell. You wouldn't want to hang around too much on your way back from the shop in case it had gone off by the time you got home.
Why were they so unstable? Because they weren't pasteurised and only rough filtered. Leave a bottle a couple of weeks and it would start to throw a sediment.
Two exceptions were Doppel-Caramel and Malznährbier. Because of the large quantity of unfermented sugars in these types, leaving them unpasteurised would have been extremely dangerous, likely leading to bottle bombs.
Way out in front in terms of longevity was Berliner Weisse. For the simple reason that it was bottle-conditioned.
