Lord knows what they do today but it's not that long ago that my dad was the lab manager in a brewery, and they didn't do that then.
I know they do it with cider.
They harvest apples, crush them and extract the juice, then evaporate a lot of the water off the juice and store it.
Then they dilute it a bit, ferment it and dilute it again before sale.
That makes sense because apples are seasonal, don't keep well and have a lot of water in them.
However this

still tells you how to calculate the strength of the product based on the "original Gravity" and "present Gravity"
Wine yeast will survive 12 to 15% or so ABV; but beer yeasts typically won't.
(Fermentation stops when the yeast runs out of sugar to eat.)
In some places it really hasn't changed.

Not sure how "small beer" was brewedThe brewing process hasn't changed much.
