i had to google because i read it as "trub" not "troob", and some people are putting an umlaut on the u. not judging, but i thought i was anglicizing it when saying it, but apparently it is "trub".
um i think i just also came up with a kind of discovery here. lol, you often (not always
) hear brewers saying "ver-t/vert" for wort. ha apparently this is an english origin word.
it should likely be pronounced "wort". in german it is "bierwürze" that is defined as "liquid, created during the mashing process"
the process going on here is hyperforeignism, likely due to the belief in the strong (and so it is, at least since the mid 19th century) connection between brewing and germany. not to get too far into it, but anton dreher and others in SW germany went to England and Scotland to see the world's most impressive industrial brewing methodology and took that back with them.
lol, so maybe this is not news to some, but i know i frequently hear "vert" and have heard people say "troob" rather than "trub"
