Is "悪い所を煮詰めたような" an idiom? If so what does it mean?


I'm reading a passage from a book, here one of the characters is making a few
observations about the personality of another character (慶介 - Keisuke) who has
moved up in status and is a new member amongst the upper echelons of the
aristocracy thereby replacing the old predecessors in the story's universe.

> 先代も貴族の悪い所を煮詰めたような傲慢な男だったが、この慶介という男は表面上は貴族らしからぬ空気も感じさせていた。

I've hit a snag here, I'm not sure how one would parse
"先代も貴族の悪い所を煮詰めたような傲慢な男だった", more specifically "悪い所を煮詰めたような" it seems like an
idiom to me and I'm not sure what it means, I've tried searching on Google and
I got quite a few hits for this phrase, but no explanation about what it
means.

Any help is greatly appreciated!




If no one else is answering..

I myself would **not** call the expression 「悪{わる}い所{ところ}を煮詰{につ}めたような」 an
"idiom" because it simply means what it literally means.

One can certainly 煮詰める intangible objects ('human characteristics', in this
case), not just tangible objects that you can throw into pots.

My own TL attempt:

> "His predecessor (also) was a haughty man with all (sorts of) aristocratic
> vice condensed into him, but this man Keisuke apparently had a non-
> aristocratic air about him."

Without further context, it would be impossible to translate the two 「も's」
very well. The most difficult words in Japanese are single-syllable-long and
are written in hiragana.
