Exact difference between demi glace and bordelaise?

Exact difference between demi glace and bordelaise? - Handshake Between Two People

This feels like a stupid question, but I've spend a fair bit of time reading about this without finding an answer... I'm trying to understand the French mother sauces and their derived sauces. I am confused about the differences between demi glace and bordelaise, their place in the 'system', and whether roux is used in either.

Reading about espagnole here, I learn that espagnole

  • Starts with a brown roux, and
  • Can be used to make demi glace AND bordelaise.

This confuses me, because I've encountered recipes for either, which have not mentioned roux. For example, this demi glace recipe by ChefSteps makes no mention of flour or roux - only reduced wine and stock.

Similarly, this bordelaise recipe, for instance, is virtually identical (except for adding butter towards the end).

Hence, I'd be grateful if anyone could help me understand

  1. Precisely what is the difference between demi glace and bordelaise?
