... They [Germans] tend to have simple recipes combined with complicated processes. 
Never heard it put that way but that’s spot on!
My recipe was probably more complicated than necessary but it ended up meeting my goals. Not sure I’ll ever get to complicated brew process but I’m not against it by any means
I have tried doing 90m boils, doing decoctions, etc. but I'm generally not going to be doing that on the long term. Somewhere in there I did get some better insight about the way German brewers put their recipes together. They tend to be simple and all the ingredients serve a specific purpose. I've been brewing since 1999 and in those days you might pick up a book and see recipes with 2-row, wheat, aromatic, victory, crystal 40 and crystal 60, pale chocolate, melanoidin, caravienne and scrambled eggs (okay, I made up that part) and one could assume that this is how beer is made. It doesn't have to be complicated to achieve its goal.
