It depends what you like, tailor it to spices you enjoy. I like some carroway and juniper berries in a german style one.

I also really like ginger, garlic, and chillies for something a little kimchi inspired, (kimchi technique is rather different, but I just adapt the flavors to kraut).

Timbre has a very specific meaning, neither mood nor vibe. It is the sound quality, like a flute sound vs a sax sound.

Fun fact: it’s pronounced ‘tamber’.
