Hops?
I've been making beer without hops for years. There's a fair few recipes here: https://www.amazon.co.uk/Sacred-Herbal-Healing-Beers-Fermentation/dp/0937381667 (which is every bit as woo-woo as the title suggests but the recipes are fun). I've also made a really good summer beer (light and refreshing) using Mugwort and lemon for flavouring. Hops were approved of because some of the other ingredients used for flavouring had some interesting* effects on the drinker whereas hops tended to calm them down. Not sure about that last bit mind (even if I have read it from multiple sources), Friday nights in most towns suggest that people will still get rowdy despite the hops.
