Honey and mead
Mead is the drink of ancient warriors marching off to battle. They dine in halls flowing in it and enjoy mead as if there’s no tomorrow. Only wine has made it obsolete. Regarded as Ambrosia or the Nectar of the Gods in ancient times, mead can be made sweet with honey.
You will need water, yeast, and lots of honey. This again entitles you to a creativity spree which you can enjoy. As honey mixes all too well with other ingredients, the sky is actually never the limit. You can make one as easily as you make recipes for eggs.
