Like Herbal Tea, most drinks you see in cups can only be brewed on a Stove and also require Purified Water as an ingredient - so you would have to put the same effort into making them as you would get this tea, or find them through looting points of interest. Optionally, you can simply go with berry pulps or rely on waterskins if you are just looking to hydrate yourself and skip Herbal Tea. Regarding stamina regeneration, I have previously mentioned that consumables will not regenerate stamina the same way as Herbal Tea does for speed and effectiveness, but it's possible to find other acceptable alternatives to stick to if you want to avoid this tea. Blackcove Rum seems to do the job to quickly restore your stamina, even with slightly dangerous side effects, but it can not be crafted, only obtained from looting especially Black Hand enemy's corpses for example, which makes it a more rare item to find. Some other drinks or foods may not provide an effective and fast stamina regeneration or might be possibly as expensive as Herbal Tea. Increasing your stamina points through other ways I have also mentioned in this guide can be helpful due to the limited consumable choices.
