I like drinks much more than I want to drink alcohol, so generally have on hand home fermented ginger beer and/or tepache or kvass. These are technically not completely non alcoholic but are non intoxicating, like kombucha, and can be mixed for really gorgeous complex adult tasting drinks that leave you clear headed.
Tepache is basically a fruit kvass; you can use the same process with other fruit but pineapple is very robust, tepache is less fussy than most of them.
