My taste for certain beers waxes and wanes. I don't know if it's my pallet or if the receipt for the beers in question has changed. Maybe I drink too much.
As a child, I loved broccoli and cauliflower. As an adult, I still like broccoli, but can't stand the taste of cauliflower. Supposedly, it's supposed to be reversed. The developing pallets of children may not like one/both of these vegetables, whereas their adult pallets can tolerate them. My childhood pallet liked both, my adult pallet can tolerate one, can't eat the other.
