A defin­i­tive, com­pelling, and humor­ous tale of the fizzy drink that has cap­ti­vat­ed gen­er­a­tions. Seltzer is more pop­u­lar now than at any time in his­to­ry. To many Jew­ish Amer­i­cans it is an essen­tial mark­er of their cul­tur­al her­itage. Seltzer­topia tells the sto­ry of mod­ern seltzer mavens, wran­gling cen­turies-old machines to fill siphons with sparkling water, keep­ing alive a pas­sion that often defies log­ic. Seltzer­topia uses their sto­ries as a lens through which to con­sid­er the social, cul­tur­al, health, envi­ron­men­tal, and eco­nom­ic impacts of seltzer on a world with a seem­ing­ly bot­tom­less appetite for the drink.
