"A century ago, before it was called sparkling water or club soda, and before it was sold as LaCroix and Spindrift, it was called seltzer. No plastic bottles or aluminum cans magically appeared on grocery shelves. Instead, factories across New York City pumped fizzy water into heavy siphon bottles that were distributed by deliverymen.
Nearly all those seltzer men are gone now; one seltzer works remains...
Kenny Gomberg, who built most of the factory himself, works as the handyman (being the only one who knows how to repair the old machines).
...The seltzer-making area is a Willy Wonka series of units connected by pipes. The star of the show — and the company’s workhorse — is a squat, century-old carbonator that blasts bubbles into triple-filtered tap water at a 43-degree chill. Its 65 pounds per square inch of pressure — too strong for plastic bottles, hence the use of handblown glass bottles made in Europe — breathes bite into an egg cream.
“Good seltzer should hurt — it should be carbonated enough that it kind of stings the back of your throat,” said Mr. Gomberg, who earned a master’s degree in higher education before opting to revive his family’s abandoned delivery service a decade ago. Now his crew has roughly 600 customers (a 10-bottle case costs $50, including delivery)...
...On a recent afternoon, Walter Backerman, 70, was filling his bottles when a ratty old van backed in. His father, Abraham (Big Al) Backerman, was buried with a seltzer bottle. The younger Mr. Backerman, one of the last of the old-school seltzer men, hobbles from years of lugging cases up and down stairs. His carrying shoulder is shot. Each case weighs more than 60 pounds full and 45 empty, he said.
But he still wakes before 4 a.m. to serve his customers, partly to keep the seltzer man tradition going. “These bottles are basically indestructible. I’m just their custodian,” he said...
