Brew‑haha in aisle three
A brief history of instant coffee
From war “axle grease” to USB‑C kettles, the instant coffee fight is on
TLDR: The article traces instant coffee’s messy path from rancid fat “cakes” to a true powder via late‑1800s hot‑air drying. Commenters turned it into a culture war: price rants, kettle speed jokes, and an Australia‑vs‑America taste smackdown, with budget hacks and wartime nostalgia brewing a surprising defense of instant coffee.
Instant coffee’s glow‑up has the comments buzzing harder than a triple shot. Readers loved the wild origin story—early “coffee cakes” made with butter and tallow that went rancid, Civil War sludge compared to “axle grease,” and the eventual breakthrough when a New Zealander pioneered hot‑air drying to make real powder. But the real brew‑haha? People are passionately defending their morning shortcut.
One thrifty hacker swore by DIY mochas—stirring instant into hot chocolate—because the “cost‑caffeine ratio is sooooo much better.” Another joked it’s “never instant” because waiting for water to boil is eternal suffering, cue Brits flexing faster kettles and someone begging for a USB‑C kettle. Meanwhile, a UK shopper called out marketing theater, saying their supermarket “instant” is freeze‑dried and often pricier per kilo than local beans. Across the pond, an Australian declared instant beats most American diner coffee—cue the burnt drip slander—while others admitted they’d pick espresso if given the choice.
Nostalgia also hit hard: a wartime letter praising “George Washington Coffee” turned into a meme about offering nightly prayers to Mr. Washington. It’s a redemption arc for instant coffee: from rancid fat cakes to respectable pantry staple—depending on your kettle voltage and your budget.
Key Points
- •Instant coffee’s development was hindered by the need to preserve volatile flavor compounds while removing water.
- •In 1771, John Dring’s fat-based coffee cakes spoiled quickly due to rancidity, making them commercially unviable.
- •In 1840, T & H Smith’s ‘coffee essence’ was a molasses-like concentrate made by reducing brewed coffee and adding chicory and burnt sugar.
- •Civil War-era U.S. efforts included a condensed coffee-and-milk concentrate from HA Tilden & Co., which reduced weight but was unpopular.
- •In 1889, David Strang introduced a Dry Hot-Air method that dehydrated coffee below boiling, producing the first viable instant coffee powder.
