Frostbite

By Nicola Twilley

There’s a cold room somewhere in Washington state so vast, you could stack Mount Everest inside it. Not metaphorically — volume-wise. It’s a warehouse filled with sleeping apples, stored in a chilled oxygen-depleted atmosphere that presses pause on ripening. These apples were picked in autumn. Months later, they’ll be “woken up,” still crisp and dewy, ready to be sold in summer. They’ve time-traveled, and we don’t even notice.

That’s the world we live in now. Nicola Twilley’s Frostbite goes on ambitious journey of exploring this world hidden right in front of us, mostly unnoticeable unless you work in that industry.

Cold isn’t just temperature — it’s infrastructure. It’s history, design, culture, logistics. It’s the quiet background track of modern life. We’ve engineered ways to bend time, to shift seasons, to let strawberries show up in December and chicken thighs stay pink and plump long after the bird was alive. But it wasn’t always like this. Cold used to be a rare and precious thing.

Before refrigeration, preserving food was mostly about staving off anxiety. Every meal was a quiet little battle with decay. “Preservation is anxiety in its purest form,” Nicola Twilley writes, and the line lands like a truth you’ve always felt but never quite named. The old tricks — salting, drying, fermenting, pickling, burying in the snow — they weren’t quaint traditions. They were survival strategies. A jar of jam wasn’t just sweet — it was winter insurance. The root cellar wasn’t about rustic charm — it was what kept your carrots from going limp before February. You could plan, but you couldn’t quite relax. Except maybe with cheese. Cheese, Twilley says, is “milk’s leap into immortality.”

Then came ice, or a man named Frederic Tudor, who in the early 1800s got it into his head that he could sell cold. He cut blocks of ice out of frozen New England ponds, insulated them with sawdust, and shipped them to New York bars and restaurants. He gave away the first week’s worth for free. He knew once people tasted a cold drink, they wouldn’t want to go back.

It worked. Ice became addictive. And then it became infrastructure. Tudor even found a way to get shipping companies to carry his ice at a discount — they were running empty from Boston to New York anyway. At one point, he sold ice as a subscription. Yes, a literal subscription model for frozen pond water. And it worked. In Europe, ice was a decadent luxury. In America, it became ordinary.

The next big leap was meat. Before refrigeration, cities had to transport live cattle to local butchers — messy, expensive, and inefficient. About half of a cow was considered unusable at the time: bones, blood, guts. Once butchering became centralized, all of that “waste” turned into revenue streams — glue, fertilizer, animal feed. It changed how animals were processed, and who did the processing. Butchers, once skilled tradesmen, were now factory workers on an assembly line of death.

That shift happened thanks to Gustavus Swift. He figured out that if you put the ice at the top of a railcar, the cold air would sink, circulating through the meat. The railroads weren’t happy. They made more money transporting live animals by weight. But Swift stuck with it, and by 1880, refrigerated railcars were the future. The East Coast began eating cheap beef. And it didn’t stop there.

The ripple effects were global. Argentina and Australia turned into grazing economies. Ireland’s rural landscape, once hollowed out by British cattle interests, went back to being green and empty — which, in a strange way, helped fuel its independence movement. Cold didn’t just reshape meat. It reshaped land. Labor. National identity.

We’ve gotten so good at refrigeration now, it’s almost hard to see it. Apples can sleep in giant oxygen-deprived rooms for months and come out tasting better than if they had ripened on the tree. Salad greens sit inside plastic bags designed to let them breathe just the right amount — too much oxygen and they wilt, too little and they rot. Even bananas are gassed to ripen on command using ethylene — a molecule fruits evolved to release so animals would eat them and spread their seeds. Now we just bottle it.

A lot of this stuff used to be exotic. Jefferson and Lincoln probably never tasted a banana. The first time Americans saw avocados, they had no idea what to do with them. Too soft, too strange, too unpredictable. They require so much energy to ripen correctly that marketers didn’t just have to teach people how to eat them — they had to convince stores to even carry them. Now they’re everywhere. Sometimes five of them all ripen on the same Tuesday, but still — we made it happen.

And then there’s Coke. Here's one of my favorite bits: Coke is engineered to taste just right when it’s cold. Not at room temperature. The reason? Your taste buds — especially sweet, bitter, and umami receptors — basically stop working below 59°F. Cold mutes flavor. So if you want Coke to taste sweet when it’s cold, you have to make it even sweeter than it needs to be. That’s why warm Coke tastes like sugar syrup — it’s not defective. And because we drink cold soda with savory meals, our food is often sweetened too. A little bit of extra sugar in the BBQ sauce, in the bread, in the coleslaw — to keep up. Cold dulled our tongues, so we added sugar and salt to compensate. Eventually, we forgot what real tomatoes or fresh grapes actually taste like.

In fact, one newspaper back in the 1950s joked that the only consolation in all this was that the people who could tell the difference between fresh and refrigerated grapes were old and would eventually die. Brutal. But accurate.

What cold really did was reorganize everything. TV dinners rose, family dinners fell. One town in Idaho makes 15% of America’s French fries. Refrigerated trucks enabled monoculture farming — fewer crops, grown in massive scale, shipped long distances. The cost of refrigeration? About ten cents a kilo. That’s nothing in the West — about 1% of a tomato’s value. But in places like Telangana or Rwanda, that’s 30% of the cost. Same technology, totally different consequences.

GE loved refrigerators. Unlike a stove or toaster, a fridge draws power all day and night. It hums in the background. Constantly working. A steady low heartbeat of the modern home.

Inside the fridge, we tell stories about who we are and who we’re becoming. When families enter the middle class, their fridges start filling up with imported sauces and little indulgences. When they become affluent, everyone gets their own flavor of ice cream. One fridge might not be enough. You get a drink fridge. A party fridge. A garage fridge. And just like that, cold becomes aspiration.

The fridge became the boundary between past and future. It replaced the root cellar. It replaced the icebox. It changed what we eat, when we eat, how we plan, how we waste. And yeah — about 30% of our food gets wasted. Mostly because it gets lost in the back of the fridge, waiting for us to rediscover it three weeks too late.

Cold let us master the seasons. And in doing so, it quietly remade the world. It made summer, food-wise, possible all through the year for much of the planet.

A dense book packed with some little stories.

Highly recommended.
