Last month, Brad Reese — grandson of the man who invented the peanut butter cup — bit into a Reese's Valentine's Day heart and posted an open letter to Hershey. The chocolate coating, he said, wasn't chocolate anymore. It tasted cheap. It tasted wrong.
Within days, the story was everywhere. Not because a candy heir was upset, but because millions of people recognized the feeling. That quiet moment when something you've eaten your whole life tastes different, and no one told you why.
Hershey had swapped milk chocolate for a compound coating on several seasonal products — a move almost certainly driven by cocoa prices that have surged by 400% in the past decade, as climate-driven droughts devastated harvests across West Africa, where the majority of the world's supply is grown. The company said the classic Reese's cup itself hasn't changed. That may be true. But the fury wasn't really about one product. It was about the feeling of being quietly deceived by something familiar.
This keeps happening. And it's never about what we think it's about.
In 2016, Toblerone widened the gaps between its iconic chocolate peaks to reduce weight as ingredient costs climbed. It trended higher on Twitter than any topic except the US presidential election. People called it "austerity Toblerone." No one talked about cocoa supply chains.
When back-to-back droughts in Brazil and Vietnam crushed coffee yields, even premium brands were caught quietly substituting cheaper Robusta beans for the Arabica on their labels. Lab tests exposed what taste buds had already suspected, and consumers blamed corporate greed. The harvest failures that forced the switch barely made the conversation.
Bordeaux has quietly authorized six grape varieties that were previously banned from its blends, because rising temperatures are making its traditional grapes produce unbalanced wines. Sommeliers notice. Consumers blame the winemaker.
We are living through a period in which climate change is arriving not as a dramatic event most people can point to, but as a slow degradation of things they love. A chocolate that tastes a little off. A wine that lost its crispness. A coffee that's not quite what it was. The changes are small enough to notice but hard to explain, and in the absence of an explanation, we reach for the most available story: the company got greedy.
That story is almost always wrong — or at best, incomplete. The more accurate version is harder to sit with. The ingredient your grandmother used, the flavor you grew up on, the product that felt like it would never change — it is changing because the agricultural systems that produced it are under stress that is not going away.
This is, in a sense, an anthropological phenomenon. Climate change has been discussed for decades as a matter of science, policy, and politics. But for most people, it doesn't arrive as a carbon parts-per-million number or an IPCC report. It arrives as a broken promise from a brand. A taste that shifted. A price that jumped. A package that got smaller. We process planetary disruption through the most intimate lens available to us: the things we eat.
And so the outrage is real, but misdirected. We are, collectively, grieving changes we don't fully understand by blaming the nearest visible actor. The company becomes a proxy for a system-level failure no single company created.
The harder question is what comes next.
When a key ingredient becomes unreliable, any company in the food industry faces the same brutal trilemma: raise prices and lose customers, shrink portions and hope no one notices, or substitute quietly and pray the taste holds up. These aren't good options, but they're the only ones available within a system built on the assumption that agricultural inputs would remain stable and cheap.
Well, that assumption is breaking. Cocoa is the headline today, but the same dynamics are playing out across fats and oils — ingredients responsible for roughly 7% of global greenhouse gas emissions, on par with every car on the road. Butter prices have more than doubled in the past decade, along with coconut oil and palm oil. Not to mention how palm oil carries well-documented environmental and human rights risks that make sourcing increasingly complex.
The ingredients that give food its richness, texture, and indulgence are simultaneously becoming more expensive, less predictable, and more ethically fraught to produce.
The food industry has spent generations getting extraordinarily good at optimizing within a system it inherited. What it hasn't done — what no individual company can do alone — is build alternatives to the system itself. That work is beginning, but none of us are at the scale the world needs yet.
The question the Reese's backlash really asks isn't "why did Hershey change the recipe?" It's whether the food system can move fast enough to give companies better choices before the next ingredient fails — and the next, and the one after that.
The peanut butter egg is a small thing. What it represents isn't. And until we start seeing these moments for what they are — not corporate betrayals, but climate symptoms — we'll keep having the wrong argument while the real problem grows.
