So Hardcore! Tai Er Officially Launches Pickled Vegetable Latte and Pickled Vegetable Fish Coffee!

Yesterday, yet another wave of sauerkraut latte photos took over our coffee group chat!

At first I assumed everyone was just chasing a rumor — but no: Tai Er (yes, THAT sauerkraut fish restaurant!) really did launch a sauerkraut latte. And this was no joke...

It started back on April Fool's Day, when Tai Er announced it had founded a coffee company and unveiled the "world's first sauerkraut fish coffee." Using sauerkraut fish cooking techniques and ingredients, they mocked up several intriguing drinks: an ice-blog sauerkraut latte, a sour-and-refreshing iced Americano, a wasabi shrimp cappuccino, a boneless chicken feet cappuccino, and more.

Except it was all an April Fool's gag — no coffee shop, nothing for sale. Netizens joked at the time: if you're adding sauerkraut, why not add the fish too?

Since nobody could buy it, people started DIY-ing it. For the next month, the group chat filled with homemade sauerkraut coffee experiments — even this writer ground coffee beans into particles for a unique attempt. It was satisfying to make, and the cleanup was equally memorable.

Then, months later, came the real thing: an actual sauerkraut latte — and even sauerkraut fish drip coffee bags. Utterly outrageous.

The launch also included several other drinks: a chrysanthemum lemon coffee, a tangerine peel cold brew, a hibiscus iced Americano, and a (hua)jiao pepper passion fruit Americano. Not quite as wild as the April Fool's lineup, but still impressively audacious.

What Does Sauerkraut Latte Taste Like?

So what does the real sauerkraut latte actually taste like? "It doesn't taste like sauerkraut! And it's surprisingly delicious! It's just a latte with a slightly sour edge," report friends who've tried it.

(I can see everyone's disappointed expressions through the screen.) Don't be! If they'd used genuinely tart, pungent sauerkraut, the flavors would clash — and worse, the acidity would curdle the milk.

The Sauerkraut Fish Drip Coffee

The sauerkraut fish drip coffee, though, really is sauerkraut fish — at least on the packaging. Anticipating that fans would feel cheated by a sauerkraut latte without sauerkraut flavor, the brand styled the drip bags to look like plates of sauerkraut fish. And the coffee inside isn't plain either: it's infused with tangerine peel.

The Marketing Genius Behind This Collaboration

From Guo Degang's crosstalk bit about "drinking coffee with garlic" to a sauerkraut fish chain "pouring latte over pickles," Tai Er's idea sounds absurd — and that's exactly what makes the crossover marketing clever.

Brand-coffee collaborations are nothing new. In recent years, countless seemingly unrelated brands have teamed up with coffee hoping to attract new customers, with mostly mediocre results. The usual failure: forced pairings, no warm-up, no conversation topics.

Had this sauerkraut-fish-coffee combo launched cold, the reaction would likely have been overwhelmingly negative — it looks "unreliable" at first glance. But leaning into the absurdity and planting the seed on April Fool's Day was a smart play.

They got a free read on consumer sentiment toward the concept, while everyone who couldn't try it kept thinking about it. Then, right as the buzz cooled but imitation was still going strong, the real product dropped — triggering a fresh wave of curiosity-driven purchases.

And the products themselves show real effort. Making boldly flavored ingredients work with coffee is no small feat.

Crossover collaboration is about exchanging audiences: you have the customers I need, I have the customers you need; we expand and blend, and eventually convert. Both sides tell the same story, consumers resonate, and brand awareness grows quickly.

By those measures, this collaboration was, to a real extent, a success.

FrontStreet Coffee Recommendation

Meanwhile, if you just want a classic cappuccino done right, FrontStreet Coffee has the beans. The Classic Blend is the crema bomb: designed for espresso machines and moka pots, it produces thick, velvety foam even for beginners, with a mellow, warming body. The Dark Cocoa Base Blend is the value pick — 100% arabica, generous crema, smooth and rich, easy on the wallet.

For something fruitier, the Strawberry Candy Espresso Blend recreates strawberry gummy sweetness — berry, rose, raisin, and candy notes under thick milk foam — while the natural-process, medium-roast Granana Gesha SOE stays bright and bitterness-free, with berry, orange, and persimmon flavors that turn to creamy toffee with milk. FrontStreet's cappuccino method: extract 20g of coffee to a 1:2 ratio in about 30 seconds, foam the milk extra thick, spoon a dome of foam into the center, then pour to the brim — the golden ring is all yours.
