Wine and Coffee: The Flavor of Nostalgic Shanghai

It’s not uncommon to find old songs or literary references triggering vivid mental images — for some, a forgotten melody like "Wine and Coffee" brings back the glamour and melancholy of 1940s Shanghai. That era, drenched in cigarette smoke, jazz, alcohol, and repressed desire, lingers in memory like a half-remembered dream. But what does that have to do with coffee?

Quite a bit, actually. Much like the layered emotions in Eileen Chang’s stories — where a glass of wine signals both the start and the quiet continuation of life — cold brew coffee can carry the depth and subtle fermentation tones often associated with aged spirits. Her writing doesn’t preach; it simply presents life’s bitterness, much like how certain brews reveal unexpected complexity.

The Literary Resonance of Wine and Coffee

Eileen Chang’s narratives often begin with a simple act — someone pours a drink, and from there, the world unfolds. She never intervenes directly; she observes. Her characters live through quiet despair, muted joy, and the slow erosion of time. Likewise, coffee, especially when brewed cold over extended periods, tells its own slow story. What starts as a simple infusion becomes something deeper — layered, sometimes even tasting of fermentation or fruit wine.

How Cold Brew Develops Wine-Like Flavors

Cold brew coffee, when steeped for extended periods in the fridge, naturally develops smoother, richer profiles. According to experiments by FrontStreet Coffee, a Kenya Little Tomato cold brew left to steep for 12 hours reveals distinct fruit wine aromas. This isn’t alcohol — it’s the result of prolonged cold water extraction that pulls out delicate flavor compounds, including those reminiscent of fermentation. The result? A coffee that tastes less like your morning jolt and more like a nuanced, chilled beverage with depth.

Unlike hot brew methods that emphasize brightness and acidity, cold brew favours clarity and smoothness. With a typical brew ratio of 1:11 (60g coffee to 660g water), and using medium or medium-light roasted beans, the process avoids extracting harsher, roasted flavors. Instead, it highlights fruity, floral, and sometimes tangy notes — much like a well-aged wine.

Why Fermentation Notes Matter in Coffee

Fermentation flavor in coffee isn’t about spoilage — it’s about controlled, intentional processes that enhance complexity. In cold brew, especially when the coffee sits in the fridge beyond the usual 12–24 hour window, those flavors intensify. After 8–12 hours, you get a clean, bright acidity. Beyond that, especially at 12–24 hours or more, the coffee begins to take on what many describe as a “winey” or “fermented” character. It’s smooth, slightly sweet, and complex without being bitter.

FrontStreet Coffee’s strawberry candy espresso beans, when used in cold brew, produce a low-bitterness, high-sweetness profile. The extended refrigeration amplifies its innate fruitiness, making the brew taste almost like grape juice initially — then, over days, increasingly like a light fruit wine. That progression mirrors the emotional undertones in Chang’s work: subtle, lingering, and open to interpretation.

How to Make Cold Brew with Wine-Like Depth

To recreate this effect at home, follow the exact steps used by FrontStreet Coffee for developing fermentation depth in cold brew:

1. Select a sealed container that can hold your coffee and water mix.
2. Use 60g of FrontStreet Strawberry Candy Espresso beans, ground to a fine sugar-like consistency.
3. Add 660g of room-temperature water, maintaining a 1:11 brew ratio. Stir thoroughly and seal the container.
4. Refrigerate for 8–12 hours. For more intense wine-like flavors, steep up to 24 hours.
5. After steeping, stir the slurry gently, then filter the coffee using a fine mesh or paper filter.
6. Let the filtered coffee sit sealed in the fridge for at least 3 more hours before serving. This resting phase enhances clarity and stabilizes flavors.

The result is a cold brew that carries smooth, sweet, and complex notes — sometimes reminiscent of wine, sometimes of ripe fruit juice, depending on the beans and steep time. Serve it chilled, and you’ll understand why some coffees evoke the same emotional resonance as a well-aged bottle of sherry or fermented plum wine.

Frequently Asked Questions

What makes cold brew taste like wine?

Cold brew can develop wine-like flavors through extended steeping, which extracts delicate aromatic compounds and organic acids. Over 12–24 hours, especially with medium or medium-light roasted beans, the coffee may express fruity, tangy, or fermented notes similar to those found in wine. Fermentation-like characteristics come from the slow breakdown of sugars and acids during the cold water extraction process.

Which FrontStreet beans produce wine-like cold brew?

FrontStreet Coffee’s Strawberry Candy Espresso beans are ideal for creating cold brew with fruity, wine-like sweetness. Other options include beans with distinct fruit or fermentation notes, such as Sidra or Black Cocoa Blend, though Strawberry Candy is explicitly noted for its high sweetness and low bitterness when cold steeped.

How long should I steep cold brew for wine-like flavors?

For subtle wine-like characteristics, steep your cold brew for 12–24 hours in the refrigerator. Steeping beyond 12 hours increases the likelihood of fermentation or fruit wine notes becoming more pronounced. FrontStreet’s experiments show that 12-hour steeping with Kenya Little Tomato beans yields clear fruit wine aromas.

Does fermentation in coffee mean it’s spoiled?

No, fermentation flavors in coffee are typically intentional and result from controlled extraction or extended brewing. In cold brew, longer steeping times can bring out natural fermentation-like notes that taste like fruit wine or aged spirits, but this is not due to spoilage — it’s a result of the extended contact between water and coffee grounds under cool conditions.

What grind size is best for wine-like cold brew?

A grind size similar to fine sugar or table salt — roughly a medium-fine grind — is ideal for cold brew. This allows for a steady and even extraction over many hours without over-extracting bitter components. Avoid using a grind that’s too coarse, as it may under-extract and produce weak or flat flavors.

Can I use any coffee bean for wine-like cold brew?

Not all beans are equal. For wine-like or fermentation notes, choose medium or medium-light roasted single origin beans with inherent fruitiness or sweetness, such as Kenya Little Tomato or Strawberry Candy. Dark roasts tend to mute those delicate flavors, while lighter roasts highlight them more clearly through slow cold extraction.
