Here is a complete introduction to Nongfu Spring’s Tan Bing (tàn bīng) ready-to-drink coffee, covering the product line, flavors, process, specs and photos to help you choose precisely.

Brand & process background
Tan Bing launched in 2019, positioned as a mid-to-high-end RTD coffee. Its core process is self-roasting and self-extraction with no instant-powder use: it selects Arabica green beans, roasts them at the factory, rests the beans for 3 days, extracts by espresso, and cans the extract within 24 hours. The room-temperature aluminum can / bottle needs no cold chain, with a 9-month shelf life, suitable for both hot and cold drinks (heat below 55°C).

Core product line (270ml aluminum can, main spec)
1. Unsweetened Black: single-origin beans from Brazil’s Monte Alegre estate, 0 sugar 0 calories 0 fat; rich on entry with caramel aroma and a clean finish; suits sugar-control, fitness, and long-drive alertness.

2. No-added-sugar Latte: Arabica + quality milk, no extra sugar added; mild milk aroma, mellow coffee, roasted finish; commute / breakfast friendly.

3. Low-sugar Latte: a light-sugar formula with restrained, not cloying, sweetness; higher smoothness, balancing flavor with a light burden; for coffee newcomers and those who dislike bitterness.
New 400ml PET bottle (launched end of 2025; value / large-capacity scenarios)
Two flavors—Classic Black and Classic Latte—with the same fresh-extract process, suited to offices and RV / road-trip scenarios that need larger volume, at a more affordable price.

Key supplementary information
Storage: keep at room temperature in a cool, dry place away from sun / freezing; refrigerate after opening and finish within 24 hours.
Purchase channels: available at convenience stores, supermarkets, and JD / Tmall Nongfu Spring official flagship stores. The 270ml can is about RMB 8–10 per unit; the 400ml PET bottle about RMB 5.
Naming meaning: “Tan” (charcoal) refers to charcoal-roast; “Bing” (an ancient character meaning ice) corresponds to low-temperature extraction—together emphasizing the flavor balance of combined hot-and-cold process.
