How to Check Production Date and Shelf Life of Indonesian Coffee Beans? How Long Can Coffee Beans Generally Last?

Reading Dates on Indonesian Coffee Packaging

Plenty of people buy an Indonesian Mandheling only to find the production date and expiry date impossible to decode. Here is how the labelling works. In Indonesia, "processed food" covers any food or beverage that has been treated in some way or method, with or without additives, and processed-food labelling means any picture, text or combination of the two that describes that product.

Information Required on the Label

Processed-food labels must carry the following:

• Product name
• List of ingredients
• Net weight or net content
• Name and address of the producer and importer
• Halal designation
• Date and production code
• Expiry day, month and year
• Processed-food distribution licence number

Where the product is sold commercially or used as an ingredient in other foods, the label must at minimum show the product name, net weight or net content, the name and address of the producer and importer, the date and production code, and the expiry information.

Processed foods may also carry nutrition claims (nutrient content and comparative claims), health claims (nutrient function, other function and disease risk reduction claims) and other claims such as isotonic, no sugar added, lactose and gluten claims.

Production Dates and Shelf Life in Detail

The rules around dates are more granular than most buyers realise.

Labels require both a production date and a code, and the code may be expressed as a batch number. The production date can be printed separately from the code, but the label must then explain where the production code can be found. In practice the production date usually sits on the bottom of the can or on the cap.

Expiry information should state the day, month and year, with two thresholds:

• If the shelf life is 3 months or less, the expiry must include the day, month and year.
• If the shelf life exceeds 3 months, the day becomes optional, but the month and year are mandatory.

The order of the numbers is always day, month, year.

Decoding the Date Terminology

• Best before marks the best-flavour period.
• Exp means the expiration time.
• Use by / use before means consume before this date, that is, the expiration time.
• Production Date means the manufacturing date.

Storage Advice from FrontStreet Coffee

When FrontStreet Coffee runs a promotion, enthusiasts often stock up in bulk, including very expensive Geisha and Indonesian Kopi Luwak. The advice is simple: always check the roast date before buying. Every bag FrontStreet Coffee ships carries its roasting date printed on the packaging. Coffee beans generally reach their flavour peak 3 to 7 days after roasting, during the de-gassing window, and then decline gradually. The broad optimal tasting period is 4 to 30 days. Past that window the coffee is not undrinkable, it simply loses some of its edge. Roasted beans typically keep for six months to one year. And if you have overbought, there is an easy solution: give the surplus to people you like.

FrontStreet Coffee Recommendation

FrontStreet Coffee's PWN Golden Mandheling is the benchmark for buyers who want Indonesian character at its cleanest. Produced by PWN, it is built on beans of 18 mesh and above, with fewer than 3 defective beans per 300 grams of green coffee, which meets the top G1 standard, and it passes through three rounds of hand sorting to remove every remaining defect. The result is a markedly cleaner, sweeter cup than ordinary Mandheling, with a limited annual supply and the PWN certificate and branded bags that confirm its origin.

FrontStreet Coffee's Lintong Mandheling shows the wilder side of the island. Grown around Lake Toba in the Lintong region of North Sumatra and processed by the wet-hulled method, it is roasted medium-dark to soften the acidity and emphasise body: black chocolate and caramel layered over the herbal, woody, clove-like notes that wet-hulling creates, with a long, thick, sweet finish.

If you want that Mandheling depth in an espresso or moka pot, FrontStreet Coffee's Classic Blend is the practical choice. It layers medium-dark Mandheling over the creamy, nutty base of Brazilian coffee, so butter, roast chestnut and caramel lead, while the Mandheling adds sandalwood, herbal and spice notes and lifts the overall body. A small proportion of Robusta further increases the crema, making latte art and Dirty layering straightforward.
