LWIN enables systems to communicate efficiently – and reduces the risk of human error.

Use it to…

You can use LWIN to increase the efficiency and accuracy of fine wine transactions.

The fine wine market has long suffered from problems associated with complex product names. “Grange” for example, is widely understood as “Penfolds”, despite there being over 200 wines with “Grange” in their title.

For humans it is possible (although not always) to understand the subject matter. The same cannot be said for computers. Very rarely is the full name of a wine used. Even less frequently is it written or keyed consistently in every system, document or form when fine wine is created, transported, marketed, bought, sold or stored. In fact, details of wine are commonly recorded more than ten times for a single transaction and repeated many times over in the life of a wine.

LWIN – unique seven-digit codes – introduce a simple and consistent naming convention for fine wines into your systems.



  • Improve database accuracy
    Wine naming conventions are simplified and standardised using unique seven digit numerical codes – a language easily understood by computers
  • Revolutionise supply chain efficiency
    Details of wine are commonly recorded more than ten times for a single transaction and repeated many times over in the life of a wine. LWIN ensures that everyone in the chain is speaking the same language
  • Reduce costs and increase profitability
    Save time on rekeying – and avoid expensive mistakes.


How it looks

Each L-WIN refers to the wine itself (i.e. the producer and brand, grape or vineyard). The first six numbers of the code represent each wine’s unique identifier, while the seventh number is a “check digit” that minimises input errors.

Additional information, such as the vintage, pack and bottle size can be appended to the L-WIN in a standard format, or added as separate fields.

The L-WIN standards for including additional data are:

  • L-WIN: 1234567 – Example winery, Cabernet
  • L-WIN-11: 12345672012 – Example Winery, Cabernet, 2012
  • L-WIN-16: 1234567201200750 – Example Winery, Cabernet, 2012, 750ml bottle size*
  • L-WIN-18: 123456720121200750 – Example Winery, Cabernet, 2012, 12 bottles of 750ml

*All bottles sizes are expressed in millilitres in a five-digit format.
