The world of wine is full of information, but sharing it can be difficult. LWIN assigns unique codes to wines, acting as bridge between systems across the trade so that they all speak the same language. Use it to add and exchange information automatically. Increase efficiency, improve accuracy, and reduce costly errors.

Efficiency and accuracy

The names given to wines are often inconsistent; one person’s “Chateau Lafite” is another’s “Lafite Rothschild”. 

While people can often – but not always  – understand this, digital systems can’t. A computer doesn’t know that these are the same wine, making it impossible to exchange information automatically. This explains why wine names are manually re-entered an average of 14 times as they travel through the supply chain, risking expensive errors.

Who is LWIN for?

LWIN is for anyone engaged in the business of wine: Merchants, trade bodies. government departments, competitions, publishers, warehouses, logistics suppliers, developers and apps. Any businesses that handles wine data can benefit from a universal naming convention for wine.

Who is LWIN for

A universal solution

LWIN standardises wine data by assigning unique codes to over 82,000 different wines. It’s a lot like the ISBN of the publishing industry. Each wine has a numerical code which can be shared automatically whenever you need to share information, from shipping instructions to adding critic reviews to your website. This eliminates the need to manually re-key, reduces errors, and simplifies reporting.

How long are LWIN codes, and what do they look like?

LWINs are unique 7, 11, 16 or 18-digit codes. The 7-digit code refers to the wine itself (i.e. the producer and brand, grape or vineyard). The longer codes include information about the vintage, bottle and pack size. 

  • LWIN-7: 1234567 – Example winery, Cabernet 
  • LWIN-11: 12345672012 – Example Winery, Cabernet, 2012 
  • LWIN-16: 1234567201200750 – Example Winery, Cabernet, 2012, 750ml bottle size* 
  • LWIN-18: 123456720121200750 – Example Winery, Cabernet, 2012, 12 bottles of 750ml 

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

Is LWIN the same as a product code?

No. Each wine has a universally relevant LWIN. Most merchant users contain both an LWIN and unique product code inside their system, which helps them to identify the wine (wine + vintage + bottle + pack size) and specific unique case or bottle. 

“Liv-ex has made a significant contribution to the world of fine wine by championing its LWIN unique identifiers for fine wines.”
