How To Decode Sherry Bottling Codes

by Tim Elliott on February 16, 2011

Sherry back labelToday is Wine Blogging Wednesday 70 and I’ve chosen Sherry in keeping with the theme of Spanish wines we have never had before. Sherry has a lot of issues gaining mindshare with the American consumer but one of the most basic is turnover of stock since some Sherries – Fino and Manzanilla in particular – are best within the year they were bottled. Even other styles which will hold in the bottle for years have a shelf-life that consumers should be aware of.

The problem is Sherry is not vintage dated but a blend of many years slowly aging in the solera. Each year a portion is drawn from the bottom barrels and bottled. For commercial reasons Sherry producers stamp a bottling code on each bottle as it comes off the line. This allows importers and retailers to rotate stock but remains somewhat cryptic for the consumer. But once learned you can use this information to make a more informed buying decision.

The two most common coding systems start with an “L” printed on the back label along with a 4 or 5 digit number. In the 4 digit code, the first digit after the “L” indicates the year followed by the day of the year the Sherry was bottled. So the “L7137″ code on the bottle pictured here translates to the 137th day of 2007, or May 17, 2007. If the bottle has 5 digits after the “L” then the first 3 digits indicate the bottling day and the last two are the year. So “L18409″ would indicate the 184th day of 2009, or July 3, 2009.

There are some other variations of these codes but 90% of the time here in the U.S. you will see the two listed above. The best writeup I’ve seen online on this is over at the Wine Lover’s Page but for some reason it didn’t turn up when I searched on my phone in the store. I wish it had since the Amontillado selected for tonight’s tasting is almost 4 years in the bottle, more than likely at the end of it’s life. Of course it could also be fine as some others have noted. We’ll see a bit later on.

My friends at Catavino have another helpful post about this subject that includes a handy freshness chart:

  • Fino/Manzanilla: Consumed no more than 12-18 months after bottle date and no more than 1 week after opening.
  • Amontillado/medium: Consumed no more than 18-36 months after bottle date and no more than 2-3 weeks after opened.
  • Oloroso/Cream: Consumed no more than 24-36 months after bottle date and 4-6 weeks after opened.
  • Pedro Ximenez: Consumed no more than 24-48 months after bottle date and 1-2 months after opened.

    I have a same sherry, but I in confusion: bottling Code L.1066 – what bottling date?

  • Boris

    And again hello!
    From code L.1066, using the converter, I’ve defined the following date: March 7, 2010.
    I’m so glad! There is a hope that the sherry wasn’t lost yet!

      You are correct but if the Sherry is a Fino or Manzanilla you should drink up as they are best within 6 months of bottling.

    • Palo Cortado

      L1066. Not sure how you get March 2010. This is either yddd or dyyy. Depending on the bodega.

      So either day 66 (early March) 2011, or day 106 (Mid April) 2006. The former more likely by this time.

    My bottle of La Gitana had lot code L-01703 12:50. Am I right in decoding it as 17 Jan. 2003? I asked 5 different wine experts/aficianados at my local wine outlet but none were familiar with lot codes on sherry. I bought it anyway because I have never tasted Manzanilla and I really had my heart set on La Gitana Manzanilla. When I nosed it I found a muted yeasty nut-like and citrusy aroma.  I don’t know if I was imagining it but I thought I could smell the ocean. On the palate the taste was dry with some saltiness and  hints of Spanish olives, sardines and licorice. The finish was long and astringent. It was similar but different and  richer than the finos I’ve had. I really liked this wine and will buy it again. 

    • Palo Cortado

      No! L 01703 on La Gitana means

      Year 0 (2010)
      Week 17 (Late April ish? Count your calendar if it matters)
      Day 3 of that week (Tues or Weds, not certain)

      La Gitana have a ywwdd system all of their own.

    I have a bottle of 1971 Don PX Gran Reserva and don’t understand the codes on the back.

    The “L” is L-16345 and the other is BT:1-617889

    I could find any explanation for PX, just sherries, thanks!
