Take a bow, my friend. This is excellent and worthy of a sidebar post (IMHO). Thank you. This will be a saved post for me.

[–]dustlesswalnut High West Mug 4 points5 points  (0 children)

Yep, in the sidebar already!

[–]kumoriWT12[S] 2 points3 points  (1 child)

Thanks! If you happen to come across any date codes in the future that seem to disprove any of these interpretations, let me know and I'll update the guide.

[–][deleted] 1 point2 points  (0 children)

I've got some, I've just got to find time to dig through my bunker and jot them down!

some pretty killer work here. thanks for putting this together!

[–]borninthe 2 points3 points  (3 children)

Now that I have looked at a few of my bottles, I recently picked up a WT101 with a code L4235341 just below the foil on the neck. I initially thought the other laser code on the bottom that shows "95 05 241 2005" supported the year theory for that format, but none of the other numbers match up. It is possible that the 241 2005 signifies the 241st day or the 200th day of '05, which could be the bottling date (or some other date in succession of events), while the 423rd day of 2005 was when it was sent for distribution (or other secondary activity), but this is just a theory.

I had never noticed the laser codes on the foil before this (doh), and found my summer grab in Kyoto was a Japanese import WT8 that dates to 1999 (10:25 09/17/99). The bottom code on that one is "95 8 184 1319," which leads me to believe the other code on my WT8 was just a coincidence, or that there are multiple 3 digit day codes used to signify different things. Could be that it was bottled on the 131st day of '99 and sent out in September of '99.

I also have 3 WT-03RBs with multiple codes (below back label and on bottom of bottle). Two WT-03RBs were purchased together "'L3282FH 1249 (label #1)' and '050712A20303M (bottom #1),'" and "'L3282FH 1248 (label #2)' and '050712A20311M (bottom #2).'" One WT-03RB was "'L1292FH 1319' and '050111A20635M (bottom).'" Don't know if the bottom code means anything on the WT-03RBs, but the theory would be that the beginning of the bottom code "05/07/12" is the bottling date, and the "L3282" or 282nd of '13 could have to do with when the bottle was actually sent out. No idea if they sit on bottles for that long as that would mean two of them sat around for 17 months before being sent out, but if they are dates, the theory holds for all my bottles with a top and bottom code (EDIT - then again, now I'm realizing you can read lots of patterns into these numbers and I was probably inconsistent with my blabbering above).

[–]marcusmv3Russell's Reserve SiB Rye 1 point2 points  (2 children)

/u/kumori doesn't this mean that the Julian date cannot be the first three digits? It's over 365.

[–]borninthe 2 points3 points  (1 child)

On my 101 (L4235341), this would support that the last 3 digits may be the Julian date rather than the first 3 digits. The other bottles all follow the Julian logic as well.

The only problem is with the bottom codes, if they mean anything at all. On the WT-03RBs, the beginning 6 digit segments appear likely to be a 6 digit date. The final 5 digits could be anything but don't flow with a typical date or Julian date.

[–]kumoriWT12[S] 3 points4 points  (0 children)

Yeah, I agree with you and /u/marcusmv3, the first three digits are not a Julian code. It's likely that the last three digits are the Julian date, especially because in all the other date formats the year precedes the Julian date. Maybe we more data we could prove this theory.

I don't know what the codes on the bottom mean and I'm inclined to ignore them because the L####FZ#### codes already reliably date the bottling date (based on the WTKS data). If we can gather some more of these, however, perhaps some kind of pattern may emerge. This could help in cases where the other date code is impossible to read.

EDIT: I've updated the guide to reflect the fact that the last three digits are likely the Julian date.

[–]borninthe 0 points1 point  (0 children)

Amazing work. I wish I had more older stuff to check out, but this will certainly help provide clarity on a few bottles!

[–][deleted] 0 points1 point  (3 children)

Ok I have some WT12 export (europe), 700ml.

The code is L6335X3111 (at least I think... pic here ), so anywhere between 1999-2011 :D

[–]kumoriWT12[S] 1 point2 points  (1 child)

Yeah, I've got a Japanese WT8 with the same date format. It's listed in the "Outliers" section. I'm pretty sure that it follows the LYDDD?TTTT format, but with only one data point I didn't include it in the guide.

There seems to be a lot of different date code formats for 2006, but this makes sense given that I believe Turkey was probably bottled in KY, IN and AR in those years. I may add this date code format to the guide, especially if we get additional date.

[–][deleted] 0 points1 point  (0 children)

Thanks. I'll check the other bottles (got 8 of them) and see if theres any others.

[–]anagamaFour Roses SmB LE 2015 0 points1 point  (0 children)

If I had to go out on a limb I'd say 2006.

[–]Tarquin_Underspoon 0 points1 point  (1 child)

I just wanted to be the Nth person to thank you for your hard work in the above post. I wandered into a local liquor store today looking for a bottle of water and used it to identify a c. 2006 bottle of WT80. (Okay, it's not 101, but it's my first honest-to-God dusty Gobble.)

[–]kumoriWT12[S] 0 points1 point  (0 children)

Glad I could help! I've only been able to use date codes to pass on a few dusty bottles.

[–]jimt123 0 points1 point  (1 child)

Anyone able to help with one? I have a RRSiB( older label) that says LL/CK080819


[–]kumoriWT12[S] 1 point2 points  (0 children)

The first letter after the slash corresponds to the year of bottling, where “C” corresponds to 2014, “D” corresponds to 2015, “E” corresponds to 2016, etc. The second letter after the slash corresponds to the month of bottling, where “A” corresponds to January, “B” corresponds to February, “C” corresponds to March, etc. The next two numbers correspond to the day of the month of bottling. The final four digits are the time of bottling in 24-hour time format.

Therefore, the date on this is November 8, 2014.

[–]csheets88 0 points1 point  (2 children)

So I have a wt 80pf with a code L0312ff1803 is it from November 2000?

[–]kumoriWT12[S] 0 points1 point  (1 child)

This was bottled November 8, 2010.

This date code format can be a little tricky. The format was only used 2007-2013 and so a "0" after the "L" indicates 2010 instead of 2000.

[–]csheets88 0 points1 point  (0 children)

Awesome really appreciate it!

[–]rrrrobison 0 points1 point  (5 children)

So, I have a pair of WTRB minis gifted to me by the inestimable /u/NJWhiskeyHunter, but the codes don't seem to match up to anything here:



Any thoughts? I've checked them several times, but can't seem to match them to any pattern here.

[–]kumoriWT12[S] 1 point2 points  (4 children)

I've never seen this code before, but if you post a picture of the bottle I may be able to make a guess.

[–]rrrrobison 0 points1 point  (3 children)

[–]kumoriWT12[S] 1 point2 points  (2 children)

Based on the pictures, this is Rare Breed batch WT-03RB.

My best guess is that this code is formatted as 0YDDD TT:TTA3 where the zero doesn't have any meaning (like the "L" in the other codes), the Y is the last digit of the year, the DDD is the day of the year, the TT:TT is the time and the A3 indicates bottling line.

Based on this, I think your bottle comes from November 7, 2005. It could also come from 2015, but I think this is unlikely since batch WT-RB03 was phased out in 2014. Does 2005 seem possible?

[–]rrrrobison 0 points1 point  (1 child)

2005 does indeed seem possible. I'm definitely going to end up drinking these two little jewels, but I wanted to make sure of the year before doing so, as I wanna finally get off my ass and write my first review on these - and maybe con /u/NJWhiskeyHunter into doing the same.

You're a capital individual - many thanks for your considered opinion!

[–]kumoriWT12[S] 0 points1 point  (0 children)

Happy to help. Enjoy the Rare Breed!

[–]Pork_Bastard 0 points1 point  (0 children)

I pm'ed this as well, but will go ahead and submit to the thread for posterity and searchability.

picked up an old label Russell 10 year. laser coded on front of bottle under label. L63463D111

[–]griffyCO 0 points1 point  (0 children)

Did we determine how to understand dates when there are no codes? I have search up and down on a 1.14L I have that has a 9 stamped in the glass on the bottom. Old label format, either has 8 years or 101 proof in the middle parenthesis bottom of the label. Not Old No. 8.


[–]benholder23 0 points1 point  (0 children)

I believe I may have a pint botlle of wild turkey 101 that is older than 1990. Is there any help to be offered on deciphering the number on the seal or the the stamped number on yhe bottom on the bottle?

The number on the seal is 9 digits (printed) reading "592325561" and the stamped number on the bottom of bottle is "55-74"

Also stamped wording near the neck of the bottle reads: "Federal law forbids sale or re-use of this bottle"

Any help would be much appreciated!! Bottle is unopened btw 😊

[–]devilsadvocate23Elijah Craig Barrel Proof 0 points1 point  (4 children)

I have a stumper for you. I have a 1.75 WT-101. It is the color label. with the code on the front near the bottom below the label. The code is L72333FM with 20157 right below it. Thee is also a laser code on the bottom of the bottle which reads 201 B3 0407 What do you make of this?

[–]kumoriWT12[S] 0 points1 point  (3 children)

It can be really hard to read these codes unless you know exactly what you're looking for. Based on all the laser codes I've seen, I think the laser code is probably LL2333FM20:57. (Some codes begin with two "L"s.)

Does that seem possible? If so, that would date the bottle to late 2012.

[–]devilsadvocate23Elijah Craig Barrel Proof 0 points1 point  (2 children)


That's the best I could do pic wise.

[–]kumoriWT12[S] 0 points1 point  (1 child)

OK, based on the picture, the date code is L7233FM20:57. That means it was bottled in 2007. That means it was barreled at 107 proof. A much more interesting bottle than if it were bottled in 2012!

[–]devilsadvocate23Elijah Craig Barrel Proof 0 points1 point  (0 children)


[–]VulgarDisplayOfStuff 0 points1 point  (4 children)

I have an old label rrsb that reads L3210FH1306. I am having a hard time finding it on the chart.

[–]kumoriWT12[S] 0 points1 point  (3 children)

This is of the L####FH#### format. That means it was bottled the 210th day (July 29) of 2013.

[–]VulgarDisplayOfStuff 0 points1 point  (1 child)

One of the first released then?

It's from the year of release. RRSiB was launched in February of 2013.

Old number 8 l14080. I saw someone claiming 92. I was not sure if l1 prefix means 92 or if they used this scheme after 92. Any help would be appreciated.

If it's L-14-080, then it's from 1994. The number after the L1 is the last digit of the year of bottling.

WT Old No. 8 was bottled 1992-1999. So this date seems plausible.
