How to recognize GUCCI perfumes and OLD batch codes.

"Dating" Gucci perfumes can be a very, very difficult task due to extremely intricated story of House of Gucci during decades.
Therefore, similarly to what was done with Jean Patou perfumes (read here the marvellous story-interview), we received some help from signor Ernesto, an old employee at Gucci in Florence, now retired, who helped us to solve many controversial aspects.
Dating Gucci perfumes can make you fool, because you have to "decipher" same numbers during different periods. 
One of the most famous example is batchcode "0163": it could mean year 2003 (Wella-type batchcodes, you have to check the last number) or year 2010 (Procter&Gamble-type ones, you have to check the first number).... 
So, in an attempt to "date" all Gucci perfumes, we have to proceed in a rather unusual way: "period-by-period" and "scent-by-scent".
But, after all, as signor Ernesto said us: "...in many cases, you can rely on the clues on the boxes, i.e. addresses, distributors, labels, more than the batchcodes..."
Follow us in this long and a bit complicate road.

How to recognize JEAN PATOU fragrances and batch codes.

The ultimate guide to Jean Patou perfumes from vintage classics to modern creations, covering historical periods, boxes, bottles, labels, batch codes, and all the details you need to identify every Jean Patou fragrance.

" ....you asked me how to put a date on old Patou perfumes, 

and I'll teach you it.... 

but you shouldn't care about years and months, 

because I worked at Patou, and I can assure you: 

Jean Patou was the best. 

All bottles produced were pieces of Art.

Top quality, the best materials, and the best perfumes. 

Jean Patou was Art."

Introduction.

We never heard about a method for dating vintage Jean Patou perfumes. Actually it is quite a difficult task, because technicians used ingenious tricks to date perfumes (such as the "inverse" alphabet), so we have to thanks an old french-italian lady ("Signora Mimma", she is 83-years old now!), once employed at Patou, who revealed us the secrets of the batch-codes, and gave us a marvellous interview about "good old times" spent with Patou.
This (very) long article is divided in 4 parts:
- Batch codes revealed;
- Tutorial pics;
- Glimpses from an interview;
- Miscellaneous pics. 
Follow us and learn why "Patou is not about dresses and perfumes; Patou is about Art."

A letter from an ex-Guerlain employee

A very important number:
the Formula.

An introduction to Guerlain "reformulations", from vintage classics to modern creations, covering historical periods, boxes, bottles, batch codes, labels, and all the details you need to identify every Guerlain fragrance.

(UPDATE: this is the Part 1. 
You can find the Part 2 here , with more questions and answers about vintage fragrances)

Introduction

On October, 2017, I received this letter about "reformulations", via a common friend. It is incredibly interesting and deserves the publication. It could be of some interest for all Guerlain enthusiasts. Anyway, it's really intriguing.
Sincerely yours,
Laura Alessi 

(translated from french)

The "formula" number.

"Madame, 
I read the articles written by your group, about the reformulations occurred in many perfumes: since I worked at Guerlain for a few years, I could give my contribution and suggest you a little trick. You don't need to collect and examine samples, batch-by-batch, and smell many stripes to determine if a reformualation occurred. It's quite time-consuming and in most cases, not really useful.  
There is a faster and more effective way to determine if a reformulation occurred. As you should know, all cosmetics since year 2003-2004 have to indicate the "allergens list" on the box. 
Since then, all LVMH perfumes (Guerlain, Dior, etc...) indicate the allergens, in conjunction with a particular progressive number evidencing the formula of each product. So, you will read different numbers for aftershaves, eau de toilette, eau de parfum, parfum, etc. 
Each number = a "recipe". 
So,when a reformulation occurs, the "recipe" changes, and you will read a different number. 
Collecting several boxes through the years, you will read different numbers ...and consequently you can spot on the reformulations.
There is no reason to smell several samples to guess if a change happened or not: simply look at the number on the box.
At Guerlain, the biggest part of reformulations happened since 2007. Please note this doesn't mean the new formulations are worse or better than the older. We at Guerlain were very strict on quality, and we put every attention in reformulations, I can guarantee it to you. You couldn't even notice any difference. Simply, check out the Formula on the corner of the box, and you will notice all reformulations. 

Since the numbers are in progressive order, with some experience you will be able to obtain all the infos you want, simply reading the batch code (year of production) and the formula. and guessing the date/type of reformulation of your own bottle"
