Moët & Chandon: blending across vintages and single-harvest wines
This is a Champagne house based in Épernay. They produce Moët Impérial, a blend of multiple vintages, and Grand Vintage, which displays the harvest year.
We will explain the differences between Imperial and Grand Vintage without confusing the number of grape varieties and the number of harvest years.
Questions for this course
Even for wines without a vintage indication, is there a selection of years?
Before you start reading, briefly jot down your thoughts. You will rephrase them at the end.

Imperial base wine
Moët Impérial is made by blending a large number of base wines, of which 20–30% are described as reserve wine. Reserves are base wines kept from previous harvests; the absence of a vintage year on the bottle does not mean that vintages have not been selectively blended.
Single vintage Grand Vintage.
Grand Vintage is introduced as a different wine for each harvest year, such as 2013, 2015, or 2016. This allows you to compare decisions to continue a house style with decisions that reflect a single year's crop.
Make variety and year two axes.
Imperial is made with Pinot Noir, Meunier, and Chardonnay. The axis of grape variety and the axis of vintages used as reserve wine are separate. You cannot determine that multiple vintages are used just because there are multiple varieties.

Interpreting Moët & Chandon documents: blending across vintages and single-vintage production
Compare the stated conditions in the documentation. Numbers specifying vintages should be treated as information for that specific year.
This summarizes materials published by producers, regional groups, and importers. Each source includes the publisher and the date the material was checked.
| Comparison items | What can be determined from the materials | Ability to distinguish by reading |
|---|---|---|
| Imperial | Explanation: 20–30% reserve wine | Includes base wine from previous harvests |
| Grand Vintage | Brands for each vintage year | Even in a single vintage, the base wines are combined. |
| Grapes | Pinot Noir, Meunier, Chardonnay | Distinguish between number of grape varieties and years |

What is reserve wine?
This indicates the vintage of the base wine.
Which year is the Grand Vintage?
This is a label that shows the raw materials by vintage.
Does using several grape varieties always mean several vintages?
We will consider two types of blends separately. The classification "Pinot Noir, Meunier, Chardonnay" refers to the varieties used. In contrast, "Réserve" refers to base wines preserved from previous harvests. Even if three grape varieties are used, it does not necessarily mean that three vintages are included.

Explain in your own words
When explaining the differences between Imperial and Grand Vintage, do not confuse the number of grape varieties with the number of harvest years.
Check after writing
- Did you specify the label, vintage, and scope of materials to be compared?
- Did you distinguish and explain the three items in the table?
- Did you separate verified facts from points to check further with additional references or tasting?
