The different types of champagne

The type of champagne is determined by the amount of sugar that each contains. Depending on that we have from the least sweet to the sweetest: 'extra-brut', 'brut', 'extra-dry', dry, semi-dry, sweet.Another type of classification is depending on the vintage - the year of harvest or the type of grapes used, without using white grapes Chardonnay is called Blanc de blancs and if the grapes used are Pinot Meunier and Pinot Noir It is known as Blanc de noirs or Rosé.

Non vintage

85% of the champagne we drink is non vintage. This means that it may contain champagne with different age. The minimum aging in the cellar is 15 months.


All the wine in this champagne is from the same year. Minimum aging is 36 months.

Blanc de noir

It is made from Champagne’s black grape grapes-

Pinot Noir

or pinot Meunier or a blend of both. It can be NV or Vintage.


Pink champagne is generally made by blending red and white wine. Champagne is the only place in the world where this is allowed. Can be NV or Vintage

Owning champagne - what to remember?

The correct preservation of champagne will allow it to preserve its properties and its original flavor. Here are some suggestions.

Bottle position

The position of the bottle at rest is essential, and that is why they must be lying down so that the cork, in contact with the wine, prevents any exchange with the outside. In this way we will avoid that the plug loses elasticity and facilitates gas leaks, as well as aromas, which would occur if the bottle were standing.

Exposure to light

Champagne should be protected from light, avoiding exposure to sunlight because otherwise it would deteriorate rapidly. To be aware of this, it is worth noting that with a powerful light, only 78 hours are enough for the liquid to lose its original properties.Only the light from the sodium lamps produces no degradation.


As for the temperature, the bottles should not undergo changes trying to keep them in a cool place.It is important to take these aspects into account, especially when you do not have a cellar that is well adapted to the ideal standards.Champagne should cool slowly. To reach the right temperature to consume, the best method is to submerge the bottle in a bucket with a mixture of water and ice for 20 minutes or half an hour.In case of not having these elements, you can cool down in the refrigerator but keeping in mind that it should not be left for a long time, no more than half a day, because otherwise the champagne loses carbonic properties.The ideal temperature to serve is 6º to 8º C. Always try not to serve too cold or icy because it loses all flavor; and if it is excessively hot it becomes heavy, loses the aroma and the foam disappears.

How to start collecting champagne?

Many would love to have their own collection of champagne’s, but few decide to take the step, because it requires a certain knowledge about what bottles to buy. There are indispensable things to make this dream a reality without being an expert on the subject

.1) High income

Only buy high value champagne if you have the necessary financial situation. It is expensive and require storage, insurance etc.

2) Track your collection

Make sure you know exactly what you have and the value. Make sure to get an online appraisal if you are in doubt or check databases.

3) Have a decent storage

Champagne needs a delicate storage and handling. Especially if you buy high valuable bottles - this is an important part of collecting champagne.

4) First value matters

What is valuable today will likely be worth more tomorrow.

5) Documentation

Keep everything - receipts, auction estimates, appraisals etc. At some point provenance is important and here it matters where and when you bought it.

6) Have your champagne collection appraised

Markets can be extremely volatile, so make sure you know the value of your collection. You can get appraisals online on champagne here.

7) Let them sleep

Dont move them frequently or take it from the cellar every weekend to show your friends.

8) Buy what you like

There are plenty of producers with excellent taste. Buy what you like and don´t just follow the trends.

9) Start small

The fun thing about building a collection is to follow and see the growth. Dont just buy everything at once. Hunt the good deals.
