  • A Day at Hennessy

    The first stop on a big trip to Cognac, France last week was Hennessy. I met up with my host Cyrille at the Hennessy office, one of the Hennessy buildings that dominates the waterfront on the Charente River in the small city of Cognac.

    First we talked a bit about sales. Hennessy sells the most of their youngest expression, the VS, totaling something like 80 percent of sales volume, and most of that is to the US. The US generally consumes most congnac at the VS level, whereas in Asian markets consumers in particular tend to drink VSOP and older expressions.

    Next we headed to the vineyards and distillery. Hennessy owns several hectares of vineyard along with some distilleries and even forests, but these don't make up very much of their total production. These facilities are partially for testing and experimentation.

    As with most cognac houses, Hennessy buys most of their eau de vie on the open market or through winegrowers with whom they have contracts. They avoid buying from the Bois Ordinaires and Bon Bois regions, concentrating on the four innermost growing regions for their purchases even in their VS and VSOP blends. Hennessy uses the typical Ugni Blanc and Folle Blanche grapes, and is encouraging their growers to look into Folignan as well.

    All in all, the Cognac region has 70,000 hectares of vines on about 6000 properties (6000 winegrowers) and Hennessy alone deals with about 2000 growers. There are about 120 professional distillers in cognac, which prepare the eau de vie for the 150 cognac houses.

    Hennessy doesn't own a barrel building cooperage, but instead one for barrel repair. That was our next stop. As barrels are always stored on their side with the bung hole facing up, even non-perfect staves can still be used for the bung stave. As is also common, Hennessy uses several sizes of barrels, larger ones for older cognacs as they have a smaller cognac-to-wood ratio.

    We traveled next back into town and across the Charente river by boat from the main Hennessy building are some of the aging warehouses. There they age eau de vie in batches labeled with the distillery or vineyard and the year. As the eau de vie evaporates out of casks, young ones destined for VS are topped up with water, while older ones are topped up with the liquid from one sacrificial barrel from the same batch.

    I then tasted through the line, along with some new-make spirit and some older unblended eau de vie. I learned that some eau de vies are identified right off the still as special and are not put into new barrels to add structure as they already have it, but are moved right to used ones for long aging. Thus at the point of distillation, much of the eau de vie is being selected as to whether it will sit in a barrel for two or twenty years.

    Hennessy is located in Cognac and is open for daily tours most of the year, or one can just visit the gift shop downstairs and the display of advertising from the last 100 years upstairs.

  • All About Cognac

    I went to Cognac last week to learn about cognac. I learned a lot.

    So what is cognac, anyway?

    Cognac is an aged brandy distilled from grapes in the Charente region of France.

    The Cognac region is separated into six delimited subregions based primarily on the makeup of the soil: Grande Champagne, Petite Champagne, Borderies, Fine Bois, Bons Bois, and Bois Ordinaires. The Grande and Petite Champagne regions have the most chalky soil.

    Planted in the region is mostly Ugni Blanc grapes, with others like Folle Blanche and Columbard sometimes also used to make cognac. These grape varieties make horrible table wine, but are good for distillation. They are high in acid and low in alcohol content at harvest. The flavors in this largely neutral grape are concentrated through distillation and are teased out over aging in oak barrels.

    Grapes grown in the Grande and Petite Champagne region are able to age a long time, while those from the outer regions need less time in wood to show their full and fruity potential. Thus many brands reserve their Grande and Petite Champagne-produced barrels for their longer-aged blends.

    First the grapes must be harvested in the fall, then fermented into wine and distilled. Most harvesting is mechanical. Fermentation is started with yeast recommended by the government. Distillation runs through the winter and must legally be finished by the end of March, though most are finished far sooner. Cognac must be twice distilled in pot stills limited in size to 25 hectoliters in usable volume.

    Most cognac is aged in oak from the French Limousin or Troncais forests, and purchased from the government-run forest agency. Most of the trees used for barrels are 100 years old. French oak is high in tannins that help spirits age longer and add structure to the mouthfeel of the finished product.

    The aging process is not as static as you might think. First, newly made spirit is added to newish (up to 3-5 years old) barrels as these contain the most tannins. Depending on the cognac house and the previous number of uses of the barrel, the spirit may sit in new barrels for just a couple months to more than a year. Then the spirit is moved to old barrels where the tannins in the wood have less effect, but the porousness of wood allows continued interaction with the outside world via oxidation and evaporation.

    Most all cognac is a blend of aged spirit (eau de vie) from many vineyards and many different vintages. It is the master blender's job to ensure consistency of a blended cognac product despite a big variation in the individual eau de vies that go into it.

    Cognac labeled VS must be a minimum of 2 years, VSOP has a 4 year minimum, and Napoleon and XO have a six year minimum though this is being raised to 10 years for XO in 2016 (most XO's on the market are already older than ten years and won't have to change). Cognacs may be single vintage bottlings (all eau de vie comes from a single year) and labeled on the bottle. They may not say an average or minimum age on the bottle (example: "ten years old") as they can with scotch whisky.

    Older blends are not just further aged versions of younger blends- they are usually separate products. For example, a brand may compose their VS product primarily of eau de vie from the Fine Bois, while for their XO products most will come from Grande Champagne. 

    Cognac production is rather interesting, in that most cognac houses are only blending and aging houses. They do not traditionally own their own vineyards or their own distilleries, and they don't even need to own the aging facilities. (In reality the brands I visited owned some vineyards and distilleries but nothing close to the amount for their full production. It seems most all houses age most of their own eau de vie rather than buy it already aged.)

    The "big four" cognac houses that make up around 75-80% of the world market are Hennessy, Martell, Courvoisier, and Remy Martin. There are many smaller houses, of course, and some of these own vineyards and distill, age, and blend on-site.

    In future blog posts, I'll talk about some brand specifics.
