Clos of Champagne

Definition: Clos, from the French for closure or enclosed, is a walled vineyard used to protect the grapes from theft as well as improving the mesoclimate. They are often founded by Cistercian monks and the word is often used in the name of famous wines even when the wall no longer exists.

I have been trawling through books and the internet trying to find the exact number of clos in the Champagne region, but haven't had much luck getting an answer. I could find around 16 but I'm sure there must be more. However many there are, they certainly only account for a tiny fraction of the 80,000 hectares of vines there are in the region. I'm only going to go through a few of the famous ones otherwise this could turn into an essay.

There is much debate as to how much difference having a wall around your vineyard actually makes, but it's hard to argue against the fact that walls protect against a number of evils. There are two vineyards in the whole region which have managed to survive the root-chomping phylloxera louse epidemic in the early 20th century. One is Clos St-Jacques and the other is Clos des Chaudes, both of which are under Bollinger's ownership. There is no doubt that they have managed to survive partly due to their high surrounding walls. It is the vines from these vineyards which make the fabled Vielle Vignes Francaises super-prestige cuvee which commands prices starting at £300 a bottle.

These walls also protect the vines from the cold winds which are also common in Champagne. Krug's 1.85 hectare site, Clos du Mesnil in Mesnil-sur-Oger, also benefits from actually being wrapped in the warm blanket of the town itself. The clos' ideal South-East facing aspect and chalky soils help to make an extremely fine champagne of great purity and elegance. Krug released its 1995 Clos d'Ambonnay in 2008 and as if Clos des Mesnil wasn't pricey or exclusive enough, Clos d'Ambonnay is only 0.685 hectares with only c.3000 bottles of the 1995 produced at the astronomical release price of £1,450 a pop.

For me, one of Champagne's most interesting clos' is not actually a clos at all. Phillipponnat's premier cru site, Clos des Goisses in Mareuil-sur-Ay, only has a wall on the bottom edge of the vineyard. But lets not be picky; Clos des Goisses is an incredible vineyard and well worth a trip to see if you are ever in the region. It is on a steep, south-facing slope and has an average temperature around 1.5 degrees warmer than the average temperature in champagne. This means this clos can make wines of superior ripeness, even in miserable years like 2001. Tom Stevenson wrote a great article on this amazing vineyard.

Another lesser known, but equally beguiling clos from Mareuil-sur-Ay, is Billecart-Salmon's Le Clos St-Hilaire. At around one hectare this vineyard can only make between 3,500 and 7,500 bottles of champagne every year and is only made in exceptional vintages. Clos St-Hilaire is situated right next to Billecart-Salmons grande maison and is named after the patron saint of the village it lies in. Only Pinot Noir is planted here and the Blanc de Noirs produced are bold and powerful with great ageing potential, not unlike Bollinger's Vielle Vignes Francaises.

The final clos I want to talk about is the only clos actually within the city of Reims. It is owned by Lanson and is very originally named Clos Lanson. It is a single hectare site which was bought by Lanson in 1976. The Chardonnay grown in this vineyard has been used as a component in both Lanson's Black Label and Gold Label champagnes for years, but next year (2012) will see its birth as a single vineyard cuvee. I have no doubt that there will be a big marketing campaign letting everyone know how exclusive and rare this champagne is and I'm sure it will have a price to match its rarity. I am particularly looking forward to hearing more about it.

I hope you find these incredible vineyards as interesting as I do and hope you get a chance to try a couple of them. You may have to re-mortgage your house first though.

To Decant or not to Decant?

For most people, even many champagne aficionados, the thought of decanting a champagne before they serve it would not even even cross their mind. Surely it will cause your prized champagne to lose all of its bubbles, wouldn't it? However, it is an interesting practice which seems to be gathering momentum recently, especially with the sommeliers in Paris. It's not as mad as you may think though, after all, it is a fine wine and you wouldn't dream of opening your favourite Bordeaux or Burgundy without allowing it to 'breathe' for an hour or two. Furthermore, the act of decanting doesn't actually cause a champagne to lose its bubbles as fast as you may think. Experts have worked out that a champagne will only lose 10-15% of its effervescence through the act of decanting. A word of warning though, you must take care when decanting your champagne, imagine you are trying to pour the perfect pint!

So, what can you actually gain from decanting a champagne? Like, with other wines, decanting champagne allows aromas in the wine to be released. This causes the champagne to become more fragrant and it can also dramatically change how your champagne tastes. Something which seems fresh and citrussy upon opening can give way to rich, earthy and all together more vinous flavours after just 10 minutes in a decanter (or even just left in a glass).

Charles Heidseick, one of my favourites of the big champagne houses, is a big advocate of decanting their champagnes. They have even teamed up with Riedel, the glassware giant, to produce a very elegant decanter. Billecart Salmon have also produced a limited edition decanter which some Searcys champagne bars in London will be using.

Decanting champagne is definitely worth a try. A fun experiment to try which I saw Jennifer Simonetti-Bryan , MV do on Wine Library TV is to open a bottle of champagne and decant half the bottle and leave to rest in the bottle with a champagne stopper in. Leave both for around 30 minutes and then do a side-by-side comparison. The differences between each samples are noticeable and dramatic.

Brut Zero Champagne

'Brut Nature' or 'Brut Zero' champagnes certainly seem to be on the up at the moment. Many of champagnes largest houses are releasing Brut Zero champagnes in a bid to keep up with changing tastes. Consumer palates, especially in the UK, seem to moving towards a drier style of champagne. Even the worlds most popular champagne, Moets Brut Imperial, is to lower its sugar levels from 12 g/l to 9 g/l in a move to keeps it crown.

'Brut Nature' or 'Brut Zero' champagnes contain less than 3 grams of residual sugar per litre, as opposed to the 6-15 grams typical in most Brut style champagnes and, if made correctly, can show great purity and expression of fruit but if made badly, they can be incredibly austere and thin. The champagne houses tend to use riper vintages as a base to the blend so these blends can be naturally balanced without the need for the sweet dosage. This style of champagne is not, however, necessarily a new concept. Many champagne houses use much lower dosages in their prestige cuvees. The addition of a dosage is often described as 'make up' for the champagne, so the better the champagne, in theory, the less dosage it needs to hide it flaws. This means Brut Nature champagnes can be some of the most candid, frank expressions of terroir and house style that there are.

So, what do Brut Zero champagnes bring to the table that Brut champagnes can't? For a start they are some of the least calorific wines you can buy. Brut nature champagnes have around 65 calories per 125ml glass which is all very well but they are much more than just a diet option.  They are, also, incredibly food friendly because their high acidity levels make them a great palate cleanser. They work well with delicate foods like sushi, scallops and simply cooked fish and also work fantastically with fatty foods such as caviar and foie gras beacue the acidity cut through the fat.

Here are some of the best Brut Nature or Brut Zero champagnes I have tasted recently:

Perle d'Ayala Nature Brut 2002 - 20% Pinot Noir, 80% Chardonnay. This champagne is made from grapes from only Grand Cru and Premiers Cru villages. All the wines have been left on their lees for five years which helps to give them an aromatic nose and complex palate. This champagne has subtle red fruit along with a chalky minerality, candied lemons and a pleasant smokiness. £79.95 from Champagne Direct

Billecart-Salmon Extra Brut NV - 40% Pinot Meunier, 35% Pinot Noir, 25% Chardonnay. Released last July this is one of the new kids on the block. It is made in a very similar way to its esteemed sibling, the Brut Reserve but is left on its lees for slightly longer to allow all its components to mingle. It has a wonderfully floral nose and a soft palate full of brioche and dried fruits and a slightly smokey character.  £38.85 from Berry Brothers and Rudd

Laurant Perrier Ultra Brut NV - 55% Chardonnay, 45% Pinot Noir. This is only made in very ripe years with high natural levels of sugar and the componant wines are selected from parcels which have an average of 97% on the echelle des crus. This champagne has a fine bead and a light palate with preserved lemons and a slightly saline minerality. It is a perfect match for super fresh oysters. £38 from The Champagne Company

Tarlant Zero NV - 33% Pinot Noir, 33% Chardonnay, 33% Pinot Meunier. This Oeuilly based house is a huge believer in the low dosage style and this is their flagship champagne. It is lean and focused with a razor-like citrus hit and crushed shells. I think this will appeal to Chablis Drinkers £27 from Marks and Spencer
