Guide to Closure Type

The Society's wine buyers work very closely with our suppliers to determine how best to seal our wines. We list below those closures currently in use with a brief description of each.

Cork, agglomerate

A technical cork made up of the remnants from the production of natural corks which are ground down into particles and cleaned and then combined using a food-grade polyurethane glue. A cheaper closure which The Society's buyers discourage suppliers from using.

Cork, colmate

A technical cork made from cheaper-grade natural cork where the naturally occurring pores are filled with ground down cork particles and then the whole is sealed with a food-grade wax coating. Generally only used for wines with a short shelf-life.

Cork, Diam

Diam corks look like agglomerate corks but are far superior and are designed to put an end to cork taint and random oxidation. The production process chops cork into pieces and sorts the superior, highly elastic, suberin component from the less elastic lignin, which is discarded. It mixes the suberin with microscopic spheres of the same substance used for contact lenses, which fills the voids between the cork particles reducing porosity to air and increasing elasticity without introducing humidity. Finally the pieces are mixed with a glue and moulded under pressure. The mechanical properties of the cork are guaranteed for a certain minimum number of years depending on the grade of cork - for example Diam 2 is guaranteed for two years; Diam 3, 5 and 10 are also available.

Champagne cork

The Champagne cork is 90% agglomerate made from cork off-cuts which are ground down, cleaned, compressed and then glued together with two disks of good quality natural cork glued onto the end which protrudes into the bottle.

Natural cork

Natural corks harvested from the cork oak (Quercus suber) forests in Spain and Portugal have been the closure of choice for wine for the 300 years. The bark of the cork oak is stripped from mature trees every nine years. The planks are stored and then cleaned and graded before the corks are punched out of the wood. For wines destined for long-ageing, high-grade natural corks are still the closure of choice.

Cork, plastic

Cost-effective synthetic 'corks' made from food-grade plastic with a silicone coating (similar to that used on natural corks). Generally used for wines for short-term cellaring.

Glass stopper

A glass stopper with a plastic 'O' ring which acts as an interface between the top of the bottle and the stopper, held in place by a metal, tamper-proof seal. Relatively expensive as a closure and not widely used. Can be removed by hand.

Stopper cork (ie sherry)

A short natural or agglomerate cork with a plastic or wooden top to enable the stopper to be removed by hand. Traditionally used for whiskies, sherries, Madeira etc.

Screwcap

Aluminium alloy screwcaps made with an expanded polyethylene wadding for the lining. Screwcaps are also known as ROTEs (roll-on tamper evident) or by the brand name (Stelvin is a popular brand). Widely used in Australia and New Zealand and for wines for short-term cellaring. Becoming increasingly sophisticated in terms of allowing differing levels of permeability so mimicking the properties of natural cork offering winemakers more choice depending of the style of wine being made. There is still a lack of sound data regarding the performance of screwcaps for longer-term cellaring.

Twin top

This is an agglomerate cork with a disk of good-quality natural cork adhered to both ends. A reasonably priced, reliable alternative to natural cork.

Crown cap

This is the metal pilfer-proof cap usually used to seal beer bottles but also used in the production of Champagne and sparkling wine when wines are stored under crown cap before the dosage is added. A few producers use crown caps to seal wine bottles. Open with a standard bottle opener.

Jamie Goode has written an excellent book on the subject of closures for those wishing to find out more (Wine Bottle Closures, Flavour Press).

The Society includes the alcohol by volume percentage figure for each wine available online, in Lists and offers.

We always include the abv (alcohol by volume) in our wines online, in our Lists and in our offers. Members looking to choose wines with lower levels of alcohol can now search our range by level of alcohol.

It is generally accepted that over the last 20 years or so alcohol levels in wine have been increasing. There are many reasons why, including but not limited to the vast improvement in vineyard management techniques which have resulted in healthier, riper fruit being harvested. Alcohol is a by-product of the fermentation of sugars in the grapes and the best-quality wines are made from grapes that have reached physiological ripeness (colour, flavour and tannin), and this generally happens after sugar ripeness.

There are several techniques that can be used to reduce alcohol levels but currently most strip the flavour as well as the alcohol, and we don't buy wines made in this way.

Excellent-quality wine is at the heart of everything we do at The Wine Society and balance is the single most important feature of quality. The interaction of a wine's sugar, acidity, tannin, alcohol and flavour matter more than the actual level of alcohol. A well-made wine of 14.5%, for example, will taste more balanced than an inferior-quality wine with 10% alcohol. Furthermore, alcohol levels are only a guide to a wine's fullness: a 12.5% cabernet sauvignon may feel heavier and more full-bodied in the mouth than, say, a gamay of 13.5%. Our tasting notes should be able to give you an idea of the style and fullness of an individual wine.

We are committed to promoting the responsible enjoyment of wines and spirits by providing relevant information to our members that allows you to make your own informed choices.

An additional figure used on some labels (including all our Society and Exhibition wines) is the number of (UK) units of alcohol contained in that bottle. This is simply the alcohol by volume percentage multiplied by the content (so a 13% wine in a standard 75cl bottle will have 9.7 units ).

The Society's buyers provide recommended drink dates for all of our wines to help members decide the right time to pop the cork. As a general rule, most everyday white wines are best enjoyed within a year of purchase, and most everyday reds within two years. Certain fine wines, however, those with the right structure and balance, have the ability to evolve over time and gain complexity and finer nuances of flavour.

Ageing fine wines

Savouring the wonderfully complex and intense bouquet and flavour of a wine drank at its peak is undoubtedly one of life's greatest pleasures. As with people, the ageing process will vary from wine to wine. Over the years the wine's primary aromas of fresh fruit will develop more complicated and persistent secondary and tertiary aromas. The fruity flavours of, for example, a premier cru white Burgundy will, over time, evolve buttery, toasty and yeast aromas, or fine reds may develop coffee, cedar, tobacco, vegetal, or even 'animal' flavours as they age.

When should wines with long drinking windows be opened?

There is much pleasure to be had by experimenting with bottles at different stages of maturity; finding out how a wine evolves with age and, perhaps more importantly, establishing your own preference in terms of taste for mature wine are all part of the interest and excitement of cellaring wine.

The drinking window we provide is a guide to when the wines will be at their best. Many will favour the wines in the youthful early stages of their development; others will enjoy the wines at their most mature.

Decanting is a useful way of softening the tannins, rounding out the flavours and releasing the potential of a young wine. To find out more please visit our Serving Wine guide.

Storing your wines with The Society

The Society's purpose-built, temperature-controlled Members' Reserves offers members access to optimum storage conditions for their wines.

Oak In Wine

Oak plays a very important role in the production of wine throughout the world. However, the level of oak detectible in a wine can vary depending on a number of factors – for example, the age and size of the barrel and the type of oak used, as well as the length of time the wine is aged in wood. Oak also influences the structure and tannins of the final wine. For wines on our website, we use the following classifications:

The influence of oak age and barrel size:

How detectable oak is depends a good deal on the size of the barrel and how new it is. New oak provides a much more evident flavour and aroma and must be used carefully. The size of the barrel is important, as the smaller the barrel, the more surface area of the wine is in contact with the wood and the more flavour will be drawn out. Often, very large old oak barrels are used, which impart little or no oak flavour to the wine at all. They will still bring an extra dynamic to the final taste of a wine though, when compared to stainless steel or concrete vessels, as oak is porous and therefore lets a small amount of air into the barrel. This controlled oxidation has a positive effect on wines, softening the tannins and developing secondary flavours, all helping to add a complexity which comes with age.

There are many ways that people rate wines, whether it is on the 100 or 20 point scales, 5 stars, 3 glasses or simply thumbs up or down. The pleasure of a bottle of wine is hard to express in figures, but it does help give the memory of that wine a context, and a way of sharing your opinion with others.

In response to members' requests we have added a star rating option to the site so you can mark your favourites, or maybe those occasional less-than-welcome experiences, and make your next order easier.

You can use the 5-star rating tool to record your experiences however you wish, but if you are looking for some guidance we believe that a focus on the 'value' of the wine takes into account the quality but also the pleasure it provided, and whether it is something you would recommend to friends.
