Query: What makes an ice wine an ice wine?
Ice wine was first produced in Michigan in 1983 by Mark Johnson, who at the time was working at Chateau Grand Traverse and is currently the head winemaker at Chateau Chantal. Northern Michigan wineries follow some of the German practices that govern what wine qualifies as ice wine. German law dictates that ice wine must be picked only when the grapes are frozen on the vine, while United States law allows for wine to be sold as ice wine if the grapes are picked and then artificially frozen. Because of the impossibility of predicting nature, making ice wine requires a great deal of luck. The grapes are generally picked in December after prolonged below-freezing temperatures, to ensure they are frozen all the way through. But in warmer years the grapes cannot be picked until late into January. It can also be difficult to protect the grapes from birds and wind as they stay on the vine until after they are very ripe.
Sherry is then aged in the solera system where new wine is put into wine barrels at the beginning of a series of three to nine barrels. Periodically, a portion of the wine in a barrel is moved into the next barrel down, using tools called the "canoa" (canoe) and "rociador" (sprinkler) to move the wine gently and avoid damaging the layer of flor in each barrel. At the end of the series only a portion of the final barrel is bottled and sold. Depending on the type of wine, the portion moved may be between five and thirty percent of each barrel. This process is called "running the scales" because each barrel in the series is called a scale. Thus, the age of the youngest wine going in the bottle is determined by the number of barrels in the series, and every bottle also contains some much older wine than is stated. Sherry is aged in the solera for a minimum of two years. A large solera system may consist of scales that require more than one barrel to hold. The word 'solera' means 'on the ground'; this refers to the stacking system that was, and sometimes still is, used, with the youngest barrels at the top and the oldest scale, also somewhat ambiguously called 'the solera', at the bottom. Of late, Sherry producers and marketers have been bottling their wines "en rama", with only a light filtration, and often a selection of a favored barrel from a larger solera. Such sherries can be considerably more complex in flavour than the standard bottlings, and, according to many, are worth seeking out. In order to allow the sale of reliable average age-dated sherries, the regulating council has set up a system that accurately tracks the average age of the wines as they move through their solera. Two average age-dated categories are recognized: VOS ('Vinum Optimum Signatum' – 20 years old average age minimum) and VORS ('Vinum Optimum Rare Signatum' – 30 years old average age minimum).
On its own, Gros Manseng has the potential to produce intensely flavored wines with high acidity, apricot and quince fruit along with spicy and floral notes. The time of harvest will play a large role in the type of wine that the grape will produce. When it is picked at a potential alcohol level of 11.5-12%, the resulting wine will have more characteristics of fresh fruit and flowers. If picked later at a potential alcohol content of 12.5-13.5, the flavors will be much more intense and powerful. Despite its thick skin, the grape does need gentle handling in the winemaking process. Unlike many wine grapes, the juice of the Gros Manseng is "grey" in color which means that it is already prone to produce deeply, golden colored wines with minimal skin contact. If the grapes are pressed too roughly or the grapes are left in extended contact with the skins, the resulting wine will be very coarse with excessive levels of tannins and polyphenols. Some winemakers are experimenting with making botrytized wine aged in oak that have drawn favorable comparisons to similarly made wine from Sémillon. That style wine is prized for its food matching ability, particularly with foie gras.
Wine barrels, especially those made of oak, have long been used as containers in which wine is aged. Aging in oak typically imparts desirable vanilla, butter and spice flavors to wine. The size of the barrel plays a large role in determining the effects of oak on the wine by dictating the ratio of surface area to volume of wine with smaller containers having a larger impact. The most common barrels are the Bordeaux barriques style which hold followed by the Burgundy style barrel which hold . Some New World wine makers are now also using the larger hogshead barrel. Larger barrels are also traditionally used in parts of Italy such as Barolo, as well as the south of France.
Oak is used in winemaking to vary the color, flavor, tannin profile and texture of wine. It can be introduced in the form of a barrel during the fermentation or aging periods, or as free-floating chips or staves added to wine fermented in a vessel like stainless steel. Oak barrels can impart other qualities to wine through evaporation and low level exposure to oxygen.
Cider or cyder ( ) is a fermented alcoholic drink made from any fruit juice; apple juice (traditional and most common), peaches, pears ("Perry" cider) or other fruit. Cider alcohol content varies from 1.2% ABV to 8.5% or more in traditional English ciders. In some regions, cider may be called "apple wine".
Most red wine is aged for some period before bottling, though this can vary from a few days, in the case of Beaujolais Nouveau to 18 months or more in the case of top Bordeaux reds. Aging can take place in stainless-steel or concrete tanks, or in small or large oak barrels. The latter impart some flavour to the wine as a function of their age and size (small, new barrels give more flavour than large, older barrels).
– cider is a fermented alcoholic drink made from apple juice. Cider alcohol content varies from 1.2% ABV to 8.5% or more in traditional English ciders. In some regions, cider may be called "apple wine".
The drink is prepared by mixing the fruit and the sugar together, and adding the liquor. This can be made into a single glass, usually large, that can be shared amongst people, or into a larger jar, from which it is served in individual glasses.
After fermentation the grapes are then aged in small oak barrels. In many DOC regions, the wines are required to age for at least 3 years though it is not uncommon for producers to age their wines for 5 to 10 years. Traditionally the barrels were made of chestnut instead of oak, which contributed high amounts of wood tannins and was very porous which promoted excessive evaporation in the barrel. Under this same traditional style of winemaking, a large ullage or air space would emerge in the barrel and oxidation took place. This gave the wine its characteristic amber but also flavours and traits that may be characterised as wine faults. Towards the end of the 20th century, more produces began switching to oak barrels while maintaining the tradition of not topping up the barrels and filling in the ullage space. This angel's share still produces some level of oxidation, though not as severe as the style was historically made. Modern winemaking technique also calls for more temperature control and keeping the wine in rooms with a consistent temperature that promotes more fresh flavours in the wine and fewer faults.
Most of the Champagne produced today is "Non-vintage", meaning that it is a blended product of grapes from multiple vintages. Most of the base will be from a single year vintage with producers blending anywhere from 10–15% (even as high as 40%) of wine from older vintages. If the conditions of a particular vintage are favourable, some producers will make a vintage wine that must be composed of 100% of the grapes from that vintage year. Under Champagne wine regulations, houses that make both vintage and non-vintage wines are allowed to use no more than 80% of the total vintage's harvest for the production of vintage Champagne. This allows at least 20% of the harvest from each vintage to be reserved for use in non-vintage Champagne. This ensures a consistent style that consumers can expect from non-vintage Champagne that does not alter too radically depending on the quality of the vintage. In less than ideal vintages, some producers will produce a wine from only that single vintage and still label it as non-vintage rather than as "vintage" since the wine will be of lesser quality and the producers have little desire to reserve the wine for future blending.
The juice of any variety of apple can be used to make cider, but cider apples are best. The addition of sugar or extra fruit before a second fermentation increases the ethanol content of the resulting beverage. Cider alcohol content varies from 1.2% to 8.5% ABV or more in traditional English ciders, and 3.5% to 12% in continental ciders. In UK law, it must contain at least 35% apple juice (fresh or from concentrate), although CAMRA (the Campaign for Real Ale) says that "real cider" must be at least 90% fresh apple juice. In the US, there is a 50% minimum. In France, cider must be made solely from apples.
Exports of Bulgarian wine go worldwide; and until 1990 the country exported the world's second-largest total of bottled wine. The rich soil, perfect climate and the millennia-old tradition of wine-making, which dates back to the time of the Thracians, contribute to the wide variety of fine Bulgarian wines. As of 2007, Bulgaria produced 200,000 tonnes of wine annually, ranking 20th in the world.
Fermentation of ciders occurs by a very similar mechanism to the fermentation of wine. The process of alcoholic fermentation is characterized by the conversion of simple sugars into ethanol by yeasts, especially "Saccharomyces cerevisiae". This is because, as “Crabtree positive” yeasts, they produce ethanol even during aerobic fermentation; in contrast, Crabtree-negative yeasts produce only biomass and carbon dioxide. This adaptation allows them a competitive edge in the fermentation of ciders due to their high alcohol tolerance, and because of this tolerance, it is common for ciders to be fermented to dryness, although that is not always the case. Fermentations will carry on until the yeasts run out of nutrients and can no longer metabolize, resulting in a "stuck" fermentation, or the fermentation is stopped.
After fermentation, the oak barrel aging regiment will vary with the length of time and proportion of new oak barrels that are used. Most Cote de Nuit producers prefer to age their red wines for at least a year to 18 months and blend lots between barrels of different ages. The traditional barrel used in Burgundy holds 228 liters which is slightly larger than the 225 liters that a traditional Bordeaux wine barrel holds. Prior to bottling, the producer will decide on what, if any fining and filtration methods will be used in the clarification and stabilization of the wine. Some producers will use both, others will fine and not filter and a few will choose to use neither, believing that they can reduce the complexity of the wine even though the wine may have a higher risk of spoilage and instability.
Cider ( ) is an alcoholic beverage made from the fermented juice of apples. Cider is popular in the United Kingdom, especially in the West Country, and widely available. The UK has the world's highest per capita consumption, as well as its largest cider-producing companies. Cider is also popular in many Commonwealth countries, such as India, Canada, Australia, and New Zealand. Aside from the UK and its former colonies, cider is popular in other European countries including Ireland, Portugal (mainly in Minho and Madeira), France (particularly Brittany and Normandy), northern Italy (Piedmont and Friuli), and Spain (especially Asturias and the Basque Country). Central Europe also has its own types of cider with Rhineland-Palatinate and Hesse producing a particularly tart version known as Apfelwein. In the U.S. and parts of Canada, varieties of fermented cider are often called "hard cider" to distinguish alcoholic cider from non-alcoholic "cider" or "sweet cider", also made from apples.
An "aging barrel" is used to age wine; distilled spirits such as whiskey, brandy, or rum; beer; tabasco sauce; or (in smaller sizes) traditional balsamic vinegar. When a wine or spirit ages in a barrel, small amounts of oxygen are introduced as the barrel lets some air in (compare to microoxygenation where oxygen is deliberately added). Oxygen enters a barrel when water or alcohol is lost due to evaporation, a portion known as the "angels' share". In an environment with 100% relative humidity, very little water evaporates and so most of the loss is alcohol, a useful trick if one has a wine with very high proof. Most beverages are topped up from other barrels to prevent significant oxidation, although others such as vin jaune and sherry are not.
No specific Basque legislation exists surrounding cider but there is national Spanish legislation which states defines natural cider as "la sidra elaborada siguiendo las prácticas tradicionales, sin adición de azúcares, que contiene gas carbónico de origen endógeno exclusivamente. Su graduación alcohólica adquirida será superior a 4'5 grados" "cider produced following traditional methods without the addition of sugars, containing only endeogenous carbon gas. The alcohol content must exceed 4.5%". The other relevant pieces of legislation are Law 25/1970 and Decree 835/1972 which regulate address issues connected to the chemical composition of cider and cider production such as maximum sugar content, rules on production and prohibited methods (such as adding wine or alcohol).
In Bordeaux, most serious wines undergo barrel-ageing, although white wines can be an exception. Usually, six months of ageing in-barrel is required, but some châteaux barrel-age for as much as 20 months. The number of new barrels (which impart a higher degree of oak flavor to the wine) can vary from vintage to vintage, just as the duration of barrel-ageing. Only recently, addition of oak chips has been made legal in Bordeaux. During barrel-ageing, the wine needs to be racked in order to clear it of lees. This process is being challenged by some producers, as mentioned abovem since ageing on the lees can also add richness to the wine.
Philippine wine or Filipino wine is wine produced in the Philippines. Most of the wines produced in the country are based on locally produced crops such as mangoes and rice with grape-based wines mostly imported from Australia and European countries. In 2012, it was reported that previous attempts to produce grapes which are suitable enough for wine making in northern Philippines failed due to unsuitable soil conditions and high temperatures.
The cider is ready to drink after a three-month fermentation period, although it is more often matured in the vats for up to three years.
Typical grapes used for ice wine production are Riesling, considered to be the noblest variety by German winemakers; Vidal, highly popular in Ontario, Canada; and the red grape Cabernet Franc. Many vintners, especially from the New World, are experimenting with making ice wine from other varieties: whites such as Seyval blanc, Chardonnay, Kerner, Gewürztraminer, Chenin blanc, Pinot blanc, and Ehrenfelser; or reds such as Merlot, Pinot noir, and even Cabernet Sauvignon. Pillitteri Estates Winery from the Niagara-on-the-Lake region of Ontario claim to be the first winery in the world producing Shiraz (Syrah) ice wine with the 2004 vintage, Semillion, and Sangiovese in 2007.
The most famous (and expensive) ice wines are German "Eiswein", but ice wine is also made in European countries such as Austria, Croatia, Czech Republic, Denmark, Georgia, France, Hungary, Italy, Lithuania Luxembourg, Poland, Romania, Moldova, Slovakia, Slovenia, Spain, Sweden and Switzerland at least in smaller quantity. "Eiswein" is part of the "Prädikatswein" quality category in the German wine classification. The French language term "Vin de glace" is part of the wine classification in Luxembourg, but not in France, but is sometimes found on the rare bottles of ice wine produced in Alsace. In most of France, the climate is too warm for ice wine production.
Ice wine usually has a slightly lower alcohol content than regular table wine. Some Riesling ice wines from Germany have an alcohol content as low as 6%. Ice wines produced in Canada usually have higher alcohol content, between 8 and 13 percent. In most years, ice wines from Canada generally have higher brix degree (must weight) compared to those from Germany. This is largely due to the more consistent winters in Canada. Must with insufficient brix level cannot be made into ice wine, and is thus often sold as "special select late harvest" or "select late harvest" at a fraction of the price that true ice wine commands.
Though Pelee Island Winery and Hillebrand were Canada's first commercial ice wine producers, starting production in 1983, Inniskillin Wines is considered the most widely known Canadian ice wine producer as the first Canadian winery to win a major international award, the Grand Prix d’Honneur at 1991 Vinexpo in France, with their 1989 Vidal Icewine (which was technically an illegal import into the EU), placing Canadian ice wines on the world stage. Pillitteri Estates Winery has emerged in the 2000s as the world’s largest estate ice wine producer. In November 2006 the Canadian producer Royal DeMaria released five cases of Chardonnay ice wine with a half-bottle price set at C$ 30,000, making it the world's most expensively priced wine.
