Grape vines are known to be hardy crops, with wine varieties being grown anywhere from the cold bracing countryside of Canada, to the sands of the Gobi desert. But news this week from an interview with a Nasa scientist has people wondering whether a sand dune really is really the most exotic place to produce grape varietals for wine-making. Any vine would have to be extremely cramped, due to limited space availability on the ISS, meaning it would be tricky to ensure the plant received enough light to grow properly. You might have to inoculate with the right types of microorganisms but I think it would definitely be possible.

VIDEO ON THE TOPIC: How to Make Wine from Grapes - MAKING OF WINE - ND WINES

Alcohol reduction of wine has gained significance worldwide. There are several technologies available to reduce the alcohol content in a targeted way.

This chapter explains the principles of alcohol reduction by physical methods. Different membrane processes such as osmotic distillation and the two-step dealcoholization process of reverse osmosis combined with osmotic distillation are compared with distillation processes such as vacuum rectification and spinning cone column.

An alternative approach the membrane coupling of ultra- and nanofiltration is described as well. All those technologies appear more or less suitable to reduce the alcohol content in a targeted way. Nevertheless improper handling can cause severe quality losses for the wine. Therefore, enologists should have a thorough understanding of the technologies to avoid negative impact on wine quality through the treatment. Advances in Grape and Wine Biotechnology. Studies from several countries show rising alcohol contents for wine over the last decades.

There are many factors contributing to that phenomenon. Better viticultural practices and improved plant material lead to elevated sugar levels in grapes. In higher alcohol yields of selected yeast strains, modern vinification techniques furthermore lead to an increase in alcohol.

The other driving factor for that development is the climate change which cannot be turned back that easily as the other factors. Additionally, enologists run into fermentation problem caused by elevated sugar contents of grape must and excessive alcohol contents at the end of fermentation.

Especially the production of sparkling wine requires moderate alcohol contents to avoid problems with second fermentation. As a result alcohol management has taken a new direction, from mainly maximizing alcohol contents to minimizing alcohol levels, as well.

There are several physical methods available for reducing the alcohol content to a targeted level. They are either based on membrane processes such as osmotic distillation and reverse osmosis coupled with another treatment or on distillation under vacuum.

The physical methods for alcohol reduction allow a targeted optimization of the alcohol content according to marked demand or to adapt to taxation and import tariffs based on actual alcohol content of the wine. There are several strategies available to produce wine with less alcohol. The most interventions take place before the wine status either in the vineyard, prior, or during fermentation Table 1.

Overview of strategies to achieve wines with lower alcohol content [ 57 ]. The strategies based on grapevine breeding and selection of clones as well as all strategies in viticulture are preventative and require a certain plan in advance. If, contrary to the assumption, the weather conditions for grape ripeness are very unfavorable, the desired maturity delay or reduced sugar storage in the berry is counterproductive.

In the field of microbiology, two different approaches are possible to produce less alcohol from the initial sugar present. One possible way is to reduce the sugar content before fermentation by using the enzyme glucose oxidase. The glucose present in the must is converted to gluconic acid in the presence of molecular oxygen by the enzyme glucose oxidase GOX. The challenge with this process is to reduce the oxidation of other constituents of the must and to reduce excessive acidity in wine [ 50 , 53 ].

Another microbiological strategy is the use of special yeasts with lower alcohol yield. These yeasts usually show a higher content of fermentation by-products. Due to these other metabolites, the quality as well as the typicality of the wines produced may suffer. The use of genetically modified yeasts is probably seen as very critical by most consumers [ 60 ]. Also the metabolism of yeast can be rearranged by taking advantage of the so-called Pasteur effect.

However, the control and addition of must has to be very precise in this process. Automatic measurement and control technology should help to facilitate this process for the user. Sugar reduction through membrane coupling can be seen as a unique technological approach for reducing elevated alcohol levels. Before problems arise due to excessive sugar levels in must, fermentation problems are prevented by a selective intervention. The sugar reduction of must is performed in two steps.

Subsequent treatment with ultrafiltration and nanofiltration removes sugar from the must. Consequently, the fermentation produces a wine with lower alcohol. This technology may help to prevent stuck and sluggish fermentations due to high sugar contents and consequently elevated alcohol levels.

These high alcohol levels also have a negative influence on malolactic fermentations [ 5 , 49 ]. First membranes for ultrafiltration were commercialized in by membrane filter GmbH [ 1 ]. The retained particles are usually 0. Common applications of ultrafiltration in food production are dairy processing in milk processing plants and clear filtration in fruit juice production.

The use of ultrafiltration for protein removal is conceivable in winemaking [ 22 , 23 , 29 , 62 ]. Nanofiltration was developed in the late s. It has been described as a technique between ultrafiltration and reverse osmosis.

Nanofiltration usually retains molecules such as sugars and organic acids. Nanofiltration has many possible applications in winemaking. It is used to remove volatile acidity or to reduce the amount of malic acid.

Nanofiltration is also used to concentrate must and wine. If nanofiltration is coupled with another process, the alcohol content of wine as well as the sugar content in the must can be reduced [ 11 , 16 , 17 , 19 , 26 , 40 , 44 , 57 ].

In this case the permeate of an ultrafiltration is separated in the first step. This fraction contains besides water, acid, and sugar only a few anthocyanins and tannins. During the second step, this fraction is concentrated by nanofiltration. The permeate of the nanofiltration contains then mainly water, some acids, and barely sugar. This aqueous solution is finally blended back to the retentate of the ultrafiltration.

The sugar content of the must is thereby reduced after the treatment. The byproduct of that process is the retentate of nanofiltration. This fraction is viscous and high in sugars. The ratio of fructose and glucose is maintained because nanofiltration withholds equal amounts of fructose and glucose. Tartaric acid and potassium are retained only to a small extent, whereby the acidity and pH value are not or hardly changed. Anthocyanins and polyphenols are concentrated in the retentate of nanofiltration due to their molecular size.

Consequently, they would be missing in the treated must. Therefore, it is important for red wine to perform the procedure before maceration. This fraction has to be clarified and treated by the two-step process to avoid color and tannin losses. This pre-clarified fraction is then reduced in sugar content and finally added to the original red wine mash [ 25 , 26 , 57 ].

The English-language literature contains various synonyms for osmotic distillation, such as membrane distillation, transmembrane distillation, capillary distillation, or pervaporation. Other sources also speak of isothermal membrane distillation [ 28 , 36 ]. In the process of osmotic distillation, two liquids are separated by a microporous, non-wettable membrane.

Both fluids are directed along this membrane, with none of the fluids permeating the membrane pores. Only the volatile components present in the respective liquids can pass the membrane by evaporating and permeating through the pores of the membrane. This gas phases then go into solution of the other side of the membrane. Due to the hydrophobic nature of the membrane, water cannot penetrate the pores of the membrane.

Thus, ions, colloids, and macromolecules that do not evaporate and diffuse through the membrane are completely retained. Osmotic distillation is an isothermal membrane process at atmospheric pressure.

The driving force for the molecule passage is the vapor pressure difference of a substance between the two sides of the membrane. The volatile components permeate from the membrane side with higher vapor pressure to the side with lower vapor pressure until equilibrium sets [ 12 , 13 ].

In osmotic distillation for the partial reduction of alcohol in wine, water is used as strip medium. Apart from possible losses of volatile aroma components, the ethanol flux is of considerable interest.

The flux is the amount of permeate that pass through the membrane per unit time. In osmotic distillation, it can be described as follows:. The ethanol flux is influenced by a number of factors. Higher feed and strip media speeds will increase the alcohol transfer through the membrane. Furthermore, the temperature has an influence.

As temperatures rise, the flux of volatile components increases. For the efficiency of osmotic distillation, it is important that both sides of the membrane are sufficiently hydrophobic. The pores should not get wet, and no water should penetrate the membrane by capillary action [ 36 , 64 ].

The gas and vapor passage through the membrane pores takes place by diffusion. Various references suggest that simultaneous water transfer takes place between both sides of the membrane. The higher the process temperature, the higher the water transfer is.

If the so-called stripping water is degassed before treatment in order to avoid an undesirable gas input into the wine, the water transfer is also increased. If the wine temperature is higher than the water temperature, the water transfer increases. If the membrane is damaged in its hydrophobic property by improper cleaning and storage, it can be assumed that the transfer of water increases.

The water vapor permeating the membrane is relatively more composed of light oxygen atoms. Even if relatively small amounts of water are released into the wine, the osmotic distillation for alcohol reduction could simulate significantly higher levels of water in the wine. The technique of osmotic distillation is widely used in various industries.

Winemaking or vinification is the production of wine , starting with the selection of the fruit, its fermentation into alcohol , and the bottling of the finished liquid. The history of wine -making stretches over millennia.

The event is the largest such exposition in North America, and it draws businesses from around the world exhibiting their wares, along with wine producers from all over the Western Hemisphere. They came, of course, for the networking opportunities, the chance to talk shop with their peers and all the rest of the socializing that goes with conventions of any kind. Attendees also came for seminars and discussions of grape-growing, winemaking, marketing and business analyses, and maybe even for the keynote speaker, who this year happened to be me. Mostly, they come for the hardware, exhibited by roughly companies and ranging from the mundane to the high-tech to the genetically manipulated.

Production guidelines for Australian table grape varieties

This note includes a description of the most commonly grown table grape varieties in Australia, and includes production guidelines. The production guidelines include techniques or problems specific to each variety and assume a good level of management, irrigation monitoring and a sound pest and disease control program. Table grapes adapt to a wide range of soil types. But on rich fertile soils, vines may produce excessive vigour and must be managed to produce sweet and well-coloured fruit. Less fertile soils are often favoured for table grapes.

Good wine is too expensive.

Q: Why did 12 bottles of vino get launched into space? A: To study the effects of microgravity and space radiation on the aging process of wine. The wine is part of a month experiment being conducted by the Luxembourg startup Space Cargo Unlimited to study how the aging process of wine is affected by microgravity in space. As a control group, samples of the space-bound wine will remain here, amongst us humans on Earth, and will be aged simultaneously for the same month period. Both Earth and space samples will be kept in a sealed glass bottle at a constant temperature of roughly 18 degrees Celsius. Upon orbital return, wine comparisons will be made to determine if there are taste differences that result from the effects of microgravity and space-based radiation , along with the measuring of physical and chemical reactions of the fermented grape juice. Sampling wine affected by space radiation sounds like the origin story of a new Marvel superhero.

Have you ever wanted to make homemade wine? Here's how. In theory, making wine is very simple.

The basic procedure of red wine production is outlined in the diagram. An important point in making red wine is that the fermenting must consists of juice skins and seeds. As a result, the composition of red wine is determined by the constituents extracted from skins and seeds in addition to those present in the juice. Red wines are made into a variety of styles. The stylistic differences are based on differences in wine characteristics such as grape variety, color, flavor, body, mouthfeel, and aging potential. Many factors such as a variety, soil, climate, growing conditions, and viticultural practices influence the fruit composition, and therefore, the style of wine that can be produced. In addition to fruit composition, winemaking techniques also play an important role in determining the wine style. Many varieties are available for red wine production. The wines are usually produced as varietals, or as blends containing several varieties. A list of commonly used red wine varieties is given in Table 1.

Due to the nature of grape production, considerable production can be obtained on a limited amount of land. Depending on the variety produced, marketing can be either wholesale for juice, wine, or the fresh market or retail primarily fresh table grapes. This marketing diversity can easily fit into current production practices. Because of the high cost of establishing a vineyard, you should carefully research all aspects of this enterprise, including market demand, before investing in wine grape production. According to the Pennsylvania Orchard and Vineyard Survey , Pennsylvania has commercial vineyards comprised of 11, acres of grapes, which produce an average of 5. Vineyards with more than 20 acres make up 92 percent of the production in Pennsylvania. Concord grapes for juice account for 77 percent of total grape production, while table grapes account for only 2 percent. Although Erie County accounts for 72 percent of grape production in Pennsylvania, wine grapes are grown on a small scale throughout the state.

Red Wine Production

Wine making has been around for thousands of years. It is not only an art but also a science. Wine making is a natural process that requires little human intervention, but each wine maker guides the process through different techniques. In general, there are five basic components of the wine making process: harvesting, crushing and pressing, fermentation, clarification, and aging and bottling. Wine makers typically follow these five steps but add variations and deviations along the way to make their wine unique. Harvesting is the first step in the wine making process and an important part of ensuring delicious wine.

How to Make Wine at Home

The philosophy of new monastery wines, which recover local varietals mainly trepat, garrut and garnatxa , is to transmit the characteristics of the grapes they are made from and the terroir they were grown on. This is achieved through non invasive winegrowing and by recovering the winemaking techniques of the monks of the Cistercian Order. In this way, the company acquired its presence in one of the most prestigious and important viticulture regions of not only the United States but also the world.

One small step for grapes: the history of wine in space

The first thing to do when grapes arrive in the winery is to assess their quality by analyzing important parameters, such as total acidity, colour, degree of alcohol and physical condition. According to these parameters grape will be classified into different quality groups, rejecting the fruit that does not reach the required levels for our wines. The grapes used for ARO, Torre Muga and Prado Enea are harvested in small boxes 20 kg capacity so that they get to the winery in perfect condition.
