![]() | The Origins of Port Port Wine, originally referred to as "Red Portugal," now called "porto" or just "port," is brandy-fortified wine made from the grapes of the Douro Valley in northern Portugal. The region itself consists of an officially demarcated area of approximately 1,000 square miles, and it stretches from about 60 miles east of the city of Porto along the Douro River to the border of Spain. Most Port wines are red, but a white variety is also available. Port, which gets its name from Porto, the second largest city in Portugal, is typically served after dinner as a dessert wine. |
How Port is Made Harvest is in late September and early October. There are many different local grape varieties of which about a dozen are used for Port. The grapes are harvested by the "roga", a traditional group of harvesters from a closely-knit community, that by tradition returns to the same "quinta" or farm every year. They work from sunrise to sunset until all the grapes are harvested. The grapes are then crushed and partially stalked. Fermentation begins and continues for between 36 and 48 hours.Pure grape brandy is then added to the wine to stop fermentation before the yeasts consume all of the grape sugar, thus a sweeter wine (with a higher alcohol content -- at least 33 proof) is produced. The young Port is allowed to settle for a few months in vats or casks made of oak or mahogany before being taken to the maturing lodges in VilaNova de Gaia near Porto. Here the Port wines are left to mature anywhere from 3 to 50 years.

Welcome to the our little world of Wine Wisdom.Wine wisdom is our attempt to pass on some of the more interestingfacts, history and processes that make the wine, that we so covet,so very special. Wine is made in many different styles, methods andis made in every region of the planet. There is a lot of history andlore dating back to ancient civilizations and many winemakers andgrowers have stories to tell and we hope to present a little of thathere. Some of the articles will be unique to here but all of ourtechnicle articles and interviews from our newsletter will be postedhere for future reading. We will add a searchable database in thefuture when the article list gets longer. We appreciate any input and/or suggestions and if you have an articlethat you think might interest other Wine Connosieurs, we would love toreview it and if we think it is worthy we will post it on our site withyour buyline and send you a bottle of wine as our thanks.

The term dry wine probably is one of the most misused terms in the wine world by the average consumer. The truth is most of the wine that people consume on a daily basis are technically considered dry. The term "dry", in reference to fermentation technically means that there is less than 1% residual sugar in the wine. Most people generically use the term to describe a wine in where they taste no sweetness. A wine can be fermented "dry" and still taste sweet.
During fermentation the yeast consumes the sugar in the grape juice producing alcohol and CO². The yeast will continue this process until all of the grape sugar has been used up at which point having no food source, the yeast cells die and become the lees. Wine is fermented to dryness because, among other things, leaving sugar in it would make it microbially unstable. Residual sugar in a wine which contains less than 16 % alcohol creates a substrate for possible yeast growth, making the wine potentially unstable or liable to re-ferment in the bottle.
Most enologist consider primary fermentation as complete when residual sugars are in the range of 0.1-0.2%. Using the reducing sugar measurement, wine below 0.2% are generally considered stable in regard to the possibility of re-fermentation in the bottle. At the point most of the residual sugars present are pentoses which are unfermentable by saccharomyces yeast. However it is possible for microbial activity to occur even when sugar are at less than "dry" levels. Brettanomyces, a spoilage yeast, can utilize residual sugars well below the 0.2% level.
The standard range of residual sugar for table wine (wine you drink with dinner) is 0-3%. The following is a typical scale used to classify the sugar level in wine.
Residual Sugar | Technical Classification |
less than 0.5% | bone dry |
0.5 - 1 % | dry |
1 - 2 % | semi-dry (medium dry) |
2 - 3 % | semi-sweet (medium sweet) |
more than 3 % | sweet |
It is a misconception that dry wines cannot taste sweet. The sweetness of a wine on the palate is greatly influenced by the level of glycerol, alcohol, acidity, and tannins in the wine. Even the serving temperature of a wine can affect how sweet it tastes.
So, a "bone dry wine" with a residual sugar level of less than 0.2 % but one that is relatively high in alcohol and glycerol can actually taste somewhat sweet.
Sweet dessert wines can range from 1.2 % to 20 % residual sugar. In wines such as Sauternes where the grapes are picked at very high brix, fermentation stops at about 15 % alcohol as the alcohol begins to act as a preservative drawing all of the water out of the yeast cells. In the case of Port wines, alcohol is added to the wine to stop the yeast fermentation.
The post fermentation integration of grape sugar is not uncommon. Grape sugar masks the effect of acidity and tannin in a wine. Sometimes, grape sugar is added back after fermentation to disguise (hide) defects in lesser quality wines. That's why "jug" wines are usually fairly sweet - to hide flaws caused by using less expensive grapes.

Organic Wine The Myths, Legends and finally, as we understand it, "The Truth". As the food and wine industry addresses the consumers growing concern about what they eat and drink, there are a growing number of wineries who are producing wine that in one way or another can be called "organic". Organic and sustainable farming has been practiced at small wineries since the beginning of the industry. A great portion of European wineries and sections (rapidly growing sections) of US wineries have been farming organically and using sustainable agricultural methods for decades. Many small wineries do not get certified because of the extra cost of getting approval from a Government or other certifying organization. However, they have chosen to grow their grapes utilizing eco-friendly practices for their own reasons. There is some confusion on exactly what "organic" means as it applies to wine and how they are labeled. Some wines are labeled as "100 Percent organic" while others say that the wine is .made from organically grown grapes". There are also many confusing layers of official Government agencies and other bureaucracy including counties, cities, states, regions, appellations and nations trying to regulate and set standards. In addition, there are several non-profit organizations that certify organic growers. Hopefully the following will eliminate some of the confusion. In the United States, the US Department of Agriculture (USDA) has been responsible for setting standards for organic products in the US since 1990. Unfortunately organic wine producers hit the wall with the Bureau of alcohol, Tobacco and Firearms (ATF), (responsible for regulating wine labels) who didn.t allow for a wine to be labeled as organic even if the USDA did. After 12 years of discussion, the USDA created the National Organic Program (NOP) in 2002 to implement label standards and oversee the production, processing and certification of all organic producers of food and other products in the US. After combining and simplifying all of the specifications and information from the various government agencies (USD, NOP, TTB, etc), you basically come up with four categories of eco-friendly wine. One important fact to remember is that most wineries prefer to add sulfites or sulfur dioxide (SO2) for preservation. I find that most wineries that do not add sulfites or sulfur dioxide make very inconsistent wine. In addition, the wine is very temperamental in normal conditions that most wine will experience in the supply chain. By using these methods, winegrowers using organic grapes are prohibited from labeling a wine as organic. This commonly utilized and arguably necessary step in wine production dramatically reduces the number of wines that might qualify as organic. This is an outline of the United States standards.
Europe and other nations have different sets of similar rules, but must follow the NOA for labeling and legal importation to the US Market. One of the most recognizable, and oft-discussed, styles of grape production in the organic world is Biodynamic agriculture. Biodynamic Agriculture was inaugurated in 1924 by Austrian scientist Rudolf Steiner. A worldwide movement, biodynamic agriculture is the oldest, non-chemical agricultural movement and pre-dates organic agriculture by some twenty years. Biodynamic farming and gardening does more than avoid chemicals; it seeks to work actively with the health-giving forces of nature. Farms and wineries, among others, may be certified Biodynamic by the Demeter Association, a national, independent, non-profit corporation. The US Government agencies go no further than 100% Organic when a winery is Biodynamic.
