Taste the wine and, if you need to adjust the oak level, re-add the chips to the racked wine, and let stand another week or two until the desired oak level is achieved. Be sure to top up the fermenter and secure it with a rubber bung and fermentation lock. Age the port for 6 months in the carboy while racking every two months to separate the sediments without the need for fining.
Fining is not required since the brandy acts as a clarifying agent. Optionally, it may be clarified with gelatin or coarse-filtered using No.
You may also adjust the sweetness to your taste before bottling by adding corn sugar or a wine conditioner. Note: Sorbate cannot be used to stop an active fermentation. Sorbate is only used in preventing renewed fermentation in sweet wines. It is not required in port because the high alcohol level already prevents any potential renewed fermentation in the bottle. If blending different varietals, experiment with different blends and ratios until you establish a combination you like.
Blend the batches of port according to the desired ratio, bulk-age the wine for a couple of months before re-tasting, and make any necessary adjustments to the blend. Port may be bottled in typical port-style bottles or any bottle type of choice. Port and other fortified-wine bottles are corked using a regular cork driven by a hand or floor corker. If you wish to keep with tradition like true port aficionados, use stopper-type corks; these are shorter corks with a plastic stopper.
They need to be sanitized by soaking in a sulfite solution for 15 minutes. Your family and friends will also be impressed by the quality. Some wine lovers probably knew the grape from Bordeaux blends.

Old rabelos outside one of the Gaia Port lodges In the past, Port wines were shipped down river to Vila Nova de Gaia on boats called rabelos. Leave a Reply Cancel reply Your email address will not be published. This last category is an exception, as these wines are from a single vintage [ 7 ]. All these wines are ready to drink when they are bottled [ 1 ].
Port wines that belong to Ruby style are wines that the evolution of their deep red colour is limited and the fruity character is maintained [ 1 ]. Crusted Ports are high quality, very full-bodied, deep coloured wines, obtained by blending wines from numerous vintages, aged for a minimum of 2 years in wood barrels and then bottled and aged during further 3 years.
The year in which the wine was bottled must be indicated on the bottle label [ 1 , 7 ]. LBV is a special single harvest and it is bottled after 4 to 6 years from the harvest, with the previous ageing in vats wood or stainless steel and has a deep ruby red colour, extremely full body and rich in the mouth.
To be recognised as Vintage, the wines must present an outstanding quality and with a very full bodied and have a deep colour. Vintage and LBV are good for storing since they age well in the bottle [ 1 ]. The types of Port wines made from red grape varieties vary in colour from deep purple to light gold, with transitional hues like tawny, golden tawny, golden and light gold.
White Port wines differ according to shorter or longer periods of ageing and different degrees of sweetness. The colour of White Port wines varies from pale yellow, straw to golden white. However, when aged in wood barrels for many years, white Port wines develop, through natural oxidation, a golden hue that is very similar to that of a very old Tawny Port wine made from red grapes [ 1 ].
The special categories inside this style are similar to those of Tawny Port wines [ 7 ]. White Port wine is a Port wine style with increasing market expression. The colour of this type of Port wine may go from light ruby to pale salmon. This style is commonly described as a light and fresh style of Port wine that is very fruity and enjoyable [ 1 ].
Different ageing processes leads to numerous Port wines quality categories, presenting different colours from white to deep purple , sweetness sweet to dry and a wide range of flavours.
The Port wines styles and categories are summarised in Figure 2. Port wines styles and categories according to [ 1 , 7 ]. When aged in old wood barrels their size depends on the Port wine style. Wine intended for Ruby and Vintage Port wine production will be aged in large wood barrels and that intended for Tawnies will be aged in small ones. The Tawny Port wine undergoes an oxidative ageing process, while Ruby and Vintage Port have a much less oxidative ageing termed reductive ageing process [ 1 , 7 ].
Ruby, Reserve and LBV Port wines usually age in large wood barrels for two, three years or even six years LBV and have a deep red youthful colour and intense fruity flavours, evocative of cherry and blackberry. Tawny Port wines 10, 20, 30 and 40 years old age for longer periods in small wood barrels and show nuttiness and aroma of butterscotch.
White Port wines usually age for two or three years in large wood barrels. Traditionally, White Port wines are fermented with skin contact like Red Port wines; in this case, the wines are aged in conditions that results in its oxidation. Nevertheless, the trend is for a shorter maceration period, to obtain White Port wines with a pale colour and fresh aromas [ 1 ].
Like Red Port wines, most White Port wines are fortified when half of the grape sugar concentration has been fermented. Semi-dry and dry White Port wines are fortified later, or when alcoholic fermentation is finished [ 8 ].
The fortification process gives a high concentration of acetaldehyde to the wines. Acetaldehyde is probably responsible for the colour stability by favouring the production of anthocyanin-tannin polymers discussed below [ 9 , 10 ]. The high sugar concentration retained tends to mask the bitterness of small flavanols, but not their astringency [ 8 , 11 ].
Young Port wines are generally sweet, intensely red with a high concentration in tannins and with a fruity aroma. The colour, aroma and flavour of young Port wines are due to compounds from the grape, from the alcoholic fermentation and from the wine spirit used for the fortification.
These wines need to age to develop the complex sensory attributes typically associated with the several Port wine styles. Port wines can be aged for a minimum of three years to a decade or more in old wood barrels to develop their character; normally it is aged in an old wood barrel, ranging from or L capacity up to , L.
The type and length of the ageing process, as well as the capacity of the ageing barrel, and the oxygenation during racking, influenced the Port wine style that will be developed depending mainly on the wine style planned. Therefore, wines destined for Ruby and Vintage Port wines will be usually aged in large wood barrels, while those intended for the production of Tawny Port wines will be aged in small wood barrels Figure 2.
Racking is a very important operation during Port wine ageing and may be performed periodically. The value of aged Tawny Port wine is linked to the characteristic aroma compounds developed during the ageing process in small wood barrels that allow the admission of oxygen. This oxidative ageing is influenced by factors such as oxygen levels, temperature, and pH. The age indicated on the label corresponds to a wine that has the sensory characteristics recognised by the IVDP of a wine aged in wood with 10, 20, 30, or over 40 years, obtained by blending wines with different ages.
Ruby Port wines have red colour, full-bodied structure and often still quite fruity in character when the wines are ready to drink. The flavour modifies from an intensely fruity, even spirity character when the wines are very young to a rich fruity ruby wine after 3 to 5 years ageing in wood. These wines age more slowly than those aged in smaller wood barrels, retaining their structure and fresh fruity aromas that are the main characteristics of these wines.
Some special Ruby Port wines the so called Vintage Port wines have a considerable bottle ageing process, giving lighter red wines, with often a very fruity character, despite having aged for two decades or more.
Vintage Port wines are aged in wood barrels for two or three years, followed by a considerable ageing time in a bottle in the so called reductive ageing 10 to 50 years or more before consumption , and so it develops a different character from those wines aged exclusively in wood barrels. These wines remain fruity and with a red colour. Consequently, Vintage Port wines develop much of its distinctive bouquet from a long process of reductive ageing in bottle.
After the initial period in wood, LBV wines are aged in dark glass bottles in cool dark cellars with controlled temperature, ventilation and relative humidity. The vintage year is always indicated on the label [ 1 ]. The western part of the valley possesses a Mediterranean climate that produces warm summers and a fair amount of rain, however as you move more inland toward the Douro Superior, the climate becomes more dry and arid.
The westernmost of the three subregions, Baixo Corgo, gets the most rainfall and has the coolest temperatures. Grapes grown in the Baixo Corgo are used largely for tawny and ruby Ports. In Cima Corgo, which is east of Baixo Corgo, the average temperature is higher and rainfall not as prevalent.
Grapes grown in Cima Corgo are considered better quality than those grown downstream. Douro Superior, the easternmost subregion, has the smallest volume of grape production, in part because of its river rapids and challenging geography.
The area is the warmest and driest of the three subregions, yet produces some of the best grapes. More than 80 grapes varieties can be used to produce Port. Touriga Franca is the easiest to cultivate and, therefore, the most widely planted variety.
Touriga Nacional, though the most difficult to manage in the vineyard, is seen as the most desirable. Thank You! We've received your email address, and soon you will start getting exclusive offers and news from Wine Enthusiast. The base for Port is made like any other wine.
