Q

What is done in autumn to improve the water content of the Albariza. What does the Albariza do itself in the hot season to improve water retention

A

rectangular pits are dug between the vines to trap rainwater and reduce run off. These are filled in the spring. In hot season the soil grows a crust that reduces evaporation

25
What are the various levels in a Solera called
Criaderas
26
Summarize the Solera maturation process
Wines for bottling removed from the Solera System from the Solera. An equal amount of wine is removed from each Butt at that Criadera. These butts are replenished with an equal volume of wine from the next oldest Criadera and so on
27
What wine is used to fill the criadera with the youngest wine
Wine from the Sobretabla
28
How may criaderas can there be
Anywhere from 3 to 14
29
What happens to the younger wine when it is introduced to the older wine in the next criadera
It takes on the character of the older wine
30
What can jepoardize the consistency of the Solera system
If a poor quality young wine is introduced or if too much wine is removed each year
31
What is often done to minimise the risk of losing an entire solera system in a single catastrophic event
The butts are spread out in different locations
32
What does flor feed off and what does it produce
Alcohol and O2 producing CO2 and acetaldehye
33
What is it that gives biologocally aged Sherry its unique characteristics
Acetaldehyde
34
What conditions does Flor require to thrive. What time of year does it grow most vigorously
ABV below 15.5, high humidity and cool temps | Spring and Autumn
35
What does the layer of flor protect the wine from
Oxidation
36
Why does flor require replenishment of nutrients
It is constantly consuming alcohol and and other nutrients so fresh wine needs to be added periodically to refresh these
37
What is done to replenish nutrients throughout the solera
Wine is drawn off at regular intervals throughout the year.
38
What is the typical average age of the biological wines in a solera. At what age do the nutrients in the oldest criadera ( solera ) drop to a level where the flor can fail and oxidation begins
3-4 years | 7 years
39
Which wines are aged oxidatively
Olorosa, PX and some Muscat Sherry | Amontillado is aged oxidatively after a period of biological aging
40
How long are some oxidatively aged sherries aged. What happens to the ABV over time
Up to 30 years | ABV can rise to 22% as water evaporates

True
43
What happens to the sherry before bottling
Fined and filtered
44
What are the dry styles of Sherry called. How have these been aged. What is their profile
Fino and Manzanilla Biologically Pale lemon with aromas of citrus fruit, almonds and herbs. Bready notes from the flor. Sometimes tangy or salty
45
How do the sherries from Sanlucar de Barrameda compare to Jerez. Explain any differences
The area is cooler and more humid so a thick layer of flor is present year round. This results in a more tangy flavor
46
What are sherries which have not been filtered or fined labelled as
en Rama
47
What is the name of the sherry which has undergone only oxidative aging. What is its profile
Oloroso | Deep brown, full bodied, toffee, leather, spice and walnut
48
What negative character can old oloroso develop. How is this mitigated
An astringency which can be neutralized by blending with younger wine
49
What are Amontillado's, what is their profile
Biologically aged first then refortified to 17% to kill the flor and introduced into an Amontillado solera system. Amber or brown, less full bodied than Oloroso, combine yeast derrived aromas with oxidative ones ( yeast aromas fade with age )
50
How are Palo Cortado sherries described.
Aromas of Amontillado and body and richness of Oloroso.
51
When are Palo Cortados sometimes identfied
At the second classification
52
Palo Cortados can be difficult to tell apart from Amontillados and Olorosos but what can be said about them

60
Describe the aging process of medium sherry and Cream sherry. How are the premium wines in this category sweetened
Biological and Oxidative / Oxidative only | Sweetened with PX sherry
61
What do the best meduim and cream sherries taste like
They balance the toffee, leather and walnut flavor of the dry wine with the dried fruit notes of the sweet wine
62
True or false. The terms Oloroso, Amontillado and Palo Cortado can be used for either dry or sweet wines
False. Dry only as a result of recent law changes
63
In general how are Ports made
By adding grape spirit to a fermenting wine
64
True or false. Port can be made in red, white and rose styles
True

67
Broadly speaking what is the climate. The region is shielded from the cool rain bearing Atlantic winds by what geographic feature. What is the climate variation between the 3 regions
Warm continental. Serra do Marao mts Baixo Corgo in the W is coolest and wettest. Increasing heat and dryness the further east you go
68
What do Port growers have to contend with in terms of adverse weather
Frost in spring and heavy rainfall during flowering and harvest. Summers are very hot and dry
69
What allows viticulture to be possible in the adverse summer weather conditions
Schist bedrock that is fractured vertically allowing roots to travel deep accessing water reserves built up over the winter.
70
Describe the topography of the Baixo and Cima Corgo regions
Vines planted on the tall steep slopes on the banks of the Douro river. Some site deliberately use North facing slopes to avoid the scorching sun
71
What are the terraces on the steep banks of the Douro known as. What are they supported by
Socalos. Stone walls
72
What are the newer system of Douro terraces that allow some level of mechanisation called. What allows the mechanisation
Patamares | The terraces are built wide enough to allow access by a tractor
73
What is the name for the unterraced system used in Port. When is it possible to use this. How are the vines planted and accessed
Vinha ao alto may be used when the slope is not too steep Vines are planted up and down the slope and accessed via roads that cut across the slope from where machinery is operated by winches
74
What is the downside of the vinha ao alto and patamare systems
They are prone to errosion
75
What are the 5 varietals preferred for premium Port production in Douro. What do they have in common
``` Touriga Nacional Touriga Franca Tinta Roriz Tinta Cao Tinta Barroca Thick skinned, high in tannin, black fruit and floral aromas ```
76
How long does a Port fermentation typically last. At what ABV is the wine fortified
24 - 36 hours. 5 - 9 % ABV
77
Why are the typical extraction methods used for regular wine not practical for Port
The short ferment time does not allow sufficient extraction of color and tannin
78
What special techniques are employed to speed up the extraction process in Port production
Foot Treading Autovinifiers Piston Plungers and Robitic Lagares
79
Describe the process of foot treading
Large teams of workers tread the grapes for 3-4 hours in large shallow granite troughs called Lagares. Once fermentation begins the treading stops and the cap is regularly punched down
80
Describe Autovinification
Ferment occurs in a sealed vessel. As CO2 pressure rises the liquid is forced up through pipes into a holding tank. Once pressure is built up enough it is released and the liquid falls back down over the cap and the process starts over.
81
How often might the autovinification cycle occur when the ferment is very active. What does this mean in terms of skin contact compared to pumping over
Every 15 - 20 mins | Skin contact is much higher than pumping over
82
How do Piston Plungers work
Round shallow open top SS tanks where the cap is pushed down with robotic pistons
83
What is a robotic lagar
Shallow rectangular SS tank around the same size as a traditional lagar. It carries a self propelled gantry with the feet imitating the motion of human feet. Once ferment is done the tanks carry out regular punch downs
84
to what level is port normally fortified
19 - 22 % ABV

agurardente. 77% ABV | Requires a significant amount of spirit. 20% of the finished wine will be spirit. ( 3.5% for Fino sherry )
87
In what location is Port generally matured - why
Vila Nova de Gaia. The coastal climate is cooler and more suited to the slow maturation of port
88
Which wines do not follow this trend of maturing in VNdeG and remain in Douro. What is the effect
Wines destined for Tawny Port. The wines mature more quickly in the higher temps and lose color as a result
89
What 2 styles of red port are a direct consequence of the vessel selected for aging
Tawny and Ruby Port
90
True or False. Many ports are aged in new oak
No - new oak flavors are not desirable in any Port
91
What styles of Port are bottled after a relatively short aging process in large oak vats or SS vessels. Why
Ruby, Reserve Ruby, LBV and Vintage Ports | To minimise exposure to O2 and maximise the primary fruit character
92
Of the Ports which are aged non oxidatively which are fined and filtered. Do these benefit from bottle age. What is their flavor profile
Roby, Reserve Ruby and some styles of LBV Primary fruit, concentrated,
93
Which ports are not filtered or fined before bottling. Do these benefit from bottle aging ?
Some LBV ports and all Vintage ports. These benefit from long bottle aging
94
What flavors do long bottle aged vintage ports have
Garnet color, tertiary cooked fruit and vegetal notes ( prune, leather, wet leaves )
95
In contrast to Ruby and vintage ports describe the aging process of tawny ports. What are the barrels called that are used
Long oxidative aging process | Pipes
96
What happens to the color and flavor of tawny Ports over time during maturation. Do these benefit from filtration and bottle aging
They go from ruby to garnet to tawny in color. Fruit flavors fade and becomes raisiny and is accompanied by flavors of coffee, caramel, chocolate, and walnuts The wines do not need filtering and do not benefit from bottle age
97
Describe inexpensive Ruby port
blend of wines that are between 1 - 3 years old. Lack the complexity, concentration or tannins of premium ports
98
Describe inexpensive tawny port
These wines although tawny in color have not gone through an extensive oxidative again process. They are no older than cheap Ruby port
99
What options does a winemaker have for adjusting the color of cheap tawny port without aging it
Use of lighter wines from Biaxo Corgo Blending in white port Hot maturation in Douro Heavy fining to remove color
100
What is reserve port
ruby or tawny port that is deemed by a panel to be of sufficient quality. Reserve tawny must be aged in wood for at least 6 years
101
What are LBV ports
VINTAGE wines that have undergone at least 4 - 6 years aging typically in large oak vessels prior to bottling. They are more approachable than Vintage Port on release. Filtered LBV is similar in style to high quality Reserve Ruby Port and will not need bottle age
102
Can unfiltered LBV be bottle aged
Yes. These are similar in style to Vintage ports
103
Which ports require decanting
Unfiltered LBV and Vintage
104
What are tawny ports with an indication of age. How can they be labelled
undergo a long period of maturation in pipes. They can be labelled as 10, 20, 30 or 40 years old. This is an average age
105
What must be included on a label of a tawny port with indication of age - why
Year of bottling | Wine loses its freshness after bottling
106
what are tawny ports with indication of age considered to be
The best tawny ports
107
When must a producer declare an intention to release a vintage port and when must it be bottled
In the second year after harvest. Bottled in the third
108
Prior to bottling a vintage port how are they aged
in large oak or SS vats
109
Roughly how often is a vintage port released
perhaps 3 times a decade
110
when by general agreement of most producers was a vintage port released in the last 20 years (4)
2000, 2003, 2007 and 2011
111
What are single estate vintage ports labelled as
Single Quinta ( name of the estate or quinta appears on the label )
112
when would a large port producer with several quinta chose to release a vintage port / single quinta vintage. Which is considered higher quality
Vintage in the best years - single quinta vintage in the worst years. Vintage is best
113
What is the profile of Muscat. Where does it grow best
Low to med acid with aromas of orange blossom and grape. | grows best on warm / hot sites with some kind of cooling mitigation to preserve acid and aromas
114
Describe youthful, unaged Muscat
Med gold in color, floral and aromatic, sweet but rarely luscious
115
Give an example of a youthful unaged Muscat
Muscat de Beaumes de Venise from S Rhone
116
Describe production of youthful unaged Muscat
Grapes picked ripe and not dried, Some skin contact prior to and perhaps during fermentation. Fermentation is cool and stopped by addition of 96% ABV grape spirit Stored in inert vessels prior to bottling
117
What is the overall strategy of a winemaker when making a youthful style of fortified muscat
To preserve the primary fruit and aroma character
118
What is an example of an aged Muscat in a luscious style. What color is it likely to be
Rutherglen in Australia | Amber or Brown
119
What determines the style of an aged Muscat
Timing of the harvest, when the wine is fortified and type of aging
120
Describe production of aged luscious Muscat
Grapes picked when ripe but some are allowed to raisinate ( not too much or Muscat character is obscured ) Fermentation on skins. If luscious style then ferment will be stopped at 2% ABV Oxidative aging for decades in large old oak vats
121
Aged muscats develop what type of flavors. What is sometimes done prior to bottling some older Muscats
Pronounced oxidative flavors yet they still retain their Muscat character Freshening of the wine by blending with a small amount of youthful wine
