Sherry Flashcards
In what province is the city of Jerez located?
Andalusia
How old is viticulture in Andalusia?
It dates back to the Phoenicians, who settled there around 1000 BCE
Why was wine consumption prohibited in Spain between the 8th-13th century?
The Moors (Islam) ruled in Spain
Only consumption was illegal. Grape growing and winemaking continued during this period
Which countries rapidly increased importing Sherry at the end of the 13th century?
England, Ireland, the Flemish (Netherlands)
What were two advantages Andalusian wines had in the international market?
- Free trade agreements with England and France
- Global exploration/conquering the Americas meant Sherry was being shipped worldwide
What is the Consejo Regulador?
Spain’s first regulatory wine council, controlling the production and trade of Sherry
When was the Consejo Regulador established? What necessitated a regulatory body?
1935
Large commercial success in the late 19th and early 20th centuries led to foreign imitations of Sherry, often of poor quality. The Consejo Regulador set regulations for the production and trade of Sherry
How did demand for Sherry fluctuate in the 20th century?
- WWII caused a decrease, but recovered after
- Peak production hit in 1979 at 1.5 million hL
- 50% decrease in demand by the end of the 80’s
What was the result of decreased demand for Sherry towards the end of the 20th century?
A large surplus of cheap, poor-quality Sherry
What was Ruiz Mateos S.A (Rumasa)?
An almacenista that began shipping it’s own Sherry in 1950
What was Rumasa’s largest commercial success?
Becoming a major supplier for Harvey’s of Bristol. The brand Bristol Cream was of particular importance.
What steps did Rumasa take to dominate the Sherry industry?
- Acquired and consolidated smaller bodegas
- Purchased hotels, banks and other businesses
- Drove down the price of Sherry through its large market influence
When and why was Rumasa nationalized?
1983, due to millions in unpaid taxes
How did the Spanish government’s nationalization of Rumasa affect the Sherry industry?
- Its bodegas were sold off, leading to large scale unemployment and social unrest
- Other independent bodegas closed because they couldn’t compete in a market filled with high volumes of inexpensive, poor-quality wine
After the fallout from Rumasa’s nationalization, what steps have the Consejo Regulador taken to promote Sherry?
- Regulating amount of vineyard plantings
- Regulating stock levels
- Promoting Sherry as a quality product
At what latitude is Jerez located?
36 degrees
At what altitude are the vineyards in Jerez located?
0-90 meters
What’s the largest moderating influence on Jerez?
The Atlantic Ocean
Describe the general climate of Jerez
Hot, mediterranean climate
Hot, dry summers and relatively rainy winters
What is the Poniente? Why is it important to the climate of Jerez?
A cool, damp wind coming from the Atlantic
It serves as a cooling influence and adds humidity during the summer
What is the Levante?
Why is it important to the climate of Jerez?
A hot, drying wind coming from North Africa
It creates a more arid climate
How does Jerez’s arid climate affect the time of harvest?
Grapes transpire at a quicker rate, leading to a higher concentration of sugar
Why would an especially hot year be a particular challenge for Fino/Manzanilla Sherry?
A high concentration of sugar can make it difficult to ferment dry and develop a layer of flor
How can the mediterranean climate affect canopy management in Jerez?
There are many cloudless days in the summer, leading to more hours of sunlight and potential for sunburn
What is the name of the delimited growing area for Sherry?
Zona de Producción or Marco de Jerez
How large is the Zona de Producción?
7,000 hectares
What are the two DO’s within the Marco de Jerez?
DO Jerez-Xérèz-Sherry
DO Manzanilla- Sanlúcar de Barrameda
Besides fortified wine, what is allowed to be produced from grapes within the Zona de Producción?
Sherry Vinegar
What is the one grape used in DO Jerez-Xérèz-Sherry that is allowed to be sourced from outside the Marco de Jerez? Where else can it be sourced from?
Pedro Ximénez (PX)
The grapes can come from around Montilla
What is a “pago”?
A smaller delimited area thought to produce distinct wines
Can pagos be included on DO Jerez-Xérèz-Sherry labels ?
Yes, as of 2021
What is the name of the key soil in Jerez?
Albariza
What makes up albariza soils?
Limestone, silica and clay
How does the limestone in Albariza soils assist viticulture?
It was formed from shells of aquatic microorganisms 30 years ago, creating a porous soil that is spongelike when wet.
It is able to retain water well, which is crucial during hot, dry growing seasons
What role does clay play in albariza soils?
It water moisture from winter rains and gradually releases it throughout the growing season
How is albariza’s crust advantageous for viticulture in Jerez?
- It forms a dry crust on the surface, which prevents water from evaporating
- Its light color reflects sunlight, aiding in ripening, and not retaining heat so diurnal temperature shift is larger
What major benefit does albariza provide for grape growers?
It allows for higher density plantings and higher yields (70 hL/ha)
What’s the average planting density in Jerez?
3,500-4,000 vines per hectare (compared to 1-2k vines/ha in La Mancha)
Why are higher yields acceptable for grapes making Sherry?
Most of the flavor is coming from the maturation process, and not the grapes themselves. Concentration is less of a concern.
Besides albariza, what are two other types of soils in Jerez and what are their major characteristics?
- Barros - Higher clay content
- Arenas - Higher sand content
What percent of grapes grown in Jerez are Palomino?
97%, with Moscatel and PX splitting the remainder
What are two aliases for Palomino?
Palomino Fino, Listán
What 5 characteristics does WSET give for Palomino?
- Mid to late ripening
- Grows well in dry, sunny weather
- High yielding
- Loses acid quickly as it approaches ripeness
- Neutral in flavor and aroma
What are two aliases for Moscatel?
- Moscatel de Chipiona (named after the town of Chipiona)
- Muscat of Alexandria
What kind of soil will you most likely find Moscatel grown on?
Arenas soil - sandy, like the soils found in Chipiona
What are the 4 characteristics WSET gives for Moscatel?
- Late ripening
- Well adapted to heat and drought
- Aromatic grape variety
- Usually used for sweet Sherry labelled “Moscatel”
What is PX used for in Sherry?
Sweet fortified wine, either bottled varietally or as a sweetening agent in blends
What percentage of vineyards area within the Marco de Jerez is planted with PX?
1%
Besides the Marco de Jerez, where else can PX come from?
Montilla, in the province of Córdoba
Usually shipped as young wine, but also as raisins or fresh grapes
What are the three characteristics WSET gives for PX?
- Small, thin-skinned grape
- Neutral in flavor and aroma
- Capable of accumulating high levels of sugar
What’s special about PX production?
Grapes are left to dry in the sun after picking to concentrate sugar
How many local varieties were recently permitted for use in the production of Sherry?
6, all grown locally pre-phylloxera
Why are Sherry vineyards currently being transformed?
To accommodate mechanization of pruning, harvesting and soil management
What used to be the principal vine training method? What is it called in Jerez?
Replacement cane pruning, or Vara y Pulgar
What kind of vine training are growers increasingly switching to?
Single or double cordon, spur pruned, VSP
What is an increased risk caused by VSP training in Jerez?
Sunburn, but more canopy shading helps
What is a typical vine spacing in Jerez?
Intra-row: 1m
Inter-row: Enough to fit a tractor lol
What is the maximum yield allowed for Sherry vineyards?
80 hl/ha, but it’s not common
What are common yields for Sherry vineyards?
60-70 hl/ha
What is the topography of most Sherry vineyards?
Gentle slopes (10-15 degrees), where albariza is normally found
What is the process of “aserpia”? Why is it done?
The practice of creating troughs within the rows after harvests.
It helps the vineyards retain water from winter rains rather than it flowing away
How is aserpia accomplished?
Traditionally, manually, but its mostly mechanized now
What rootstocks will you mainly find in Sherry vineyards?
333EM, 41-B and 13-5 EVEX (all hybrids of V. vinifera and V. berlandieri)
What are 3 reasons why 13-5 EVEX is an important rootstock in Sherry?
- It’s well adapted to limestone soils, which can help prevent chlorosis
- It’s drought resistant
- It produces good yields
What are the most significant pests/hazards in Sherry vineyards? What are the typical solutions?
- Chlorosis (due to limestone heavy soils) : 13-5 EVEX rootstock
- Drought : Drought tolerant rootstock (13-5 EVEX rootstock)
- Powdery mildew in the Spring/fungal disease : VSP (air circulation) and systemic fungicides (if disease is present)
- European grapevine moth : Pheromone traps (sexual confusion)
When does harvest usually start in Sherry?
1st week of August in the more inland vineyards, finishing by the 2nd week of September for the cooler coastal sites
PX and Moscatel tend to be harvested a little later
Why are Palomino grapes harvested earlier?
To avoid rain and rot.
Phenolic and flavor/aroma development aren’t huge considerations for Palomino because a) the wine gets its character from maturation, and b) it’s getting pressed immediately after arrival at the winery
What’s a normal potential alcohol for Sherry grapes at harvest?
12% ABV
What’s a normal level of acid for Sherry grapes at harvest?
5g/l or 3.3-3.5pH
Why might acidification be necessary for Palomino?
Palomino loses acid quickly at harvest (should be at 5g/l when picked)
What percent of grapes are harvested by machine in Jerez?
60% by machine
At what time of day are grapes harvested for Sherry production?
At night/early morning to prevent oxidation and microbial spoilage
How much skin contact is allowed for Palomino grapes?
As little as possible. Grapes are pressed immediately upon arrival at winery.
Why is skin contact bad for biologically aged wines?
Phenolics prevent the formation of flor
What is “Primera Yema”? What is it used for?
The first and lightest press. Used for, along with free run, biologically aged wines
Primera Yema and free run juice make up what percentage of total juice yields?
60-75%
Is free run/primera yema allowed in Oloroso Sherry?
Yes
Because they make up so much of the yield (60-75%), they’re often included in Oloroso production for producers who mainly make that style (Eg. Fundador)
What is the “segunda yema”?
The second press, which is used for oloroso because it will be higher in phenolics
What is the “Prensa”?
The Prensa is the last press fraction
- Typically fermented in new casks to prepare them for future use
- Distilled into a grape spirit
What’s the maximum permitted juice yield for Sherry production?
70 L/100kg grapes
Why is juice clarified before fermentation in Sherry production?
Albariza soils are dusty, and the sediment needs to be discarded before fermentation
What are the options Sherry producers have for clarifying juice before fermentation?
Cold settling, centrifugation, flotation
Is must from different vineyard sites typically fermented separately?
Yes
What kind of yeast is typically used in Sherry?
Cultured yeast
For base wines in Sherry, what’s the typical range for temperature during fermentation?
22–26°C (72– 79°F), medium-high temperatures
Why do Sherry producers typically let the must ferment at warmer temperatures (72-79°F)?
Because Palomino is a relatively neutral grape and most of the flavor will be coming from maturation, it’s not as important to retain the fruity aromas and esthers
What’s a typical vessel for Sherry fermentation?
Stainless steel mostly, with a small number of producers using old oak to add richness
When is the vast majority of sugar converted during fermentation? How long is the entire process?
The first 7 days
A few weeks
Why does the remainder of the fermentation process happen at a slower rate?
The higher alcohol levels make it more difficult for yeast to function
Why is MLF not wanted for Sherry production?
Acid is already low, and buttery flavors aren’t wanted
