Q

What is the recent history Jerez, ie. Rumasa? 5 facts.

A

Rumasa, aka Ruiz Mateos S.A.

1950: Started as an almacenista, eventually an exporter

late 1970s: Supplied Harveys of Bristol with wine, making a lot of money.

Began buying up bodegas, hotels, banks etc., and drove down prices with consolidation.

1983: Gov nationalized company due to owed taxes; bodegas were sold and unrest ensued with unemployment/business turnover

Consejo continues to try and regain balance

Q

What are the 3 soil types for Sherry and what are their characteristics?

A
  1. Albariza: the predominant soil type; a blend of Limestone, silica and clay.
  • Clay retains some moisture when it rains
  • When it dries, it forms a crust, preventing evaporation
  • Light colour reflects light and aids ripening
  • Moisture retentive qualities allows for high yields
  1. Barros - more clay content
  2. Arenas - more sand content

Q

Describe the Training and Trellising system and spacing commonly used for Sherry and the purpose it serves.

A
  • “Vara y Pulgar” - aka replacement cane; increasingly replaced by single- or double cordon w/spur pruning (to allow for mechanization)
  • VSP, with shading to prevent sunburn, and airflow to prevent disease. (Suited to mechanization)
  • Spacing: Tight within-row at 1m (for high yields); between row just wide enough for tractor (mechanization)

Q

Describe the winemaking process for Sherry up until the maturation/Solera phase (9 steps).

A
  1. Grapes are pressed immediately to avoid skin contact
  2. Free run & lightest pressings, the Primera Yema, are separated for biological wines (some Oloroso)
  3. Juice is clarified via cold settling, centrifugation or flotation
  4. Wine is fermented using cultured yeasts at 22-26 degrees for reliability/neutrality in Stainless (sometimes barrel) for approx. 3 weeks
  5. Wine is chilled or SO2 is added to prevent MLF, maintaining acidity/avoiding butter
  6. First Classification occurs: wines are tasted/analyzed to designate for biological (lighter, delicate) vs oxidative ageing (fuller, intense -Oloroso)
  7. Wines are fortified to 15-15.5% (biological) or 17% (oxidative) using 95% neutral grape spirit
  8. Wines are stored in the Sobretablas in tank or barrel for several months
  9. Second Classification occurs: biological wines are tasted/analyzed and inspected for freshness/flor and are marked as potential for Fino/Manzanilla (lightest), Amontillado (more intense) or Palo Cortado (most intense) (the former two still enter the Solera as Finos to start with)

Q

What are the maturation location regulations for Sherry?

A

Previously, maturation of wines labelled DO Jerez-Xérès-Sherry had to take place in the “Zona de Crianza”: in either Jerez de la Frontera, El Puerto de Santa María and Sanlúcar de Barrameda. Now, they
can be aged anywhere in the Production Zone. (BUT The maturation process for DO Manzanilla – Sanlúcar de Barrameda must take place in the municipality of Sanlúcar de Barrameda.)

20
Q

What is a Solera System, what is its purpose, and what is it made up of?

A

A method of fractional blending that maintains consistency and quality.

Young wines added provide “nutrients” (alc, glycerol, acetic acid) for the flor to consume and for biological ageing to continue.

It is made up of Criadera, or sections of barrels, each stacked in the same area.
ex.
The Solera - oldest wine
1st Criadera - next oldest
2nd Criadera - younger than 1st
3rd Criadera - younger than 2nd

21
Q

What is the simplified Solera process vs. the realistic process?

A
  1. Max 40% of the wine is taken from each barrel in the Solera (oldest) Criadera
  2. Same proportion taken from the 1st Criadera barrels (2nd oldest), is blended then used to top up the Solera Criadera barrels
  3. Process is repeated until the youngest Criadera is topped up from the Sobretablas.

In reality, wines can be removed early for blending purposes, and/or they could blend wines from different systems.

22
Q

What are the 2 rules of the Solera system?

A
  1. Max. 40% of a wine in a system can be removed for blending or bottling each year.
  2. All wine bottled and sold must be min. 2 years old.
23
Q

What 5 conditions are required for Flor to survive?

A
  1. 4 Strains of Saccharomyces cerevisiae, found on grape skins in Jerez and in bodegas
  2. Max. 15.5% alcohol
  3. Oxygen, ie. ullage with butts at 85-90% full
  4. Storage temp of 16-20C
  5. Humidity > 65%
24
Q

What are the 5 effects of Flor?

A
  1. Retains pale yellow colour by protecting from oxygen
  2. Consumes alcohol and releases acetyldehyde and its characteristics
  3. Consumers glycerol, lowering body/increasing dryness
  4. Reduces acetic acid (volatile)
  5. Dead yeast cells at bottom of barrel cause autolysis (notes and texture)
25
Q

What is different in the Solera system process for Fino and Manzanilla wines?

A

Given that Manzanilla solera systems have thicker levels of flor than Fino solera systems, they need replenishing with young wines more frequently to support this growth.

Hence, small volumes of wine will be released and bottled several times throughout the year to ensure that
the flor is constantly maintained.

(Manzanilla has lower acetyldehyde vs. Fino just owing to the yeast strains)

26
Q

What are 7 Effects of Oxidative Ageing?

A
  1. Colour changes
  2. Alcohol Increases (water evaporates quicker)
  3. Aroma, Flavour, acid and other compounds concentrate
  4. Glycerol and body rises
  5. Aroma and Flavours evolve from primary to tertiary/oxidative
  6. Acetyldehyde decreases
  7. Acetic acid and ethyl acetate (volatile acidity) increase slightly
27
Q

Describe the finishing & packaging stage for Sherry. (4 points)

A
  • Tartrate stabilization typical via contact process
  • Fining & filtered common, especially if biologically aged (flor removal)
  • Corks, cork stoppers, or screw cap used
  • Must be packaged/sealed in one of 3 municipalities
28
Q

Describe the style of Fino or Manzanilla Sherry (9 points)

A
  • Dry, <5g/L
  • Biologically aged
  • Pale lemon
  • Light to Med Bodied
  • Low Acid
  • Low Alcohol (15-15.5%)
  • Good to Outstanding
  • Inexpensive to Super Premium
  • Aromas of Acetaldehyde, bread dough, almonds
29
Q

Explain the difference between Fino and Manzanilla sherries.

A

Manzanilla Sherry must be matured in Sanlúcar de Barrameda to qualify as DO Manzanilla – Sanlúcar de Barrameda.

This area is nearer to the coast, has fewer temp extremes and higher humidity, causing thicker flor. That said, the yeast strain is slightly different and produces less acetyldehyde. This plus the oxygen protection producers a lighter/fresher character.

More frequent Manzanilla releases are common as the thicker flor requires nutrients more often.

30
Q

What are two special labelling terms used for Fino and Manzanilla?

A

Fino Viejo or Manzanilla Pasada describe wines made with biological ageing with a minimum average age
of 7 years.

The flor may be left to die naturally by not refreshing the barrels with new wine for around a year. The wines may then enter a solera system for Fino Viejo or Manzanilla Pasada - ?

31
Q

What is the process of making an Amontillado and what style is it (5 points)?

A
  • Starts in the Fino system, are later fortified to 17% (killing flor), then are matured oxidatively
  • Dry, <5g/L
  • Must have biological and oxidative ageing attributes
  • Inexpensive versions use young fino and undergo a short ageing period; expensive versions are longer maturing and more complex
  • Good to outstanding
  • Mid to Super Premium
32
Q

What is the process of making a Palo Cortado Sherry, what style is it (6 points) and how does it compare to an Amontillado?

A
  • Marked for more intensity/body at 2nd classification; enter the Fino system, and are later fortified to 17% (killing flor), then are matured oxidatively. They receive less time biologically ageing than an Amontillado.
  • Biological and oxidative attributes, with aromas similar to an Amontillado, but a palate more similar to an Oloroso
  • More glycerol, and less acetyldehyde vs Amontillado
  • Dry, <5g/L
  • Alcohol of 17-22%
  • Mostly Premium, some Mid
  • Very Good to Outstanding
33
Q

Describe the styles of Oloroso Sherry and how its made.

A

Fortified to 17% after fermentation/first classification and is oxidatively aged.

(If a producer mainly makes Oloroso they may use all or some of the Primera Yera for this wine)

  • Brown Colour
  • Dried Fruit, raisin, prune, caramel, walnut
  • Short maturation = Inexpensive and acceptable/good
  • Long maturation - Premium and Very Good/OS
34
Q

What is an optional labelling term for dry Sherry?

A

“En Rama” , applies to dry sherries that have not undergone clarification, fining or cold stabilization (filtering is permitted/optional). More intense/complex and more premium.

ie. Fino en Rama (most common)

35
Q

How are naturally sweet sherries made and used?

A

Grapes (commonly PX & Moscatel are dried and concentrated in the sun for 2-3 weeks

Fermentation stops at 4-6% (naturally due to high sugar) and wine is fortified to 15-16%

Matured oxidatively, often in a dedicated solera, further concentrating

Used as their own sweet style of wines, or as a blending component

36
Q

Describe the style of PX Sherry as well as the required and average sweetness levels

A
  • Full-bodied, syrupy
  • Low acid
  • Pronounced aromas of raisins, molasses, licquorice
  • Inexpensive to Premium
  • Good to Outstanding

Min. 212g/L ; Typ 450-550g/L

37
Q

Describe the style of Moscatel Sherry as well as the required and average sweetness levels

A
  • Protected, non-oxidative style
    or
  • Barrel aged at length
  • Aromatic
  • Inexpensive to Premium
  • Good to Outstanding

Min. 160g/L; Typ 325-375g/L (Sweet)

38
Q

How are sweetened styles of Sherry made and what calibre are they?

A

Fortified, aged, dry fermented Palomino has a sweetening component (ie. RCGM or PX) added.

Inexpensive examples might be young wines sweetened just before bottling.

Mid or Premium wines may be sweetened then matured further in a dedicated solera.

39
Q

What is Pale Cream Sherry and what is the style?

A

It is a short-matured biologically aged wine prior to sweetening, often with RCGM.

It has a light flor character and is medium sweet to sweet; inexpensive and generally acceptable to good.

40
Q

What is Medium and Cream Sherry and what are their styles?

A

A Sherry, that can be either biological or oxidative, that is sweetened typically with PX

Medium Sherry is Off-Dry to Sweet, but less than 115g/L

Cream Sherry is Sweet with > 115g/L

Both wines are inexpensive to premium and acceptable to outstanding depending on whether they’re using younger wines or oldered, matured Amontillado, Oloroso or PX wines.

41
Q

What are the age indication options for Sherry, what is the style and what are the requirements?

A
  1. VOS = Vinum Optimum Sigmatum = Very Old Sherry
    –> Avg age of 20+ years

VORS = Vinum Optimum Rare Signatum = Very Old Rare Sherry
–> Avg age of 30+ years

  • For the above, each small production batch is assessed by a panel for typicity and lab tested for age
  • Small amt of PX may be blended in to offset astringency
  • Very Good to OS, Premium to Super
  1. 12- & 15-yr-old Sherry
    Undergo tasting panel and lab test also, but they are annual and not by batch.
42
Q

What is the average holding size and what type of businesses own plantings within Sherry?

A

<3ha avg size of holding (small)

Owned by Co-op members 47%, Shippers 31%, Independent Growers 22%

43
Q

What are the 3 company registration types for Sherry and what are their roles and regulations?

A

(Multiple registrations are possible.)

1) Bodegas de la Zona de Producción: press grapes and ferment into base wine, which can be sold on.

Cannot qualify for DO-JXS or DO-MSDB if independent. But often have another registration.

2) Bodegas de Crianza y Almacenado (aka Almacenista): mature wines and sell to 3) (requirement)

Almacenista name can be included on the label however.

3) Bodegas de Crianza y Expedición: only companies permitted to sell or export DO-JXS or DO-MSDB.

Can also mature wines; or may source some or all from an almacenista.

Min stock required is 500L.

44
Q

What is the role of the Consejo Regulador for Sherry? 6 points.

A
  • Maintains vineyard registers
  • Sets max. yields
  • Sets min. alc. for base wine
  • Oversees stock rotation at bodegas
  • Promotional body (ie. Int Sherry Week)
  • Protects Sherry term (ie. 1990 campaign)
45
Q

What are recent vs peak Sherry sales, as well as sales current trends (4 points)?

A

Peaked in 1970s at 150 million L
- 46 million in 2009
- 31 million in 2019

Sweetened styles and Fino have declined dramatically. Manzanilla has declined, but not as much.

Palo Cortado, PX and age indicated styles are small volume but have become most profitable for shippers.

Premium sherries are increasing in some markets, ie. UK, due to niche hospitality sales.

Winemakers diversifying in unfortified styles using Palomino or PX (biological/fresh/young or partially oxidative)

46
Q

What are the export and domestic sales for Sherry?

A

Domestic market is largest @ 38% share of sales or 11.5 million in 2019 (Manzanilla/Fino most popular)

UK largest export @ 8.2 million, mostly sweet
Netherlands @ 4.7 million
Germany @ 1.7 million
USA @ 1 million

(all declining)
