Ch.1 Introduction to Fortified Wines Flashcards
Define a fortified wine
- A wine that has had additional alcohol added
- either before fermentation is complete or
- after fermentation has finished
What is the WSET SAT (systematic approach to tasting) alcohol scale for fortified wines?
- LOW = 15-16.4% abv
- biologically aged sherries
- some youthful styles of VDN
- MEDIUM = 16.5% - 18.4% abv
- oxidised styles of sherry
- some Madeira
- some aged VDNs
- Rutherglen Muscat
- HIGH = 18.5% abv and above
- Port
- older, oxidised styles of Sherry & Madeira
How do different grape varieties play a part in fortified wine?
- Provide aromas and flavours
- Muscat VDNs (protective wine-making/early release)
- Even Rutherglen Muscat (despite warm, oxidative)
- Provide neutral base
- Palomino: all sherry aromas from maturation process
- Provide structure: acidity
- Madeira (esp Sercial/Verdelho)
- nb bone-dry/high alcohol makes some sherry seem acidic, but palomino low acid!
- Provide structure: colour and tannins
- Touriga Nacional and Sousão in vintage port
How does vineyard site and climate affect fortified wine?
- Influence base materials eg
- Vineyards in Duoro scored for location, aspect and altitude to determine how much port that land can make. Vintage ports made from vineyards with proven history
- Muscat de Frontignon (Languedoc) fuller, riper wines from low altitude v high altitude Muscat de St-Jean-de-Minervois
Factors affecting the timing of harvest in fortified wines generally
- Before rain, as humidity risks botrytis which is never desirable in fortified wine (even noble rot)
- As long as grapes healthy and no unripe flavours, some styles pick as soon as reaches legal min level of pot alcohol eg sherry made from Palomino
- For rich, high resid sugar styles like Ruthergen Muscat, PX and Moscatel sherry, grapes left longer to concentrate sugars
Do producers of fortified wines let white grapes macerate on their skins?
- Yes: Madeira, muscat-based VDNs and White Port for a limited time to increase body, texture and extract additional flavours
- NO for biologically aged sherries (eg Fino, Manzanilla) as phenolic compounds restrict growth of flor yeast.
What is the specific challenge in terms of colour with red fortified wines for long ageing?
- Red wines for long ageing need high concentrations of colour, tannins and flavours.
- These wines (eg port) are us sweet and made by adding fortifying alcohol midway through fermentation, limiting maceration to as little as 2-3 days.
- Therefore extraction techniques need to be very effective. Port has done this (mimicking feet) whilst remaining gentle enough not to crush seeds (bitter tannins)
- Obvs tawny & rosé ports need less extraction!
WHEN are fortified wines fortified?
- Either before (if sweet wanted eg port)
- or after (if want dry eg sherry)
- For most sweet, stop fermentation by raising the alcohol above which yeasts can operate and leaving (desired level of ) residual sugar that was in the grapes. Earlier = sweeter.
- Some sherries - Pale Cream, Medium & Cream fermented to dryness then sweetening component added (creating a diff style than if merely stopped midway). Cream sherry is often dry Oloroso blended with PX, combining aged dry Palomino with raisined PX.
Why is port’s fortifying spirit more important than most other wines?
- Most fortified wines use grape spirits of 95-6% abv
- such high alcohol means
- not much vol needed to reach required strength (us 15-22% abv) - less dilution of base wine
- neutral aromas & flavours do not mask characteristics of the base wine
- Port must use grape spirit 77% (+/- 0.5%)
- It has more character to impart and need significant volume to reach 19-22% required.
- Therefore spirit influential and many choose aromatic styles, esp in red ports. But delicate for rosé port.
What are the four methods/ styles of maturation in fortified wines?
- Unaged eg VDNs like Muscat de Beaumes de Venise, ruby /rosé ports (NOT sherries) - primary fruit/ youthful style, often stored in stainless steel/ concrete
- Aged in bottle eg Vintage port/ unfiltered LBV. Stored in old oak for few years before bottling. Made to age in bottle, so concentrated and tannic on release. Fresh fruit becomes dried, savoury, tannins soften/integrate.
- Oxidative ageing eg Tawny ports, madeiras, some VDNs & sherries (Oloroso, PX, amontillado, palo cortado) usually small wooden barrels: managing oxygen exposure: top up or not. Warm conditions (maderisation = heated/oxidised) accelerates. Aromas of nuts, caramel, dried fruits.
- Biological Ageing eg Fino, Manzanilla, Amontillado (also bases for cream sherries) Aged under a layer of flor yeast, protects wine from oxidation, lowers glycerol (and hence body) and contributes hay, acetaldehyde (bruised apple), bread dough, iodine, seaweed, almonds
What is Rancio
- Rancio is a tasting term used to describe aromas and flavours found in some styles of oxidised, fortified wines - oak/oxygen/time/sunlight interaction creates leather, wood, varnish, strong coffee
- Found in Grenache VDNs & older Rutherglens
If a wine has a stopper, not a cork?
It is ready to drink; and not suitable for future ageing
Why you blend fortified wines
- Balance Alcohol (high) must be integrated. Ageing concentrates wine/ loses primary fruit. Blend in younger wines for freshness eg Sherry, Rutherglen muscat
- Consistency Esp NV. Static maturation (diff vintages mature separately). Sherry - solera system = fractional blending. Modified solera system for Rutherglen muscat.
- Style Port blend of varieties for colour, tannin, flavour, ability to age. Sherries sweetened by PX. House styles
- Complexity
- Volume Small vineyards, diff producers. Small barrels for maturation
- Price Most wines need to meet specific price point.
What is en rama?
“on the vine” = raw.
When a sherry is very lightly fined or filtered or not at all. Usually more pronouced and complex.
The majority of fortified wines are stabilised, fined and filtered before bottling to ensure clean and clear. Which are not?
- Ports designed to develop further in bottle: Vintage, Single Quinta, Crusted and unfiltered LBVs.
- May need decanting
- Sherries “en rama”
