Cabernet Sauvignon has thick skins and small berries. Smaller berries mean a higher ratio of skin and pip to pulp, which translates directly into elevated tannin levels. This is one of the most tannic of all major red varieties. The tannin is structural rather than harsh in well-made examples, and it is what gives Cabernet its ageing potential: tannins act as a natural preservative and soften over time.

Cabernet Sauvignon is a natural cross of Sauvignon Blanc and Cabernet Franc. Merlot shares Cabernet Franc as a parent, making it a half-sibling. This parentage explains why Cabernet and Merlot are so frequently blended: they are structurally compatible. It also explains why even experienced tasters can find them difficult to distinguish in blind conditions. Both share the Cabernet Franc influence; the Sauvignon Blanc heritage in Cabernet Sauvignon accounts for the herbal, sometimes pyrazine-driven notes that appear in cooler-climate examples.

Cabernet Sauvignon is late-ripening and needs warmth to fully mature. In cooler regions, it develops green bell pepper and eucalyptus notes from methoxypyrazines retained when the grapes do not fully ripen. This is not a fault: some guests actively seek out that profile. In warmer climates the pyrazines diminish, giving way to black fruit, cassis, and chocolate. Knowing which profile is on the list allows a more precise recommendation.

Young, high-tannin Cabernet is a structural match for well-marbled red meat: the tannin binds with fat proteins and each makes the other more approachable. Aged Cabernet, with tannins that have softened over eight to twelve years, is a considerably more versatile food wine. A 2010 Napa Cabernet pairs with dishes a 2022 vintage would overwhelm. Worth knowing when a guest brings a special bottle to the table or asks whether to open something now or wait.

Pinot Noir has thin skins, which makes it susceptible to disease, frost, and oxidation during winemaking. Small climate variations produce significant changes in the finished wine. It is prone to mutation, which means even within a single vineyard the fruit can vary considerably from vine to vine. All of this makes it a higher-risk variety for growers and producers than Cabernet, and a primary reason for its price premium in quality expressions.

Pinot Noir is highly transparent to terroir. Where Cabernet Sauvignon can impose its character regardless of origin, Pinot reflects its site with unusual fidelity. Soil type, sun exposure, elevation, and aspect all show through clearly. This is why it is rarely blended: other varieties in the mix would obscure exactly what makes individual Pinot Noir interesting. It is also why wines are frequently vineyard-designated: the site is the point. Understanding this is useful when a guest asks why two Pinots from the same producer taste so different.

Pinot Noir's lighter body and high acidity make it one of the most food-versatile reds on the list. Lighter, more fruit-forward styles work with roast chicken, salmon, pasta, and mild cheeses. Fuller-bodied examples from California or Marlborough hold up to game birds and beef. Lean, high-acid styles from Oregon or Burgundy pair well with a broader range still, including dishes that would challenge most other reds: lamb, Indian cuisine, Chinese food, pizza. The only clear limitation is very hot, spiced food, where the wine's delicacy is lost.

Pinot Noir is pale in the glass, often translucent, which leads guests to expect a light, low-impact wine. The expectation is wrong. The aromatic complexity and palate weight of good Pinot Noir is significant. Worth flagging proactively for guests ordering their first Burgundy, particularly if they have ordered it alongside delicate food expecting something gentle to arrive.

In 1972, Sutter Home accidentally produced a stuck fermentation that left residual sugar in what should have been a dry rosé. The result was White Zinfandel: pink, off-dry, and enormously popular. The commercial success of this style through the late 1970s and 1980s is directly responsible for preserving the old-vine Zinfandel plantings that produce the best examples today. When red Zinfandel fell out of fashion, those vines were not grafted over because White Zinfandel kept them commercially viable. Worth knowing when a guest dismisses Zinfandel as a pink wine category.

Zinfandel presents an interesting contrast: it is moderate in tannin but high in acidity and alcohol, which makes it taste bolder than its tannin structure alone would suggest. The flavour profile runs from jammy dark fruit and pepper in warmer-climate examples to spicier, more elegant styles from higher-altitude sites. It pairs well with robust, spiced food: pepperoni pizza, barbecue, charcuterie, spiced lamb. The higher acidity also makes it a useful choice for tomato-based dishes that would flatten a lower-acid red.

Well-made Zinfandel from old vines has the structure to age comparably to Cabernet Sauvignon. Old-vine fruit produces lower yields and more concentrated, structured wines. There is no legal definition of old vine in California, but 40 years is a commonly used threshold among producers. Worth noting on a wine list where old-vine provenance is specified: it signals a meaningfully different style rather than purely a marketing label.

Malolactic fermentation converts sharp malic acid into softer lactic acid, with diacetyl as a byproduct: the compound responsible for the buttery character in many New World Chardonnays. Some winemakers deliberately avoid it to preserve acidity and freshness. Knowing whether a specific wine has undergone malolactic fermentation is useful when a guest says they dislike buttery Chardonnay: the answer is often Chablis, or any unoaked example where malolactic fermentation was blocked.

Chardonnay is a primary component of most Champagnes, alongside Pinot Noir and Pinot Meunier. Blanc de Blancs Champagne is made entirely from Chardonnay, producing a finer, more delicate style than blended Champagnes. This is worth knowing when a guest asks what makes different Champagne styles taste different: grape composition is one of the key variables, alongside ageing and dosage.

"Anything But Chardonnay" was a response to a period in the 1990s when California Chardonnay became stylistically uniform: heavy oak, heavy butter, high alcohol. The backlash was understandable. The catch is that Chablis, white Burgundy, and unoaked Chardonnay from anywhere have nothing in common with that style. A guest who says they dislike Chardonnay has usually had one too many glasses of the 1990s California version. The conversation is worth having before they decline something genuinely interesting.

Sauvignon Blanc's aromatic character is driven by methoxypyrazines and thiols. In cooler climates (Loire Valley: Sancerre, Pouilly-Fumé), methoxypyrazines are retained, producing the characteristic grass, nettle, and cat's paw notes. In warmer climates (Marlborough), they diminish and thiols become more dominant, giving way to gooseberry, passion fruit, and tropical notes. The same compound shift that happens in Cabernet Sauvignon happens here: same grape, radically different expression depending on where it grew.

A reliable rule of thumb: if you would squeeze lemon over a dish, Sauvignon Blanc will work with it. Cold seafood, grilled fish, roasted vegetables, goat's cheese, dishes with fresh herbs. The high acidity is the key: it refreshes the palate and cuts through the fat in richer preparations without fighting the food. Gruyère and any dish built around garlic are also reliable matches. Sauvignon Blanc is also the most effective solution for asparagus, which presents pairing difficulties for most other varieties.

An alias coined in California in the 1960s and popularised by Robert Mondavi. Fumé Blanc is Sauvignon Blanc. The name (fumé means smoke) was intended to give the variety more gravitas in a market that did not yet take Sauvignon Blanc seriously. It sometimes indicates oak ageing, giving the wine smoky, rounder characteristics, but this is not required. Worth knowing when it appears on a list with no further description.

Viognier is a full-bodied white with a distinctively perfumed aromatic profile: apricot, peach, white flowers, and a characteristic floral intensity that can seem sweet even when the wine is completely dry. This sensory disconnect, smelling sweet and tasting dry, is one of the most useful things to explain to a guest encountering it for the first time. It is fruit-forward and aromatic, not sweet.

Viognier is one of the very few white varieties regularly blended with red wine. In the Northern Rhône, it is traditionally co-fermented with Syrah in Côte-Rôtie, where it can make up to 20% of the blend. The addition stabilises the colour and adds aromatic complexity. Guests who notice Viognier listed on a red wine label are not misreading it: it belongs there.

The full body and aromatic intensity of Viognier suit dishes with similar weight and flavour: turkey, chicken, crab, tuna, and spiced food. The floral character is persistent enough to hold its own against complex spice, making it a useful alternative to Gewürztraminer for Asian cuisine. It is underused for this purpose and tends to surprise guests who have not considered it.
