Pedro Ximénez Sherry
Inky, syrupy sweet sherry made from sun-dried Pedro Ximénez grapes, with residual sugar from 250 grams per litre upwards.
What PX is
Pedro Ximénez sherry, or PX, is the darkest, sweetest and densest wine in the sherry catalogue. It is made from the Pedro Ximénez grape, not Palomino. After harvest the grapes lie on esparto mats in the open sun for one to three weeks, a practice known as asoleo, which collapses water and concentrates sugar. The resulting wine sits closer to syrup than to wine, often carrying 350 to 500 grams of residual sugar per litre.
Colour runs deep mahogany to black. The aroma builds in layers: raisin, fig, espresso, dark chocolate, old-fashioned liquorice, sometimes a balsamic edge after long ageing.
How PX is made
The sun-dried grapes press into a thick, sugar-saturated must. Yeasts give up around nine percent alcohol because the osmotic pressure shuts them down. The cellar master fortifies with grape spirit to roughly seventeen percent, which stops fermentation permanently. What remains is partly fermented sweet must with alcohol locked in.
The wine then ages oxidatively for years or decades in a dedicated PX solera. Because high sugar slows evaporation, the volume losses are gentler than in oloroso, but the wine still gains weight and complexity over time. VOS PX is at least twenty years old on average, VORS at least thirty.
Where the category gets misread
The common assumption is that PX is purely a pudding wine and stops there. That undersells it. PX works as a topping for vanilla ice cream, a deglaze in a game sauce, a sweet note in vinaigrettes for roast winter vegetables, or a cocktail modifier with mezcal and dark coffee. Modern London bartenders have used PX as a substitute for syrups for at least a decade.
A second confusion is that all PX tastes the same because sugar dominates the first sip. The opposite is true. A ten-year PX and a thirty-year VORS share the residual sugar but diverge in complexity as widely as a young ruby port and a Colheita tawny.
How to serve it
Thirteen to sixteen degrees Celsius, in a small white wine or digestif glass. Pair with blue cheese, roasted nuts, dark chocolate, or pour a spoonful over good ice cream. An open bottle keeps six months to a year because the sugar acts as a preservative.
