Sweet and strong wines come into their own at this time of year. So too do UK supermarkets, offering some almost incredible bargains for ports and sherries in particular. Within the groups below, these seasonal recommendations are listed in ascending order of price per cl.

Lustau Dry Oloroso 20% Crazy price for a 12-year-old single-vineyard, hugely appetising wine. Will someone please put Jerez out of its stock surplus and restore prices to what they should be?£5.50 (usually £6.25) for 37.5cl Morrisons

Don Luis Fino del Puerto 16.5% A Waitrose exclusive from Lustau. Much firmer and nuttier on the nose than the average Fino. Stronger, too. There is a ton of character here, with saltiness and breadiness and even perhaps a little butteriness — all you’re missing from this sandwich is the filling. Definitely a bottle worth having for the holiday season. In the same series, Don Gaspar Dry Amontillado and Torre del Oro Palo Cortado are also great value at the same price.£11.99 for 75cl Waitrose

Harveys Signature 12-Year-Old Cream 19% Very different from Harveys Bristol Cream, with real complexity. Dried citrus peel, walnuts and some of those rich spicy flavours you find in Sicilian cannoli. I could well imagine this accompanying the sweet tanginess of Christmas pudding. Just the job, in fact.£11.99 for 50cl (usually £13.99) Waitrose, £14.18 Master of Malt

Lustau, Murillo Pedro Ximénez Sherry 17% This very sweet sherry is too interesting to use simply as something to pour over ice cream. Aged for about 15 years, it’s much gentler and more complex than most PXs. Walnuts might work as a foil for its tooth-rotting nature.£13.99 (usually £16.99) for 50cl Waitrose

González Byass, Una Palma Fino 15.5% Every year a few casks of six-year-old, bready, bone-dry, light sherry are selected for various Palma bottlings. A recent tasting showed that they can develop beautifully in bottle.£14.99 for 50cl Soho Wine Supply, £15.94 Bon Coeur, £15.99 The Oxford Wine Co and many others

Equipo Navazos, La Bota de Manzanilla 101 Florpower MMXVI 15%Imagine electric essence of umami and that’s what this delicate, dry sherry is like. I Think Manzanilla 2018 (£13.90 for 37.5cl) is its baby brother.£36 The Sampler

See also my recommendations published on September 19. All of these will last forever in an opened bottle.

Barbeito Boal Reserva 19% Pale, orange and medium-sweet. Pungent, somehow intensely mineral nose and extremely elegant. Yes, it’s sweet enough to drink after a meal but it’s actually quite delicate and I can imagine enjoying it at almost any time. A wine lover’s madeira . . .£13-£15 for 50cl Fareham Wine Cellar, Lea & Sandeman and many other independents

Henriques & Henriques 10-Year-Old Sercial 20% You could drink this before or with a meal. It would be magical with a clear soup or bouillon. Super-clean, pure and revitalising. Much lighter and drier than any Bual or Malmsey.£19.99 for 50cl Waitrose, The Wine Society and others

Graham’s 10-Year-Old Tawny 20% This pale tawny comes in a particularly smart stoppered flask. It’s pretty sweet but has good tanginess and freshness too. Some nuttiness, as well as dried-fruit notes. It would be great with cheese.£15.35 (usually £20.49) for 75cl Waitrose

Quinta do Noval 10-Year-Old Tawny 19.5% More youthful and concentrated than the super-smooth Graham’s, with lots of pungency, some fine tannin and a treacly note. It will probably last longer in an opened bottle than the Graham’s and it is slightly less sweet. This would go well with Christmas pudding. £19.99 (usually £24.99) for 75cl Waitrose

Quinta do Noval Late Bottled Vintage 2013 19.5% Baby vintage port at a great price. Luscious and very well balanced, this is a pretty smart wine worth decanting. It’s much more expensive than most late-bottled vintage ports but it deserves to be. Sip contemplatively with Stichelton. £23.99 for 75cl Cambridge Wine Merchants, Amazon

Taylor’s, Quinta de Vargellas 2005 20.5%/2008 20% I couldn’t extract the 2008 cork so it had to be pushed down into the bottle before decanting, and the luscious 2005 was only marginally better. Both vintages are heady with herbs, autumn undergrowth and the lightest of tannic frameworks. Serious wine at a great price. No hurry to drink the 2008. £25.59 (usually £31.99) Waitrose

Sandeman 20-Year-Old Tawny 20%Perhaps not as complex as the slightly cerebral Noval 10-year-old but this would not disappoint anyone looking for a super-smooth, light, long-wood-matured port — if they can ignore the lurid new packaging. Decant?£31.99 (usually £39.99) for 75cl Waitrose

Warre’s 2000 20%Probably the youngest (and cheapest) vintage that vintage port enthusiasts could think of broaching. This especially luscious one has consistently shown well. £47.99 Sandhams and other independents

Taylor’s Quinta de Vargellas Vinha Velha 2011Extraordinary wine likely to appeal to port lovers throughout its long, wild life. £310 for 75cl Nemo Wine Cellars and fine wine traders

Lustau Moscatel de Alejandría, Andalucía 15% This screwcapped Muscat from a vineyard near Cádiz has some real character to it. Exceptionally well made for a sweet wine at the price. Like a Golden Shred marmalade cordial. £4.99 (usually £6.49) for 50cl Waitrose

Ch Filhot L’Or du Ciron 2010 Sauternes 13% A pretty good price for a 10-year-old wine showing some evidence of noble rot. Not the richest nor most complex Sauternes but a useful half-bottle for any festive household. £12.50 for 37.5cl M&S

Berry Bros & Rudd 2017 Sauternes 14%True, typical pear-juice notes from the irreproachable Ch Climens. Just a bit lighter overall than the real thing. Another useful half-bottle.£14.95 for 37.5cl Berry Bros & Rudd

Ch Pierre-Bise, L’Anclaie 2014 Coteaux du Layon Beaulieu 11%An old favourite from Anjou. Deep bronzy-gold, with a toasty, pungent nose that is more expressive of Chenin than of sweet wine. Then on the palate there is a lovely satin-swoosh of very sweet, buttery tarte tatin juice and just enough acidity. Really quite vibrant and beautifully composed. You could happily sit and sip this on its own, as it finishes reasonably dry, but it would also go well with fruit and creamy desserts. Very well done.£17.95 for 50cl Lea & Sandeman

Ch Raymond Lafon 2009 Sauternes 13.5%Unspittable — I wrote that when tasting this wine professionally en primeur. It’s all dried apricots, with the intensity and richness of noble rot. It should be great now. Try with Roquefort for a special treat?£36.90 for 75cl Four Walls

Royal Tokaji Gold Label 6 Puttonyos 2016 Tokaj 10.5% The top selection from this producer smells of smoked apricots and tastes of particularly ethereal prune juice. Whistle-clean and so refreshing it could be drunk on its own as an aperitif. Delicacy is the keynote. So much flavour, so little alcohol.£40 for 50cl Majestic

Ch Suduiraut 2001 Sauternes 14%This is creamy, opulent and already complex, and it obviously has a long way to go too. Barley sugar at its best. £43.20 for 37.5cl Four Walls

Martinez 5 Anni Riserva Dolce Marsala, Sicily 18% More than an ingredient, this is a medium-sweet drink to sip on its own or with all those sweet Christmassy things that are long on dried fruit. Good value.£9 for 37.5cl M&S

Dom Bousquet, Dulce Malbec 2018 Tupungato, Argentina 19.5% Certified organic grapes are grown at 1,200m to produce an unusual, pure, berry-flavoured, port-like drink that would go particularly well with high-quality chocolate. £14.95 for 50cl Davy’s Wine Merchants

Les Vignerons de Maury, Solera 1928, Cask 873 Maury, Roussillon 17% Red Grenache long aged in oak in the far south-west of France, where this is the traditional wine style. Great value.£19.95 for 50cl Berry Bros & Rudd
