From the supermarket to the sublime from £10 to £115
Hennessy X.0 cognac
£89.99, Threshers
This contains everything you would expect from a great cognac. Drink on a cold night by an open fire, it's very moreish. We like this a lot.

Martell Cordon Bleu cognac
£85, Harvey Nichols
My goodness! Pick a flavour and you'll probably find it here, it's a rollercoaster of them. Absolutely phenomenal.

Domaine de la Grolette Borderies Cru cognac très vieille réserve
£29.99, Oddbins
This epitomises cognac for us. An inferno in the mouth. Brilliant and delicious.

Ragnaud Sabourin Grande Champagne cognac premier cru
£86.50, Harrods
This is of excellent quality. It's definitely one of the best tasting we've tried today. It's pure ambrosia in the mouth but the flavour doesn't linger.

Baron de Pibrac armagnac 10 years old
£17.99, Oddbins
Fantastic and smooth. A really interesting spirit. You could almost convince someone that it was tequila or a beautifully aged rum.
4 stars
Hine Reserve cognac
£19.99, Oddbins
Soft and sweet, it feels as though it has been blended really well and invites you back for another go. We like this one a lot.

Rémy Martin Fine champagne cognac VSOP
£29.99, Majestic
This feels good in the mouth. In fact, it makes the mouth water. It's not sticky or oily and it doesn't disappear on the palate.

Maxime Trijol Elegance grande champagne cognac
£25.99, www.nywines.co.uk
It's a little sweet and one- dimensional. A nice product, but could perhaps have been better blended.

Baron de Pibrac VS armagnac
£13.99, Oddbins
Smells of French cheese but that disappears after a few swirls. This is a bit weird - it's unexpectedly soft and silken. But it is tasty, apart from that disconcerting nose.

Waitrose Cognac VSOP
£16.49, Waitrose
Not much flavourful character here but it is a really soft drink. We'd hesitate to serve this as a snifter, but it would go brilliantly with Coke.

Sainsbury's XO cognac, single cru
£19.99, Sainsbury's
There's a hint of pine in a walking-through-a-winter-forest kind of way. Might benefit from a little air in the glass. Hints of pepper, which isn't desirable in a cognac.
2 stars
Rémy Martin X.O Excellent
£115, Fortnum & Mason
Has a peppery style with a controlled and slightly disappointing finish. Not orgasmic but it is moreish.
3 stars
Martell VS cognac
£18.49, Oddbins
This would be brilliant on a Christmas pudding. There's no artificial sweetness to it. Would make a perfect brandy and Coke.
3 stars
Leyrat VSOP cognac
£32 Harvey Nichols
This tastes like a good young cognac but has a slightly one-dimensional scent. It's too light to warrant mixing though, so is a bit of an oddity.
3 stars
Asda extra special 5-year-old brandy XO
£9.98, Asda This is harsh. It's the first brandy we've mixed with Coke that makes Coke taste bad.
1 star
Waitrose 3-year-old French brandy
£9.99, Waitrose This would be useless with Coke as you'd lose what few good fruit flavours it has. Not sure we'd even recommend this for cooking.
