(Wine-Searcher) - The release of a string of exquisite wines brings the buzz back to the en primeur campaign.

A "drop-dead gorgeous" Léoville Barton, a "best since 1961" Giscours and an excellent but disappointingly scarce Pontet-Canet are at the head of a clutch of recent 2015 Bordeaux releases.

Château Léoville Barton, the much-loved Saint-Julien second growth, is on the market for £575 ($841.40) a case, a good deal more expensive than last year, but praised to the skies by almost every major critic.

The Wine Advocate's Neal Martin called it "drop-dead gorgeous", American critic Antonio Galloni said it was "class personified", and it was one of this reporter's wines of the vintage.

Merchants are excited too – London's BI (formerly known as Bordeaux Index), fired off an email to its customers the moment the price came out on Thursday morning, telling them Léoville is "undoubtedly … their finest wine since the monolithic 2010. Always a textbook Saint-Julien, packed with classical blackcurrant and blackberry fruit, gravel and cedar, 2015 has delivered a precise and clean-lined Barton."

Giscours, another hugely popular property, is €36 ($40.30) per bottle ex-negociant, up 30 per cent on the 2014, and £390 ($570.60) per case on the London market. The Margaux third growth attracted very high scores across the board, with Martin suggesting the 2015 is the "best since 1961".
