The 2014 vintage was awarded a Platinum Medal, 98 points and Best in Show status at the 2018 Decanter World Wine Awards (click link for details). That said, the 2015, from an amazing harvest, has all the hallmarks of the great 2014 and has just yet to be rated!

Poggio Al Tesoro Il Seggio Bolgheri 2015 - fiche technique
One of the most exciting estates to have emerged from Italy in recent years, Poggio al Tesoro is a 70-hectare property in Bolgheri acquired in 2002 by the Allegrini family. The first vineyard they bought, Le Sondraia, is next door to Ornellaia and was previously rented by them. It is 12 hectares in size and is planted with Merlot, Cabernet Franc and a small amount of Cabernet Sauvignon.
‘Seggio’ is the name of the creek that runs through Bolgheri - its course from above is represented on the label. This wine is produced from different plots of vineyards in the Poggio al Tesoro estate. The Cabernet Sauvignon is grown in the Via Bolgherese vineyards, at 53 meters above sea level. Here soils are deep, with coarse-grained red sand, that is gravelly and well-drained with a layer of clay at 120 centimetre below the surface. The other varieties are grown on the Le Sondraia vineyard, at 35 meters above sea level. Its soils are clayey with well-drained sandy silt and high concentrations of magnesium and iron. The average age of the vines is 17 years and they are spur-pruned and cordon-trained.
The 2015 harvest: Ample water was available following a very wet winter allowing the vines to bud and flower until early June and ideal summer conditions ensured all subsequent phenological stages: from fruit set to maturity, developed evenly. A hot July was mitigated by timely thunderstorms, while a sunny, breezy August allowed the grapes to reach a perfect phenolic ripeness before harvest commenced on the 31st August. 2015 may be considered one of Bolgheri’s great vintages with wines exhibiting balance, great structure and intense aromatics.
40% Merlot, 30% Cabernet Sauvignon, 20% Cabernet Franc, 10% Petit Verdot. The grapes were destemmed and softly pressed. Fermentation took place in temperature-controlled stainless steel tanks at 28-30°C for 12 days. Malolactic fermentation was carried out naturally in barriques in November. The wine was then aged for 15 months in 225 litre French oak barriques from Allier (30% new, 70% second use).
This wine has an intense ruby red colour, and there are red berry and cassis aromas with mineral and spicy notes on the nose. The palate is medium bodiedand the tannins are elegant and silky. The wine has a lively finish.
