Winter 2016 was exceptionally mild and very rainy. Mild temperatures and soaked soils provoked early, balanced budburst. A cold, rainy spring slowed down the growth of the already well-advanced vines. The weather turned out to be exceptional during the flowering period: perfect fertilisation of flowers, no shatter or shot berries.
A hot, dry summer contributed to maintaining slight water stress. Grapes were then able to mature in ideal conditions. Summery temperatures and rare beneficial rains gave very concentrated grapes, with tannins of high quality at maturity, particularly for Cabernet-Sauvignon, which is generally late maturing on the estate.
Wines revealed fine acidity and a high tannic load. Maceration times were fairly long, in order to extract all the best quality tannins. The long extraction was composed of pumping over 3 to 4 times per day, accompanied by some cap punching.
From the vine to the glass
Harvest began on September 22nd with Merlot grapes on gravelly-loamy soils: the earliest soils on the estate.
Following malolactic fermentation in tanks, wines were partly barrel-matured, with 15% new barrels, bringing complexity and roundness to this Château Mirefleurs wine.
