Berton Reserve Shiraz 2015 - August 2017 Decanter review
For those unable or unwilling to wait, Exel discussed the relative merits of the 2014 and 2015 vintages with Berton owner, Bob Berton, in person, a few weeks ago at the London Wine Fair. It is Bob's view that the 2014 is the equal of the 2015 but was simply not submitted for review at the previous DWWAs.
The Reserve Shiraz is deepest dark red with a very youthful and vibrant garnet hue. The aromas are powerful and complex with a wealth of fruit ranging from ripe black cherries and blackberries with hints of eucalypt and spice. The rich and full palate displays soft flavours of plum skin, mulberry and hints of vanilla and blackberry, These abundant flavours are underpinned by fine vanilla from the oak and defined by exciting spicy tannins.
