Plexus MRV wine bottle - John Duval Wines



My aim with Plexus MRV is to promot a vibrant expression of fruit aromas from the interaction of the three varieties; and on the palate, to build structure and texture, rather than just acid crispness.

Region:    Barossa

Varieties:  Marsanne 57%, Roussanne 30%, Viognier 13%

Marsanne was sourced from the Marananga and Seppeltsfield region, Roussanne fom the Kalimna region and Viognier from Eden Valley.

Wnemaking:  Gentle pressings were combined with free run juice and cold settled.  Fermenation commenced in stainless steel but some of the Marsanne and Viognier finished fermentaton in and was aged in barrel until bottled in early August.  The remaining Marsanne and the Roussanne was aged on lees in tank until bottling, to enhance the structure and texture of the wine.


Oak Maturation: 50% aged in fine grain French Oak (with only 10% new oak) for 6 months.

Technical Notes:

Alcohol 12.7

pH 3.36

TA 5.8g/l

Vintage: The 2014 vintage did provide some challenges.  After good winter and early spring rains the soil profiles were generally full, but a combination of a windy spring with northern Baross frosts did dramatically reduce the production for some vineyards.  A dry late spring and hot start to summer was brought to a holt on Valentines day by significant rain and then cooler conditions for te remainder of vintage.  Due to the dry, hot January vintage started early with Roussanne on 11th February and Marsanne on he 12th but with the rain on the 14th reds were delayed until the end of February.



Colour: Attractive pale straw

Nose: Aromas of stone fruits, honeysuckle and dried apricot.

Palate: Medium bodied with good texture, dry finish and balaced acidity.  Favours of nectarine, mandarin and pear mke for good food pairings with seafood to white meats.
