Pressing Matters

⦿ Planted in 2002, Tea Tree, Coal River Valley

⦿ Pinot Noir 3.7Ha and Riesling 2.9Ha

⦿ 4 clones of Riesling

⦿ 6 clones of Pinot Noir across 4 different roots

● 20 different combinations

⦿ Vine density 4,300-5000 vines per Ha, 2m rows, VSP

⦿ Riesling made at Winemaking Tasmania

⦿ Pinot Noir made on site

⦿ Entered 21 Wine shows and won 26 trophies








Conclude

Pressing Matters

⦿ Viticultural management

⦿ Irrigation - water balance

● Maintain balance to fruit set, RDI fruit set to veraison, maintain

veraison to post harvest

● Water was limited

⦿ Fertiliser - added based on petiole/soil analysis, broadcast and

fertigation

⦿ Leaf plucking on morningside of vine (not 2014)








Conclude

Pinot Forum

⦿ Replicated Clonal Trial Block

⦿ Planted 2004-2006

⦿ Aim

● Assess the performance of new clone and rootstock

combinations in different Tasmanian climates and soils (4

sites?)

● Provide a source of Class A mother vines for Pinot Forum

Members

⦿ To date all fruit from the Trial block has been picked and made into

one batch of Pressing Matters Pinot Noir

⦿ No formal research yet

History of Clonal Selection

⦿ Began in the 1950’s

⦿ Wadenswil, FPS/UCD, Burgundy, Colmar, Geisenheim,

CSIRO/Merbein

⦿ Aim was to provide planting material of one clone with known

characteristics

⦿ Match the clone to the growing conditions

Discussion








Conclusion

⦿ Rootstocks can create diversity in wine characteristics, just like

clones

⦿ Choice of rootstock can influence maturity and yield







Conclude

Conclusion

“This trend towards clonal selection has seen some

criticism from wine writers and viticulturalists who

complain about "mono-clonal" viticulture that has the

risk of producing wines that are overly similar and dull.”

(WSET, "Wine and Spirits: Understanding Wine Quality", 2012)
