FIELD NOTE 01
Multiple grape varieties planted in the same vineyard
For Wiener Gemischter Satz DAC, at least three eligible grape varieties must be co-planted in the vineyard, and harvested and vinified together. No single variety can exceed 50%, and the third most-planted variety must be at least 10%.
You cannot display this simply by blending three finished wines. It is important to combine the varieties already in the vineyard and proceed directly to harvest and vinification.
FIELD NOTE 02
Judgement of harvest date changes
Even if maturing speeds differ by variety, collaborative harvesting requires sharing the decision on harvest dates. The key difference from harvesting and fermenting separately, only blending later, is the point at which adjustment is possible.
This does not mean one side is always superior. By comparing where decisions are made—vineyard, harvest, or post-fermentation—you can understand field blends and co-fermentation as processes.
FIELD NOTE 03
A single wine is not always from a single vineyard
Gebietswein may use grapes from several qualifying vineyards. Do not confuse the existence of co-planting requirements in each vineyard with the idea that each bottle can only come from a single vineyard.
Vienna’s appellation system includes the levels of region, village, and vineyard. Before discussing the geographical scope, check for indications of the vineyard on the label. The use of field blends alone does not define the geographical boundaries.
FIELD NOTE 04
List and compare the two processes
In the exercise, draw arrows for "field blend → co-harvest → co-fermentation" and "harvest separately → ferment separately → blend after completion." Explain where the variety composition is determined and where it can be changed.
Fulfilling conditions for origin or number of varieties and the harmony you perceive are separate judgments. Do not back-calculate legal requirements from tasting impressions; check using the label and technical materials.
That alone is not enough. There are requirements such as co-planting, grape composition, and joint harvesting/vinification in the vineyard concerned.
PAUSE & REFLECT
Check your understanding.
If you blend the completed wines from all three varieties after fermentation, does this become this DAC?
