FIELD NOTE 01
Rivers and mountains
Vineyards are found along the tributaries of the Nahe, such as the Glan and Alsenz. Confirm its position protected by the Hunsrück Mountains and use a map to check its distance from Mosel and Rheingau.
Rather than just searching for soils with similar names, first check if they are on the same slope and how the height differs from the river. Vineyard conditions involve multiple factors, so don’t directly apply a region’s overall description to a specific plot.
FIELD NOTE 02
Schist, volcanic rock, loess.
DWI cites schist, volcanic porphyry, loess, and loam as regional diversities. These are clues to researching vineyards, but you cannot determine aromas from rock names alone.
Riesling is important for whites, and Burgundy-type varieties also appear. If selecting two Rieslings, compare vineyard, sweetness/dryness, and maturation while keeping the grape consistent.
FIELD NOTE 03
Make the comparison notes two-tiered
Write vineyards and base materials on the upper row and winemaking details on the lower row. The upper row should include village, vineyard, slope, and geology; the lower row should include residual sugar, vessel, and maturation period. Any unpublished information can be left blank.
If you later add your sensory impressions, you can distinguish between what’s evident in the documentation and what you perceived while tasting. Avoid making simplistic claims like “this aroma is because it’s volcanic” and instead collect more material for analysis.
Vineyard location, sweetness/dryness, fermentation and maturation may all differ. Record soil type as one comparison item.
PAUSE & REFLECT
Check your understanding.
With two Rieslings from different soils, can you attribute the difference in taste solely to soil?

Write in your own words
Write what you have learned, your reasoning, and what you still need to confirm.
