READ THE DIAGRAM
Consider aspect and light on slopes along the river bank.
Selecting an item will highlight and compare the corresponding section.
A schematic diagram of the relationship between slopes and rivers. This is not the measured shape of Calmont or a diagram showing sunlight from a specific orientation. To the supporting reference ↓
FIELD NOTE 01
River names and winegrowing regions
Mosel’s wine region includes not only the banks of the Mosel River, but also the valleys of the Saar and Ruwer. On maps, distinguish the central area around Bernkastel, the terraced vineyards downstream, and the upper reaches.
Steep slopes and terraced vineyards are not only landscape features but also a starting point for considering viticulture practices. You cannot always use the same machinery as on flat land, so understand the direction of the slope and different work methods separately.
FIELD NOTE 02
Do not restrict to Riesling only
The primary variety is Riesling, but Müller-Thurgau and Elbling also appear. Even in regions with a strong image of white wines, Spätburgunder is present.
Check village names, vineyard names, dry indicators, and Prädikats alongside grape variety. Don’t assume all Mosel wines are low alcohol and sweet just based on the name. Even if the origin is the same, fermentation approach and residual sugar alter the comparison criteria.
FIELD NOTE 03
Standardize sweetness/dryness in comparisons.
When comparing Rieslings from Rheingau, first either match them both in dryness or check residual sugar information. Do not simply compare Kabinett and GG and attribute all differences to river or soil.
By recording the location, vintage, residual sugar, and alcohol of vineyards separately, you can see which conditions are shared and what is different. Use the overview of the region to generate questions, and verify with specific bottles for reference.
FIELD NOTE 04
Refine the locations to Mosel, Saar, and Ruwer.
The Mosel appellation includes not only vineyards along the Mosel River, but also those in the valleys of its tributaries, the Saar and Ruwer. Even if you start with the commonality of being along the river, once you consider tributaries, slope orientation, and the openness of the valleys, you see that the vineyards do not all share the same conditions.
DWI's regional overviews show not only the steep slopes but also the diversity of varieties including Elbling. It’s necessary to read about regions, varieties, and final wine style (dry or sweet) separately, rather than locking Mosel into the single image of 'slate Riesling sweet wines.'

FIELD NOTE 05
Consider the sun-exposed aspect from Calmont
Calmont, between Bremm and Ediger-Eller, is a concrete example for considering steep slopes. The DWI explains the relationship between slopes and sunlight. In schematic diagrams, confirm not only the river's position, but also which way the vineyards are oriented.
A steep slope and long sunlight exposure are not the same. By examining orientation, surrounding mountain shadows, and the canopy, you can connect the description of the terrain to the sunlight the actual grape clusters and leaves receive.

FIELD NOTE 06
Matching sweet and dry styles from the same vineyard
Even when comparing Rieslings from the same vineyard and vintage, mixing dry and off-dry types introduces variables beyond just the site. Start by checking sugar, acidity, and alcohol, then move on to grape selection at harvest and fermentation decisions. It’s important not to attribute the impression of acidity in tasting solely to vineyard features or soil effects.

Check sweetness/dryness level and vintage, and if possible, compare residual sugar, alcohol, and maturation as well.
PAUSE & REFLECT
