What is the biggest benefit of Riesling’s high acidity?
It balances both ripeness and high levels of sweetness (residual sugar).
Describe the different fruit profiles found in just-ripe Riesling vs. extra-ripe Riesling.

• Green apples
• Green pears
• Sour citrus (lemon, lime)
Extra-ripe
• Stone fruits (peach, apricot)

• Dried fruits (golden raisins
Name 2 ways that off-dry or medium style Rieslings get their sweetness.
- Interrupting fermentation and filtering/removing yeast, leaving the wine with some residual sugar
- Adding sterile grape juice (Süssreserve) after fermentation
What is Süssreserve?
Sterile, naturally sweet grape juice
How do the sweetest styles of Riesling retain their sugar?
Fermentation stops naturally in the sweetest styles of Riesling.
There is too much sugar for the yeasts to eat.
Why do winemakers typically ferment Riesling in stainless steel, or other inert vessels, rather than oak?
Stainless steel helps Riesling retain those hallmark fruit and floral aromas and flavors.
Name some tertiary flavors that aged Riesling can develop.
- Honey
* Petrol (gasoline/Vasoline)
Which region will have the lightest-bodied Rieslings and why?:
- Mosel
