Grillo: Sicilian whites and use of lees
From fresh white wines to those in contact with lees. Compare the post-fermentation processes using the same Grillo.
Questions for this course
Can the weight of Grillo be explained by variety alone?
Before you start reading, briefly jot down your thoughts. You will rephrase them at the end.

Used for both single-varietal and blends.
Grillo is a white variety from Sicily. Sicilia DOC introduces both single-variety wines and blends with Chardonnay or Lucido. Even for wines prominently labeled “Grillo,” confirm the grape composition before starting a comparison.
Fermentation temperature and aroma.
A style made with gentle pressing and low-temperature fermentation is introduced as having aromas reminiscent of grass and grapefruit. This is an explanation involving the process. Avoid assuming all Grillo has the same aroma just by seeing the variety name.
Compare contact with the lees.
The same source explains that contact with lees produces a more textured style. Use of lees and use of barrels should be confirmed separately. Do not assume that thickness means barrel aging; return to the product data to check time in each vessel and on lees.

Grillo source analysis: Sicilian whites and use of lees
This comparative material is based on sources. Please distinguish between the characteristics of grape varieties and the conditions of each region or product as you read.
The table is a summary of the sources below. Values given with product names or vintages are based on data for those specific items.
| Comparison items | Winemaking featuring low-temperature fermentation. | Production that highlights contact with the lees. |
|---|---|---|
| Raw material | Grillo | Grillo |
| Points of attention in the process | Pressing and fermentation temperature. | Contact with lees after fermentation. |
| Missing conditions | Container / blend / harvest year | Lees duration, container, blend |

What is the relationship between low-temperature fermentation and lees contact?
Fermentation temperature and post-fermentation lees treatment are separate factors. Avoid reading the two rows as mutually exclusive classifications.
What uses of Grillo are introduced in the materials?
The materials read here show multiple methods for making whites. They cannot be fixed to a single use.
If it’s a full-bodied white, is barrel used?
Contact with the lees also affects mouthfeel. Don’t assume the vessel based solely on mouthfeel—confirm with product details.

Explain in your own words
Compare winemaking featuring low-temperature fermentation with that featuring lees contact, and describe the conditions they share and those that differ.
