Sulfur Residues and Post-bottling Formation of Hydrogen Sulfide
Have you ever had wine go into the bottle smelling sublime, only to emerge later on smelling strange? Graduate student Jillian Jastrzembski and Gavin Sacks, associate professor of food science, explain what can cause this, and how to reduce the risk of these off-aromas in finished wines.

Comparing Red Wine Color in V. Vinifera and Hybrid Cultivars
In V. vinifera wines, the color transition from purple-red to brick red during aging is well documented. This transition, driven by anthrocyanins, has not been documented in hybrid varieties. Claire Burtch and Anna Katharine Mansfield discuss what is known about wine color and hybrid wine composition.

GRAPES 101

How Grapevines Respond to Water Stress
Leaf stomata open and close to regulate water vapor and CO2 exchange. When drought stress causes closure, photosynthesis and evaporative cooling stops. Prolonged deficits cause leaf senescence, ripening delays, and carryover effects. 


BRIEFS
