While it is safe to chill glassware briefly in a refrigerator or with ice, freezing to subzero temperatures is not recommended. For cocktails or beer, chilling (not freezing) is enough to enhance taste without risking breakage.

Here are some best practices for chilling glassware:

• Chill in a refrigerator
• Use tempered glass or metal cups
• Cool the drink itself, not the glass

What to avoid:

• Pouring warm drinks into frozen glasses
• Using thin or decorative glass in a freezer
• Rinsing frozen glass with warm water

What can happen if glasses are not chilled responsibly:

• Thermal stress and fracturing
• Increased Brittleness
• Condensation Issues
• Etching or Frost Damage
• Risk of injury
  • Hands can stick to condensation or frost on the surface
  • Sudden breaks could cause cuts or lacerations to hands and fingers
