Wine Glass Fill Level Guide - Visual Reference for Serving Sizes #3806002 (License: Personal Use)

This minimalist black-and-white line drawing depicts a classic stemmed wine glass with two horizontal reference lines inside the bowl: one near the midpoint and another closer to the rim. The design emphasizes clarity and utility, making it ideal for educational or instructional content about wine service standards. No liquid is shown, allowing users to visualize portion control for different wine types.

Used on wine education sites, sommelier training materials, bar management guides, or restaurant staff manuals to illustrate recommended pour volumes (e.g., 5 oz for standard servings, 3-4 oz for tasting flights). Matches user intent for learning proper wine etiquette, portioning, or inventory control.
