How to choose the proper shape and size? There are distinct differences in shape and size depending on whether they are designed for white wine or red wine. For white wine, the glasses typically have a smaller bowl and a narrower opening to preserve the delicate aromas and maintain a cooler temperature. Red wine glasses, on the other hand, have larger bowls and wider openings to allow for better aeration and enhance the bold flavours and aromas of the wine. So, whether you’re sipping on a crisp white or a full-bodied red, the right wine glass can truly elevate your tasting experience.
