Red wine glasses are easily identified by their bowl shape. They are often the largest type of wine glass because the larger bowl enhances the bouquet and flavor of red wines. Considering how large the bowl is, you shouldn’t fill the glass more than 1/3 full. Red wine glasses can be broken down into two sub-categories based upon how tapered the rim of the glass is compared to the bowl. Shot with a Canon 5d mkIV. One Eiinstein light gelled with purple.
