The first fruit is wheat (I know this is not technically a fruit, but it considered a fruit at the seder!), representing the good earth and the necessary food it provides us all with each day.
The second glass is ⅔ white wine and ⅓ red wine, because it represents the end of winter and the beginning of spring. The red wine symbolizes the way spring brings color to our surroundings. This glass represents our tradition of plantings trees on Tu B'shevat.
The third glass is ⅓ white wine and ⅔ red wine, representing the continuation of the appearance of spring. Now there is sun and the natural world is coming out again, blooming with colors. However, in the spring there is still rain, which the white wine represents. With this wine we eat grapes, figs, carobs, apples, strawberries, lemons, raspberries, and pears. These fruits all represent creation.
The fourth glass is all red and represents the long-awaited arrival of summer along with the sun, beautiful flowers, ripe fruits, and hot days. This last cup stands for peace for the land of Israel.
