What does dandelion wine symbolize to Douglas and his family?be specific

On the surface, the bottles of dandelion wine represent the summer, & the youthfulness/celebration of life that are associated with that time of year. Each bottle becomes a symbol of the memories of that particular day, which will be brought to life when drunk. The dandelion itself is used as a symbol of life, shown in the fact that they are cut down each summer, but return, fulfilling the cycle. It also represents life in that it is a seemingly unimportant weed and yet it has such tremendous power.
