Growing your own grapes for wine making has many advantages, both economical and health-wise. By starting grape vines from seed, you are able to eliminate the use of pesticides and other chemicals and control the environment the vines grow in from the time of planting until harvest. Propagating wine grape seeds requires determination and patience however, as grape vines can be very slow to germinate and grow from seeds.
Collect the grape seeds from ripened grapes. Remove all of the pulp with your fingers or under running water. Drop the seeds into a container of water and examine closely. Discard any seeds that float to the top of the water because they are not healthy and will be unlikely to germinate.
Place the grape seeds into a container and cover with peat moss. Add just enough water to dampen the peat moss. Put the container inside the refrigerator for at least three months. Check the seeds often and add enough water to ensure that they remain moist.
Fill small planting containers three-fourths of the way with potting soil. Sow the grape seeds and cover with 1/4 inch potting soil. Water enough to moisten, but not soak the soil. Put the containers in a bright location that maintains daytime temperatures of about 70 degrees Fahrenheit.
Add water whenever the soil no longer sticks to your finger. The seedlings should emerge in three to four weeks.
Transplant the seeds to larger containers when they are 1 to 2 inches tall. Continue to keep the soil moist. The new grape vines will need to remain in the pots for one year before being transplanted outdoors.
