There are three main types of plate boundary: divergent, convergent and transform. Plates move away from one another at divergent boundaries. This happens at mid-ocean ridges. Plates move towards one another at convergent boundaries; one plate is forced below another in a process called subduction.
The skin of a Concord grape is typically dark blue or purple, and often is covered with a lighter-coloured epicuticular wax bloom that can be rubbed off. It is a slip-skin variety, meaning that the skin is easily separated from the fruit. Concord grapes have large seeds and are highly aromatic.
If you want to make a âwhiteâ concord wine out of the red skinned grape, simply press the juice and separate the skins immediately. (The red color is actually in the skin, not the pulp) To make a blush or light red wine, mix the hot water and crushed grapes, then when cooled to around 100Â° F. add the pectic enzyme.
