Who makes communion wine?

Any wine manufacturer can make communion wine.

There is no liturgical requirement for Communion Wine to be made a certain way of by a certain vineyard. However, there are many wine manufacturers that specialize in bottling "Communion" wine. Some Christian churches even use Grape Juice rather than wine.

Each pastor can choose the style and taste of the wine that they use in communion. some choose a red whine, other white, some are sweet while others are dry.
