Bumpy leaves on grape vine

My grape vine leaves are developing bumpy blister-like things. Any idea what these are or what I should do about it?

I suspected some type of gall and found the following explanatory website:

I googled in 'blisters on grape leaves'. There are several insects that can do this, and they are listed down in the article with an army of other insect pests.
