What is that effect? Well, it takes working with a few plants to see it but the berries can be a pinkish color, but not always. Characteristics include a very hard (like a brick) cluster, with discoloration on the sunny side. The discoloration can also be in different parts of the cluster. The bunch stem can be green while others nearby are brown and lignified. The shoot that the clusters grow from can be green and behind nearby shoots (we've noticed some patterns with that here, credit to Jose Castro-Sanchez). The telltale sign of it is when the sugars are testing at around 10-12 brix and the rest of the plants clusters are 19-22 brix. Also the acids are through the roof. When tasted or tested with a refractometer (measures sugar percentage in small juice samples) you can be sure it's water berry. Visually it's more difficult to tell but you can tell with some time working with it in the vineyard. I've included some photos of affected clusters from here.
