can whey powder have a gritty or dry unpleasant taste and texture?

Does whey protein have a gritty or unpleasant taste like some other protein powders?

Whey protein has a clean, neutral favor. When used in food manufacturing, it adds little or no taste. Whey protein dissolves easily in liquids and does not have a gritty mouth feel, texture or taste.

So if you find yourself asking that question, it might be because you have bought a poor quality product, or there are too many other fillers and ingredients in your whey powder, like some mass gainers can have lots of other things in them besides the whey powder.
