The whey I've been using for months is usually light and airy (flour like), mixes easily, and has always tasted the same.
In the last tub the powder was a bit more coarse (table salt like), didn't mix quite as well, and tasted a little different, but it didn't taste so off you'd assume the stuff was bad if you'd never had the previous tubs.
Does whey powder vary slightly in consistency from batch to batch or is this a bad batch?
I always buy the same cheddar cheese and the color varies slightly ever time. Does whey powder also have the same sort of variation?
If it's bad would you blame the company (using cheaper ingredients) or the shipper (sat in a hot truck too long)?
If I switch brands (current brand is Ultimate Nutrition) does anyone have a favorite micro/cold filtered whey protein isolate?
