One of the possible culprits for head retention could possibly, maybe, perhaps be lipids in the mash. Maybe. Perhaps. If your filtering technique is inadequate it's possible you are pulling a lot of lipids over which can cause problems with head retention and premature staling post packaging. Using a grant may help reduce lipids from being stripped from the mash.That said, it may not. But it might. Maybe.

So Keith, your positive about this?

I actually do think it can be a potential problem based on my experiences.

Another issue that's easier to check is whether there's residual detergent on your beer glass from a dishwasher machine. Try one glass from dishwasher compared to one that's been rinsed properly under the tap.

Is it possible, at all likely, within reason, perhaps, conceivably, that you could be mistaken.

This has come up, and many of us wash our beer glasses by hand using hot water to repeatedly rinse them. But you're right, this is probably the first place to look when one discovers the problem.

Possibly there is a potential factor of error in my reasoning but perhaps that is unlikely.

I'm 37% sure that I understand 71% of this.

Well, if Keith says it's definitely happening and you're 108% sure he's right, I'm going to start treating my wort with lipase enzymes and conclude that it makes my beers much better.

Nice!

How are these lipids stripped from the mash, what is actually happening or going wrong to cause this if it is potential for problems? You know, if there is by chance any relitivety to the possibility?
