When to toss moss in the sauce?

[Carne de Perro]

Most recipes I've seen say to add Irish Moss at the last 15 min of the boil. One exception is a recipe I just love that says to add the stuff at the beginning of the boil. I never have major chill haze problems w/ this method but was wondering: Am I losing anything by boiling the IM for 60 minutes as opposed to the 15 min method? What difference does the amount of time make?

I've read that boling longer than 15 minutes can lessen it's effects. I stick to 15 minutes.

I use flaked IM not powdered form.

I also re-hydrate mine for about 30 mins.

If expands like 5 or 6 times it's usual size in the glass I use.

Strangely enough, ALL the packages of Irish Moss I've purchased in seven years of brewing say at the beginning of the boil and only a teaspoonful. Who are you going to believe on inflation levels: the auto manufacturer or the tire manufacturer?

I add after the hot break.
