I get sent an email newsletter from a large chain of HBS. It always provides me with a self righteous giggle as the advice is often pretty shocking. The last newsletter had some "recipes" and at least made an attempt to include OG and exepected FG. Only problem was when you ran the ingredients through Promash the rported OG was completely wrong, a simple mistake that a major HBS chain shouldn't make.
From the latest newsletter I've decided to cut and paste their latest efforts on explaining the complexities of head retention:
"Brewing Tip
Head improverYou will find from time to time that the head on your beer is not that it should be. The usual problem is that the head simply does not last. This is easily fixed by using a head improver which works by making the tiny bubbles in the head stronger, which means they wont burst as quickly. Also ensure that your beer glasses are cleaned with brewers detergent and not regular dishwashing liquid.
