Richard was asking in #198 about freeze sheild. I have not used this product
but a person at Alternative Beverages told me that it was glycerine, which
is what I use for freezing cultures. I get pint bottles at the pharmacy,
which is much cheaper than the little bottles, ask for it behind the counter.
The special issue of Zymurgy (out next) will have a bunch of stuff on yeast
in it.

Cher, in #199 was wondering about 'scum' in the "Cherries in the Snow" brew.
Being perverse, I would call it "cherries in the scum" :-) to see if my friends
would drink it! I have used various fruits but have not had a persistant
foam/scum residue. I would suggest tasting it. If it clears up as you stated
it was doing, and has a good palate, then its ok. Contamination is usually
visible or detectable via odor or taste. No pathogens can live in beer, it may
taste so bad you cannot drink it but it won't be fatal. I judged barley wines
at the second round AHA conference, and one of the bottles actually had mold
growing on the surface of it! (blech), we decided to judge it anyway. It sounds
like your pasteurization process was ok, I generally smash my fruit (macerate)
before adding it to maximize liberation of the sugars. If you get pectin haze
you can try adding a little pectic enzyme.

Paul, in issue #194 comments on how a brewery in England uses hop pellets, for
ease of manipulation. I am sure they produce an excellent product. I adhere
to my view that for homebrewers, hop flowers are the best. I have no problem
examining the flowers, and will not hesitate to return them if they are not in
peak condition. I have had pellets that seemed ok, but upon boiling, a LOT of
woody/stalky pulp showed up, it was too late at that point, and bitterness was
not what it should have been. I feel its very evident when flowers are fresh,
but not so much when in pellet form. Pardon my bitterness :-), but would an
American business person tend to take the most beautiful hop flowers and smash
them into pellets? Home brewers don't have the clout that a brewery has, in
terms of demanding a consistant fresh product. I purchase pellets when I have
to, but I get consistantly better results with hop flowers.
