be able to easily meet its annual expenses, with room to 
spare for next year. Please consider it.

Subject: Hop Aroma

Hop aroma (and flavor) come from the essential oils. Putting hop flowers 
in a hammer mill and then compressing the powder into pellets has got to 
have a detrimental effect on these volatile oils. Thus I'd offer that 
the first step in obtaining aroma/flavor is to use at least some portion 
of leaf hops. These seem to be getting harder and harder to get. 
Obviously packaging in the small quantities that home brewers buy and 
doing it for a couple dozen varieties has got to be easier with pellets 
than leaf and the wholesalers seem to be going that way.

Second factor is heat which drives off the essential oils so to maximize 
aroma and flavor one needs to minimize heat. Dry hopping is obviously 
one way to go. Late kettle additions (even right at knockout) is another.

Seems to me that the ultimate way to get lots of aroma and flavor is not 
to use hops at all but rather their extracted essential oils. One way to 
get these is by steam distillation of a quantity of hops. This you can 
do yourself but it does take some equipment and know how (not much of 
the latter). Or you can buy the essential oils of several varieties from 
the larger HB suppliers. Adding essential oils to the beer will give you 
much more flavor and aroma than you can reasonably expect to get from 
flowers and/or pellets. Some interesting beers result.

For hop aroma you want to add the hops during the last 10 minutes (or less)
of the boil. Obviously, bigger batches need more hops. Two ounces (57 grams)
at ten minutes should be good.

Good luck!
