Subject: Forced air lines

For forced air cooling of beer lines, depending on the
geometry of your setup, you might be able to use what
my friend Lou King set up in his place:

Use a stretch of 3 or 4" diameter pipe (e.g. PVC), and 
inside that pipe have another, smaller one that has the 
beer line running inside of it.  A cheap PC fan can be 
used to force cool air through the small pipe, thus chilling 
the beer line to roughly the same temp as your fridge, and 
the return comes back outside of that smaller pipe,
inside/via the big one.

If you have it sealed well, you should encounter no 
problems with condensation or moisture inside, especially
if you use something like Damp Rid in the main cooler.
You could consider insulating it all on the outside.  
That would reduce the energy usage a tad as well, 
since any heat the air picks up from the exterior shell 
as it returns to the cooler (as well as the heat from
the fan) will go back to the fridge.

For a more flexible setup, you might look at dryer flex
hose, but I think that would surely call for insulation
around it.  You might consider something like this
flexible, insulated hose:

Then just run a smaller flexy "air-out" line inside it
and the beer line inside of that.

Subject: re: fruiting the Frambois

Thanks, Jeff. I have more questions. I've never used Potassium sorbate 
in beer, only wine: Will it leave any flavor?? How much Pot. sorb. per 
gallon will work? What is the procedure as far as time before adding th 
fruit?
Thanks, Joe
