NOTE: With the economy as it is, the HBD is struggling to 
meet its meager operating expenses of approximately $3500
per year. If less than half of those currently directly
subscribed to the HBD sent in a mere $5.00, the HBD would
be able to easily meet its annual expenses, with room to 
spare for next year. Please consider it.

Jeff;
 I think that adding very strong brewed coffee, when bottling, is the best
way.  It should be really strong, and perhaps 1/2 pot or less.

Coffee beans typically are roasted ca 500F and higher - no
worries there.   For the larger distributors,  packaging is
pretty much automated, while the post-roast practices in a
smaller specialty shop might be a little more ... personal.
Ask them.   If you're concerned about your own grinder, just
put the beans in your muslin steeping bag and thump on them
for a while.  Note that "in the secondary" is equivalent to
"in dilute ethanol," so you have some margin of safety.   
Remember that whole beans carry a fair amount of oil, either
on the surface in the darker roasts, or in the interior, so
anticipate some impact on heading.

Subject: Mashtun Insulation

Hiyas,
I am about to brew my first Brew-In-A-Bag batch (British Pale) and thought
some insulation around my brewpot/mashtun to help hold the mash temp
couldn't hurt.
I looked at insulation materials online at the Home Despot (sic) site
and found a Denim Insulation Water Heater Blanket. It has an R-Value
of 6.7 and 48X75 inches.  Seems it is standard to cut this material to
fit your water heater and comes with some tape to stitch the seam.
Seems like a reasonable material to use - no fiberglass to deal with.
Plan is to cut to fit the circumference and height of the pot, and cut
a piece for the pot base and one to drape over the top. Thought I might
also place the pot in a snug-fitting cardboard box for a little bit extra
temp-holding ability.
My questions are-
Has anyone worked with this for poor-boy insulation of brewing equipment?
Is the R-Value adequate in your opinion?
I think I might achieve something
similar if I were to take some R20 to R30 fiberglass insulation and tape
some heavy paper or other "skin" to encase it so I don't have exposed
glass fibers around my wort.
Any thoughts or alternative suggestions appreciated.
Regards,
Mike Morton

Best suggestion I've seen was from Nathan Watkins in the
September/October 2012 issue of Zymurgy. He calls it a Coffee Toddy.
The cold infusion helps prevent bitterness.

Making a Coffee Toddy
For 5 U.S. Gallons (19.83 L) of beer

EQUIPMENT:
1 quart jar with lid, sanitized
2 muslin sacks, or pantyhose

INGREDIENTS:
2 oz. (57 g) of coffee ground to electric percolator (second from
coarsest) setting on commercial coffee grinder.
2 cups (473 ml) water

PROCEDURE:
1. Place ground coffee into the doubled muslin sack or pantyhose
inside jar, then stretch around the outside of the jar.
2. Fill with 1.5 cups (354 ml) cold water and put lid on tightly.
3. Leave in the refrigerator for 24 hours.
4. After 24 hours, open lid and lift out sack of coffee. Pour out the
remaining coffee toddy, leaving the dregs (last coffee bean bits)
behind.
5. Add to secondary before transferring from your primary.
6. If you only have a primary, put the toddy in before bottling, or,
if you keg, the Cornelius keg upon transfer.

Important note: The ideal ratio of coffee to water is 1.0 oz. (28 g)
coffee to 8.0 fluid oz. (237 ml) water.
