Subject: Black IPA info request

Greetings Beerlings,
A good friend of mine is currently in Portland Oregon
for work & has informed me that Black IPA is an emerging style around those
parts.
He suggested we try brewing one when he gets back.

As I have no real info to go on I would like to enlist your help in
formulating the grain bil.
Should include Roast Barley, Chocolate malt or simply some black malt,
I assume the hopping is as per typical Pacific Northwest IPA.

So many beers so little time.

Regards,

Subject: RE: Getting rid of malt moths

Greg,

I've had bugs in malt before. I can't say what they were but more of a
weevil than a moth. Freezing is what did the trick for me. Here's what I
did. I put the sack of malt into my chest freezer I use for lagering.
But this time on freezing. Left this for a week. I took out the sack and
used a colander to sift the malt, getting rid of a lot of dead bugs, eggs,
flour. The malt wasn't in too bad shape so I put it into gallon ziploc
bags. After a week I put these into the freezer. There will be eggs that
hatch so then freezing killed what hatched and before they were reproducing.
This seemed to work well. When I used the malt I used a bit more to make
up for the bug losses. It made good beer. Up to you to do a protein rest
or not :-)). If the insects have eaten too much of the starch, just toss
the malt.

Good luck,

Dave Houseman

Yes, freezing will help. I used to buy whole grains in bulk from a
health food store and occasionally had a problem with, ahem,
additional protein. Storing the grains in the freezer kept the
insects from reproducing.

You shouldn't need a hermetically sealed container for CO2 to work;
it just has to be reasonably airtight, especially along the bottom
(since CO2 is heavier than air). All you have to do is displace
enough oxygen from the air entrained in the grains to drive it below
the level of viability for the insects.

I can't imagine I'm the first person to run into this problem. How do
I get rid of them? I've been told to fill the containers with carbon
dioxide, but it's not clear how well that will work, especially since
the containers aren't hermetically sealed. Will freezing help?

I respond:

This may (or not) help: In all my containers of various grains (rice,
flour, rolled grains, etc.) I put a few bay leaves. This works to keep
out many critters. It sure can't hurt to try.
