This was just posted on the Craftbrewer digest. Some of you who have bought Powell's malts may be in a position to participate:

G'Day All

Firstly please pass this on to other digests if you can. I need as much
involvement as possible.

With the continuing saga of Powell's malt (Some say its ok, some say its
not) - I always wonder if the problem is to do with consistancy from batch
to batch.

Now doing the radio program http://radio.craftbrewer.org ,it does allow me
some perks, as I do get to talk to some very interesting fellows in the beer
business, and that includes some serious researchers. It was during a talk
with one such fellow that this topic came up. Well some wheeling and dealing
later, and suddenly we (Australian craftbrewers), will have access to some
very expensive laboratory equipment.

I have managed to arrange for a little experiment, where the leading malt
researcher in this country is prepared to do A FULL analysis of a malt for
us. That includes the concentration of all the enzymes, protein conversion
etc, and give that to us. This is an extremely rare treat, and no better
subject to test this than Powells Malt.

Simply put, I can organise to get Powells malt tested and determine if the
performance issues is due to malting, or the brewers method, and more
importantly, where the fault lies.

So what do I need.

1. 20 brewers arround the country who have used Powells malt, and still have
some in stock.
2. these brewers will need to mail only 20 grams to Tasmania. Should be
under $1.00 postage.
3. your normal brewing efficiency with other malts and what you are getting
with Powells malt.

This is a rare opportunity. Can the word be passed arround quickly, as I
need 20 samples. That not only includes people who are getting poor
performance, but also those who are getting excellent performance.

If people can contact me at either

craftbrewer at bigpond dot com
or
grahamsanders at rawnet dot com dot au

By Monday that would be great. Please pass this arround to other brewers who
have used this malt.

Once this experiment is done, others may well be in the pipeline. Contact me
if you have any questions.

Thanks Rob,
Interesting it will be :blink:
Being a big user of Powells malt I have emailed Graham,pleased to be a part of something like this.

Well spotted and thanks again for bringing to the attention of AHB members.

Being someone obsessed with Value I'd be interested to see how this went.
 
Received my email this morning from Graham. He asked me to pass the same email onto any other brewers who might be interested to get their powells malt tested.

Let me know if your interested to help out too or just contact graham at the above email accounts.

Cheers!
 
Email sent also, A FULL analysis would be <_< fun. For the price it is a good malt , works for me.
Down to my last 4kg of base malt :( I need some malt soon ;) .
 
Don't forget this guys
I posted mine off today,Ale,Munich,Vienna and Wheat.
Run out of Pilsner.

Sent mine last week. Only ale malt. Looking forward to finding out the results. Made me think I may give Powells another go. :D
 
Has anyone done their own simple extract test on Powells. The 1lb in 1 Gal ( 453g in 3.79L) mash test to guage extract values for your batch of malt? Is this practical for the homebrewer?
 
I have some pilsner that I will post down tonight.
I had a look at the sack it came in and they do not have batch numbers.
Is mine old or do they not number the batches?


I am also giving it another go untill my Bulk Buy arrives <_<

:super:

for those who posted off some grain for the test <_< did you get the long email from Graham?
Too long to post here [unless your PP :) ] Good read, like the bit in the middle [of a LONG email]:

Did this Bindi.

While it pushed the efficiency of Powells up to 75% it seemed to also create a very dry beer that struggled to hold a head for any length of time (I used a 40 degree rest for 15-20 mins). :ph34r:

I'd have to say that my only reason for the Powells foray was price... After tyring it I'm happy to pay nearly double the price for Marris Otter. It's just more satisfying. :)

Nice, I was wondering about that.

40degrees would be more an acid rest wouldn't it? Maybe the mash pH was too low? Interested to hear the final results of the testing for this malt, as a proper method for using it would save quite a few dollars in the brew process.

30 Degrees is an acid rest... 40 degrees has been deemed a b-glucan rest. :unsure:

I have been doing a rest at 52c for awhile now and have been happy with the efficiency now about 75% also.
Strange that your beer fails to hold a head Warren <_< it's never been a problem here.
Used Powells wheat for a Hefe I mashed today [just finnished] and came close to a stuck sparge, forgot the rice gulls :D . for an OG of 1.062 BIG for a Hefe but I was using up the grains I had left.
