Yeah, I used it in a kit based beer last year at FO and Dry and I absolutely loved it. I've been meaning to do an AG version for a while but never got around to it until now. Similar to Bookbinder hopping only better :-)

All finished up now, even mopped the kitchen floor to create some good will :-)
Brewhouse efficiency was up by about 5% from 75% to 80% simply by changing from Maris Otter to Global Cologne. Still hit my OG of 1.042 but ended up with 23L in the fermenter instead of the expected 21.5L. Any one else had improved efficiency with this malt?
The only "known" process change that I made was that I mashed out for the first time ever today. I guess that could make a difference too???
My experience with Maris Otter was that I dropped about 8 to 10% on my mash efficiency with the first couple of batches I used it for.
Then I figured that by mashing for at least 90 minutes instead of the usual 60 minutes, I could recover most of my losses.
I don't believe a mashout affects your efficiency, just possibly the fermentabilty profile of your beer.
I'm sure different malts give me different efficiencies. For example, Golden Promise has always worked well for me, better than Maris Otter.

I've heard someone else say this as well. But I'd be interested to know if people are calculating this from the actual potential extract of the grain or using a standard 'two-row' extract number in their software.

This is where I'd put my money. By heating the mash up you've just decrease the it's viscosity and freed up a little more starch that will still convert if the mash isn't raised above about 78C
I had an increase in efficiency when I started using this stuff. I don;t know what it was about it - but you get the same efficiency with the Global Pilsner malt too.
I think because the berry size is so fat you are getting more fermentables weight for weight than what you do with a lot of the other stuff.
Make the most of it though - there's no more Colonge malt in the country until March... and I only have 1/2 a sack left!
