Is this under modified malt and will I need to do decoction mash, or at last step mash to get decent efficiency and break down the starches, protein? Has anyone used the malt?

I have used that type of malt in the past and don't think it is undermodified. The soluble nitrogen ratio given in the analysis has a pretty wide spread.

I don't think you need a decoction mash to get good efficiency. With pils malt I wonder how your mash pH was. Maybe that was your culprit.

that sounds more like  a crush, pH, or other water issue.  Best Pils is easily one of the best extracting malts out there - usually 81-82% yield, and the break drops like a brick in the kettle, and clears post fermentation in < 1 week at lager temps.

Its definitely highly modified - in fact, it would be rare to find any undermodified malt available these days.

Kai - looking forward to the interview.

I guess I have to experiment with it little more. My mill is set to 0.040". The same gap I use for the 2-row malt. I’ll set my mill to smaller gap next time. But I don’t think that has much to do with it. I’ll have to get a PH meter to check the PH. The cheap paper strips are useless. PH is usually on the low side, from what I can tell.  I was just surprised by the big difference in the wort appearance between Canadian Malting 2 row I normally use and the Best Malz Pils. The 2 row converts  quick and is clear, and the pils converted as well, but was cloudy, low efficiency and just loaded with hot break, which formed big chunks when I stopped the boil.  My lager is fermenting now, so I’ll report on the results later.

Another thing you want to keep track of is the first wort gravity and the mash thickness at that time. You can use that to calculate your conversion efficiency.
