Martin - what is your suggestion for the ppm levels of calcium, magnesium, sulfate, chloride, etc...?



Although it goes against everything we brewers hold dear, I keep seeing evidence that a 40 or 50 ppm minimum calcium content may not be the best for flavor in those light European lagers. The boiled Munich profile might only have around 12 to 20 ppm Ca and the rest of the ions are low too...excepting for bicarbonate.  That profile suggests that all the flavor ions are less than 20 ppm. That evidence makes sense since those Munich beers are malt focused and there is little need for the water to impinge on that.  The same attribute applies to Pilsen water...very little flavor ion content to color the malt focus. 

The one thing that is also apparent from the boiled Munich profile is that it still has a lot of bicarbonate and the brewers would have to dose with acid malt to neutralize that component. For some beer styles, it will be a significant dose.  But I don't expect that most people would taste it. But there might be nuances from the lactic acid that do color the beer flavor.  That is why it's imperative that brewers use lactic acid or acid malt when brewing German style beers.

Thanks Martin!

i woulda thought you'd do 144 for 20 min and 158 for 40, being that its a malt forward style, no?

Ron,

The chalk is not needed or desired for that mash. Both the calcium and bicarbonate are far too high.

Ron. Was the Ca enough to offset that HCO3? Was the pH on target?

OK...I only added half of the salts to the mash so far.

That should leave me with this:

Ca - 60ppm
Mg - 2.5ppm
Na - 14.3ppm
SO4 - 9.6ppm
Cl - 5.3ppm
HCO3 - 127.2ppm

I'm hoping the Carafa will keep me in acceptable limits. My experience has shown this to be the case.

I based this water profile from Kai's research on his website.

Ah, sorry to see that on Kai's site. While it's accurate for the tap water, its not what is brewed with.

Do review my presentation on Historic Water from this year's AHA convention.  In the old days, the water was pre-boiled to knock out some of the excessive alkalinity and the calcium goes out with it.  After boiling, Munich water is a semi OK water to brew with as long as you then attend to the remaining alkalinity.

I'll follow up on this presentation. Thanks.

I only went with half of the prescribed salts to finish with this:

HCO3 - 127.2ppm

This thread has been fun and educational. I have set up for brewing tomorrow, grain is milled, and I used Martin's Munich Boiled water specs. Will see if I hit the target pH. Doing a hochkurz double decoction, should be a great day to brew a lager.

Indeed. I wonder if it will become as long as the "That German Lager Flavor" thread.  ;D

Either way, I need to brew a Munich Dunkel here soon. Might be my first 10 gallon batch.

At the 158F Alpha rest. Going pretty good so far.  ;)

The malty aroma from the boil is still lingering in my garage. :)

Doing a diacetyl rest on mine. Ready for extended lagering in a day or so.
