Your thoughts on using RO water in LoDo brewing?
Looking at LoDo with Gordon Strong recipes that use RO and mostly only using calcium chloride in the mash.
Recipe from Gordon Strongs book "Modern homebrew recipies". I am familiar with LoDo brewing also.What "LoDo" techniques are you concerned about using ...
... that might be "incompatible"
... with the techniques you are using
... from Strong's books?
+1 to include O2 yeast scavenge as well as pre boil. (It’s more convenient IMO).The typical LODO functions re mash water include pre-boiling, underletting, mash caps. The oxygen-reducing effects of those functions have nothing to do with whether or not the water is RO, or if one is adding water salts.
I agree based on Brewing Better Beer pg 150: “…adding enough calcium for a proper mash and then “seasoning to taste” for the final beer.” (from Tully‘s Session Beers pg 50: “It is common practice to add calcium in some form to the mash to help buffer against rising pH, protect certain malt enzymes from heat, and enhance starch conversion (Sanchez 1999, 43).”)There should be no problem in using RO with LODO.
However, building a water with only calcium chloride may not produce the best effect in the beer. The 'no sulfate' in German beers or with Noble hops is a thoroughly disproven myth. Better results will include some sulfate in the brewing water.
Sorry, no.Knowing some of the CaCl is consumed in the mash and doesn’t make it to the kettle, I use a 60% reduction of CaCl to calculate kettle additions. (From Tully‘s Session Beers pg 50: “Since only about 40% of the calcium added to the mash carries over to the kettle, a kettle addition may also be warranted depending on the regional water and beer style being created.”)
Nice!I added 5 grams of bread yeast along with 5 grams of sugar after heating to 100 F.
Results so far:
DO starting point 2.5 ppm
15 minutes 1 ppm
30 minutes 0 ppm
4 hours 0 ppm
24 hours 0 ppm
I found this link very interesting, I also looked at the wort study they did as well.Nice!
There are a couple of articles with a number of variations out there in the interwebs. This (link) duckduckgo search should display at least one of them on the 1st page.
