I am looking to brew a Munich Helles tomorrow and after taking a look at Graham W's water calculator over at Jim's I could not get it to balance for the lager profile, although I am not sure how appropriate it is given Helles were traditionally brewed in Munich (I understand matching historical water is not necessarily the best approach though).
After looking at the price of Asda Smart Price water and seeing it being recommended for brewing it seems a no brainer for me to shell out less than £3 to avoid any issues.
Do i need to add anything e.g. calcium chloride flakes to hit a good profile and if so how much (I have this and other water treatment chemicals available)?
Oh and am going to ferment this cold with WLP029 but once the wort is made the water treatment part is over so it won't make a difference which yeast i use right?
