Thanks - great article. The consensus there seems to be that adding a pH to my kit is well advised. Who uses a pH? I am just gonna get a cheapie from TakeALot.
Baseline: Add 1 tsp of calcium chloride dihydrate (what your LHBS sells) to each 5 gallons of water treated. Add 2% sauermalz to the grist.
Deviate from the baseline as follows:
For soft water beers (i.e Pils, Helles). Use half the baseline amount of calcium chloride and increase the sauermalz to 3%
For beers that use roast malt (Stout, porter): Skip the sauermalz.
For British beers: Add 1 tsp gypsum as well as 1 tsp calcium chloride
For very minerally beers (Export, Burton ale): Double the calcium chloride and the gypsum.
These recommendations should get you a good beer if not the best beer. To get the best you should vary the amounts of the added salts noting carefully whether a change benefits or detriments your enjoyment of the beer. Additional sulfate will sharpen the perceived hops bitterness. Additional chloride will round, smooth and sweeten the beer. Add or decrease these in small amounts.
Not always true, you only really know your water profile if you had it tested. Our RO system here at home takes the 90-odd ppm TDS that is Pta tap water (which is close to the TDS value of GreGorGy's RO water) and filters it down to 12 TDS, the installer measured it when we had it services 2 months ago. So, even though both sources are RO water, their mineral content still isn't the same.Personally I would skip the cheap PH meter, if you are starting from RO water you are starting from a blank known slate. You can add your gypsom and calcium as they reccomend and see if you like the diffrence they make.

Even knowing the TDS value still doesn't give you a breakdown of what those solids consist of, and their respective values.
It's really all just guessing until you have an actual water result in your hands. The thread I linked to is supposedly an educated guess as a starting point. I will admit I haven't used that method myself, as Brewfather allows me to make more specific additions if the source water profile is known- if and when I get the chance, I still buy from a shop that has the profile listed- at least partially. Knowing only the TDS value of my own 'RO' water isn't as confidence inspiring as having more detailed info available.
Well, I think buying water from a shop might be the easier way (for brewing water only), and at least initially cheaper. Getting a home RO system is a lot of up front costs, not including paying for the water analysis. Then there's also the services to keep in mind. I'm not even sure there is a break even point regarding costs vs buying from a shop- there may be, but I haven't bothered to try and do the math. Where the difference comes in, at least for us, is having access to RO water all the time, for cooking, coffee, drinking, brewing... The convenience factor is what I believe will swing it (or not).Ahh fair enough, I dont have a home system. I buy from a shop that has a fairly complete report.
Thanks for the detailed reply I was debating whether to get a home system but its sounding more and more like the shop is the way to go.
How do you guys wash your bottles? I have just stuck a whole lot into the dish washer but I'm not sure if thats going to work.
I rinse out a bottle immediately after use, and wash them after the beer is consumed (sae day / next day), instead of waiting for a batch and making a lot of work for myself. Then come bottling day, I'll rinse and sanitize them. Though I keg now, I still bottle maybe 6 or so from the leftovers in the fermenter.
I no longer use the dishwasher, the soap messes with head retention I rinse it properly after drinking then clean with oxy cleaner and sanitize on day of bottling.How do you guys wash your bottles? I have just stuck a whole lot into the dish washer but I'm not sure if thats going to work.
