Default Water Analysis

My next batch will be my first AG batch and I was looking to save a little cash by using my tap water. Unfortunately, I have hard water. I'll be brewing an IPA so should I try and treat this water or just buy some water in the 5 gallon jugs? If I buy the bottled water would I need to mess with the PH?

I just fooled around with Kaisers spreadsheet and I would say brew it. The only concern I would have would be how do you plan to sparge, because you could get a PH above 6 but you could also acidify your sparge water.

I'm going to batch sparge.

I would try to play with the calculators and maybe add some lactic acid (about 2-3 ml tops) to the sparge water. It's also going to depend on you water volumes of strike and sparge.

Let's say you want 7g preboil volume and have about a 12.5lb grain bill (estimated of coarse)
Water use
total water 9 gal
Strike water 5.5 gal
Sparge water 3.5 gal
That would give you a mash ph of 5.6 and you would need 2.3ml of lactic acid in sparge water

Thanks for the calculator tip. I was messing around with it. I still have a lot to learn about the science behind brew water

My grain bill will be 13.5

BeerSmith is calling for 8.81 gallons of water
Strike water of 5.52 and Sparge water of 4.34


I'll look into the acid additional. I appreciate the insight.

For IPAs,

High Alkalinity = Bad ------- High Hardness = Good

Calcium & Sulfate could be boosted a bit via Gypsum.

Bicarbonate is quite high.

Sodium is a little high, but not ridiculous.

Take a look at http://www.howtobrew.com/section3/chapter15.html - pH of the water isn't really a big deal. It's the pH of the mash that matters.

Don't forget to deal with the chlorine if there is any.

I don't think I would make any additions until after I brewed it and evaluated it. jmo

I use my tap water (hard water) and both of the AG brews I've done have been great.

Would it be OMFG amazing if I used soft water?

Gypsum alone would not hurt an AIPA with this water profile. It would however make it better.

93 Cal is moderate and 117 Sul is certainly at the low end of the range for this style.
