water Ph

[Lone Wolf]

I'm getting back into brewing and I have found out that the water ph down here is about 4.0. How much of a difference will that make in my beer. I extract brew.

The pH of the water is usually of little importance. It is the residual alkalinity of the water that matters. While the importance of that is primarily to a mash, so it wouldn't seem to affect extract brewers, alkaline water can affect the pH of the final beer, which can affect the flavor and clarity of that beer. In general, though, it isn't something an extract brewer needs to worry about much.

If your water has an acid pH, there's probably little chance that your water is alkaline, so the extract will be the dominant factor affecting the beer pH. It probably isn't a concern for you.

if you use lots of dark malts, your ph goes down right? so the lighter the beer, the less you are going to lower ph.
