Ph difference of 0.3 tasteable ?

[adam01]

I'm trying to clone Warsteiner Dunkel. I'm pretty close, but the commercial has a bit more sweetness, and is smoother.

I checked the pH of the two. Commercial is around 4 (3.97). Homebrew is 4.32.

Would this difference account for smoothness or sweetness perception ?

I wouldn't know if such a narrow range could be detected by the palate. I do know that the typical lager is about 4.4 pH and the typical ale is about 4.1 pH (both, give or take a couple tenths). Did you allow the commercial brew (or your home brew for that matter) to go flat and also rise to room temperature before measuring its pH?

Your 4.32 pH is certainly within the normal range.

Add some acid to your beer to match the commercial one and see what happens.
