Is Buttermilk (Low-fat) Acidic or Alkaline?
Buttermilk (low-fat) (raw) is neutral: PRAL close to zero: hardly shifts your acid-base balance.
Classification
Low-fat buttermilk doesn't differ from regular buttermilk in PRAL. Both sit at −0.1 per 100 ml. Fat content plays no role in the mineral balance. What counts is protein and phosphorus on one side and calcium and potassium on the other, and they balance each other out. There's no difference in calories either, at 39 kcal per 100 ml.
In the Dairy category, buttermilk (low-fat) (raw) ranks #6 of 25, sorted from alkaline to acid-forming. More alkaline options include Whipping cream (−0.2), Skimmed milk powder (−0.9), Whey (liquid) (−1.9). More acid-forming are Crème fraîche (0.0), Schmand (sour cream, 20% fat) (0.0), Goat milk (+0.1).
Acidic or alkaline: PRAL, not pH
On this site, acidic and alkaline refer to the PRAL (potential renal acid load). It estimates what a food leaves behind once it has been digested: a positive value is acid-forming, a negative value is alkalizing. That is different from the pH of the food itself: a lemon tastes sour, yet its PRAL is −4.0, so it is alkalizing. Your diet does not change your blood pH. It does change how much acid your kidneys have to deal with.

Frequently Asked Questions
Is buttermilk (low-fat) acidic?
It depends on what you mean by acidic. The pH describes the food itself, for example how sour it tastes. The PRAL describes what it leaves behind after digestion: Buttermilk (low-fat) (raw) has a PRAL of −0.1 per 100 ml, so it counts as neutral in your daily acid-base balance.
Does buttermilk (low-fat) count in the acid-base balance at all?
Hardly. At −0.1 per 100 ml, buttermilk (low-fat) is in the neutral range between −0.5 and +0.5. You can eat it without shifting your balance.
