pH 3.2 – 3.6
Exceptionally acidic
Highest gluconic-acid concentration. Strongest antimicrobial action. A lower-range reading is a reliable indicator of a high-quality raw honey.
pH 3.6 – 4.2
Moderately acidic
The most common range for floral honeys. Good preservation capability with a balanced, pleasant acidity on the palate.
pH 4.2 – 4.5
Mildly acidic
Less sharp; bitter or tannin notes often dominate. Still well below pH 4.6 — the spoilage threshold where harmful microbes can establish.
