Olive oil labels are full of terms that sound reassuring but don't always mean what shoppers assume they mean. Some are strictly regulated. Others are marketing language dressed up to look like a quality claim. Here's a plain-English guide to what actually matters, and what's mostly noise.
"Extra virgin"
This is a legal grading, not a marketing phrase. To qualify, oil must be extracted mechanically — no heat, no chemical solvents — and meet defined chemical benchmarks (primarily free acidity and peroxide value) alongside sensory panel assessment confirming there are no processing defects. It's the highest quality grade of olive oil available. What it doesn't tell you is how fresh the oil is, where it came from, or how it's been stored since pressing — none of which are part of the grading criteria.
"Cold-pressed" / "cold extraction"
This means the olives were processed without added heat during extraction, which helps preserve flavour compounds and polyphenol content that would otherwise degrade. Genuine extra virgin olive oil is, almost by definition, cold-extracted — heat-assisted extraction pushes an oil out of the extra virgin category entirely. So while the term is accurate, it's not really a distinguishing feature between two oils that are both genuinely labelled extra virgin; it's closer to a baseline requirement than a bonus feature.
"First press" / "first cold press"
A slightly outdated term carried over from old hydraulic press technology, where oil extracted during the first pressing of the fruit was considered superior to any subsequent pressings of the same leftover paste. Most modern producers, Olio Nuovo included, use single-pass centrifugal extraction rather than the old multi-press method — so there's no "second press" to compare against in the first place. "First press" today is largely a legacy phrase rather than a meaningful quality signal.
Harvest date vs. best-before date
We've covered this in more depth elsewhere on our blog, but it's worth repeating here because it's one of the most commonly misread parts of any olive oil label: the harvest date tells you when the olives were actually picked and pressed. The best-before date is calculated from the bottling date, which can happen long after pressing — sometimes over a year later, following extended bulk storage. If a label shows only a best-before date with no harvest date at all, that absence is itself worth noting.
Country of origin
Under Australian labelling requirements, blended oils must disclose their countries of origin. However, a blend sourced from multiple countries and multiple harvests can still legitimately carry the "extra virgin" designation, provided it meets the grading criteria. A single-estate oil, by contrast, comes from one specific place and one specific season, which makes its origin story dramatically easier to verify — there's no blend to account for.
Acidity level
Some labels display a free acidity percentage (extra virgin olive oil must sit below 0.8%). A lower number generally indicates higher quality fruit and gentler handling, though acidity alone doesn't capture flavour, freshness, or polyphenol content — it's one data point among several, not a complete picture on its own.
What we put on our label, and why
Olio Nuovo is labelled with its Bylands Estate origin, specific harvest details, and independent award recognition — because those are the facts that actually tell you something concrete about what's in the bottle, rather than terminology that sounds meaningful without adding much.
