Casaliva
The northernmost commercially significant Italian oil variety, grown at the thermal limit of olive cultivation. Genetic fingerprinting shows it is the Garda name for the Frantoio genotype — and its oils are measurably lower in phenols than the same genotype grown further south.
In the grove
Casaliva is the dominant variety of the Garda DOP, grown around the lake across Trentino, Brescia and Verona, and recorded under the names Casaliva, Drizzar, Casalì and Nostran since the beginning of the nineteenth century. The tree is vigorous, first upright then weeping — explicitly compared to Frantoio in the catalogues — productive and constant, sensitive to low temperatures and susceptible to peacock spot and olive knot.
SSR genotyping of ancient Garda trees concluded that Casaliva and Razza are synonyms of Frantoio, an old genotype carrying wide intra-varietal variability. That is the honest framing: a locally selected population maintained for two centuries, genetically Frantoio at the marker level, legally and commercially a distinct Garda cultivar. Its phenol figures — 111 to 197 mg/kg in a multi-year Brescia survey — are a clean demonstration that cultivar alone does not set phenol content. The environment does much of the work.

Polyphenol figures are the ranges published for each variety, not measurements of any bottle in the library. A single oil's figure depends on when it was picked and how it was milled, and is shown on that oil's own page where the producer states one.
