Macadamia is a noble tree that asks for time, shade and deep soil. At Culpan we grow carefully selected varieties because they find on the slopes of the Santiaguito volcano the conditions they need to yield a nut with creamy texture and clean flavour.

Varieties for a unique volcanic soil

Culpan macadamia grows between 1,271 and 1,432 metres above sea level, in soil formed by centuries of volcanic ash from the Santiaguito. That loose, mineral-rich soil drains well and lets roots develop strongly, a key condition for a crop that lives and produces for decades.

That is why we choose macadamia varieties that respond well to altitude, constant humidity and the shade of the protected forest surrounding the farm. We are not looking for the fastest-growing tree, but for the one that delivers stable nut quality, harvest after harvest, and that naturally adapts to the Culpan microclimate.

Patient selection, generation after generation

Choosing varieties at Culpan is not a catalogue figure: it is the result of the family's patient observation over the years. We watch which trees best withstand the rainy season, which produce consistently and which deliver a nut with a firm shell and a good-sized kernel.

The seeds for new plants are taken from those best trees. In this way, every variety we grow today has stood the test of time in our own soil, and every new tree inherits the best of the one before it. It is the same patience that has defined Culpan for five generations, applied now to macadamia.
