Kona coffee has been cultivated on the western slope of Mauna Loa for 200 years. The Kona belt — a narrow strip of volcanic soil, afternoon cloud cover, and elevation — produces a flavor profile that's distinct because the growing conditions are unrepeatable anywhere else. Fumiko's grandfather arrived from Japan in 1922 and planted the trees her family still cultivates. She knows every tree by variety, age, and yield history. She'll show you what she's selecting for — the brix reading in a ripe cherry, the way the skin gives under pressure — and then she'll let you pick for an hour, hull them by hand, and put them through the mill. Then comes the cupping: five coffees, side by side, and you'll finally understand why the growers charge what they charge.

What Your Day Looks Like
Morning (9am)
Meet Fumiko at the farm gate. She begins in the nursery — the seedlings she's propagating from her best-performing trees. She explains Kona Typica, the heirloom variety her grandfather planted, and why it produces a lower yield but a higher cup score than modern varietals. The drive up to the mid-slope section at 2,200 feet — the optimal elevation in the Kona belt.
Mid-morning (10–11:30am)
Picking session. Fumiko teaches cherry selection: the brix reading, the color graduation from green to yellow to red to dark red, the way the skin gives under pressure when ripe. You pick for an hour in one of her best rows. Then pulping — she shows you the hand pulper, then the mill, then the washing channel. The smell of fresh-hulled coffee is unlike the roasted version entirely.
Cupping (11:30am–1pm)
A proper cupping on the farm porch. Five coffees: her standard estate blend, two single-lot selections from different elevations on the farm, a natural-process lot she's experimenting with, and a neighbor's estate for comparison. She explains cupping protocol — the spoon, the slurp, the retronasal evaluation — and then you taste the differences. It changes how you understand coffee.
