The source presents a washed Geisha from Colombia's Nariño region and discusses a high-elevation growing setting. That combination offers useful context for a lot profile, but altitude alone cannot explain every flavour or establish superiority over coffees grown elsewhere.
Check the specific producer, harvest and processing information supplied by the seller. Geisha is not one uniform product, and a regional name can cover diverse farms and conditions. A washed description also needs to be read as part of the production account, rather than a guarantee of an entirely fermentation-free coffee.
When brewing, use a measured baseline that lets small changes be compared. Taste the cup warm and as it cools, recording sweetness, acidity, body and finish instead of searching only for a predicted floral note. Keep the full label with those observations. A precise account of one coffee is more useful than an elaborate story based solely on elevation and a celebrated variety name.

A good question can make a better brew.
