Rambling On About Rwanda: The Potato Defect Issue

This is another spontaneous video about Rwanda coffee, as I was just roasting and cupping the splendid new arrivals. Nothing fancy here, but some good information about looking at green Rwanda for possible damage that could result in potato defect taste in the cup. So sad this problem crops up since the coffees we have are pushing 90 points but with potato defect drop to 70 points! -Tom

If I am understanding this correctly, the South and Central American coffees don't suffer the same kinds of infestation after slight damage to the beans. These infections can cause off flavors in the Rwandan beans. They can't be sorted out economically at the commercial level, but we can improve the flavor of the coffee we buy by simply sorting out the bad bits. I might start buying Rwandan again, because I have been avoiding it due to what I thought was a funky flavor.Thanks for the info!

@docsimonson Yes, perfect synopsis.

Always grateful for the pearls of wisdom you share with us Tom. After trying over a dozen different origins finally found a coffee my husband loves..Rwanda Jomba Vunga, it's turned into one of my favorites as well. Being able to see this video will go a long way to making sure we both continue to love this.

This is by far the most intense SO we have tried, absolutely wonderful!

Just pulled a shot of the Ruandan Jomba Vunga, roasted to City+/Full City. Think I must have weeded out any potato defect beans, as the shot was excellent. Blistering not an inappropriate term--very intense, lime/mandarin orange, long, long finish. The beans culled amounted to less than a gram in a 70 gram sample, and of course am not even sure that all of them had potato defect. Just pulled the beans with obvious damage/discoloration, and probably didn't get all such. Excellent, vivid.

I always enjoy your posts! Thank you. I'm watching it while drinking a mug of home roasted coffee.
