Thanks to Otto for the TTN. For the last 2 years I have been ordering the "sample" packets from Upton Teas - enough for 4-6 cups and a great way to taste many different teas in short order and not have huge quantities getting stale.
For decades I have ground a different coffee bean each morning [ rotating among whatever the closest good roaster has available ]and have savored the taste comparisons.
Yes, Anders is correct in his observation about tasting chocolate in the same way. At the office today, a sweet toothed friend and I compared a 72% Venezuelan [Valrhona] - tannic bitterness; a 70% single origin Columbian [ Santander ] - beautiful, complex floral notes and 64% single origin Costa Rican [ Choxie ] - quite a bit of caramel sweetness- almost too sweet after the others. I buy chocolates in the disco or fevre form - small, bite size pieces designed for easy measuring by bakers but ideal for tasting forays. It is quite amazing to taste the differences in chocolates. Chocosphere carries a great selection, many organics and single origins. The smell of a waxy commercial chocolate will be nauseating for evermore.
