Based on another thread, I was asked to repost an interesting croudsource of information on the coffee we buy:
Make your replies fit the following format;
- Location: at least your country, not the beans.
- Retailer: Were did you buy your beans?online, brick and mortar. Be specific.
- Beans: If a blend, name the brand and type. If single origin, give the detes, i.e. country of origin, region, farm, processing method, elevation
- Roast: Light, medium, dark, french …
- Advertized tasting notes: e.g. stone fruit, sweet, balanced acidity.
- Your tasting notes: Do you agree with the advertized cupping notes? Why?
- Price per unit: e.g. $/lb or £/kg etc…
With any luck we might discover hidden gems, or discover a new favourite or maybe a bargain.


Absolutely not.
The following link is from a different roaster but provides a very good description of this hybrid bean:

What’s New with THA1 Coffee?
With the goal of enhancing quality, improving market pricing, and deepening processing in Vietnam’s coffee industry, THA1 is a new variety that can meet these demands. Origin
THA1 belongs to the Arabica coffee line and is a selected F5 hybrid variety, a cross between TN1 (which has origins from Ethiopian coffee beans) and Catimor coffee. The THA1 coffee variety has a high level of purity and is propagated through seeds. Characteristics
The THA1 coffee variety has the following features:
Well now I want one. Exciting. I feel the tasting notes need a little more detail, especially under different roasts.
I believe it is possible to buy green beans of this variety online.
Doesn’t have to be green. I’m just happy to try something new and see if it bring me caffeinated joy or not. I have varied enough tastes to enjoy wildly different profiles and pre-roasted is fine, but I’ll only buy enough that I can drink it all before it goes stale and loses some of its shine.
It may be difficult to find some THA1 outside of Vietnam since it’s less than 10 years I think since it was developed and it was developed for growing here. Most of it probably gets consumed here, which is true for most of the specialty coffee grown here. The pour over/specialty scene here has grown a lot in the last decade. When I first came here 20 years ago, your choice were the robusta/arabica blends used in traditional Vietnamese phin brewed coffee or the small amount of moka/highland arabica beans used for drink coffee. Now there are coffee events all over the country throughout the year.
Good luck in building an export market. I hope to sample some someday soon.
I’m not in the coffee business so my view is that of an outsider. I am not sure how much the folks here want to develop the export market considering how badly the farmers in the larger export areas are screwed while the middle and end folks repeat the rewards.
