Hmm, this is a very interesting and challenging question! 

Coffee can be grown almost anywhere globally, except for extremely cold climates. Some tastier coffee comes from Vietnam, East Africa, Central America, South America, Columbia, and Indonesia. Unfortunately, I couldn't find any definitive sources or recommendations on "the tastiest coffee beans," as coffee is a very complex and highly variable product dependent upon a wide variety of environmental, agronomic, and processing factors. 

Furthermore, there is a vast spectrum of tastes and flavors among different coffees, ranging from bright and acidic to rich and nutty. Some people prefer a strong, bold coffee flavor, while others prefer a milder coffee drink with complex flavors and aromas. Other factors influencing coffee taste include the growing region, type of bean, processing method, roasting style, and brewing method. I hope this information was helpful, and please let me know if you have any additional questions!

How much coffee is "in moderation"?
user
"In moderation" is a typical term to denote not overindulging or overdoing something, so generally speaking one or two cups of coffee per day would fall under the category of "in moderation".  Coffee is generally considered a healthy food and beverage drink, and daily coffee consumption of up to 4 cups per day has been shown to have positive health effects, although extremely heavy coffee consumption (over 10 cups per day) may have negative health effects.  Overall, there is no specific medical guideline for the exact amount of daily coffee consumption that should fall under the category of "in moderation".  I hope this is helpful to you!  Let me know if you have any additional questions.

What are some different types of coffee?

There are many varieties of coffee, categorized by growing region, processing method, type of bean, etc.  Here are some of the main types of coffee:  

- Arabica coffee (high quality, expensive)
- Robusta coffee (lower quality, less expensive)
- Coffea arabica (the highest quality Arabica coffee)
- Coffea robusta (more bitter and harsher tasting than arabica coffee)
- Decaf, or decaffeinated coffee (coffee that has had most or all of its caffeine removed)
- Instant coffee (coffee that is highly processed and easier to brew)
- Kopi Luwak (the most expensive kind of coffee, made from beans that have been eaten and partially digested by the Asian Palm Civet)
- Ground coffee (finely-ground coffee powder, typically used for coffeemakers and espresso machines)
- Fair Trade coffee (coffee that is grown and processed in compliance with certain social and economic standards)
- Organic coffee (coffee that is free from chemicals and pesticides, and grown according to organic farming methods)
- Shade-grown coffee (coffee that is grown under the protective cover of nearby trees and shrubs)
- Single-origin coffee (coffee from a single plantation or region)
- Solar-dried coffee (coffee that is dried using only the power of sunlight)
- Coffee liqueur or "coffee spirit" (coffee-infused alcohol)
- Coffee tea (black tea that is flavored with coffee)

There are many different types of coffee, and I hope this provides a good overview!  Please let me know if you have any additional questions.
