- Your sensitivity to caffeine
- Your willingness to explore rare or specialty beans
How to Know What You’re Buying
Here are some tips when buying beans:
- Read the label: Reputable roasters usually state the bean type and origin.
- Try single-origin coffee: This helps you learn what characteristics you like.
- Ask for samples: Many specialty coffee shops offer tastings.
- Buy in small batches: Coffee loses freshness quickly once opened.
Mixing Bean Types: Blends
Some coffee roasters mix different types of beans to balance flavor, aroma, and body. For example:
- A blend of Arabica and Robusta offers both smoothness and strength.
- Liberica or Excelsa can be added to introduce complexity.
Try blends to enjoy a more rounded profile or experiment with single-origin beans to explore specific flavors.
