As far as I know,at least two years of maturation is a requirement for a whiskey to be called "straight bourbon". But, in many articles I read on the web and also in many translations in Turkey, it's stated as a requirement to be called "bourbon". So;
1. Am I right about the definition above?
2. Is there a min. maturation period requirement (less than 2 years, ok) also for "bourbon (not staright bourbon)"?
3. Are there any bourbons which aren't straight bourbon?
