Question 2: Which type of oak is most commonly used for American Standard Barrels (ASBs) used in Scotch maturation?
- Quercus robur
- Quercus petraea

Correct answer: Quercus alba
Quercus alba (American white oak) is the species used to make the ASBs that previously held bourbon and are widely used in Scotch maturation.
Question 3: A 'first-fill' ex-bourbon cask differs from a 'second-fill' primarily in that it:
- Has never held any liquid before
- Imparts more intense flavor and color (Correct answer)
- Is made from European oak
- Has been charred more heavily
Correct answer: Imparts more intense flavor and color
A first-fill cask still retains substantial flavor compounds from its bourbon content, imparting stronger vanilla, coconut, and oak character than a second-fill cask.
Question 4: Which wood treatment process, applied to the inside of bourbon casks, creates a layer of charred carbon that filters the spirit?
