Tullibardine 500 Sherry Finish
The 500 Sherry Finish is matured for an undisclosed period of time in first-fill bourbon casks before being filled into 500-liter (hence the name) Spanish Pedro Ximenez sherry butts for one year. The final whisky is bottled at 43% ABV, and is both chill filtered and (probably) has added spirit caramel for coloring. (Sigh.)
