Any particular recommendations for a £20 Bourbon for old fashioneds/boulevardiers, or should I just get whatever's on offer at Tesco (so Maker's Mark/Woodford I guess)?
Your guess is correct. Wild Turkey Rye would also be an excellent alternative - Old Fashioneds and Boulevardiers are originually for Rye not Bourbon. All still very tasty though.
