Love Four Roses! Have to disagree with the standard stuff - it’s nothing special, but you can get it for 20 euros a litre in mainland Europe and as a mixer I find it much nicer than JD. But yeah, the small batch is great and the Single Barrel is even nicer. I have a bottle on the go atm, in fact.
I had the pleasure of meeting their master distiller at a tasting last year, and getting to try their limited-edition releases from 2015, 16 and 17. The 2015 was unreal. All goes for £250+ a bottle though (if you can find it!)
