The extra 10ml of whisky in the ratios really helps as its not as bold as the gin inthe original but works well

Tried with bourbon, very enjoyable...

As the man himself has pointed out there aren't too many Welsh themed cocktails. So swap the whisky for Penderyn and switch to yellow chartreuse and you'll have yourself a 'St David's harpist ' just in time for St David's day - phew! Both versions pretty tasty

The Last Word is one of my favorite cocktails, but I find this to be superior. I stick to the specs and feel it benefits from a good long shake. I have tried it with more expensive Irish whiskeys but find regular Jameson works quite well. Excellent work Mr. Difford.

I think you're going to have to use a pretty flavorful whisky if you want to notice it. Probably prefer a Last Word over this but it's definitely not bad.

I like it better than The Last Word, but agree with many of the comments below - the whisky is hard to notice.

We love this, so bravo! And we think it does well with Mezcal in place of the Whiskey. In which case it may be an "il trovadore de Zacatecas".

It's pretty good as is, but for me it's a bit too overpowered with Chartreuse and Maraschino.
I like this better:
1.5 oz Irish whiskey
0.5 oz Green Chartreuse
0.5 oz Maraschino Liquor
0.5 oz Lime juice.
