Lacking a little flavour but surprisingly easy to drink, it's very fresh and would be great on a hot day when you want something light. I prefer it with a little less Campari, despite it being one of my favourite liqueurs, making it 4:4:3.
Unfortunately I found this a bit bland. Also, a little too much on the tequila side; though, on the flip side, it would work well with a nice strong flavoured tequila.
Too boozy for me, I would tone down the vodka to 45/30ml.
Better than a Moscow Mule, the Cognac works with the ginger. I usually add less sugar syrup for cocktails, but this amount worked well, but that depends on how sweet you ginger beer is.
A bit too rich for me, but I added tonic and it lightened it up perfectly. So I would recommend a Negroni and Tonic.
Did this recipe change in the last couple of months? I seem to remember it having more tonic water, which I think it needs, I ended up putting 75ml instead and it's much more refreshing.
