I found it a touch sweet which also masked the Campari a tad. Dropping the syrup to 12.5ml gave the Campari more space without it dominating....which I know it easily can before your palate acclimatises
Impossibly sweet. Tried getting some kind of balance back using 60ml bourbon but still way too sweet. An extra 20ml of Sazerac rye brought some kind of relief but by then it had become very very boozy. There was very little subtlety by this point though
Also works very well with Lillet rouge...maybe slightly drier but only marginally. Also tried it with orange bitters, aiming to pick up the distinct orange flavours from the non-wine ingredients. A nice enough drink resulted but with a rather less subtle, sweeter orange hit up front. What a brilliant original recipe!
