Merlet's Lune d'Abricot in perfect bitterweet balance with the Averna. Apricot darkened by the amaro, lifted by the citrus. (Choose your apricot brandy wisely. De Kuyper's apricot brandy, for example, would make a very different, much sweeter cocktail)

Sweet woodruff (gallium odoratum) is the main ingredient of Maiwein https://en.wikipedia.org/wiki/May_wine

Looks like an update/ variant of the Sparkling Perry (yours, from 2002)?

Difford's Guide recipes using cranberry juice are made up and balanced for Eager Cranberry juice, which has 14.1g sugar/100ml.
Ocean Spray cranberry juice has just 5g sugar/100ml, so needs an extra 9g sugar/100ml to bring it to the level of sweetness that the recipe expects.
Fortunately, 10ml of Monin rich sugar syrup contains 9g (actually 8.55g) of sugar, so for every 100ml of Ocean Spray cranberry juice we use in a recipe, add 10ml (1o%) of rich sugar syrup to get the target sweetness.
