Researching Verjus today ("vair-ZHOO") via @bonappetit https://www.bonappetit.com/test-kitchen/ingredients/article/verjus
This has led to the discovery of Ferdinand's Riesling Grape Cordial.
We know Ferdinand's well from their Saar Dry Gin offering but here they create a non-alcoholic syrup, flavouring primarily with unripened Riesling grape juice, as well as alpine herbs and similar botanicals that we know and enjoy from their signature spirit (lemon, thyme, sloe berry).
We look forward to trialling and testing at our HQ in the coming weeks and no doubt will be included in an upcoming cocktail recipe.
Any thoughts, bottle recommendations, uses are always appreciated in the comments section.
