I agree they are blended at home or in a bar. So not included on RB although I have seen them on untapped.
The official pairings were
Screwface & Fizzy Bubbly: I wasn’t keen on this blend the lemon in screwface seemed to overpower the lime in Fizzy Bubbly.
Not So Fast Round Boy & Shake ‘N’ Bake: again wasn’t keen just found too much going on.
Paradise City & Holy Hand Grenade: I actually preferred this blended to separate. The herby lemon complemented juicy citrus and subtle coconut.
Here Gose Nuttin’ & Dodge, Dip, Duck, Dive And Dluce: I liked these the most individually and probably the best blend of the four.
However I did try Shake N Bake with Dodge, Dip, Duck, Dive And Dulce. This blend really worked and for me it was the best blend.
