The Union Jack hanging outside No.3 St James’s Street today

The King’s Ginger: Too clichéd? We think not – Harry may only be sixth in line to the throne, but this  liqueur is as fiery as the Prince’s fine locks, and good enough for any occasion. Try it with tonic and a slice of orange for an excellent, supremely refreshing apéritif.

We tend not to need an excuse to plump for bubbles, but tomorrow’s nuptials will do. If you haven’t already stocked up on our scrumptious Wine of the Week, then either of these English sparklers are worthy of toasting the happy couple.

2011 Berry Bros. & Rudd English Sparkling Wine by Gusbourne Estate: Yes, we’re biased – but the first English wine to make it into our own-label range is undeniably superb. Loaded with citrus and green-apple fruit, you’ll find one flute-ful is not enough.

Hambledon, Classic Cuvée Rosé: This Hampshire pink is one of our personal favourites – it offers bright red berry fruit with added layers of toast and lemon.

And from across the pond…

2016 Au Bon Climat Wild Boy Chardonnay: In honour of the once-wild prince, this utterly delicious Chardonnay is made by California’s very own “wild boy” Jim Clendenen, exclusively for the UK market. Expect pure fruit, elegance and a slight nuttiness.

2014 Birichino St Georges Zinfandel, Old Vines, Nonagenaires: Influenced by the two saintly Georges that look after these old vines, this Zinfandel will be perfect for the post-“I do” barbecue – bright and juicy with plenty of structure.

NB All of our recommendations are – at the time of writing – available to buy in both our London and Basingstoke shops
