We discuss exactly why this is happening and what the potential solutions are, but also take a deep dive into the history of citrus fruits, from their unique biology, early cultivation, hybridisation and mutation, and discover the great grand parents of the modern citrus fruit industry. We delve into the history of citrus as medicine, perfume and culinary uses, as well as their appearance in art and design. Then we discuss the modern citrus industry, the discovery of new species, and hopes for the future.

Kevin Armstrong is a bartender, bar owner, spirits and cocktail educator and the author of Round Building, a manual for the professional bartender. Kevin rose to fame in the London bar scene over 20 years ago as the group bar manager for the Match Bar Group. He wrote and deployed the most comprehensive cocktail training program of the era, contributing significantly to the critical acclaim of bars like Milk & Honey, The Player, Trailer Happiness, and Sosho to name a few. He has since gone on to open Satan’s Whiskers, which over its 12 years of existence has become one of the best loved bars in London and more recently featured in the World’s Best Bars.

Kev and I were together in Scotland a few weeks ago and got inthralled in some deep conversations about cocktails and bars. He is known to have strong and well thought out opinions on various topics pertaining to drinks and drinking, so I was delighted when he agreed to come on the podcast. I was also keen to hear about the rise of Satans Whiskers as a globally recognised venue.

On the episode you can expect to hear about Kev’s early career in bars and how he transitioned to the match bar group, you can hear us remeniss over the London bar scene as it was in the early noughties, we talk about his time at Soul Shakers working with Michael butt and bars like Mahiki, then becoming a bar operator, first with pubs and then Satan's whiskers. We spend some time talking about modern cocktail bars, both the things we like and don’t like, including homogeneity, ingredients, batching, and more, then we touch on bar awards and finally finish with a surprise quiz! Well, a surprise for Kev that is - not me.
