Pumpkin spice: Why are we so obsessed with the flavour and scent?

In short, yes. But this is a hotly-debated topic.

Coffee enthusiasts argue that adding actual pumpkin is unnecessary.

Timothy Sharp, manager of Sparrow Coffee House in Cardiff, makes his own homemade syrup, adding spices like cloves, cardamom and star anise to the core PSL ingredients of ginger, cinnamon and nutmeg.

But pumpkin is not included.

“I see it as the spices that go into a pumpkin pie,” he said.

“I’m not sure I would want to taste pumpkin in my latte”.

However, Ms Enness insists actual pumpkin should be there.

Her staff order tins of pumpkin puree from the US, and add it into their syrup, which Chelsea said gives the coffee a distinct texture.

“I don’t think it changes the flavour that much,” she added.

“It’s just knowing that it’s in there.”
