Grousemoor does have a more citrus scent to it than a floral type scent (imho) which doesn’t translate into the smoke. I wouldn’t say it was lemongrass per se, but something akin to it, maybe something more like a Key Lime Pie or something; not so in your face as a freshly cut citrus can be. It’s a nice, light, spring time type smoke but isn’t floral like Grasmere which, to me, tastes like rose water and Turkish Delight. I don’t recall ever knowingly had rose geranium oil for any purpose so I couldn’t say if Grasmere has Rose Geranium oil in it or not.
I’ve got some Bosun’s Plug on the way which, according to the internet, has rose geranium in it; I’ll let you know if that’s true when it gets here. ?
