Pretty good (and there are so many decent earl greys out there to give one a run for one’s money!), though I’m learning as much as I enjoy marveling at the smoothness of a well made cream earl grey I actually prefer mine heavily scented and a bit brisker tasting for some reason—more refreshing, less dessert-rich. This is certainly on the dessert-rich end of the spectrum, with lots of vanilla.
As cream versions go though, this is very well done; with some milk it becomes smooth as butter, with the bergamot element coming in most strongly mid-sip (initially it’s merely fragrant on the nose and then it dissipates after the swallow, taken over by a mouthful of silky cream). Great easy-to-drink texture that doesn’t compromise flavor or overall black tea character. I could definitely see switching up my standard Upton lavender with this sometimes for a regular/near-daily don’t-think-about-it cup, when I want to feel more like I’m eating an afternoon snack than just drinking tea as a pick-me-up.
tl;dr: Not a trace of bitterness or astringency, just butter and silk. Rich rather than refreshing.
