There is only one hated blend for me: 1792 Flake.
I do not like Latakia, but I could still appreciate plenty about the various English blends I tried. But 1792 Flake was instant and undying hate on my part. But there’s that much more for the people who love it.
That was an unfortunate deal-breaker on BlackHouse and 1882 Founder's, both of which I tried very hard to like.
Also, the latest incarnations of BB1938 and London Mixture had to be gone from my sight, along with F&T Waterloo #2.
McClelland's Syrian Full Balkan, to my grave disappointment, I found unsmokable.
And Rainier Levant, Hood Canal and HH Latakia Flake.
In my fairly short pipe smoking journey, I've only tried two cheaper, OTC blends--Prince Albert and Carter Hall, and I liked them both (actually, I love PA.)
Of all the others I've tried (25+, which covered a range of aromatics, English, and Virginia blends), some I liked more than others, and a few bothered my throat--but I don't know that I've found any of them objectively bad tasting.
Yeh, you know, I tried and rejected Grousemoor early on in my piping, but then in hearing Embers and a few others talking about it, I thought that I would give it a try again. I'm pretty sure that it's not tobacco, but some sort of sadistic herbal torturing device.
Off the top of my head of the more well known brands, Middleton cherry, BR cherry (and their other offerings) , and paladen cherry are all tied for worst. Those 3 specially taste like someone took floor scrapings, poured chery cough syrup on them and splashed in a nice perfume /chemicals and called it a day. I dont know how anyone could enjoy them, but they must have a following?
War Horse Green. Lots of people love it, and I want to love it, but dear god just no. To me it tastes like a half smoked cigarette that sat in a wet ashtray for a week, with a faint hint of stale bubblegum. Bleh.
A lifetime ago when I was but an ignorant undergraduate I sampled Clan.
I thought I had poured perfumed petrol on my tongue and set it alight.
And yet it remains one of the best selling blends in Europe. The Germans in particular are most fond of it.
