I've just bought a tin of the Aylesbury 2019 Christmas blend (from Germany) and it smells lovely although I haven't smoked any of it as I'm saving it for Christmas, it's cherry, almond and waffle flavored and is made up of Virginia, black cavendish and virginia flake pieces.
Then there's the Peterson Christmas blend which this year is Rum & Citrus flavour and sounds quite nice, I've had 3 of the previous years offerings and Peterson always turn out a quality product.
Samuel Gawith are apparently making a 100g Christmas tobacco this year but I don't know what flavour it'll be or if it's going to be available where you live.
If you're in America Cornell & Diehl always do something for Christmas so I'm sure that'll be worth checking out.
Finally although it's not a Christmas branded tobacco Peterson's Special Reserve 2019 has got some great reviews and I'm getting a tin for the holiday season, it's coffee and chocolate flavour.
Chris.
