Sam Gawith and Gawith & Hoggarth are in stock at a number of online retailers about every month or two............Then I found Seattle Pipe Club's Plum Pudding Bourbon Barrel
I'll second the Gawith tobaccos, although their lakeland essence ones are not for me, the twists are something special and quite unique. Seattle Pipe Club is another amazing blending group and I have yet to buy a tobacco from them that I didn't enjoy!
