I support the idea of boycotting STG (and I was already partially doing so) and supporting those who still believe in quality and variety in the production of pipe tobacco, but...
I live in Switzerland where the choice of tobacco is similar to the USA.
However, the majority of smokers are faithful to flavored blends in bags which are also sold in supermarkets and gas stations or sold in bulk which are found in tobacconists and many smoke pipes with 9mm filters from Savinelli, Vauen, Rattray and similar.
Among the best sellers are Amphora Full Aroma, MB Mixture Scottish Blend and Vanilla Loose Cut, or the various Borkum Riff, Skandinavik etc.
Unfortunately I believe that this type of smokers, who are the majority, do not inform themselves on forums, they do not stock up, they just consume what they find.
Those who can no longer buy Amphora will probably simply switch to Scottish Mixture or Borkum Riff.
However, it is always worth supporting those who still believe in it and buying their products to support them and hope that we will still be able to find good tobaccos for us refined enthusiasts.
