It doesn't stop me (much) from enjoying this or that product, but unless I have solid evidence (i.e. the 3 microdistilleries within walking distance of my home), I assume all liquor brands are owned by a behemoth multi-national like Diageo and even if it says "since 1643" on the label that recipes/blends/ingredients are constantly tweaked to lower cost and cater to focus-grouped tested tastes.
