The Alkon distillery has been in operation for over 100 years, producing a range of infused vodka (honey, thyme, rosemary) and high-quality sadko vodka, along with traditional nastoyka cranberry liqueur. Pick up a couple of bottles here at their small shop (from R120). The website has info in English and there is an English handout in-store.
Don't miss the attached Zavod Bar.
