So is the thinking the alkanet was disolved in the spirits, then the alkanet/spirit mixture added to the other ingredients?
My father was a still maker in S.E. Georgia in the 40's and 50's. I recall watching him weld up a mash cooker when I was around 5 or so years old. As he owned a truck repair shop, no one much paid any attention when he was welding up something. And I hear you about the lead. Dad used silver solder for everything that touched the liquids, especially in the condenser. His family had a long tradition of making spirits.
Maybe I should make a small still and render down some Cabernet into Spirits of Wine.
