My take on glass distillation is that it yields a nonchalant oil, untouched by the effect of the still materials (copper, steel, etc). The oil is clean, crisp and loud, much like a steam distilled oil. You get the character of the tree, untainted by the artisan's technique. As such, it is a mechanical process more so than an art form. The character of the oil is lacking the hallmark signature of the craftsman. Here we have departed the abode of art or traditional craftsmanship to enter the realm of advanced technology.
A suitable simile would be Turkish coffee. Traditionally, it is only brewed in a copper pot. A connoisseur will reject a cup of Turkish coffee boiled in aluminum as a distasteful innovation. Can you imagine a cup of Turkish coffee brewed in a glass pot? It would taste like a common French press, very clean and clear, but without that characteristic signature taste that makes Turkish coffee enthusiasts stick to their traditional brew.
We have Indian ouds with the same characteristics, however these were induced by the water type used during distillation rather than the material of the pot.
I have no projected upcoming glass distillation, being a fan of copper distillation myself, but if we find a large enough pot and the right batch of raw materials, I'm open to doing another run.
