I use the same amounts of
tobacco for my macerations (full cigar and one ounce of loose
tobacco, which are generally the quantities I buy), although my target yield has been a bit higher than yours---about 100ml, down from 130ml last year. I started out in Spring 2013 using half that much tobacco, but I see no point to that anymore, since I have no intention of extracting the same tobacco a second time, and I don't want to have an ever-increasing inventory of baggies with half a cigar or half an ounce of loose tobacco.
Recently I've had thoughts of going to lower yields of extract, such as 60ml. Those intentions haven't yet materialized, though, because I like to be able to see the solvent liquid in the maceration jar (as a way to easily verify the color change). Starting with 70-80ml (which will yield 60ml) is barely enough solvent to cover a cigar or an ounce of tobacco, so I've typically added more. That's going to change, however.
My next batch is planned as low-heat-assisted macerations using a solvent of 85%PG/15%PGA, and I intend to force myself to add only 70-80ml of solvent at the beginning. Ending up with 3-4 ounces of finished extract is overkill and pointless for me, since I'll never be able to vape or give away that much. Four-ounce glass dropper bottles are expensive and take up too much space anyway. I've already got a huge drawer filled with my own extracts, plus two smaller drawers filled with swapped extracts from you,
Johni,
Dustmight,
MFToms, and
clnire. I'm completely out of storage space!
If I didn't enjoy making extracts so much, I'd stop now, because I have enough already to make juice for an army. At an average mix ratio of 20%, my current stock of NET extract would make 20 liters of juice. Shoot, that's just plain silly.
