Wow, thanks for the explanation! My journey started with attempting to replicate Backwoods Brew's Malty Toffee, since it has been my daily vape for years and they went out of business recently, but I'd be happy if I made an acceptable substitute. FTR, I drip almost exclusively, and build my own coils at 1.0-1.2 ohms. When I'm out and about, I'm a simple gal with a Kanger Protank 2 and something fruity.
BWB's Malty and Malty Toffee were the ONLY two ejuices that were 30PG/70VG in their entire inventory. You even had to check the box affirming you were aware they were 70% VG before checking out your cart.
I figure there has to be a reason they are that high in VG - which is OK with me. Any PG higher than ~30-40% causes me to break out in hives. I learned that the hard way! When I first started vaping 4 years ago, it was at 80PG/20VG, because that was the default mix at the online vendor where I bought my juice. After a lot of research, trial and error, and Benadryl
I realized I have a minor PG intolerance. I had no idea at the beginning I could change the PG/VG ratio when ordering. I keep PG at 50% or more to be on the safe side. I also can't do max VG, because it causes my lungs to become heavy and I wheeze.
Gee whiz, this is much more complicated than opening a pack of Marlboro's and lighting up. But so much more worth it!!! But I digress.
Getting back to my original topic.... Don (the BWB mixmaster) has hinted very strongly about the ingredients. Malty is almost certainly made of only a high % of Ethyl Maltol (EM), nic, and PG/VG. Hence the name Malty. He's practically said Malty Toffee is only two flavors, which I interpret as the base being the original Malty ejuice, and adding Toffee. The key is percentages and flavor vendor.
I've only been mixing 10 ml batches as experiments. The first one, with 5 flavors + EM (VG Toffee, English Toffee, Vanilla, Holy Vanilla, and Buttercream) that I found on a search wasn't even close. The second 10 ml batch of 15% VG Toffee and 10% EM was almost unvapable. I poured most of it down the sink. Bleh!!!
This last batch was 15 ml consisting of 10% PG English Toffee and 10% EM - the closest so far! But still not quite right. After vaping a few so-so ml, I added 1 gram of Sweetness Sweetener (DIYFS), and BAM! There it is!!!
It's not quite Malty Toffee, but damn! It's better!!! Malty Toffee was satisfying, in the way Marlboros were. But I always wanted more. To me, the flavor was....elusive?
But this batch puts it out of the ballpark, and would give
@Dkrom68 a run for his money.
