I recently started making my own juices.. I have no plans to just stop buying pre-made juices from good vendors anytime soon. It is doubtful that I'll be able to duplicate Indigo's tobacco flavors, or many of the other things I enjoy. But vanilla custard, I will never buy again. I still wouldn't mind trying Grant's sometime just for comparison, but it just seems like it's something you can't go wrong with.
I've made a few batches using Capella's Vanilla Custard at 15-17%, throw in another complementary flavor at 1-4% and a tiny bit of ethyl maltol. - They taste great a few days in after some hot water baths and I'm assuming they will only get better.
Being new to this maybe this is a known thing.. but in case anyone else just starting out likes custards and hadn't tried this I just wanted to share. It's a great place to start for a first recipe.
i use capellas vanilla custard at 18% with some capellas french vanilla and a couple of drops of ethyl maltol.
after steeping i compared to grants and it was the same
Would you mind sharing the exact ratio/percentages that worked for you? How much French Vanilla and "a couple of drops of ethyl maltol" into how much liquid?
Perpetua’s Vanilla Custard (PVC) To make (aprox) 10ml:- Add 2.0ml of Capella Vanilla Custard, 0.5ml of French Vanilla, 2 drops of sweetener, to 7.5ml of your preferred VG/PG/Nic mix.
<<<i got that from alchemists cupboard http://www.thealchemistscupboard.co.uk/page/capella%20recipes
I am pretty sure that's the recipe i used.
Capella's vanilla custard is diacetyl free! I mix mine at 10% vanilla custard and 8% cinnamon danish swirl. Might add some EM in it this time.
I might try that, or a modified version.. not a big cinnamon fan but I like it in small quantities, where there is just a hint of the flavor.. I'll try your version and if it's too much maybe a 14% with 4% or something along those lines. Thanks.
Don't rub it in:( Capellas vanilla custard is so hard to find on a Canadian site.
I emailed Capella asking them about shipping to Canada after my usual places were sold out. They referred me to: http://www.lowcarbcanada.ca/Capella-Flavor-Drops-Vanilla-Custard-0-4-fl-oz-p/cap064.htm . Looks like they have a lot of Capella drops I've not seen elsewhere too. I haven't ordered from here, but might in the future.
I lucked out and found some Custard at http://diy-ejuice.com/ later that day and picked it up with some other stuff too.
Please read this whole thing and don't use custard flavors.
tl;dr popcorn lung
Almost all vendors have stopped using diacetyl, including Capella.
Edit: The article you linked did not say 'don't use custard flavors'. Nor did it say you would get popcorn lung from custard flavors.
Popcorn lung is a condition that workers at popcorn factories got after a long term of high levels of exposure. Have there been any studies comparing levels found in e-cigs (possibly due to acetyl propionylm and/or acetoin catalyzing)? I couldn't find any. I did find a few articles claiming there was a lack of evidence that diacetyl had caused popcorn lung in either consumers of microwave popcorn or e-cigarettes, but I still couldn't find any articles citing any actual studies done.
Flavor vendors have stopped using it for e-cig products, either as a cautionary measure or just to get on the bandwagon. I am not sure which I believe.
And I am more skeptical as to articles I have read warning about diacetyl forming from acetyl propionylm and/or acetonin, at least in quantities that might actually cause popcorn lung, than I am about a tendancy of marketers or anti-ecig groups to get on any bandwagon.
/u/PejorativePenguin is right, it is something to be aware of. It is not, in my opinion, something to panic over.
I think I will continue to enjoy custardy flavors on occasion, possibly even promoting them to others as being tasty. Perhaps with a warning... but I'd hate to cause a panic over something I've seen no evidence for.
A longer tl;dr:
Inhalation of the chemical diacetyl (used for custard and buttery flavors) is known to cause bronchiolitis obliterans. Quoting wikipedia:
> Bronchiolitis obliterans is a rare and life-threatening form of non-reversible obstructive lung disease in which the bronchioles (small airway branches) are compressed and narrowed by fibrosis (scar tissue) and/or inflammation
Because of this some manufacturers stopped putting this in flavors used for vaping (or at least started stating whether or not the flavor contains diacetyl). This included TFA and Capella.
Another problem is that these custard, buttery, vanilla flavors also use acetyl propionylm and/or acetoin. These are able to catalyze into diacetyl. So even though a flavoring says "diacetyl free" there is the possibility that diacetyl is still present.
Are you going to get "popcorn lung"? Probably not. The amounts are going to be very small. However, it is something to be aware of.
still a lot less than you got from tobacco smoke. seriously- http://toxnet.nlm.nih.gov/cgi-bin/sis/search/a?dbs+hsdb:@term+@DOCNO+297

there is more found in cigarette smoke.
Is that really the point? This is totally avoidable.
Hey, thanks for the heads up.. I knew about diacetyl but had never seen the other ingredients to be wary of come up where custard's are discussed. I will keep this under consideration.
