Harsh Coffee Extract

[Soignee]

So I produce my own Coffee extract and I get a really rich strong Coffee flavor, very bold, which is what I'm looking for. So no problem with enough flavor. I extract it into VG. My finished juice is typically 60/40 vg/pg. The Coffee extract is 6% of the total flavor, with 15.75% total flavor in the finished juice. Other flavor components include custards, chocolates, vanillas etc...no other flavor components go above 3%

My issue is the finished juice can be really harsh, but not a TH harsh. I taste test at around 9 watts dual coil at .7 ohms in a TOBH on Rayon. Reducing wattage does not get rid of the harsh, but increasing wattage makes it way worse.

My question is, would ordering some F'art MTS help with this? I'm aware of it's use in Tobacco's, but haven't begun to dabble with them yet so I have no point of reference. Opinions please and thank you!

I have no clue as to why there is a harshness. Sorry.

May I ask the reason why you are making your own? No good coffees out there? I was thinking that I wanted to find a good coffee juice.

BTW.. nice Mikey avatar. He is missed

Just a hunch but maybe your extract needs to be filtered a bit more. VG is difficult to work with when trying to filter out organic matter and it may be burning on the coil creating a harsh vapor. Maybe try a 20ml syringe and push the extract through a finer filter media.

Yeah, Jerry too! Good to see family here...

I make my own because 1) I can. So I can control it. 2) I haven't found a good one. 3) I love coffee, I'm a Chef and I have access to lot's of good coffees so I can play around with it. If I could extract fruits etc...EASILY, I would.

Let me know if you find a good coffee though, I'm open to suggestions!

Thanks Az,
Makes sense! I think you are on to something. It is super gunky, so there may be too much particulate in there. I'll look in the extraction forum after work for media unless someone has a handy link.

Take a minute and glance at my blog. I make my own coffee flavoring and I have had good results. My simple recipe is there, also.

That's where I got the original extract recipe from I believe, might have been the original in the extracts forum, but same process I just use VG. I used your recipe as a base and have tweeked it a bit from there...

So thanks for the original inspiration! I have tried a lower % of extract in the recipe, doesn't give the Coffee punch for me and 6% is the sweet spot.

I just need to trouble shoot the harshness now. Maybe I'll have to live with it. Damn fine Coffee flavor though!

I'm not so sure it's the mix. I think your still running to hot even at the lowest setting. Coffee does not play well with hot coils. Try wrapping a 1.2 or 1.8 coil and see if that makes a difference. The extra filtering is also an excellent suggestion. If your coil is gunking up quickly that is also an issue of to hot a coil or the flavoring not being clean enough.

Thanks Danny, I will do a fresh coil when I get home. I'll start there and do a fresh filter and see what happens.

This is 1ml on the way to work! Sorry for the crappy pic.

I will keep trying to find a good coffee flavor.

I wish you good luck in your trials, sounds like some good advice to this noob.

Never got to hang out with Jerry but I did with Mikey a couple of times...super nice dude.

Yea it's deposits from poor filtering of the extract. Coffee is a pain in the .... that way. You really need to filter it well. Also a cooler coil will help reduce how fast it builds up but there is no getting away from it with extracts. Tobacco extracts have the same issue if not filtered properly. It's one big balancing act between filtering and taste. To much filtering, to much coffee used in the extract, to much flavoring used and you wind up with bad coil gunk, To little coffee or over filtering leads to a tasteless mix. It's a pain to get right. Either way you'll find yourself rewicking and recoiling much more often then with manufactured flavoring.

Thanks Danny and everyone, this is my first run with my own extract so I'm in that learning curve. I dropped a coil out last night but even at 1.3 it's still harsh, so I'll push this through a syringe and should see better results. I'm prepared for more dry burning. The flavor is just head and shoulders above commercial flavors so it's worth it.

I feel it's a win to go through additional filtering rather than using an additive, less $ down the road and less experimenting to fit the additive into the recipe!

Thanks for everyone's input!

Thanks Shaneguide,

All the Boys are awesome, we have hung out with JB and his wife a couple of times and they are really down to earth folks. Mikey's passing has been a real blow to everyone. They did find a quality replacement in Jimmy though...

Enough derailment...

Have you tried the Inawera Coffees yet? I sort of gave up before I tried that brand and I'm a big fan of Inawera.

 

[Shaneguide]

I will have to check Inawera out. Thanks for the heads up.

Agree.. the White Wizard is a much better replacement for Mikey than George was
