I mixed up 15ml of watermelon… just 4 drops of flavoring in it. NOT peppery at all. Fresh watermelon with a bit of the rind. Or… the light pink part next to the rind. That’s what I get.

Apparently its just me. I just loaded up the batch I made 19 days ago. It’s completely smooth to me now. So apparently there’s something there I’m sensitive to. This is a good thing! I forgot to mention that I had taken this to MadVapes in Columbia and let the guys there try it. It was about a week old at the time and I didn’t mention the pepperiness I get. They raved about the flavor but no one mentioned any harshness.
I had even considered adding some Vape Wizard to this. Glad I didn’t.

Has anyone had any issues with the flavors getting weaker over time ?

This is a copy of what I have posted on UKVapers reposting it here if it is any interest to mixers on here?
Posting my reviews of the Medicine Flower extracts I bought direct from the manufacturer in America. These flavours are extracted from the actual fruit so are a natural extract with no added VG or PG mixed into the bottle of extract you purchase.
All 5 flavours I have mixed in an all AG base at 12mg and each flavour is mixed at 3, 4 and 5 drops per 10ml. I have made enough to sample a tankful of every strength over a 4 week period, so I will be able to see how they develop over that time.
All will be tested on Sigelei 75w TC mod and Uwell Crown Tank using a stock 1.2ohm Coil or 0.15 ohm coil to see how they compare at higher watt/temp control and lower watts
Week 1 Steep - All tested on 1.2 ohm coil at a range of 25w-33w, There has been little or noticable colour change except for a tinge of yellowness to the finished liquid after 1 week
Watermelon
You get the flavour of the sweet red part of the watermelon constantly along with an occasional slight sour rind taste in the background.
This makes it a well balanced flavour overall, but to be fair to the usual watermelon concentrates I have tried, the flavour after the first
week is very similar to say Capella Double Watermelon, but what is standing out with the MF concentrate is the natural sweetness of the fruit
that comes through. Occasionally found you get a slightly stronger hit of the sour coming through for a couple of vapes whilst vaping a full tankful of juice (comes as a bit of a shock). After week 1, I feel this flavour has a while to go before it reaches it full potential but preferring 3 drops at this early stage as it is seems to give a much smoother sweetened flavour overall at this stage.
Mango
This is so much like a mouthful of juicy ripe mango, it is smooth, naturally sweet and leaves a satisfying aftertaste on the tongue, amazing flavour. 3 drops and a one week steep and this feels ready to vape, but I will see how much more it can develop over the coming weeks. 5 drops has a slight bitterness to it so far, that reminds me more of the usual mango concentrates that I am used to.
Strawberry
Only a little flavour coming through, giving just a hint of a perfectly sweet and juicy fresh strawberry. May need to be mixed at a larger amount or needs a longer steep, will see how it develops over the coming weeks. 5 drops is preferred strength after 1 week.
Raspberry
Recognisable as raspberry, but very sweet, so comes across at this early stage as more like a raspberry syrup flavour. Hopefully it will develop that tang you get with the real fruit. At 3 drops plenty of flavour, may need to use less drops?
Guava
Never tried the real thing so can’t say how realistic it is, but Guava as a vaping extract in this range is superb, it has an acidity to it like a ripe juicy pear and the sweetness of a red berry in the same vape, absolutely gorgeous at 3 drops. All the other 4 flavours have been naturally sweet flavours and it is good to know that if I choose a cirtic/acidic flavour in the future, then there is a good chance it will have that sharpness you would expect from fruits such as these.
Will start a second test to cover the 2nd week of steeping over the next few days and post any changes/development of flavours before xmas hopefully.

It most certainly does! Thank you.

I havent but some have. I do not store in dropper bottles, i store everything in cone cap bottles. Dropper bottles will cause some flavor loss over time with anything stored in them.
I have some bottles curing, when i tested the 3 month bottles they were all quite beautiful. Still have a bit to go on the 6 month bottles.

I think i mentioned this before but i dont see this as any kind of stand alone, it is a pretty sour flavor just as the cherries it is derived from are. I think it will be a great mixer tho.

Something else that i forgot to mention along the way is that many people use their flavorings in the .5-1% range. My personal preference is usually less than what the majority use. I dont know how many of you have heard of OpenSourceVapor but they use MF flavorings in their mixes, not only do they sell the mixes but they post the recipes.
I had forgotten about their site but was reminded when reading through some DIY threads on reddit.

OSV… very good reading there. So these recipes are MF flavors?
Thanks for the link.

Yep, i do believe they are all MF flavoring tho i didnt look through them all but each one i did look at was MF. When they talk about reader or user suggested %'s some have suggested that this is for evod users or old tank style users and i agree. The highest % i have used any of their flavors at is 1.5% for banana tho i havent used Vanilla as they do. They use it as a cream type base, i use it for the flavor and smell. I am intrigued by this and have started jotting down some recipe idea’s to utilize it in the manner.
Anytime, wish i had thought of it earlier as i am horrible at answering questions sometimes, seeing the flavors in recipe probably would have been very helpful to everyone.

Just making sure - You’re mixing 10 ml of this right? 3 drops mango in 10ml liquid?
1 Like
Yes each flavour is mixed as a sample adding either 3 ,4 and 5 drops (using the dropper that MF supplies with the 15ml extract bottles) in a bottle that contains 10ml of 12mg AG base
I measured a ml of extract and made it 45 drops using the MF dropper (subject to me not going to cross eyed during the process of counting )
Due to the strength of these extracts in there undiluted form, I think measuring by drops will be the way forward for myself personally, when mixing with these, as I don’t use scales.
I don’t expect all of the 5 flavours to be perfect within these drops measurements and there may well be a need for some adjustment further on. But as I have learned from strong concentrates (tester for Inawera) if I use a starting point with consistent amounts when testing, it ultimately provides me with a good starting point when trying out new flavours.

Week 2 steep reviews
Tested on Uwell Crown stock 0.15 ohm coils at 475-510F 40-50w
Watermelon
Flavour has changed and the sweetness has died down and the watermelon natural flavour is really starting to come through. 3 Drops feels ready to vape but is a little weak in finished flavour. 5 Drops provides the right amount of strength of flavour in the vape for me, but due to being it stronger needs a bit more steeping I feel. Nice balance of red juicy fruit coming through with a slight sourness of rind coming through. Occasionally get an extra strong hit of rind when vaping and makes a nice contrast to the usual red fleshy part you get but still pleasant vape…
Mango
The flavour of the fruit has really come to the fore and the sweetness has subdued, with just an occasional hint of sourness, this is really coming across as the real thing flavour wise. Flavour comes through at 3 drops but 5 drops seems the perfect amount for my tastes. Feels as a 2 week steep is the minimum to get the right balance of flavour and sweetness for this particular extract in high vg mixes, but the change between 1 week and 2 week steep is amazing, so maybe there is more to come?
Strawberry
Feel I haven’t mixed this strong enough and this will probably need at least 10+ drops. I get the sense of what this flavour can give even at 5 drops though, the taste of real strawberry and the natural sugars shine through and gives such an amazing flavour representation, but just not at the strength I want. 5 drops feels good for a mixing level with other fruits but as a standalone I am going to try mixing it again using 8, 10 and 12 drops in the New Year
Raspberry
Recognisable as raspberry, sweetness level dropped back slightly but still quite sweet and syrupy overall, 3 or 4 drops seems a reasonable level to mix this at for a standalone, hopefully steeping a little longer will continue to reduce the sweetness level. At this strength of flavour and sweetness (4 drops) I can see 1 or 2 drops being plenty in a mix for my tastes.
Guava
This is developing into a real good flavour, the citric kick on it provides a great throat hit on the inhale and a really decent fruit tasting flavour on the tongue. 5 drops is my preference at this moment although strong it isn’t overpowering as a standalone. For mixing 1or 2 drops may well suffice.
Will hopefully post a 3rd update in the New Year to see how these flavours have developed over 4 weeks and will probably leave 10ml of each strength to steep for a further month so I can get a good impression of how these extracts develop over time.

OK…3 weeks exactly for steep…I mixed this Watermelon at 40/60 PG/VG @ 2%…Seems high, however, I am mixing these for a little Aspire eGo type tanks with the small surface area coil insert…MTL hitter…These tanks generally do not perform as well as RDAs for flavor…Can’t wait to get this into my Goblin Mini…My experience with Watermelon runs along the line of many reviews here on this thread…Vaping it as I type…By far, THE most tasty experience in my short (4 month) vaping career…and even shorter DIY experiences
Not a lot of flavor in the initial draw…but the inhale…flavor explodes in my entire mouth…Absolutely the red pulp of the melon is there, with a very slight bitterness at the top…Bitterness that I am experiencing may be the “rind sour” note that many of you describe…There is almost a sort of dryness associated with the aftertaste (much like the dryness of a wine)…
Exhale is equally flavorful, and there is a coolness with that as well…I enjoy hotboxing this, and breathing the vapor in and out…French inhale and exhale provides more of the rind essence…Very interesting experience…Draw into mouth…inhale with mouth wide open equals sweet spot with the exhale from mouth and nose…
Absolutely the most pleasurable vape I have had so far, barr none…Wondering if it gets better with age beyond 3 weeks steep time, so far…Any input out there on that?..Gotta get it into my Goblin Mini with air flow control…Given my mix percentage, I am certain that the flavor will be multiplied…
I bought these on a Lark, whilst visiting ECX and just opening my mind to different flavors from their offerings…ProVapes review forced me over the edge…

Just a quick update on all these flavours, they have all steeped now for 28 days at the various strengths mentioned in the earlier reviews, I posted.
I have seen and read in a couple of reviews elsewhere on the net, that the flavours die off a period of time and I am experiencing this now with the all the flavours I mixed except raspberry. That I bought and mixed earlier in December.
They now, have all, what I would describe a more rounded developed and recognisable flavour but overall have become much weaker, much less sweet and a little dank in finished flavour. i.e. the sourness and the sweetness of the watermelon at the same time has all but disappeared and left just a mouthful of weak tasting watermelon
I still have 10ml of each flavour at each strength I mixed left, so will leave them another month and re-check to see if it is a stage of steeping development they are going through at the moment? and if they come out any better for a longer steep.
There could be many reasons for this, I haven’t mixed them at a higher enough concentration level and they need more to maintain the flavour and make them last beyond 4 weeks? I steeped them all with lid off for 4 weeks and maybe that has impaired the final flavour? I used Max VG, this is all something I will have to look into, further along the line and mixing with other flavours and brands to see how they work in recipes.
Although what I have written may sound negative, I am still very positive about these flavours. I think for my own personal tastes, they are at there best 7-14 days after mixing due to the natural sugars and real fruit taste you get from them in the vape, I really can’t convey how good they were for me at that stage of development and is something that I have never experienced in 3 years of vaping with any other single flavour concentrate or juice before.
These and other flavours will definitely become my ADV but I will mix sensible quantities 20ml at a time as mixing large quantites will be just wasteful if they become so muted after 4 weeks for me personally at this moment in time.
p.s. I used 2 different makes of tanks and stock coils to test these on in case I had a dodgy coil and experienced the same final taste on both.
Hopefully a few other mixers will starting posting reviews elsewhere on the net over time as Medicine Flower become more popular and different techniques and ways of using these concentrates in mixes will become discovered. To get the most out of them.

Increase your PG ratio in the mix and I’ll bet you’ll see a world of difference; say around 40% PG. However, some flavors do fade over time; I’ve noticed that with some of my tobacco flavors, even at higher PG ratios in the mix.

Vaping PG and using PG in everday products is a real problem for me,
I have always mixed Max VG but have learned to tolerate the small amount of PG I have to use when mixing with concentrates, Hence the appeal of Medicine Flower concentrates.
The flavour profile changes from week 2 to week 4 for me and I thought it was poorer for it, but that is just my opinion. I don’t drink but it made me think when people talk about the difference between young fruity wines and matured wines. Maybe for me and my tastes MF and VG suit me better for a shorter steep time?
Certainly the 5 flavours I tried are better than anything else I have tried on the market currently and I will be happy to work with them in the timescales of steeping and vaping I need to, as they will definitely be worth the effort.
