Flavor-Neutral THC Oil Lets the Flower Stay in Charge

[Riff]

Flavour neutral THC oil is cannabis distillate which has been refined to strip out the inherent taste and aroma. It's produced via fractional distillation which separates the cannabinoids from the aromatic compounds, followed by filtration to remove the plant waxes, chlorophyll and lipids. It doesn't produce a truly neutral product as such (the flavour of the carrier oil and the residual cannabinoids will still be there to some extent), it just removes the plant derived flavours and aromas. The level of refinement and what 'flavour neutral' actually means tells you a lot about the process of manufacture.

What Is Flavor-Neutral THC Oil?​

Flavours neutral THC oil is just cannabis oil (typically a refined distillate) which has been processed to take out the taste and smell of the plant. It's not oil that's been flavoured with terpenes or other flavouring agents. The neutral oil is produced via an extraction process which removes the plant compounds which are responsible for the taste and smell, resulting in a concentrate which is essentially there for its potency rather than for its flavour.

This is important because neutral oil doesn't compete with the characteristics of the flower. When you put neutral oil with flower it doesn't fight the flower's profile at all. The strain's own aroma profile is what you end up with. The comparisons with the flavoured and terpene infused oils are very clear in this respect. Neutral oil is a very flexible product as it will allow for a whole range of consumer preferences as it's a very neutral product and doesn't have a profile of its own. It's the flower that defines the product.

How Refinement Strips the Taste Out of Oil​

Getting the oil to that quiet, compositionally neutral state is more than just extraction. It requires targeted refinement. The various extraction methods (distillation, CO2 etc) will extract the cannabinoids from the plant material, but they will also leave behind the plant lipids, chlorophyll and the native terpenes which will impart flavour and aroma to the final product. The refinement processes are specifically designed to deal with that. Fractional distillation will separate the cannabinoid compounds from the volatile aromatic molecules and filtration will remove the plant waxes and pigments which will impart flavour. It's the opposite of a flavour extraction process where you're trying to extract and preserve the terpenes. Here you're trying to remove the terpenes. There is no terpene preservation or aroma retention at all. The aim is subtraction not addition and you're left with a cannabinoid base which has very little of its own sensory footprint.

What "Neutral" Doesn't Mean​

How far you go with refinement is important because 'neutral' doesn't mean 'flavourless' or 'inert'. A flavour neutral THC oil is one that has been formulated to have as little of its own taste and aroma as possible, not one that is totally devoid of any sensation. Setting out with neutral flavour expectations means you have to accept that there will still be a degree of warmth, a touch of bitterness or a very faint vegetal note from the base oil itself. A comparison of different extraction methods will show that distillate for example will have a very different profile of residual compounds to other oil refinement methods and hence will taste very different in the base. Understanding aroma profiles is key to realising that neutrality is a spectrum rather than a yes/no proposition. Consumer preference is all over the place so what is neutral to one person may well be very much in evidence to another.

Neutral vs. Terpene-Rich and Flavored THC Oils​

Once the limits of 'neutral' are clear then the comparison with terpene rich and flavoured oils is much easier to make. Terpene rich oils are produced via a process which is designed to preserve the terpenes (the cannabis derived compounds that give the plant its characteristic flavours and aromas). Flavoured oils take it one step further and will incorporate additional terpenes and/or flavourings to create a specific flavour profile which is completely independent of the flower. The flavour neutral oil is the other way around with the extraction and refining process being geared towards minimising the oil's own flavour contribution and thus leaving the terpene profile of the strain itself as the primary sensory input when used with the flower.

Product comparisons come down to consumer preference. If you're after some extra complexity of flavour then you'll probably go for a terpene or flavour rich product. If you're after the characteristic of the strain then you'll probably go for a neutral product.

Reading the Label and COA on Neutral THC Oil​

Why believe a label on its face when you have a Certificate of Analysis to prove it? The first thing you look at is the ingredient list. Carrier oil, cannabis extract and any other additives should be there in full and clear. There should be no 'other ingredients' or 'various' or any such vagary. Ingredient transparency is absolutely key if you're claiming to be a flavour neutral product as you could easily be full of terpenes and other flavouring agents that you've just not listed.

The COA goes beyond just marketing speak. It should confirm potency (THC %), test for any contaminants (pesticides, residual solvents etc) and ideally will have the terpene profile (even if that's just a few parts per million). Matching the label claims against the COA is a great way to validate the product and educate the consumer. A neutral oil backed up by a current, batch specific COA is not just plain, it's verifiable.
