How to choose alcohol solvent for organic extraction?

Assuming I have an organic substance that is known to be "soluble in alcohol" (e.g. [capsaicin](https://en.wikipedia.org/wiki/Capsaicin)) I want to extract, *which* alcohol should/can I use? I know that both ethanol and methanol are commonly used, but what about:


* isopropanol
* glycerol
* n-Butanol
* 1,4-Butanediol
* tert-Butyl alcohol
* 1-Pentanol
* tert-Amyl alcohol


In general, which alcohols are suitable/unsuitable for organic compound extraction (e.g. which should be the best solvent in terms of amount of solute dissolved in given volume of solvent), and why? Is there any *a priori* way to determine e.g. if isopropanol extraction will be OK for a given "soluble in alcohol" organic substance?

Note: I am aware of [this discussion](https://www.researchgate.net/post/Which_is_the_best_solvent_for_herbal_extraction), but it doesn't cover the specific nature of alcohol extraction.




The optimal solvent will extract the greatest amount of desired product and the least amount of difficult-to-remove substances.


The extraction is only the first step; separation from solvent and other extractives follows. Try one, then another solvent to see if there is a difference. Maybe number of carbons or hydroxyls is important; you can also mix alcohols, and/or add water. 


Capsaicin has a phenolic group; perhaps it would be extracted from its source with alkali (NaHCO3 or Na2CO3).
