As far as P.I.T.A what does that mean? Also what does make their own extractions mean?
Thanks for the help!
P.I.T.A. someone already answered.
Make their own extractions: Many ejuice vendors create their products with commercially available flavor extracts that anyone can buy. That means if you choose to "do it yourself" you can order the exact same flavors from Lorann or Flavor West and create it yourself.
Making your own extractions means that not only does the ejuice company create the liquid but they create their own flavor extracts as well. Basically like making your own vanilla flavor extract instead of going down to the grocery and buying some random mediocre vanilla extract off the shelf. By creating their own flavor extracts an ejuice maker can better control what goes into making the flavor and tailor it to their own needs.
Say you buy an apple flavored eliquid from vendor "A" and don't like it. You then go to vendor "B" and try their apple eliquid and don't like it either. Same thing with vendor "C." The common thread between them may be that they all use an apple extract from the same company possibly causing you to think all apple ejuices are bad.
When I think of vendors that create their own flavorings the first company that comes to mind is Ahlusion. Ahlusion makes around 80% of all their flavorings in house which means their cherry flavors aren't medicinal because they create it from local Michigan cherries. Making their own flavor extracts also means the company has put a bit more time and effort into creating a quality product for their customers.
Hope that helps.
edit: Making their own extracts also most likely means the vendor is making them from the actual substance (fruit, berries, tobaccos, etc.) instead of a big company just mixing up chemicals that simulate the taste of a particular flavor.
