You guys are thinking about methods that are way too complicated, for me, for how to organize your flavorings, know which ones you've got, and be able to locate each 1 quickly. When I first started DIY, and got my first 25 vials of flavorings from WL...I thought about many of the ways you all have mentioned, to start organizing them. Then I thought, but what happens as I keep getting more and more flavorings? Won't I have to redo whatever system I've thought of so far...to allow for the addition of those new ones? Finally dawned on me - Just use a paint marker to number the tops of each bottle, vial, etc., as I get them. Make index cards with lists of the number and name of each flavoring...and tape those to the inside of my flavoring case lids, that contain those flavorings. That way, when I flip the lid up...I can quickly scan down the cards to locate the flavoring and number, then pull that bottle/vial of flavoring out. Easy to replace it when I was finished with it, too. When I started finding more recipes I liked, it finally dawned on me that my set-up could be made even easier. So, I started putting the flavoring's number beside the flavoring name on my recipe cards. That way, I didn't even have to scan down the index cards on the lids when I wanted to find those flavorings I needed. I just take my recipe card to the cases, flip up the lids, and pull out all the numbered vials/bottles I need. Even for a 6-7 flavoring recipe...I can have all of them pulled in about 5 seconds. I hope I explained that so it made sense. I was hurrying to get it written & posted before yet another 30-40 posts are made...and you all are WAY past any posts about organizing flavorings!
