Do they come bare bones like itc which require aging?
Well, I didn't get the 10ml samplers. My first order was the discontinued 60ml bottles, and my second was the 100ml bottles. Although I did receive a free 10ml sample with each order. The liquids are made to order, and shipped extremely quick, so breathing and steeping (and shaking) is just good practice. I did try each one within 24 hours after receiving them, and most were good to decent within that time. The custards and creams improve over time; the custards were a tad harsh FOOB, and are smoothing after a month. The creams blended and the fruits blossomed within a week; at one month, the creams really shine.
Only 1 or 2 were near perfect from day 1: Me Lucky Charm (cereal vape), and the 10 ml of banana fosters. But that's to my tastes. While Big D's Blueberry Custard has improved greatly, and I am currently vaping it, I do prefer DieselbyCG's Blueberry Custard. I waited a month before I tanked Blue Moo and Strawberry Blonde, but they were worth the wait.
Ohm's Vapes uses flavoring I wasn't familiar with, so it took a minute to get used to the bases used. Most showed promise within a day. The only ones I was worried about were the custards, and those are nearly steeped enough to my liking a month later, so steeping helps.
