Has anyone made a list of suggested steep times for certain concentrate? Such as Bavarian cream is 10 days?
Steeping, like the amount flavoring, is up to your taste buds. You may like something at two weeks that I like at 1 week and vice versa. Some like to heat steep, others ultrasonic, others shaking while standing on your left foot facing north. Me, I just let time do it's thing and when I get around to vaping a bottle is when it is done.
General rule of thumb is fruits S&V, creams and custards 1 to 2 weeks, tobaccos longer. But like anything with DIY it's up to you. Sample during the aging process so you know what works for you.
