I change my flavors up when it's really hot or cold.
In the winter I want more rich flavors - full-bodied tobaccos, coffee, chocolates, caramels, pumpkin, etc.
In the summer I lean more towards the lighter side - fruits and citrus, honeysuckle, teas, etc.
I happily vape menthol and mints year-long, and I do vape a variety of flavors all the time, but I crave different things more during the different seasons.
