I've seen quite a few people here saying that darker juices will burn/gunk up coils faster. I haven't had a chance to go browsing in any brick and mortar shops yet, and most of the (canadian) supplier sites that I've browsed don't actually show the bottles.
So, do certain flavour groups tend to be darker? If so, which?
