Does steeping subdue flavors that are too strong? (too strong as in too much flavor added)
Can you throw us up a recipe that went bad? If we know the flavorings, brands and the percentages it would help.
Or are you talking about a "ready-mixed" liquid you bought that tastes too strong?
I own a hand-held milk frother I picked up from Bed Bath and Beyond. I will now be using that to get air bubbles into my juice for steeping.
I use a milk frother as well and it does seem to speed up the steeping, though I'm not sure if it's because of getting air into the mixture or it's because it does a really good job of mixing the ingredients and breaking down the existing bonds so that new bonds can be formed between the PG/VG/Nic/Flavours.
and when you finish steeping your juice... be careful when you smoke it
Also using the milk frother fills the room with whatever flavours you're using, so there's definitely volatile compounds being released by using it.
