Not sure if this helps anyone, but I’ve been testing different blueberry sour raspberry ice vape liquids lately because most either lack the “sour” part or go too heavy on menthol. Finally landed on a couple that actually balance all three notes pretty well. You get that slight tart hit first, then a cool finish—not overpowering. If you’re picky about flavor layers like me, you might wanna browse this section I came across: https://www.e-cigclouds.co.uk/product-category/e-liquid/?filtering=1&filter_product_brand=408 Saved me some trial and error tbh.
