RY4 Double | The Flavor Apprentice (20/50/100/250/500ml)

The Flavor Apprentice develops water-soluble food flavorings for DIY mixing. RY4 Double is a bolder, more concentrated interpretation of the classic RY4 profile, featuring deeper tobacco notes combined with pronounced caramel and vanilla sweetness. This highly concentrated flavor must be diluted before use. It is commonly used for robust RY-style recipes or diluted further to fine-tune strength. All TFA concentrates are PG-based and water-soluble. Note: We purchase in bulk and rebottle into smaller bottles (not original manufacturer packaging).
