Ah, the legendary Holy Grail RY4 V2 (DIYFS) โ a name that sounds like it should come with glowing clouds and angelic choirs, or at least a leather armchair and a tumbler of bourbon. RY4s are tricky business: too much caramel and theyโre candy, too much tobacco and theyโre ashtrays. But this one claims to be the holy grail of balance. Does it live up to the myth, or is it just another knight in rusty armor? The Old Goat took a long, thoughtful hoof-drag and hereโs the verdict.

๐ Aroma (Raw Sniff)
Warm, sweet, and rich. You get that classic RY4 caramel-vanilla blend with a subtle but present whiff of cured tobacco in the background. Like sniffing a dessert in a humidor โ in a good way.
Flavour Profile (In Vape)
Inhale: Smooth caramel up front with just the right amount of vanilla cream trailing behind. Thereโs a warmth that rolls in โ not harsh, just full-bodied and rich.
Exhale: The tobacco rises gently, never sharp or dry, just a soft, earthy undertone that gives the whole thing structure. Itโs not a cigarette, more like tobacco blended into dessert.
Aftertaste: Creamy caramel with a whisper of tobacco. Lingers like a good story.
Sweetness: Medium
Off-notes: None โ impressively balanced.
Mouthfeel: Dense and velvety.
Label Accuracy:
Yep โ this is a holy grail-tier RY4. Everything is in harmony: caramel, vanilla, and tobacco all playing nice. No single element steals the show. Itโs elegant, smooth, and satisfying.
Accuracy Rating: 10/10
Standalone Usability:
Absolutely. This one can fly solo all day without getting boring or overwhelming. Dessert tobacco done right.

Mixing Versatility:
Plays well with nuts, creams, custards, and a hint of spice (cardamom, anyone?). Great as a base or centerpiece. A few drops of Oakwood (FA) or Bourbon (FLV) and youโve got yourself a fireside masterpiece.
