Holy Grail RY4 V2 Concentrate (DIYFS)

Delicious caramel tobacco flavor

Delicious caramel tobacco flavor

Ah, the legendary Holy Grail RY4 V2 (DIYFS) — 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 they’re candy, too much tobacco and they’re 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 here’s the verdict.

🐐 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 — in a good way.

Flavour Profile (In Vape)
Inhale: Smooth caramel up front with just the right amount of vanilla cream trailing behind. There’s a warmth that rolls in — 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. It’s 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 — impressively balanced.

Mouthfeel: Dense and velvety.

Label Accuracy:
Yep — this is a holy grail-tier RY4. Everything is in harmony: caramel, vanilla, and tobacco all playing nice. No single element steals the show. It’s 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.

Standalone Rating: 9/10

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 you’ve got yourself a fireside masterpiece.

Versatility Rating: 8.5/10

🐐 Overall Goat Score:
9.5/10
Holy Grail RY4 V2 (DIYFS) isn’t just another RY4 — it’s a grail worth chasing. The Old Goat says: this one earned its crown. Rich, smooth, and damn near perfect right out of the bottle.

Perfect base for tobacco mixes. 5% plus tobacco additives and Acetyl Pyrazine provides excellent tobacco flavor.

Great flavour! Sweet vanilla/caramel tobacco.

Best RY4 Desert by far, use this one at 5% or more. It is nice as a shake and vape, but gets better and better after 4 days steep.
