Old Grand Dad 80 Proof is one of those bourbons that quietly punches above its weight. It's a brand with serious pedigree in the American whiskey world — named after Basil Hayden Sr., a distiller who was working with high-rye mashbills back in the late 1700s. That high-rye DNA is still the defining characteristic of Old Grand Dad today, and it's what makes this bottle stand out on a shelf full of wheated and low-rye competitors.
At 40% ABV, this is the entry point in the Old Grand Dad range, sitting below the Bonded (100 proof) and the 114 expressions. It carries the Kentucky Straight Bourbon designation, which tells you everything you need to know about the legal minimums: at least two years in new charred oak, made in Kentucky, at least 51% corn in the mashbill, and distilled at no more than 160 proof. But the real story here is that rye content. Old Grand Dad has always been known for pushing the rye percentage higher than most bourbons, and you can feel it. There's a spice and a backbone to this whiskey that you simply don't get from something corn-heavy and sweet.
This is a NAS (no age statement) bourbon, which at this price point is perfectly standard. What matters more than a number on the label is what's actually in the glass, and Old Grand Dad 80 delivers a clean, well-structured pour. It's not trying to be a barrel-proof bruiser or a single-barrel showpiece. It knows what it is: a solid, everyday bourbon with character.
Tasting Notes
I don't have my detailed tasting notes to hand for this particular bottling, but I can tell you from experience that the high-rye mashbill gives Old Grand Dad a profile that leans toward baking spice and pepper rather than caramel sweetness. If you're used to wheated bourbons like Maker's Mark, this will feel noticeably different — drier, more assertive, with a bit of snap. At 80 proof it's approachable, though I'll admit the Bonded expression gives you more to work with if you want the full experience.
The Verdict
At £52.75, Old Grand Dad 80 Proof sits in a competitive space. You're paying a slight premium for a bourbon that's widely available in the US at a fraction of that price, which is the reality of importing American whiskey to the UK. That said, if you're specifically after a high-rye bourbon at an easy-drinking proof, your options on this side of the Atlantic are genuinely limited. Old Grand Dad fills that gap well. It's honest whiskey — no gimmicks, no flavour additions, just a well-made Kentucky straight bourbon with a distinctive grain bill. I'm giving it a 7.7 out of 10. It loses a fraction for being slightly thin at 80 proof compared to what I know the distillate can do at higher strengths, but it gains points for consistency and that unmistakable rye-forward character that makes it genuinely useful both neat and in cocktails.
Best Served
This is a cocktail bourbon, full stop. That high-rye spice makes Old Grand Dad 80 an absolute weapon in an Old Fashioned — the pepper and baking spice cut through the sugar and bitters beautifully, giving you a drink with real structure rather than a syrupy mess. It's also brilliant in a Whiskey Sour, where the grain character holds its own against the citrus. Neat, it's perfectly pleasant but a little light. On the rocks with a single large cube, it opens up nicely for a casual pour. If you're building a home bar on a budget and need one bourbon that works across cocktails and sipping, Old Grand Dad 80 is a smart choice.
