1. Historical Context

Grant's is one of the world's most recognised family-owned blended Scotch brands, with a heritage stretching back to 1887 under William Grant & Sons. This 100 Proof Superior Strength bottling is a product of the late 20th century (likely 1980s-1990s) and reflects a popular industry trend: producing higher-strength variants of core blends exclusively for the Travel Retail (TR) and high-proof export markets.

The decision to bottle at 100 US Proof (50% ABV) instead of the domestic 40% ABV was strategic. This elevated strength provides a significantly more robust, rich, and intense experience of the standard blend, a quality highly valued by consumers seeking maximum flavour retention, particularly in the duty-free environment. The 1 Litre size further confirms its origins as a Travel Retail exclusive.

The Grant's blend relies heavily on malt components from William Grant & Sons' own distilleries, such as Glenfiddich, giving it a distinctive house character that is generally fruity and light, though intensified by the 50% ABV. This specific bottling is a tangible piece of pre-millennium Travel Retail history, demonstrating the brand's willingness to cater to consumers who prefer a more powerful expression of their classic blend.

2. Technical Specification & Variant Map

The Grant's 100 Proof is technically defined by its adherence to the specific high-proof requirement of certain export markets.

• Volume: 1 Litre (100cl). The large volume is a hallmark of Travel Retail.

Variant Matrix:

2.2 Packaging & authenticity checklist

• Labelling Cues: The label must prominently display "100 Proof" and "Superior Strength." The 1 Litre size is a key verification marker.
• Closure: Typically a standard screwcap for high-volume blends.
• Condition Note: A high fill level is necessary to validate that the full 1 Litre of high-strength liquid remains intact, particularly given the age and closure type. The outer packaging is often a simple box or tube.

2.3 Regulatory/terminology notes

The liquid is legally defined as Blended Scotch Whisky. The liquid is a combination of single malt and grain whisky, with the single malt component sourced from the William Grant & Sons distillery portfolio. The high 50% ABV is classified as "Superior Strength."

3. Liquid Profile (from verifiable notes)

The tasting profile benefits significantly from the elevated 50% ABV, delivering a rich, enhanced experience of the standard Grant's blend.

Nose: A rich base of barley malt, vanilla, and toffee is present. The nose is further lifted by notes of apples, pears, and orange peel, moving toward dessert-like aromas of banana pudding and biscuits. Subtler tones include white pepper, hay, and distinct oak notes.

Palate: The arrival is slightly alcoholic, providing a noticeable richness. Flavours include sweet cereal flakes, vanilla, and honey. Dessert notes continue with banana cake and baked apples, all complemented by a light dusting of sugar and a pinch of pepper. The mouthfeel is generally described as smooth and rich.

Finish: Medium long. The conclusion is persistent with notes of caramel, vanilla, and sweet cereal, followed by stewed fruit, oak, and a lingering pinch of pepper.

With water: Not stated by the producer.

4. Distillery/Bottler Snapshot

William Grant & Sons, founded in 1887, is one of the few large Scottish distillers that remains fiercely independent and family-owned. The company is known for its vertical int�tion, owning significant single malt distilleries (Glenfiddich, The Balvenie) whose malts form the backbone of the Grant's blended Scotch brand. The house style is focused on approachability, smoothness, and a consistent level of quality, with the 100 Proof variant providing a powerful, yet balanced, expression of this legacy.

6. Sourcing:

• Target formats/eras to prefer: Exclusively the 1 Litre, 100 Proof (50% ABV) bottling for volume and superior liquid strength.
• Red flags: Bottles lacking the "100 Proof" designation are the standard 40% ABV and should be avoided.
• Condition thresholds (fill/box): High fill level is important given the old screwcap closure. Original packaging is a bonus but not critical.
• Margin/velocity expectations (qualitative): High velocity expected due to low price point. Margin is moderate based on the 40.00 GBP retail ceiling.
