The Engineer Series Concept
Echo Spirits has built their reputation around precision blending, and Batch 25C exemplifies their engineering approach to whiskey making. The “Won’t You Bee My Neighbor?” release demonstrates how thoughtful component selection can create harmony from complexity. The decision to finish 38.4% of the blend in pear mead barrels for seven months shows real creativity, while the remaining components provide the backbone structure needed to support that innovative finishing.
Production and Blending Details
This batch breaks down into three distinct components, each contributing something different to the final product. The largest portion comes from Bardstown Bourbon Company – a 75% corn, 21% rye, 4% barley mashbill aged 6 years and 8 months, then finished in pear mead barrels for an additional 7 months. The second Bardstown component uses a higher-corn mashbill (78% corn, 10% rye, 12% barley) aged 6 years straight. The MGP contribution brings an 8-year, 4-month wheated bourbon (51% corn, 45% wheat, 4% barley) that likely provides the smoothness balancing the rye heat.
Appearance and Color
Pour this bourbon and you’re greeted with a deep amber that hints at its 6+ year age statement. The color has richness without being overly dark – exactly what you’d expect from properly aged bourbon that hasn’t been over-oaked. The legs form medium and move slowly down the glass, suggesting good viscosity from the higher proof and age combination.
Nose
The pear mead barrel influence announces itself immediately with distinct grape and raisin aromatics that you don’t typically encounter in bourbon. Fresh pear follows, creating an almost wine-like quality that’s both surprising and pleasant. Underneath the fruit-forward character, classic corn and grain notes provide the familiar bourbon foundation. The nose suggests the complexity you’re about to experience – this isn’t your typical Kentucky straight bourbon.
Tasting Notes
The palate delivers on the nose’s promises with an interesting progression. Lemon custard leads the charge, providing creamy sweetness that plays beautifully against the 118.4 proof heat. The corn influence that the reviewer noted comes through strongly, giving this bourbon a solid grain backbone. Pear continues from the nose, but it’s more integrated here – not competing with the traditional bourbon flavors but enhancing them. The wheat component from the MGP juice seems to be doing its job, smoothing out what could have been aggressive rye spice into something more manageable.
Finish
The finish runs short to medium length, which might disappoint some high-proof bourbon lovers expecting longer development. Oak emerges here along with lingering sweet notes, while the heat builds and holds. It’s a satisfying conclusion that doesn’t overstay its welcome, though you might find yourself wanting just a bit more complexity in the fade.
Who Should Buy This
This bourbon appeals most to whiskey drinkers who enjoy innovative finishing techniques and aren’t afraid of higher proofs. If you appreciate fruit-forward whiskies or have enjoyed other alternative barrel finishes, Batch 25C offers something genuinely different. The corn-forward profile makes it approachable despite the proof, while the unique aromatics will appeal to collectors and enthusiasts looking for conversation-starting bottles. However, traditionalists seeking classic bourbon profiles might find the pear mead influence too unconventional.
Where to Buy
Finding Echo Spirits Engineer Series releases requires some hunting, as they’re limited production runs typically distributed through specialty retailers and whiskey shops. With only 460 bottles of Batch 25C produced, availability is extremely limited. Check with local craft spirit retailers, whiskey-focused bottle shops, and the distillery’s official channels for release information. Expect to pay premium pricing for this type of limited, innovative release, though specific retail prices weren’t readily available through standard channels.
FAQ
What makes this bourbon different from standard releases?
The combination of three different mashbills from two distilleries, plus the pear mead barrel finishing on one component, creates a unique flavor profile not found in traditional bourbon releases.
Is 118.4 proof too hot for most drinkers?
While it’s definitely high proof, the wheat component and fruit-forward character help balance the heat. Adding a splash of water can open up the flavors if you find it too intense neat.
What’s the significance of the different mashbills?
The three components each contribute distinct characteristics: the rye mashbill provides spice structure, the high-corn Bardstown brings sweetness, and the wheated MGP adds smoothness to balance everything.
How does pear mead barrel finishing work?
After initial bourbon aging, a portion of the whiskey spends additional time in barrels that previously held pear mead, picking up fruit and honey notes that complement the bourbon’s natural flavors.
Should beginners try Engineer Series bourbon?
The 118.4 proof makes this challenging for new bourbon drinkers, but those with some high-proof experience who want to explore innovative techniques will find it educational and enjoyable.
Final Verdict
Echo Spirits Engineer Series Bourbon Batch 25C earns 3.5 out of 5 stars for its innovative approach to bourbon blending and finishing.
