# Plum: Wine-by-the-Glass Technology Pioneer

High-Level Overview

Plum is a hardware and software company that created the first fully-automated appliance for wine preservation and service by the glass.[1][2] Founded in 2017 and based in Dania Beach, Florida, Plum develops a high-design wine appliance that holds two standard bottles, automatically identifies wine varietals using artificial intelligence, maintains each bottle at its ideal serving temperature, and preserves wine for 90+ days.[2] The company serves hospitality venues (hotels, resorts) and luxury home developers, with partnerships including Four Seasons, St. Regis, Waldorf Astoria, and Conrad.[4] Plum's core problem-solving proposition is transforming how people experience wine by the glass—enabling single-touch service while maintaining wine quality and freshness, a capability that didn't exist in the appliance industry before.

The company has demonstrated significant growth momentum, expanding from hospitality into residential markets and aggressively pursuing international expansion. In the past six months (as of the reporting period), Plum began selling in Mexico and the Caribbean with pending deals in Asia and Europe.[2] The company reported $5 million in revenue and employs 26 people.[4]

Origin Story

Plum was founded in 2017 by David Koretz, who identified a gap in how wine could be enjoyed at home and in hospitality settings.[2] The founding insight was straightforward but innovative: existing wine service methods didn't preserve opened bottles effectively or allow for convenient by-the-glass service at the quality level winemakers intended.[4]

Koretz led the company through its early phase, establishing partnerships with luxury hotel chains and building the technical foundation. A pivotal moment came when the appliance achieved national and global sales traction, prompting Koretz to recognize the need for experienced leadership to scale distribution internationally. In a leadership transition, Koretz moved to Chief Product Officer and Chairman while bringing in Michael Traub, an appliance industry veteran, as CEO to drive global expansion.[2]

Core Differentiators

• Hardware-Software Integration: Plum merged hardware, software, and AI into a single appliance—a rare combination in the wine appliance category that delivers an integrated user experience.[2]

• Proprietary Preservation Technology: The company developed industry-leading technology for preserving and dispensing liquids, enabling wine to remain fresh for 90+ days after opening.[1][2]

• Embedded Software Ecosystem: Plum built a suite of software including embedded systems for interactive touchscreens with over-the-air update capability, remote diagnostics, and image recognition for wine identification.[1]

• Design-Forward Approach: Unlike traditional countertop appliances, Plum's design allows integration into cabinetry or freestanding placement, appealing to builders, designers, and architects who prioritize aesthetic integration.[2]

• Strategic Partnerships: The BSH Home Appliances partnership positions Plum to leverage a major manufacturer's distribution, quality standards, and kitchen innovation expertise to develop future smart appliances.[1]

Role in the Broader Tech Landscape

Plum operates at the intersection of smart home appliances, IoT, and hospitality technology—three converging trends reshaping consumer durables. The timing is significant: luxury hospitality and high-end residential markets increasingly demand differentiated amenities and integrated smart home experiences. Plum's AI-driven appliance taps into broader adoption of machine learning in consumer devices while addressing a specific, underserved niche.

The company's partnership with BSH Home Appliances signals broader industry recognition that innovation in kitchen appliances requires merging hardware craftsmanship with software sophistication—a shift away from purely mechanical design. By proving that wine service could be automated intelligently, Plum has demonstrated a template for reimagining other kitchen appliances through technology.

Internationally, Plum's expansion into Mexico, the Caribbean, Asia, and Europe reflects how luxury hospitality and residential markets are globalizing, and how niche appliance innovation can scale across geographies when backed by strong distribution partnerships.

Quick Take & Future Outlook

Plum is positioned to evolve from a specialized wine appliance company into a broader smart kitchen appliance innovator. The BSH partnership suggests the company's intellectual property around liquid preservation, software architecture, and AI-driven appliance control could extend to other beverage and food applications—coffee systems, beverage dispensing, or temperature-controlled storage.

The key inflection point ahead is whether Plum can translate its hospitality success into mainstream residential adoption. Luxury home developers represent a bridge market, but scaling to broader consumer appeal will require balancing premium positioning with accessibility. Michael Traub's appointment as CEO signals confidence in navigating this transition through distribution expertise.

As smart home ecosystems mature and consumers demand more integrated, AI-enabled appliances, Plum's early-mover advantage in merging hardware, software, and AI within a single appliance category positions it as a potential blueprint for the next generation of kitchen innovation.
