Short Stuff: The Guinness Widget

By iHeartPodcasts

This episode explores the origin and workings of the Guinness "widget," a patented innovation that allows canned Guinness stout to replicate the creamy texture and cascading pour of a freshly tapped cask. The widget's name stems from a generic manufacturing term that Guinness later adapted.

The blurb describes how scientist Michael Ash discovered infusing nitrogen, rather than carbon dioxide, creates the signature smooth mouthfeel and dense head. It explains how the widget captures nitrogen and allows it to release upon opening, aerating the beer and recreating the pub-pour experience at home. The blurb also notes other nitrogen-infused stouts using similar widget technology.

1-Page Summary

The Origins of the Guinness Widget

"Widget" Initially a Generic Term

The word "widget" first appeared as a generic placeholder for a manufactured item in a 1924 play, according to the summary.

Guinness Patented Widget to Create Draft-Poured Experience

Guinness later adopted the term and patented the "widget" - an innovation to recreate the creamy texture and distinctive pour of a cask-poured Guinness stout in canned form.

How the Widget Works

Ash's Discovery: Nitrogen Creates Signature Texture

Guinness scientist Michael Ash discovered that infusing beer with nitrogen, rather than just carbon dioxide, creates the creamy texture and cascading effect of a freshly poured draft, the summary states.

Nitrogen-Infused Widget Creates Head and Mouthfeel

The small plastic widget in each can captures nitrogen and beer during canning. When opened, it releases nitrogen, forming smaller, more stable bubbles that result in the iconic creamy head and smooth mouthfeel, according to Chuck Bryant.

Canned vs. Bottled Guinness

Bottled Lacks Nitrogen Infusion

Bryant explains that bottled Guinness lacks the nitrogen infusion of cask or canned versions, resulting in a notably different taste and sensation.

Widget Mimics Cask Experience in Cans

The widget allows canned Guinness to offer a similar smooth, non-fizzy texture to cask-poured drafts, making it distinct from the bottled version, Bryant notes.

Other Beers Using Widget Tech

Nitrogen Stouts Like Boddingtons Use Widgets

Bryant and Josh Clark mention other nitrogen-infused stouts like Boddingtons, Murphy's, and Old Speckled Hen that use widget technology for a creamy home pour.

How Widgets Aerate Beer

Bryant describes how the widget creates a "mini-jet" upon opening, aerating the beer to produce the desired texture and head, mimicking a pub pour.

Clarifications

  • The Guinness widget, found in cans of Guinness stout, infuses the beer with nitrogen when the can is opened. The widget contains a small amount of nitrogen under pressure, which is released into the beer upon opening. This process creates tiny bubbles in the beer, giving it a creamy texture and a smooth, draught-like pour. Th ...

Counterarguments

  • While the Guinness widget is innovative, it may not perfectly replicate the exact experience of a draft pour due to differences in the canning process and the environment in which the beer is consumed.
  • Some beer purists argue that the widget cannot fully capture the nuances of a cask-poured beer, which can include the temperature, the skill of the bartender, and the atmosphere of the pub.
  • There is an environmental consideration where the addition of widgets to cans increases the materials used and potentially impacts the recyclability of the can.
  • The widget's introduction of nitrogen into the beer can alter the flavor profile slightly, which might not be preferred by all consumers who might favor the traditional carbonation methods.
  • The cost of producing cans with widgets may be higher than standard cans, which could lead to a hig ...
