Its double-wall construction insulates the contents while keeping the exterior cool to the touch, and graduated markings in both ounces and milliliters let baristas measure precisely without reaching for a separate tool.\u003c\/p\u003e\n\n\u003ch2\u003eInsulation Where It Counts\u003c\/h2\u003e\n\u003cp\u003eThe double-wall glass construction creates a layer of air between the inner and outer walls, slowing heat transfer in both directions. Hot espresso shots stay at serving temperature longer, and your hand stays comfortable during the pour. For a barista pulling back-to-back shots during a rush, that combination of thermal stability and safe handling removes a small but real friction point from the workflow.\u003c\/p\u003e\n\n\u003ch2\u003eBuilt-In Measurement Markings\u003c\/h2\u003e\n\u003cp\u003eGraduated markings in ounces and milliliters are etched directly into the glass, giving a clear read on volume without a separate measuring cup. Whether you are dialing in a new espresso recipe, checking yield against dose, or portioning a liquid ingredient for a specialty drink, the scale is always in hand. Dual-unit markings mean the same glass works across recipes written in either system.\u003c\/p\u003e\n\n\u003ch2\u003eDurable Enough for Daily Professional Use\u003c\/h2\u003e\n\u003cp\u003eThe glass is described by Rattleware as lightweight yet sturdy, and is intended for frequent use in professional settings. A tool that lives on the espresso bar gets handled dozens of times a day; a glass that balances low weight with durability reduces fatigue and replacement cost over time.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDouble-wall insulation:\u003c\/strong\u003e keeps contents at temperature and the exterior cool to hold\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGraduated markings:\u003c\/strong\u003e measurements in both ounces and milliliters for precise pours\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e3 oz capacity:\u003c\/strong\u003e sized for espresso shots and small liquid measurements\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLightweight glass construction:\u003c\/strong\u003e designed for frequent use in professional environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n      \u003cth\u003eDetail\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCapacity\u003c\/td\u003e\n      \u003ctd\u003e3 oz\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMaterial\u003c\/td\u003e\n      \u003ctd\u003eGlass (double-wall)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMeasurement markings\u003c\/td\u003e\n      \u003ctd\u003eOunces and milliliters\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003ePackaged dimensions\u003c\/td\u003e\n      \u003ctd\u003e4 x 4 x 3 in\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWho This Is For and Isn't\u003c\/h2\u003e\n\u003cp class=\"product-fit-yes\"\u003eThis glass suits baristas and home espresso enthusiasts who want a dedicated shot or measuring glass with built-in volume markings and comfortable double-wall handling. It fits naturally into any espresso bar setup where precision and ease of use during repeated service matter.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eAt 3 oz, this glass is not suited to measuring larger liquid volumes or serving full-size beverages. It is a single-unit glass, not a set; buyers needing multiple glasses should order accordingly.\u003c\/p\u003e\n\n\u003ch2\u003eCommon Questions\u003c\/h2\u003e\n\u003ch3 class=\"product-faq-q\"\u003eWhat is the capacity of this glass?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Rattleware Double-Wall Graduated Glass holds 3 oz, making it sized for single or double espresso shots and small liquid measurements. The graduated markings in ounces and milliliters are visible on the glass itself, so no separate measuring tool is needed for volumes within that range.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eDoes the double-wall design actually keep the glass cool to hold?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eYes. The double-wall construction places a layer of air between the inner and outer glass walls, which slows heat transfer to the exterior. This means the outside of the glass stays noticeably cooler than the contents, reducing discomfort when handling a freshly pulled espresso shot.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eAre the measurement markings in metric, imperial, or both?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Rattleware 3 oz Graduated Glass carries markings in both ounces and milliliters, so it works with espresso recipes written in either unit system without any conversion.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eIs this glass intended for home use, professional use, or both?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eRattleware describes this glass as ideal for frequent use in professional settings, though its compact size and precision markings make it equally useful for home espresso setups. The double-wall design and durable glass construction are practical in any environment where the glass will be used repeatedly.\u003c\/p\u003e","brand":"Rattleware","offers":[{"title":"Default Title","offer_id":68203156799709,"sku":"RW-5004981","price":12.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0614\/3315\/1709\/files\/doublewall-2.png?v=1792114840","url":"https:\/\/coffeeroastco.com\/zh-hant\/products\/rattleware-3oz-double-wall-graduated-glass","provider":"CoffeeRoast Co.","version":"1.0","type":"link"}
