Learn how to maximize the insulation of your BrüMate Rise 25oz tumbler. Tips for keeping drinks hot or cold from morning to night.
Quick answer
Preheat or prechill your BrüMate Rise 25oz tumbler, fill it to the brim with your drink, and seal it with the leakproof lid to keep your beverage at the right temperature for hours.
Why preheating or prechilling matters
Double-wall vacuum insulation works by slowing heat transfer between the drink and the outside air. If you pour a hot drink into a room-temperature tumbler, the stainless steel absorbs some heat before it can start insulating. The same happens with cold drinks. A quick temperature prep removes that initial energy loss, giving you more sustained temperature retention.
When temperature prepping isn't enough
Even with preheating or prechilling, the biggest temperature loss happens when you open the lid. The leakproof lid on the Rise 25oz is designed to prevent spills, but every time you sip or pour, warm or cool air enters. For maximum duration, keep the lid closed as much as possible and avoid leaving the tumbler in direct sunlight or a hot car.
Steps to keep drinks hot or cold all day
- Preheat or prechill the tumbler: Fill the Rise 25oz with hot water for hot drinks or ice water for cold drinks. Let it sit for 2-3 minutes, then empty it. This warms or cools the stainless steel so your drink doesn't lose its temperature immediately. A common mistake is skipping this step — your drink will cool or warm faster if the tumbler starts at room temperature.
- Fill to the brim with your drink: Pour your hot coffee, tea, or cold water right to the top. Less air inside means less temperature exchange. Leave as little headspace as possible. If you only fill halfway, the air above the drink will absorb or release heat, reducing insulation efficiency.
- Seal the leakproof lid immediately: Screw on the Rise lid tightly after filling. The lid's seal prevents heat or cold from escaping through the top. Avoid opening it unnecessarily. Every time you open the lid, you let in ambient air — plan your sips to keep the lid closed as much as possible.
- Store in a stable environment: Keep the tumbler out of direct sunlight or extreme cold. A shaded spot at room temperature helps maintain the drink's temperature for hours longer than a hot car or freezer. Even the best insulation can't fight a 100°F car interior — use common sense about where you leave your tumbler.
