# AeroPress Flow Control Source: https://dailyextraction.com/methods/aeropress-flow-control/ Last updated: 2026-10-16 > The AeroPress Flow Control filter cap swaps in for the standard cap and has a pressure-actuated valve that stays closed until you press. That stops coffee dripping through while it steeps, so you can brew for longer and use coarser grinds. Launched in April 2023, it fits the standard-size AeroPress models but not the XL, which has its own Variable Flow Control Cap. ## At a glance - Grind: Medium-fine (table salt) - Category: Hybrid & Air-pressure (Hybrid) - Difficulty: Beginner - Origin: United States, 2023 - Also known as: AeroPress Flow Control filter cap, Flow Control cap, AeroPress no-drip cap ## Steps 1. **Swap the cap**: Put a standard-size paper or metal filter in the Flow Control cap and screw it onto the chamber in place of the standard cap. 2. **Stand it on a mug**: Stand the AeroPress upright on a sturdy mug. The valve stays closed, so nothing drips through. 3. **Add the coffee**: Measure the coffee with the scoop that comes with your AeroPress and add it to the chamber. 4. **Add water and stir**: Pour in hot water and stir. Let it steep for as long as your recipe says, without losing coffee into the mug. 5. **Press**: Put the plunger in and press down. The pressure opens the valve and the coffee flows into the mug. 6. **Clean it**: Push out the used coffee and filter, then rinse the cap. AeroPress says it can also go on the top rack of a dishwasher. The **AeroPress Flow Control** filter cap is a replacement cap for the [AeroPress](https://dailyextraction.com/methods/aeropress/) with a **pressure-actuated valve** built in. The valve stays shut until you press, so **no coffee drips through while it steeps**. That lets you steep for longer, use coarser grinds and brew upright instead of turning the AeroPress upside down. AeroPress launched it in **April 2023**. Here's how it works, what it fits and how to use it. ## The short version - **A filter cap with a valve** that opens only when you press. - **Stops drip-through**, so you can steep longer and grind coarser. - **Fits the standard-size AeroPress models**: Original, Go, Clear, Premium and Go Plus. - **Not the XL.** The XL and Clear XL have their own Variable Flow Control Cap XL. - **Takes paper or metal filters**, or both together. ## How does the Flow Control cap work? A standard filter cap is open, so once you add water some coffee starts **dripping through into the mug** before you press. The Flow Control cap has a **pressure-actuated valve** that stays closed while the coffee steeps. It only opens when you press the plunger and build pressure. Everything stays in the chamber until you're ready. ![Diagram comparing the standard AeroPress filter cap, where some coffee drips through while it steeps, with the Flow Control cap, where the valve stays closed until you press](https://dailyextraction.com/diagrams/aeropress-flow-control.svg "With the Flow Control cap, nothing reaches the mug until you press.") ## Which AeroPress does it fit? | AeroPress model | Standard Flow Control cap | | --- | --- | | [Original](https://dailyextraction.com/methods/aeropress/) | Fits | | [Go](https://dailyextraction.com/methods/aeropress-go/) | Fits | | [Clear](https://dailyextraction.com/methods/aeropress-clear/) | Fits | | [Premium](https://dailyextraction.com/methods/aeropress-premium/) | Fits | | [Go Plus](https://dailyextraction.com/methods/aeropress-go-plus/) | Fits | | [XL](https://dailyextraction.com/methods/aeropress-xl/) and [Clear XL](https://dailyextraction.com/methods/aeropress-clear-xl/) | Doesn't fit: use the Variable Flow Control Cap XL | ## What about the XL? The standard cap is too small for the [AeroPress XL](https://dailyextraction.com/methods/aeropress-xl/) and [Clear XL](https://dailyextraction.com/methods/aeropress-clear-xl/). For those, AeroPress sells a separate **Variable Flow Control Cap XL**. Instead of a pressure valve, it uses an **open and close tab**: close it while the coffee steeps, open it when you're ready to press. ## Which filters can you use? It takes **standard-size filters**. You can use a paper filter, a metal filter, or **both together**. AeroPress names its **Stainless Steel Filter** and **Gold Tone Super Fine Filter** as options. ## Is it an alternative to the inverted method? Yes. People turn the AeroPress upside down, the [inverted method](https://dailyextraction.com/methods/aeropress-inverted/), to stop coffee dripping through while it steeps. The Flow Control cap does that with the AeroPress the right way up, and AeroPress suggests it as an alternative to brewing upside down. ## What grind size should I use? Start around **medium-fine**, like any AeroPress. Because nothing drips through, AeroPress says the cap lets you use **coarser grinds** with a longer steep. Grind finer if it's sour and thin, coarser if it's bitter or hard to press. ![Chart of coffee grind sizes from extra fine to extra coarse, with medium-fine highlighted for the AeroPress with a Flow Control cap](https://dailyextraction.com/diagrams/grind-size.svg#medium-fine "Start around medium-fine, then go coarser if you steep for longer.") ## How do you use the Flow Control cap, step by step? 1. **Fit a standard-size filter** in the Flow Control cap and screw it onto the chamber. 2. **Stand the AeroPress upright** on a sturdy mug. 3. **Add the coffee**, measured with your AeroPress scoop. 4. **Pour in hot water and stir.** Let it steep as long as your recipe says. Nothing drips through. 5. **Press.** The pressure opens the valve and the coffee flows into the mug. For recipes, see the main [AeroPress guide](https://dailyextraction.com/methods/aeropress/). ## How do you clean it? Push out the used coffee and filter as usual, then rinse the cap. AeroPress says it can be cleaned with **a quick rinse or on the top rack of a dishwasher**. *General guidance only. Always follow the instructions that come with your AeroPress and Flow Control cap.* ## When did it come out? AeroPress announced the official launch of the **Flow Control Filter Cap** on **6 April 2023**, describing it as a way to stop drip-through, brew for longer and use coarser coffee. ## Should I buy one? - **Get one** if you'd like longer steeps or coarser grinds, or you've been using the inverted method to stop drips. - **Skip it** if you're happy with your usual AeroPress recipe and don't mind a little drip-through. - **For the XL**, look for the **Variable Flow Control Cap XL** instead. More on choosing in the [AeroPress kit guide](https://dailyextraction.com/tools/aeropress-brewer/). ## Flow Control vs other ways to brew - **[Inverted AeroPress](https://dailyextraction.com/methods/aeropress-inverted/):** stops drips by turning the AeroPress upside down, which AeroPress advises against. - **[AeroPress Original](https://dailyextraction.com/methods/aeropress/):** the standard cap, with a little drip-through while it steeps. - **[Iced AeroPress](https://dailyextraction.com/methods/iced-aeropress/):** an AeroPress brewed over ice. Explore every hybrid brewer in the [hybrid chapter](https://dailyextraction.com/methods/hybrid/). ## Words used in this guide - [Steeping](https://dailyextraction.com/glossary/steeping/): Steeping is leaving ground coffee to sit in water so its flavour dissolves out, as in a French press or cold brew. - [Metal filter](https://dailyextraction.com/glossary/metal-filter/): A metal filter is a fine stainless-steel mesh that holds back coffee grounds, as used in a French press plunger and some reusable pour-over filters. ## FAQs ### What does the AeroPress Flow Control filter cap do?
