Don't waste time on gimmicks. Some travel presses come with extra filters or built-in grinders—skip them. They add bulk and rarely improve the brew. The same goes for fancy "cold brew" settings on your press; that's a different drink, and if you're chasing a hot cup, it's not helping.

Also, don't obsess over water chemistry while you're traveling. If the tap water tastes fine, use it. If it's heavily chlorinated, run it through a filter bottle—but don't lug a whole water treatment kit. That's overkill.

Another thing that won't fix watery coffee: pressing harder. The plunger isn't squeezing flavor out; it's just separating grounds. Pressing slow and steady is fine, but pressing fast or hard doesn't extract more—it just makes a mess.
