Why I Stopped Rinsing Coffee Filters Before Use?

[@Linkonstigt]

Another point to consider is if you dont pre-wet the filter, there will be less amount of total brew water as some of the hot water will be absorbed by the dry filter. I think its important to at least saturate the filter first. I don't know if it makes a lot of difference, but i think filter saturation is the most important aspect of pre-wetting.

[@MrTsaoo]

That's an interesting thought! I believe the amount absorbed would typically range from 3-5 ml at most, so it might not make a huge difference overall. Still, I appreciate your perspective on this!

[@WaveOfEmocean]

@@MrTsaooMy filters absorb about 6 grams of water. I just happened to notice this morning so I figured I’d come in, haha.

[@libartstech]

I stopped rinsing, but I also only use a Clever Dripper with Cafec Abaca filters. If I were doing pourover still, I'd probably just rinse to help it adhere to the dripper.

[@MrDDiRusso]

I use a reusable metal filter. Paper filters absorb the natural oils in the coffee and give a perfectly clear cup. I prefer the thicker mouth feel that the retained oils give to the coffee. The metal filter will let some grinds through depending on how fine the coffee is ground.

[@MrTsaoo]

Thanks for sharing your thoughts. Yeah, metal filters can be a bit tricky to clean sometimes. I totally get what you mean about preferring that thicker mouthfeel from the oils in the coffee. But yeah, you do have to watch out for those grounds sneaking through. It's all about finding that balance between flavor and cleanup hassle.

Just run v60 and cup under hot sink water before brewing it’s much easier than a pot of hot water. Love the video this was super fun and informative!

[@MrTsaoo]

Cool! That’s definitely much easier!

[@ninjathedog]

Thank you. The A/B test we all really needed. I stopped pre-wetting my filters a while back as I felt it wasted the water. Folding the paper to fit the the dripper helps make sure it sits in (credit VVCAfe). I avoided ceramic and glass as I was concerned it drew away thermal mass from the coffee. These days I bloom with a slow pour in the center to ensure the grinds get most of the thermal energy before the heat reaches the dripper. Seems to work well. Cheers

[@MrTsaoo]

Sounds good! Cheers to great coffee!

[@inhoshin3333]

This video is great! I always use Hario V60, and I'll gonna stop to rinse bleached paper☕️

[@thebarak]

Totally agree. I use bleached Kalita filters, and they don't change the taste of the water one little bit. I never rinse them anymore. I don't preheat either, but I live in a tropical climate. Perhaps I would preheat if I lived in a temperate zone.

[@MrTsaoo]

True! Agree on the temperature difference.

[@Thehotdogman1221]

Hey! Loved the video! I've always heard preheating can impact your brew severely, though it might change from coffee to coffee. Don't you think you should've tried tasting the preheated comparison cups after they've cooled down a bit so that the details are clearer? Maybe you did offcamera? That's the only thing that made me wonder about your process! Lovely topic!

[@MrTsaoo]

In my opinion, they are really close even if I wait for the temperature to get lower.

[@CaveyMoth]

I usually put a chopstick into the V60 to hold the filter in place before pre-rinsing with room temperature water.

[@MrTsaoo]

That's a cool way to hold the filter! Thanks for sharing!

[@gunting]

For me I notice zero taste difference. However, I rinse so that it latches nicely on my V60 dripper, it irks me a bit when it's off centered or leaving weird "air bumps" on certain places. I don't do it on flat dripper though, they sit nicely by default.

[@MrTsaoo]

Totally agree! But I found out that if I fold the paper in a right way could always fit with the dripper perfectly.

[@smokywaterstudio]

Needing to rinse before use just feels like a slow (dripp) waste of water which is already in limited supply. Especially when you consider billions of cups are made everyday around the world.

[@MrTsaoo]

Wow! That’s a great point there, didn’t think about that!

[@collin4194]

Compared to the 100+ litres it takes to produce the beans per cup of coffee, i dont think 100ml of rinse water is the real problem here.

[@nyanuwu4209]

It's only a waste of water if you yourself waste the water. I rinse filters - sometimes, if they need it - to help them stick to the brewer or maybe I'm just preheating my device (a glass Switch needs it) and the filter's already in, but that rinse water goes right back in the kettle to reheat.

[@7531monkey]

Ill use all the water I possibly can.

[@Lovepreet_Singh93]

I use the rinse water to wash my cup. I don’t just throw the rinse water in the sink.

[@oVoBarista]

I think driper must hot before use! Should i alway make it hot.

[@gusatvoschiavon]

i just rinse the paper to heat up and "clean" the karaf. like i always put the v60 with filter on top of it when i put the water to boil and start to grind the coffee

[@OrcadianOtter]

Thanks for doing the experiment for us 🙏

[@MrTsaoo]

You’re welcome😁

[@bjornlothbrok2089]

Which V60 are you using in these tests? Is it the ceramic or white plastic version?

[@MrTsaoo]

Ceramic!

very informative. that's all i can say.

Thanks bro!

Thank you for your videos with experiments and every detail ! My friend laughs and call me a perfectionist ,so welcome to your club! ;-)

[@MrTsaoo]

Great to have you in! That is what my friends did as well. lol

[@scottm2553]

I've never heard anyone talking about this, but a chemical called epichlorohydrin is used in coffee filters and tea bags regardless of whether or not it's bleached to bind the cellulose fibers so it doesn't fall apart when exposed to water. I wonder if this also contributes to the paper taste. It's also carcinogenic. The more you know 🌈✨

[@MrTsaoo]

I never heard about that, after I do some research, I do not think that epichlorohydrin is in those big brand paper filters.

[@scottm2553]

@@MrTsaooThat's good. I don't know all that much about it but ditched filter paper as a precaution

[@nyanuwu4209]

@@scottm2553 A precaution against what? You and everybody eats and drinks countless potentially-carcinogenic things every day.

[@christychenchen5437]

That is new for me

[@nyanuwu4209]

I've never had paper flavor from a filter. I get paper flavor from chaff (the appropriately papery coffee bean skin), and there's maybe 0.2% of content even bringing up chaff removal.

[@MrTsaoo]

That is a good point! I think the coffee bean I regularly use already had the chaff (silver skin) mostly removed. But yeah, it easily happens when you're using light roast coffee.

[@coffeesali]

Good sharing ❤

[@MrTsaoo]

thank you

[@LindenRanch]

Now I will be buying bleached filters. I preheat so that coffee stays hot longer.

[@nyanuwu4209]

You found your conclusion at 3:40 - no difference unless the filter's unbleached - so why is this padded out to 10:21?

[@MrTsaoo]

Just want to remind you to buy some decent paper filters. I can't promise that people won't taste paper if they use some no-name bleached filters.

[@troystallard6895]

I bought Keurig's bottom of the line coffee maker last year, along with four stainless steel reusable pods. I roast a week's worth of coffee each Saturday in a little Korean ceramic roaster over a Coleman stove on my porch, and spend five minutes with a hand grinder each morning while I'm catching up on the headlines. Seriously happy to be done messing around with paper filters, making a pot each morning and throwing most of it out, spending 20 minutes heating water and doing a ritual pour, or any of that other stuff. And I drink excellent fresh coffee....

[@MrTsaoo]

It sounds like you've found a coffee routine that perfectly suits your preferences and lifestyle. Good for you bro!

[@nyanuwu4209]

"making a pot each morning and throwing most of it out" "spending 20 minutes heating water" Why were you even doing those things? I've never done either of those things making coffee. That just sounds like you were making weird choices.

[@troystallard6895]

@@nyanuwu4209 I've never made a twenty minute ritual out of heating water and doing a slow coffee pour,, but I've known people who do. And if you don't think a lot of people have made a pot of coffee, had a cup or two and thrown the rest out the next morning, you simply haven't been paying attention. Speaking of weird choices, this is what you decided to get your panties in a bunch about? Really?

Never heard of rinsing a coffee filter in my life, haha. Where are people taught that?

Really!? I heard that all the time. lol

[@skorpers]

@@MrTsaoo Haha, yeah actually, I grew up with steel mesh containers in coffee perculators as the main type. When I started witnessing coffee makers I never knew any differently than people had just put them in dry. But you know it makes more sense to wet them considering that it makes it easier to fit them to the basket.

[@gunting]

@@skorpers in here most people don't use mesh or anything at all. Hot water is poured over fine coffee grounds directly in the glass, without any filtration. They call it, "Kopi Tubruk"

[@nyanuwu4209]

@@MrTsaoo It's also called Turkish coffee as they do a similar thing, although they often add spices (traditionally cardamom). The fine grounds become a sludge as the coffee continues brewing in the cup. Some even eat the sludge after. I did...Once.
