Many thanks for this very useful timing!

One thing I would say on the Aeropress regards your comment about leakage around the edges. If you will measure the diameter of the paper filters dry and when fully wetted, you will find that, like most things, they expand after the fibers imbibe water. Therefore, I recommend that the filter be thoroughly wet before it is placed in the end-cap holder and smoothed out so that it optimally covers the available area. Then after that is achieved, it the end-cap should be screwed into the cylinder. This will ensure that the perimeter of the cylinder wall optimally contacts the paper filter and forms a compressive seal. The way you did it in the video, clamping the dry filter into the cylinder and then wetting it, will result in less than optimal sealing at the edges and wrinkles in the surface of the filter following wetting as you did it after clamping. Another amazingly informative video. Thanks

I find myself constantly fascinated by the things people are using periscope for. What a great use of this new app. Very inspiring.

[@HeliOyd]

Your videos just keeps giving. Every time i notice a new detail i did not understand the importance of the last time i watched. Thank you

[@junisarvicini4108]

"ask Matt Perger, that's better.. " I lol. Huge thanks for the video TIm!

[@eb5698]

Great video, tons of information. Thank you for sharing your wisdom with the public Tim, you're a good man.

[@williamlarzelere7196]

Thanks for this great video, I would like to add a couple of comments. AeroPress does not have gap (area where coffee is not being filtered if filter is inserted correctly and tightened down appropriately) hold up to light to confirm. Also, Porlex manual burr grinder does give very consistent grind, check to confirm by spreading grounds on sheet of paper and comparing with other grinders.

[@michella1913]

The AeroPress definitely lets pass tiny particles into the yielded beverage. If you have a glass cup, just look at the bottom under a light passing through, and you will observe how many of these particles end up in the cup. It's quite obvious. If you don't have a see-through cup, look at the bottom of your cup when there's only little beverage left in the cup. You'll also see them.

Nacimiento is one of my favorite coffees. Tastes like a chocolate covered cherry. TW roasts very light as with most European roasters. The coffee almost tastes like tea. All of his testing definitely seems to have paid off as that is as close to perfect coffee as I've come. One of the top roasters in the world.

[@VibiemmeDD]

Thanks Tim! I alleviate the 'mountain' by using the the supplied Aeropress paddle in a sweeping motion rather than a stir. I prefer the Able disk after trying several brands, and while I have the new Able 'fine' disk, it's harder to keep clean than the coarser one... both get cleaned with a common nail brush. Cheers!

[@thijsbaarda]

ok, you've convinced me, I'm (finally) gonna get a refractometer for myself. Also thanks again for sharing your knowledge.

[@axlpam]

fantastic videos! thank you! Maybe you could turn the camera in the next one 90° to have a bigger picture!

[@andreasb.769]

What I think is worth baring in mind is the fact that higher levels of heat affect the tannins in coffee.

[@chrisbalocca]

Very informative, thanks.

[@klaskristian1]

Nice video!

[@larkinj27]

This is a very interesting video, thanks Tim for taking the time to do that. It's a very good grounding in brewing coffee, I just wish you could recommend a cheaper piece of kit than the refractometer ;-).

[@bohdaaanek]

+Joseph Larkin digits from refracotmeter are great! but you still have toungue to say wether the coffee is good or not :) so i'd recommend tasting :)

[@andreasb.769]

For a cheaper alternative: you can use a BRIX meter and then apply a formula for calculation in order to convert the data to (albeit perhaps less accurate) information on extraction levels. You might get what you pay for, but it is a cheaper start and can be fun. You can get them on Ebay for about 25-30GBP incl. shipping.

[@thepiecesfit5049]

Thank you Tim for the detailed discussion and tips. Can I ask why the high doses for your brewing methods? Is there any benefit to a higher dose versus a similar TDS at a lower dose and finer grind? 5 grams of extra coffee quickly adds up and can get expensive or wasteful. The SCAA recommends 55 g/L ± 10% which at the higher end of the spectrum equals to 60.5 grams.

[@TimWendelboeCoffee]

i just prefer a stronger cup than what you get with lower dose

[@klaskristian1]

I have a question in terms of cupping, especially with finer grounds! Doesnt the coffee get heavily over-extracted if you let the grounds sit in the cup with water for 10 minutes? When brewing are consearned we learn that for a certain ground so and so many minutes are important to avoid over extractions, especially when fines are involved!

[@Ronnicus]

Hey I actually had a similar question before, I don't know if you found out the answer yet, but my understanding is that grounds stop extracting after a certain point.

[@TimWendelboeCoffee]

You can extract about 30 % of a coffee bean but with most brewing methods / grinders we have today we prefer a range between 18-22% sometimes more. But it is very difficult to reach high extractions with a normal brewing device

[@andreasb.769]

As time passes and the water temperature decreases, so does the rate of extraction in proportion.

[@erxu]

Very good instructions... Now, what about "CinemaScope" instead of periscope...? the constrained video angle get tiresome after a few minutes... Come on ...do it for the viewers!!!
