Article Feedback: Banish Uneven Extractions with Weiss Distribution Technique

#1: Post by **RapidCoffee** » March 26th, 2006, 3:24 pm

Have you ever been plagued with espresso extraction problems? Perhaps your pours show early blonding and taste bitter. If you've tried a naked portafilter, you may have observed channeling, spritzies, rim shots, and other evidence of uneven extraction. Any of these extraction flaws may cause unbalanced and undesirable flavors in the cup.

These problems often relate to uneven distribution of coffee grounds in the filter basket. Learn a simple new dosing and distribution technique dubbed the WDT that attacks uneven distribution and helps cure many extraction flaws.

Great write-up John. Now that the WDT has been thoroughly integrated into my routine, I find that I can do it very quickly. I updose by gently tapping around the circumference of the PF with my finger after removing the yogurt container and before tamping, and it is really effective. It is so satisfying to taste espresso free from the bitterness of a poor extraction.

By the way, thank you for the acknowledgment - it made me laugh out loud with surprise.

Great article, I started using your method after I saw the collage you posted on the "watch out JonR" thread on coffeegeek and it makes a hugh difference. Probably the tip that has most improved my espresso extractions.

Add me to the WDT convert list. My Mazzer Doser SJ fills the pf favoring the left side. The WDT technique proves to me that I always had poor distribution at the bottom on the pf. I had some success dosing while grinding, but it was not as consistent as the WDT.

I don't like the added minute it takes to build a shot, but the added consistency is worth while.

Thanks for the article,
Rich

This post is just to add the word Weiss to the thread so that future searchers can find it.

I missed the thread on my earlier search.

My initial tests of the WDT are favourable as well. It seems to be an easy way to get more consistent distribution.

I am another convert. I tried this technique at Espresso Fest in Charlotte. Ever since, my shots, kidding, are 90% of time even. and I mean, amazingly and consistently even. Thank you so much!!

What are you doing that adds 1 minute? Other than plopping on my plastic ring (bottom of a tupperware container that fits perfectly in a 58mm PF) and stirring, everything else is as normal. Maybe adds 10 seconds to my routine. How long are your stirring for?
