Hi guys,

two questions:

- why is the dose so low? I though the SCAE standard was 55g per 1000ml not 750ml

- why 3-4min? is that for 55g? it's really down to how slow you pour I guess, but there's no way I'm going to get 4min with 12g for a single cup

Great video however a true Chemex proficianita would most likely boil their water in a glass Chemex tea kettle boiler. Allow the water to come to a boil and remove it from the heat. Chemex recommends 200 +/- 5 degrees.

I made all of the coffee in my coffee house, the Daily Grind in Nashville, Indiana -1976 to 1985 (still in business), using theChemex system.

The MSDS for such felt will ever and always only speak to the polyester -- which is inert.

Unfortunately, regardless of the manufacturer, it's nearly impossible to get specific a MSDS for any possible contaminants the material may contain.

There are known lubricants used in the process of making the felt, and the MSDS may be obtained for these.

Alas, I've still not been able to scrape the minimum together for a purchase of a substantial quantity of food grade material. But I've used the McMaster felt, washing it carefully in Seventh Generation Free and Clear or Shaklee Basic H
