If you look back in our “archives”, I once wrote a piece on Harens Old Tree Estate Kona Coffee. (please revisit to refresh your memory, as this is a standout, artisan, handcrafted, single estate, old tree coffee from Honaunau on the Big Island, well worth checking out!).
I just received this note from owner Duane Harens, (long time friend & former long time sommelier), which I think you might find interesting. At least, I did.
Just a follow up on my last communication – burr grinders and brewing into a thermos.
I was just on the mainland and brewed / tasted my coffee with two different water sources. Every time I taste my coffee using a different water source other than my own I am always amazed at the difference!! One of the mainland sources was county water and the other was water from a well. I was amazed at how “flat” both were. No brightness like I am used to with my water on the Big Island. I bought “spring water” to brew my coffee (I hate buying water for anything!). It had that brightness needed. Another thing – I had to brew into a glass pot on a burner. I couldn’t believe how fast the burner “burnt” the coffee!!! The really sad thing is that nobody else noticed it!! I’m not saying everybody should go out and buy a new coffee maker. Just go to Ace hardware and buy a Stanley thermos. brew it and pour it into the thermos. Don’t let it set on the burner!!
I don’t know how this will effect all of you – just thought I’d pass it on.
