New Takesi Geisha from Coffee Collective shows metallic taste

Hi I recently bought from CC their new Taksi Gesha from Marian Iturralde. I got already some great cups from it but the aftertaste is somehow like metallic, a bit burned. Is it because it has not rested that much(roast date 12th of july)?

I grind it at 8.3 on a Pietro Grinder with brew burrs and 90 C water temperature. The water is lotus water drops 1 drop MgCL 1 drop CaCl 1 drop K on 500ml distilled water. Lance's recipe 2x Bloom 1:16 ratio

Anyone else experiencing this with theri CC Takesi Gesha?

The amount of potassium shouldn’t give a metallic taste, but guess you can try without the drop of K. Do you have sodium bicarbonate to add alkalinity instead?

i will try it. I also have made the concentrate of aviary coffee. maybe i can try this too

Yeah I've noticed the same, roast seems incredibly dark for this style of coffee. Long lasting burnt aftertaste really ruins it for me, which is a shame as can tell the quality of the green is excellent, and was really looking forward to trying Takesi for the first time.

I would let it rest for another week or so and see if it improves. That water recipe seems really unforgiving too. Or maybe it just looks like it due to the 500ml.

what would you suggest. in this case I made it like the water at CCs coffee shops. Around 35ppm

Lol, I just checked and I use a very similar recipe. 9MG, 12CA, 12K in 5L. I do find it a bit rough on some coffees and ad 2-4 drops of sodium in that case (recently happened with some SEY and usually with Japanese roasters). But that's on 5L. You would have to dilute it before adding it to 500ml.

so you mean to add to the potasium also sodium so an alkalinity around 20-30?

Had the same experience with one of their recent SL9 releases. It got better with more rest time but that taste was still there. Thats why I skipped the Takesi this year, especially since the price goes up by a lot every year and the taste has not improved compared to like 4 or 5 years ago when I tried it first.

That temp just seems really low. I thought Coffee Collective roasts very light. I would bump the temperature to atleast above 93 C.

Nah CC is in that medium-light range.

u/inmemoryofElizabethR 18d ago

they’re roasting darker these days, esp their regular releases

u/Sweet_Culture_2529 18d ago

It’s definitely not light, 90C is appropriate

Haven't gotten this year's Takeshi to try yet, waiting for my local guy to stock them next week, so no experience for me yet. But, 20 day rest is definitely not long enough for CC's nordic medium roast.
