Siliconslave's how to make espresso thread

Managed to get into the Geisha earlier today - very different in some aspects from the Muscat, but some similarities between the two which might be down to the roast rather than the beans themselves.

As with the Muscat, I wasn't getting any strong aromas from the bag pre-grinding, but there was definitely a floral element there which reminded me of tea. Base notes were dark chocolate and caramel, which I think comes from some of the beans being a lot darker than the others. You can see that from the two beans next to each other in the upper left area - one very dark, one very light.

After grinding the aromas got stronger, would say the most obvious smell was of a strong, stewed tea along with a faint sour note.

Bloom phase was very interesting, with a lot of bubbles coming out of the coffee bed and a lot of activity for the first 10-seconds before it settled down.

Totally forgot to change the grind size from the Muscat and managed to get close to the 3m30s mark, but will go down a touch for the final batch of beans to see if that makes much difference in the cup.

Tasting the Geisha, it was immediately sweet and bright with that floral, almost steeped tea-like flavour I got from the ground beans. I can't quite pin down what the other flavour I'm getting is, but I want to say it reminds me of endive - it's a little bit citrus, a little bit tart with a bitter finish. It's very faint, but present and adding milk to the cup did mellow that out and balance the sweetness with the tartness pretty well.

Very enjoyable to drink, but lacks the refinement I would expect to see from a commercial roast of Geisha. Definitely some bitter notes present and I think it is the variance in colour of the beans.
 
Sounds like I have lots of room to improve, definitely need to improve the consistency across the beans.

Thanks for the feedback! Might have to pick your brain again when I’ve done more roasts down the line :)
 
I roasted the last bit of Geisha, a little but better but still not as even as I would like. I think about 10% are too dark and 10% are too light.

Also did 175g of this to be ready for a couple weeks' time. Very high altitude beans, tiny tiny beans so will take a bit longer to gas off.

This one is much easier to get evenly, perhaps it's the smaller size and easier to move inside this particular roaster vs the larger bean in the Geisha. Overall much more even with the exception of like 1 or 2. I put that single one that isn't roasted in the middle which i threw away after.

Works out to 15.5% dehydration.

Also got one of these 1 way valve tin to store it in. Fits 150g of coffee perfectly.

If anyone here wants to buy a Bigger Coffee tin, There's a Roaster in Scotland that uses Coffee tins instead of bags for their orders. See here.

Not uncommon to have some variance, but I guess this is where roasters might blend a couple of batches of a particular roast to get the flavour(s) they are expecting. Certainly an improvement on the last batch, you are coming along at a rapid pace.

Ooooh, that looks really nice. Very pro with your new tin as well!

Have you tried their coffee? Rate it? Been on my radar for a while, but not got around to buying anything... yet.

Awesome, just ordered a couple of tins.
 
£12.50 for 150g.

My tin cost me £2.50 so £10 for 150g, it cost about £16 for 500g green/ 450g (roasted) for me and mine is like the cheapest Geisha from Green Coffee Collective, there are some like £40 for 500g, so it works out like £5.50 or soin raw ingredients.

They are not making much money with everything else like VAT, energy, time added.

I think i will get one of those in the name of science and compare to mine.

I think the max capacity or the ideal batch is like 150g in this roaster and need to raise the start temp higher. Without any probes inside it's difficult to figure out the temperature inside and the 2 batches i tried with a starting temp of 180c in the machine (who knows what temp it is inside the chamber), came out a little uneven. Starting at 190-200c and lowering the batch size gave more even results.

Pretty good TBH. I bought a Xmas twin pack last year, You chose 2 out of the tins available. I bought the Xmas blend and the Bourbon infused Colombian. About £29 for both, which I thought was a lot for 500g. I've paid that for 1kg. But it was for Xmas and one of the tins comes in handy for Coffee bean storage.

I've just received 2 bags from Square Mile last week, but for £13 to try a new roaster sounds like a good deal to me. Worst case I get a free funky tin for storage.
