anyone here got their hands on the DF64 or G-IOTA grinder already?
Looking for a flat burr grinder to partner with soon to be coming in Bianca...

have you seen anything about this from weber eg-1, lagom p64? the Monolith max is also tilted right? too bad these grinders are really out of reach for common man... our weak ringgit doesn't help...

for home use, i think the grinder will kong first before the burr wears out... anyway, burr wearing out is part of wear and tear.... more important is grind quality, consistency, build quality and reliability.
I believe SSP burrs are uni directional as they have a top and bottom indicator. not too sure about the italmill steel burrs though.

Coming from a kitchen appliance grinder (Breville) going into flat burr i think would be a nice big jump...

It was quite seamless. Ordered it directly from Mr Kuanho Li in Taiwan. just send him an email @ kuanho.li@gmail.com and he'll reply you with the roaster costing and options list.

Gone my base set with extras such as the IR burner, exhaust hood, exhaust fan, sieve tray, 3 digital probes and the Center 304 device for the probes.. Total bill came up to around 1800 usd with shipping... shipping is damm ex as he uses DHL.. cost about 150 usd on shipping... On the upside, shipping is very fast and efficient. No issues with kastam. I got my roaster 10 days after making payment via paypal.

one thing to note if anyone wants to get the roaster with the IR burner... The max capacity of the stove is about 6kpa (based on Kuanho's specification).. our normal home gas regulator only runs up to 2.5 kpa which is insufficient to supply the necessary gas pressure. We had issues on thermal side which limited us to max 300g batch only in the beginning as there's just not enough heat to roast higher load.

I got fed up and against advice, i switched to the high pressure gas regulator (which they use for tai chow style stove burner). it goes to 2bar pressure (which is 200kpa)... The trick is to slowly turn the gas knob on the cylinder side and use the gauge to regulate the gas pressure... have to be careful because if too much it'll basically blow the gas regulator (it runs to max 10kpa). It's abit of a hassle but a necessary workaround as i couldn't find a gas regulator that runs at the recommended pressure. With the high pressure reg, we can hit 6kpa on max output.

The roaster is rated to 700g but we only roast up to 500g maximum. above that, the results are not consistent. You'll also need to get a Variable AC controller to regulate the fan speed. kinda hard to do with just the damper.. I'd also recommend to get a full solid drum instead of the perforated drum as it's really messy with chaff dropping all over the place while roasting.

I find the roaster good for someone who's trying out roasting and want to learn the mechanics of it without costing too much or being too complicated. It is very well built and beautiful. However it also has it quirks which we've learn to work around it such as beans getting jammed in the loading chute due to chaff blocking the pathway... have to clear the exhaust pipe after 2-3 batch if doing continuous roast.

I'm planning to go for a bigger 2.5kg roaster once we work out the kinks and get the production running smoothly.

get the burner from Huky as the size it's just ngam ngam fit the roaster. Also because he has modded it with additional needle valve with pressure gauge so u can have a finer heat control on the burner.

Probably down the road 2-3 months time will look into bigger roaster if business maintains the same response. it's a big pain to roast in 500g batch...

AFAIK, bianca needs to pre-order due to hot demand.. so far haven't seen anyone sell ready stock here. even 2nd hand snapped up super fast.. I'm one of the ones waiting for march stock to arrive.. ordered in January..

Your other alternative is for fast availability for dual boiler machine is the Breville DB. Other alternative is the Profitec Pro 600 (lamarsacoffee), Crem One (from dankoff)

Hi guys,

just to put it out there, we've roasted and sold our blend of beans. Can try us out if you want freshly roasted beans at reasonable prices. We're currently putting our stocks on Shopee where you also get free delivery for beans. Do check us out at Putra Roasters . Our shopee link is Putra Roasters Shopee.

Currently have 5% discount for new followers.

It's been quite a journey of constant discovery applying roasting theory to practice and also sourcing for the best materials / ingredients. Still learning and would like to be able to upgrade to a bigger 2.5kg machine soon. Our buyers have appreciated the transparency on roast date as we update on socmed whenever we do a new batch.

Just an update on the DF64/ DS64 / G-IOTA grinder. Received notice that my unit should arrive next week.. Hope to pick it up and play with it soon. Can do side by side testing with Breville SGP... gonna tarik some guinea pigs for blind test.

We just roasted a new batch for Putra Blend. Letting it de-gas a couple days first before releasing to market (Wednesday will restock)
In the mean time, u can try our Putri Blend which is still in stock.

Paid 1400 for it with italmill steel burr. Ordered mid Feb. Doubt its air shipping.

have you received your grinder?

been using the DF64 (aka G-iota, Solo, Turin) grinder for 3 weeks now.. Ran through almost 3kg of failed roast beans to season the burrs.

Am pleased to report it is a pretty solid single dose grinder for the price.. Mine came spec with Italmil steel burrs and my espresso grind setting is around -3 to -5 past the 0 mark. My zero point is about -10 (kinda hard to see because there's no mark). According to another forumer who swapped to SSP grind setting becomes more manageable due to SSP burrs' thickness. Burr touching point is on a higher ring number (10-15).

Grind rentention / grind exchange is very consistent... weigh in 20g, output is between 19.9g - 20.1g consistently with the use of the blower. I found that sometimes a rogue bean or two will bounce around on the burrs instead of getting ground up with the rest. Have to keep pressing the blower couple of times to get it ground up.. Do other users experience the same?

I Did blind taste of the DF64 and Breville Smart Grinder Pro with a couple friends (properly dialed in shots) and all agreed that the flat burr produces a shot with more clarity and easily distinguishable flavors compared to the muddled SGP shots. Waiting for SSP unimodal burrs to be restock at Lamarsa coffee and gonna swap it out.

For the price sold by J Cofffee, it is a very capable grinder for home use. Solid build quality and easy to maintain. Just some minor niggles and kinks which can be worked around.

Just abit of a plug... you can try out our beans which are quite freshly roasted. Check it out here - https://shopee.com.my/putra.roasters

For espresso based with milk drink, i'd recommend to get Putra Blend which is our signature original blend that kick started our coffee roasting venture. It is a blend of Java & Brazilian bean roasted to Full City (medium dark).
Flavour Profile: Cherries, Dark Chocolate, Nuts with hint of sweetness. Best brew temp around 92-95C.

Our Rajah blend is more suitable for black coffee such as pour over & siphon. its a trio blend of Sumatra, Brazilian & Columbian roasted to City roast (medium). You'll taste more citrus fruits flavours & brighter nuances.

i normally use fresh milk (farm fresh, farmhouse, purefarm, or goodday) whichever that is on offer & available at my grocery store. I've tried with UHT milk (full cream, low fat) and they generally i hate those milk.. Will only use UHT in a pinch where fresh milk is out of stock. They have a tinge of strange aftertaste which spoils the mouthfeel.

For steaming / foaming & latte art, fresh milk is the way to go unless you're lactose intolerant.

actually.. the grinder is quite affordable for a 64mm flat burr single dose.. Got it for RM 1499 with Italmil steel burrs from J Coffee.. needs to pre-order due to the high demand worldwide.
Built quality exceeded my expectation and grind results are quite good. I have a few types of beans which is switch between and not having to run beans through to purge is quite useful.

You can try our beans out... We are micro roaster called Putra Roasters. Currently have 2 types of medium roast blends. Today is last day promo on Shopee. RM 10 off for 2 packs order.

https://bio.site/putraroasters

Putra is suitable for milk based espresso drinks & French press.
Rajah is good for straight black & V60 pour overs.

i personally prefer the standalone v60 drip and decanter.. if anything breaks, i just need to replace that part.. plus putting a nice decanter on the table looks better for serving. Have been using the timemore glass v60 with the provided paper filter. so far have been adjusting brew time by manipulating the grind size. However, i find that if i grind too fine to slow down the brew (target brew is 300ml @ 3:30 min), i'll get lots of stuck grinds on the side of the filter when brewing.

Have to buy more filter papers soon and i'm seeing alot of Hario bleached paper on shopee.. noticed that there's two type of packing, one in plastic wrap, the other is in paper box format. Is there any difference in the two papers? someone i know mentioned that the box paper flows slower compared to the plastic packing filter.

My brewer is the 1-2 cup size.
