I had bought a Gaggia Classic (2012 or 2014 model I think it is), with all the necessary mods already in place (PID, OPV fitted, Rancilio steam wand). For a while I used it regularly but then I put it away and used my bean to cup exclusively. Recently went to my cousin's house who has a Sage Barista Express and he made me coffee (Union Roasted Christmas blend, Baked Apple, Cinnamon, Cocoa notes). It tasted miles better than what the bean to cup produces, not a surprise. What was a complete surprise though was it looked like it would be awful tasting. Shot ran really quickly, water, and he had absolutely no clue about ratios. That gave me an incentive to dig my Gaggia out again. Recently bought the cheap single dose SPTK 38 grinder based on Dave's review of it, to use with the Gaggia. I'm pulling decent ratio (1-2.5), in about 30 seconds. Liquid pours after about 7 seconds. But it tastes meh. I've tried various different adjustments, sometimes I get a nice result, sometimes not. What I have noticed consistently is that the temperature on the PID display drops mid shot. But this drop varies from shot to shot. Sometimes 1-2 degrees, sometimes 3 degrees, sometimes the drop occurs slowly, sometimes quickly. When I bought this Gaggia, it was always only as a stepping stone to a better espresso machine. Recently I've been eyeing up the Lelit Mara X2. Would I get better results with the Lelit?

Not a Gaggia user so others may chip in but I don't think a 2-3c decrease in pid temp is particularly out of the ordinary. I'd also guess it's not what's at fault here but either way more info would be helpful. It would be helpful to hear what about it tastes bad and what type of beans you're using. And what starting temp are your brewing at?

The beans are Union Roasted, Christmas blend, which they state as medium roast - certainly doesn't look dark. I started with 96degC (I saw this drop to 93 at one point) but then adjust it to 95 (with the hope it will settle between 93-94). Initially I was aiming for 1:2 ration in 25-30sec but then I updosed, grind slightly coarser, and increased the dose (that's what one of the espresso help guides I read indicated based on what I was tasting). What I was tasting was no sweetness at all, struggling to taste the notes indicated, and it tasted under extracted (sour). I first tried grinding finer (only a notch to start with) but then that made it taste more bitter, I never got the sweetness. That when I decided to get help from online guides (regarding how to adjust based on what you are tasting). My very first started was 14g in, aiming for 28-30g out, in 30 seconds. What I have no eventually ended up with is 15.5g in, 43g out, 23 seconds and that has been the closest to tasting with some sweetness and closer resemblance to the indicated notes. I'm going to keep the 15.5g in, go half a notch finer for my next one and aim for 45g out, maybe take it to 26ish seconds I think. I'm not sure if that was at all helpful 🙅🏻♂️

@"DrForinor"#p33271 the temp registered on the pid doesn’t always reflect what’s measured at the portafilter for small single boilers. In the manual of my Ito mod there is some scace data on a Rancilio Silvia showing that with no heating during the shot the temperature measured by the pid dropped from 94-88°C, but the scace (I.e. puck temp) rose to 87°C over the first 11s and was then flat for the rest of the shot (if you’re interested then download the “leva! 2.0 for Ito” from http://projectcaffe.bplaced.net/downloads.html, and look in the firmware manual page 57). On the flip side if you can’t disable heating during a shot and the PID is kicking the element on to compensate for the incoming cold water, then you can end up with the water being too hot, especially as the water outlet pipe is usually quite close to the element. The piping also heats up so there is less cooling. The Ito manual stated they measured a 3°C increase in temperature from this effect. In summary, if you can’t disable heating during the shot you could try changing the set point and seeing if that helps. Or perhaps the beans are just meh.

@"DrForinor"#p33276 do the beans have a roast date? If they’re a few months old that won’t help either

The roast date on the bag is 1st Nov 2022

@"DrForinor"#p33280 on the older end then, but not terrible. I usually try to drink all my coffee in the 2 - 6 week post roast window

@"hornbyben"#p33281 What do you do with beans that might be older than 6 weeks? This was the reason for me updosing, and increasing yield (it's what my search revealed for older beans), and it certainly improved it for me.

@"DrForinor"#p33282 accept poorer flavour if I end up in that position, and try to buy fresher or drink quicker next time. If I know I definitely won’t be able to (like decaf that I keep in for guests) then I freeze them. Most decent roasters will send you coffee less than a week from roast (assuming Royal Mail don’t take forever to actually get it to you).

I used to set my PID to 102 degrees to allow for the tail off in temp. You could try that to see if the flavour improves or not.

@"Jollybean"#p33293 Thank you, I'll try that. Given the drawbacks that still exist in a Gaggia with a PID, (and keeping in mind that I always knew the Gaggia would only be a stepping stone), would the Lelit Mara X2 be a worthy upgrade? I don't steam much milk. Usually make my espresso, add water from the kettle as much as I need them add milk straight from the fridge. But I want a machine that will give me consistency without me worrying about it or having to make unnecessary adjustments for the lack of consistency.

Gaggia woes

FadedFrontiers

DrForinor in that case I’d go for a dual boiler (DB) where you can keep the steam boiler turned off when it’s not needed to save energy.

Mara x2 is a heat exchanger (HX), Lelit or Elizabeth is their DB models and if you want minimal fuss and general consistency then the Elizabeth is the one to go for since it doesn’t have flow control or an e61 group which takes longer to heat up and requires more maintenance.

DrForinor

FadedFrontiers

Is the Elizabeth the only other option? I know it’s superficial, but I don’t particularly like it’s aesthetics.

Cuprajake

Acs minima dual boiler around the same price as the Elizabeth iirc

DrForinor

The ACS is a good machine isn’t it?

FadedFrontiers

DrForinor yes it is, I only suggested other Lelits as you mentioned the Mara. A few users on here also have one so will be able to advise but it’s quite the steaming beast, with an e61 group minus the lever so that’s less maintenance than traditional e61s where you’ll need to lubricate the cam after backflushing.

Cuprajake

Yeah,

Big boilers, pid, solenoid group,

DrForinor

Any negatives to the ACS?

DavecUK

DrForinor Performance wise nothing, it plays well against the big boys, maintenance is minimal because of a solenoid group. It has awesome steaming with a big 2.3 litre steam boiler and dual boilers with good PID control for brewing.

The downside might be it’s shipped from Italy and the warranty although for 2 years is parts only, making it necessary to fix it yourself or take it to an espresso tech to fit any parts. The parts are all readily available and mostly easy to fit. However due to the big boilers, access to the pump usually requires removing a boiler, that said the type of compression fittings ACS use make that easy enough.

Many happy owners of Minimas here, perhaps a few will chip in.

DrForinor

FadedFrontiers

You’re talking about the Elizabeth there? Any negatives to this one?

FadedFrontiers

DrForinor no I was talking about the ACS Minima, but with both machines you can change the OPV to decrease brew pressure to 9 bar.

DrForinor

Looking at the dimensions of the Elizabeth, it actually suits me much better than the Mara size wise. Online it says 15 bar pressure, is that correct?

DrForinor

Briefly, how do I choose between the Elizabeth and the Minima? Which questions do I need the answers to, to know which suits me best?

DrForinor

Which one (from the Mara, Elizabeth & Minima) will give me an easier life in terms of consistency (and ease of that consistency), reliability, and maintenance?

Cuprajake

Elizabeth and minima are neck and neck

The minima has bigger boilers

But it’s really down to which you prefer and how quick you want it

Please look into good water.

DrForinor

In terms of speed, I am in no rush.

Water wise, I am in Aberdeen (soft water) and I have a filter connected to my water tap.

DrForinor

The only information I can find in regards to the Lelit Elizabeth (concerning pressure) is that it’s 15 bar, is this correct? If I decide to opt for this, is it wise to get the retailer to adjust this before sending it up (if it’s a complicated process)?

FadedFrontiers

DrForinor it should be straightforward but no harm asking them if you don’t want to do it yourself, but I’d recommend getting to know the machine and what the parts do as you’ll need to carry out some form of maintenance on any machine you get to ensure the longest lifespan:

ECM are meant to be reliable machines but I think that one you mentioned a single boiler (and a pricey one at that) so would avoid. As mentioned DB is the one I’d recommend because you can switch the steam off when you’re not using it and will generally get the best heat stability for pulling shots.

CoyoteOldMan

DrForinor I don’t believe either the Elizabeth or the Minima are set up to brew at 15 bar; I think it’s the pump’s maximum achievable pressure. If you are buying new, I’d ask the retailer to set the machine up at whatever pressure you want, but adjustment is an easy process for both:

Minima:

Elizabeth:

DrForinor

How does the ECM Classika PID Espresso machine fare?

DrForinor

Thank you both for your replies.

I’m still teetering between the Elizabeth and the Mara, and trying to decide which works best for me. I do very much like the idea of the built in pre-infusion capability of the Elizabeth. And while I’m not mad on the looks of the Elizabeth, it would fit my kitchen space better.

Are there any big negatives about the Elizabeth I should be aware of?
