0:00 aluminium mock Express or St steel Venus which one is better I've been testing the bti aluminium Mo Express against the St steel beti Venus to understand if there was any difference in between the choka Poots to run this test I use the chap smoka poot for both models I want to make in the future another video where I compare the four cups or even the six cups but still with the two cups I got very inter in information the first difference of course is the material the vet Mo Express is made of aluminum and the Venus is made of stainless steel we know that they are two different Metals but one interesting thing and also a very
0:46 important detail in between the two mocha pots is the thickness of the two materials the aluminium mocha Express is thicker than the stest steel Venus this is probably because the aluminium is lighter and also less resistant than steel the material of Venus is thinner probably to make it lighter and also probably to make it cheaper this aspect definitely makes a difference in terms of Brewing but we will see that in a minute another two things that can make a difference in Brewing are the first one is the different diameter of the boiler's bottom compared the cha Poots the second one is the distance of the valve from the bottom of the boiler the aluminium o Express has a diameter
1:32 around 7 cm and the St steel Venus has it around 8 cm meaning that Venus has a wider heating surface and the distance of the valve from the bottom of the boiler in the mooch Express is around 3.4 cm and in the Venus is around 25 cm of course here I'm talking about the two cups Moka poot that means for the same amount of water that I put in the boiler in both mocha pot in Venus the water will sit lower and wider this plus the fact that the material is thinner it will make the water inside the Venus warm up faster compared to the water inside the mocha Express now to
2:20 see the difference in the cup I've been brewing the same coffee at the same grind size placing the same amount of coffee in the basket and the same amount of water in the boiler and Brew both moccas in the same way on the stove during this test I've been brewing different type of beans also different roasting levels with different grind sizes and different coffee to water ratio the one I will show you in this video it was good for this kind of coffee that I used and also was more or less the average I was getting every time I was using a medium to dark roasted beans uh plac in the basket 11 G for reference I grounded coffee with a commandant and grinder at 13 regular Clicks in the boiler 90 G of water at
3:06 room temperature and as I said before I did the same thing for both mocha Poots for metal filtration I use the standard filter that I found in the Box for both B Mo Express and be Venus but I used for both silicon gaskets to make sure that there was no rubber uh to give me any surprises in The Taste also I did use any paper filter on the stove I always place the mochas on the smaller diffuser at low heat the first difference is the Brew time Venus always Brew my coffee faster on average 1 minute faster that means because of the thickness and the shape of the boiler this mocha can build up the pressure that pushes the water up
3:52 in less time compared to the mocha Express the flow during Brewing was steady for both mocha pots but of course faster for Venus the second difference that I found is the coffee beverage yield when I went to weigh the beverages I noticed that Venus always delivers less coffee in the cup compared to the mocha Express for 90 G of water in the boiler this is what I was usually getting from the mooch Express and this is what I was usually getting with Venus that means Venus retains more water in the boiler compared to the mocha Express now taste wise what's the difference first of all I noticed that every coffee that I made with Venus came out with a
4:37 lower temperature compared to the ones I made with mocha Express this is probably because in Venus the water rises faster compared to the mooch Express where the water probably has more time to get hotter tast in the cup is also different the coffee in the aluminum has an high body a good sweet nness but it has this rough sensation in my mouth especially in the aftertaste the coffee from Venus also is sweet and balance the body is thinner but I don't get that rough sensation in my mouth that I get when I drink the coffee from the mooch Express and this overall makes a better aftertaste I actually like the coffee
5:23 quality in the cup that I can achieve with Venus but that is a personal preference also I know no and you can see by yourself that the coffee from mooch Express looks cloudier compared to the one from Venus it seems more coffee particle pass through the filter of the aluminium pot I think this happens because of the higher erosion we have in the mocha Express let me explain quickly there are two different ways of coffee extraction the fusion and erosion diffusion is more of a chemical extraction and is when compounds from from the ground coffee move from an area of ey concentration so the inside of the coffee to an area of low concentration
6:09 and that is the water that happens as soon as the water enters in contact with the coffee that is something you can see especially when you brew with a steep bag like for coffee or even like for tea as soon as you dip the bag in the hot water you can see all the compounds and the color start to mix with the water and that is diffusion erosion instead is more of a physical exraction and is when the water flow physically breaks down and Carri away small particles and compounds from the coffee ground surface this exraction is very common in espresso and also when you agitate coffee and water together like for example in a French press and this SM particles can give that cloudiness
6:56 intensity wise the coffee from the aluminium o Express taste more intense but actually the coffees from Venus have a higher total dissolved solutes meaning that they have a higher concentration in the cup of coffee particles that we extracted from the ground coffee that we plac in the basket and this is because less water passes through the coffee grounds in the pot extraction wise I can achieve a higher extraction with Mo Express because more water passes through the coffee grounds in the pot and also this water is hotter then I also did the test with a lighter roasted coffee and as I suspect the coffee that
7:42 achieved with Venus were all of them a bit under extracted this is because the lower temperature of water and also the reduce amount of water that pass through the pot as explain from this video here light roast needs a higher temperature and more water to achieve that balance in instruction instead the light roast brewed in the mock Express tasted more balanced and sweeter it's finally time to run some conclusions aluminium o Express makes higher exed coffee that they are hotter as a beverage but a bit rougher compared to the St steel Venus based on the Brewing variables that I used I can say that the aluminium
8:27 mokapot gives a better better results with the light roasted coffee on the other side in my opinion Venus provides a better cup with a medium to dark roasted coffee it makes a cleaner cup and also more balance but it doesn't perform as well as the mock Express with a lighter roasted coffee also the coffee beverage from Venus comes out at a lower temperature concluding I will say that I suggest St Ste Venus if you're Brewing uh dark roasted coffee and also if you don't mind to have have a less hot cup of coffee you can probably bre light rosed coffee if you change some variables like I don't know grinding finer and also placing a paper filter uh on top of the metal filter that will
9:13 increase the pressure inside the pot I suggest mooch Express for a light to medium roasted coffee yes but also if you change some variables you can also achieve a more balanced cup of coffee not over extracted with that roast and this by changing some of the variables for example placing less water in the boiler that will decrease his traction or grind slightly coarser also if you place a paper filter on the metal filter you can achieve a cleaner cup but on standard variables I suggest Venus for a medium to dark roast coffee and mpress with a light to medium roasted coffee Regarding cleaning and maintenance I can
9:58 say vus because it's still steel it's easier to maintain than Mo Espress because it's made of aluminium aluminium requires a bit more carefulness because is a delicate metal but no matter which one you get or prefer the important thing is that you clean your MoCA poot after every usage remove gasket and filter wash all the parts and then dry them to avoid oxidation this is mainly important for the aluminium MoCA Poots I hope this comparison has been helpful to you to understand better the difference in between the beti mo Express and the bti Venus now I would like to hear from you which mocha poot do you have or which one are you planning to get let me
10:45 know by leaving a comment in the section below thank you very much for watching I will see you in my next videos and in the meantime I wish you a wonderful day and delicious coffee ciao
