Testing: Milk Weight Before and After Frothing

Silly Kat.... Lol

i love my capresso froth pro! and what do is just make my coffee in it...ill add some syrup and two teaspoons of instant! :D and at like 60 bucks its a steal! :D!

Gale and Kat, You ladies are awesome! :D

[SeattleCoffeeGear]

@MrDameattree Thank you! Great tip :) - Kat

[romancewriter]

Are there any videos featuring frothing solutions for lactose free milk? Soy milk doesn't froth the best but since I can't drink reg milk I was looking other solutions.

[SeattleCoffeeGear]

@romancewriter Yes -- if you search our channel's videos, we did tests of Soy, Hemp and Rice milks by Pacific Natural Foods (and we now carry the Soy Blenders series). - Kat

[xandrios]

Adding the least amount of water is not necessarily the best, is it? I assume for example that the one with the least amount of added water is also the one least hot?

[SeattleCoffeeGear]

@xandrios No, they were all steamed to the same temperature. The drier the steam, the easier it is to work with and get microfoam. Wetter steam takes a bit more skill to get good results. - Kat

If you make a latte on the silvia, you will have an americano latte with all the water added!!

[SeattleCoffeeGear]

@Warrenff5 Hahahaha -- well, kind of, I guess ;) - Kat

[jamescitrome]

I use silvia and have very dry steam. You must figure out how to use the machine, which does have a steep learning curve. The key to frothing with the silvia is to not let the temperature light go out during the duration of the frothing. In the steam setting, I will wait for the light to go out, open the steaming valve to let out some water (less water in boiler = more room for steam), wait for the temp light to turn on again, open valve until steam is dry and start frothing with light on.

[SeattleCoffeeGear]

@jamescitrome We're pretty clear on how to steam with this machine, Gail has been doing so for several years. Regardless of the method, it has a much smaller boiler and, therefore, wetter steam, period. - Kat

[jamescitrome]

@SeattleCoffeeGear

My mistake. Comment was in reply to Warrenff5. Quite a few people do not know the proper technique for steaming with Silvia and experience far worse results then demonstrated with your test. Hence the above run down on technique which I find gets the best results.

I just did the your test - 32g - almost 1.5oz of water added.

[snedie69er]

What's the best milk type for (Cough attempting) Latte Art?

[SeattleCoffeeGear]

@snedie69er We have got best results with 2% - Kat

[Evaldas521]

Air weighs 29 g per 22,4 liters.

[SeattleCoffeeGear]

@Evaldas521 Thanks! :) - Kat

[rudiwells]

since everyone else is being super picky on this, the 200 on the scale isn't ML, if it were water yes, but milk contains fats and solids so just cause the scale says 200g it wouldn't be 200ml of milk.

anyway, I just felt left out with all the pickyness going on :o) , either way, thanks a million for posting this, this is also why I like to use my aeroccino I just love my fatty fatty creamy milk froth

we all appreciate the time you guys put into these

[SeattleCoffeeGear]

@rudiwells Thanks! We did measure these as ml, not grams. - Kat

[MrEjachok]

248 with silvia :(

now i need a cappuccinator

[SeattleCoffeeGear]

@MrEjachok Ha -- well, you can still get good quality milk with it, though! - Kat

[aunsell]

:( NO IZZO Duetto II,!

You don't do enough reviews and tests with that mashine. Its such a great mashine, and i'm sure ill get yelled at, but in many ways better than the Rocket mashines.

Please Please Include more :)

[SeattleCoffeeGear]

@aunsell We don't have one here for demo, we just have the Alex II. We may bring in another one as we have had some requests for demo and reviews, etc. I don't think either machine is better than the other; they have different functions, different purposes and a different market. It's more about choosing the right tool for the job than choosing favorites, in my opinion. - Kat

[jochemvanl]

And last: I know you don't want to get to scientific, but getting the variation on these calculations will help to explain a lot of what we've seen. When I look at the numbers (I haven't done any calculations), it looks like the variations is really small - this might mean that the differences are not really important.

[SeattleCoffeeGear]

@jochemvanl Yeah, we were most surprised by the Venezia as we had always assumed it had wetter steam and would, therefore, result in heavier milk post-steam. I don't think it makes much of a difference and, with practice, you can get great frothed milk from all of these machines. - Kat

[jochemvanl]

As always, I love the video's :). Just a small clarification: air does weigh something, although it's not much. Not enough to have any effect on the used scale.

I've also noticed the comments on the frothers that only use hot air, that they probably didn't change in volume / weight. I think they did, because liquids like milk tend to evaporate.

[SeattleCoffeeGear]

@jochemvanl Interesting! There was such a minor change but that would account for it. - Kat

[TheTraumaFactor]

I would have assumed that little, to NO original liquid volume is lost during the frothing process... but then again, you ladies have suprised me before ;)

[SeattleCoffeeGear]

@TheTraumaFactor Nothing was lost, only gained! ;) - Kat

[spyrmak]

in the video you say that air weighs nothing . air has weigth ! if you take a football and weight it and then inflate it and weigh it again it's heavier isn't it ?

[SeattleCoffeeGear]

@spyrmak No idea! I know that steam does and maybe air does under compression? We are not scientists ;) - Kat

[spyrmak]

like mythbusters but with coffee  !

[SeattleCoffeeGear]

@spyrmak coffee busters!

[sergiusz1000]

did you do it with a timer ?

[SeattleCoffeeGear]

@sergiusz1000 No; we decided to steam each to the same place we would steam the milk normally and weigh them there, not using a specific time frame, because that is what people will experience. - Kat

[00wicket]

I don't get it :-(

[SeattleCoffeeGear]

@00wicket What don't you get? Let me know and I'll try to clarify if I can :) - Kat

[youngbarista]

Thanks for the really interesting video. I understand your point, but surely the amount of steam (air) you inject whilst steaming (how much you foam it) will have a direct relationship with the amount of water added. How can you be sure that you are steaming using identical technique each time?

[hivliner]

@youngbarista cause they are goooood,,:-D

[SeattleCoffeeGear]

@youngbarista Gail used her same technique and also the machines perform differently. That was part of the question we received and how we devised the test. They are obviously going to inject different amounts of water/steam for as long as that specific machine takes to get the milk to the same place. That was the test. - Kat

[youngbarista]

@SeattleCoffeeGear ah, that's fine. Interesting test regardless!
