Hi, everyone! This is Chris from ABarAbove.com and today we’re going to check back on an infusion we started a couple of weeks ago.
So for those of you that missed the first episode, I’m just going to recap what we’ve done so far. So in this jar we have about 1.75 liters of vodka, the skins of 15 lemons, and essentially, that’s about it. I’ve stirred it every day for the last two weeks, I’ve kept it in a nice dark environment, and you know there’s kind of a lot of hangouts. Today we’re going to strain all this out and we’re also going to talk about some of the theories and the general technique behind infusions.
So now that we’re going to put everything in the glass container, let’s take a look of what’s going to happen to once it gets in there. On the left you have the fruits that you’re going to be utilizing and on the right you have the alcohol in a container. So we’re going to add all these ingredients to get in into the glass container. And now that it’s keeping in the alcohol, all the essence of the fruit is going to escape the fruit and go into the alcohol, so all the oils, all the sugars, and any of the juices that are left over, they’re going to try to make their way into the alcohol. And when that happens, the alcohol is going to rush in and fill up the rest of the fruit with the alcohol. So this process will continue to happen until what you’re left with is Boozy Fruit and Fruity Booze. And like I said, it’s going to go to a point of equilibrium, so that way the fruit that’s left over will have the same alcohol as the alcohol that you want to use, and the alcohol will have the same amount of fruit essence (the oils and the sugars and the juice) as left over fruit as well. So they’ll reach that level of equilibrium.
Now on the previous video on infusions, we mentioned that you should stir your infusion daily and also keep it in a dark place. Now the reason why you’re going to want to stir this is because, if you don’t, one of the things that I noticed in the past is that if I leave the infusion for a few days and come back to stir it, it actually creates a swirl of sugars and juices around it. So what’s happening there is, around the perimeter of this lemon zest here, the materials on both sides of the lemon zest are exactly the same. So the lemon essence inside the lemon is the same as the essence of the lemon on the outside of it within a very small area. And once you stir it, it introduces vodka into that localized area and now the extraction can happen again. Now the reason why you want to keep it in a dark place is you don’t want these chemicals that you’re extracting to start to break down. You have a lot of oils in there, a lot of sugar, a lot of other compounds, and if they hit some light they’re going to start to deteriorate. So you want to preserve the freshness and vibrancy of your infusion.
So now let’s examine something else that’s going to have an impact on the rate of infusion for you and that just general surface area. So to make this easier to explain, let’s take out this simple cube of fruit that we have here. And the way you’re going to calculate surface area is just measure up all the sides, add them all up, and essentially that’s going to be your surface area. So for this we have 2 in. wide by 2 in. long, and 2 in. high, and your total surface area for this for each side is going to be 24 sq. in. Now to increase the amount of surface area that we have, a simple way to do that is just to cut it right down the center. And what that’s going to do is it’s going to expose that center that was previously still together and increase the amount of surface area that we are infusing. So the new surface area that we have is 32 sq. in. Now if you look at the two pieces, the 32 sq. in. gives us a lot more surface area for alcohol to interact with the infused the material. And what’s going to happen is that extractions will be a lot faster. So the amount of surface area that we have increased just by that one simple cut is 33%.
So let’s take a better look at our example here. So we’re infusing lemon peels into vodka. And the thickness of the lemon peels is not very thick at all. So can’t really cut it in half lengthwise, and even if you did it on the width, it doesn’t really expose a lot of more of the surface area here. Now we could also do even smaller cuts, like a julienne or small dice but it’s not really going to add a lot to the overall essence of the infusion. They will start to add up after time, but the easier thing to go about this is simply to just add more material. So in this case, adding more lemon zest will make the infusion happen faster. So here’s an example: just by adding more material to it, it cuts down the time from three (3) days with one (1) lemon to one (1) day with three (3) lemon skins, and it achieves the same goal. Now, let’s take a look at if we hold all the other things constant. So let’s say we have the one (1) lemon for five (5) days or the three (3) lemons for (5) days. The overall lemon quality and the lemon flavor is going to be much more pronounced after the end of five days. Now just to make it simple: the amount of flavor that you can extract from a material is going to be much higher the higher the mass of the product is. So very simply, the more lemons you can put in this, the higher the extraction, the more lemon-ification is going to happen.
