Atlas Peak - The Cold Soak and the Pump Over

Now that we have the berries in the tank, we would like to pump over about 1/3 of the volume of the tank on day one and 1/3 of the volume of the tank on day two. To do this we will set up a tub below the bottom valve of the tank. Next, open the valve, collect the juice and berries in the bottom of the tub, then pump the mixture over the top and into the tank.
At the top of the tank we will use what is called a pump over device or irrigator to spread the juice and berries evenly over the top. This process will allow us to keep the juice cool and get some nice color extraction as you can see from the picture. At this point there is still no fermentation activity.

We will talk more about fermentation and the conversion of all that sugar that’s produced by the grapes into alcohol in the days to come. For now we will just need to chill out and wait!
