I have about 40 x 1.5 liter bottles of water in my refrigerators.
All that water adds thermal mass, and keeps the fridge temps very even.
I buy 6 of those 20-liter water jugs from a delivery company.
Then I fill up all 40 of the 1.5-liter bottles.
And now I am ready for the long holiday.
I do not add lemon to the water.
Instead, I brew Chinese tea, and add ice to the tea, and then I can top up the ice-tea glasses with 0.5 degree C water from the fridge, as required.
This is all that I will be consuming, in the way of beverage, this weekend.
Just Chinese Tea from Sichuan, and Ice Water from the fridge.
The water delivery company is a good one, too.
