Starsan to Water Mixing Ratios (Aka how much starsan?)

Post by XXXXX » 3 years ago

Hi brewers,

I've decided to put together a list of common starsan mix quantities for quick reference.

This is as much a quick reference for me as anyone else haha... Saves me having to do the math each time.

Per the instructions on the bottle, we use 1oz starsan per 5 gallons of water.

So here we go with some examples of how much starsan to use in different volumes of water:

5 gallons water / 1oz or 30mL starsan
1 gallon water / 1/5 oz or 6mL starsan
3.785 liters water / 6mL of starsan (same as a gallon)
1 liter (1L) water / 1.6mL starsan
750 mL (0.75L) / 1.2mL starsan
500 mL (0.5L) water / 0.8mL starsan
250 mL (0.25L) water / 0.4mL starsan
1 cup water (236mL) water / 0.38mL starsan
1/2 cup (118mL) water / 0.19mL starsan

The best way (or easiest way) to measure tiny volumes is to get a syringe at the pharmacy. They're cheap and reusable.

If you're using a syringe then it might be measured in cc's. But fear not, since 1 cc (cm3), cubic centimeter is equal to 1mL (0.001L).

I usually round up to err on the side of caution.

All the best! (And feel free to double-check my math!)
Mmmm... Beer... *drool*

My starsan concentrate is in a dispensing/measure type. 5 ml easily measures out, to be added to 3 litres of water.

I make 5 gallons and store it in a stainless keg.

I use a 2l Growler bottle and mix in 3ml with it. Once I get my brewing shelf up and running I will probably get a low and wide tote to fill that I can swirl things in.
