Don't be put off my the price of Starsan. You use it in such little quantity that 1 bottle of the concentrate will last for years!
I also bought a 5l bottle of water from the supermarket (c. ���ã2) - use the water in the brewing or just make up the bottle into 5l diluted Starsan. Great for use in large quantity for sanitising FVs or corny kegs etc.
... and don't worry when it goes cloudy. As long as the PH is still low then it'll still work. You'll need some PH strips for this - dirt cheap off fleabay will be fine for this!
Other than that..
Patience - definitely.
Method - get the process correct and repeatable every time.
Resilience - eventually something will go wrong and you'll lose a batch to infection.
and most importantly... enjoy it!
Cheers!
DA
Cheers. Good idea. How long does the Starsan last once mixed with water?
Anybody know? Once I've cleaned with Starsan can I bottle it and use again in say a month?
