I haven't been doing diy for very long. I finally nailed an adv. I have made at most 50ml at a time, and is pretty good immediately but better after about a week. We'll I decided to do 120ml this time so I wouldn't have to make it as soon. I do use a juice calculator and went back and verified the calculations. But it has been a week and it doesn't taste like the smaller batches. When you do a larger batch does it need to steep longer? The only thing different is the 120 is glass (brown) and the 50's have all been the plastic squeeze type. Could that be the difference?
