this is my second batch of brew, after my first batch was really bad and i was told i contaminated the batch i was crazy clean and made everything spotless :rockin: . so here is my question, my starting specific gravity was 1030. the instructions for this brew said it should be 1048 - 1052. not knowing what to do my friend and i proceeded to move on to adding the yeast and fermenting. its been 9 days and i took another specifig gravity reading this reading came out at 1020. i did the calculation and has a ABV of 1.3. is this right or do i leave to ferment longer? if anyone can help i would apreciate it.
thanks
