just finished my first batch. Used 59ml(2 oz) bacardi and came out with maybe 20 or so ml at end. Is this low!?!? It def isnt 34 ml. I also used a garlic press and squeezed the hell out of the cheese cloth I used

I simmered for 23.5 minutes and temp was 170 that dipped a few times to 166 or so. Took 4 minutes to get up to temp that is why I did extra 3.5
