Are you saying that tierra group provides you with a concentrate that still has plant material in it ?
We do a 100 % agave spirit , we bring in 100% agave syrup sourced from Jalisco mexico, tote from breckinridge $4650.00 It does a good job our first batch ever took a bronze ,at the great american international, we are on our 15th run now and it is much better so Im hoping for good things. As good as it is it still isn't, if that makes sense, I feel it s still missing that something . I have come to the conclusion that indeed i am missing those ever important esters you can only get from the plant.
Are you using a single yeast single pitch or 2 yeasts and nutrients double pitch ?
