I was wondering if any of you have made use of HopUnion's IBU testing service? I sent in a few of my commercial brews as well as a home brew batch out of curiosity. I thought it would be interesting to collect a few data points from other people who had analysis done on their homebrew batches.
I sent in a DIPA from a 21.5 liter (5.67 gallon) batch with an OG of 1.074 fermented with 2 packets of S-05
additions were as follows:
60g Summit 15.9% @ 60 mins
50g Simcoe 13% @ 30 mins
25g Columbus 14% @ 15 mins
25g Mosaic 12% @ flame out
25g Centennial 10% @ flame out
25g Amarillo 8.7% @ flame out
I get a strong boil on my system with typically in excess of 10% boil off per hour. As usual, I did a 20 minute hop stand after adding the flame out hops and cooled rapidly (3 minutes or so to get below 90F) to 65 F using my immersion chiller.
BeerSmith2 calculates 161.9 IBU (I understand that this exceeds the solubility of AA in wort and does not include the ~20% reduction in IBU that you see as a result of fermentation and yeast flocculation).
Hop union came back with a reading of 64.9 IBU on a 2 month old bottle conditioned sample which seems reasonable to me.
Anyone else out there with readings to post?
