Hi Guys,
Once again, some good provocative comments....
Regarding hopping rates - these are still basically the same as they have always been, except now we are adding even more late in the process. In the old days we primarily added bittering hops and then used the hop back. Currently we are actually only adding a small amount of bittering hops (EKG), then we have a big addition in the whirlpool (US Cascade) and then we in fact add more US Cascade in the hopback than we previously did. The Galaxy plays the same role as the Chinook did, which is a small addition to help "lift" the hoppiness. We keep tabs on this as that hop can completely take over the beer; it is about balance. Currently we are playing around with some NZ Cascade in the mix, but this is not a permanent thing (just giving them a little run to check out the flavour).
The Tasmanian hop changeover hasn't yet occured; it's still a couple of years away, but after next crop we may be doing a bit of blending to play around.
So as far as using less hops I can attest that we buy an absolute #$%*load of them.
Regarding the beer spec, the last few years we have actually lifted the AE (final gravity) and IBU up to keep it around the 38 - 40 mark vs. where we were sitting for a while (35IBU). Not necessarily saying we are trying to make a bigger beer, but just highlighting how we tweak things over time depending on how the hops are tasting/balance is playing out.
So there is some info from the horses mouth.... The comments about freshness are definitely valid, though. Fingers crossed most of the time the beer is tasting great, but then I know it leaves our warehouse on a truck, goes across to the distributor, sits in their warehouse, hopefully they rotate stock correctly (we keep tabs on this), then gets delivered to a pub where it might sit in a roasting hot cellar, then we hope the cellar person rotates the stock, and then we hope the lines are clean, and then we hope the beer turns over quick..... so this is definitely not an ideal world....
Cheers, and keep drinking good beer,
Alex
