This thread is very strange.
All the Big Helga I've tried in Melbourne (where it's brewed actually in our outer suburbs - at the Garage Brewery in Dandenong) has tasted clean, not sour at all and has a very subtle, mild American style hop character. There seems to be a real inconsistency with the fresh stuff we're getting here in Vic vs the 'rough' and 'sour' beer being drunk in places like WA & QLD? Could be handling, low turnover, old kegs or maybe some of the batches of late have been crapola? Weird one. Could this be another Matilda Bay repeat of the the infamous 'Sebastian' episode? (A notorious Dunkelweizen beer that was ok in first weeks then went south all around the country?).
The stuff I had at Microbrewers showcase was magnificent. But was quite a different beer - being unpasteurised (not heat treated) so the hop character really came through. Have tried it on tap elsewhere in Melbourne without issue. The commercial one is very low on hop, but it's still subtly there.
Hopper.
