To me this sounds like a largely politicised issue from a new owner who's not satisfied with the deal they got. I have no doubt that there are bases behind the claims but it worries me when articles cite things like:
Substandard malt by Joe White leaves brewers bitter - not by those on this forum it seems. The article doesn't mention brewers being bitter at all.
BREWERS have been routinely supplied with substandard malt - substandard perhaps, but by what standard?
... controversial Swiss commodities group Glencore - adding extra adjectives always put an immediate slant on the article, especially with a word like 'controversial' which immediately implies that foul play is afoot
I have a feeling there would have been a few instances where wrong product was sent (wrong barley for example) but I'm guessing these were isolated cases. A mining company I used to work for stated that they would, about once a year, accidentally ship a product that was not to spec. I'm talking a few hundred tousand tonnes of product. Because of the quality testing in place, it's the customer who recognises this first and the cause is normally a clerical error drawing from the wrong stockpile or putting the wrong thing there in the first place.
I'm guessing the issue is more about false reporting of quality in some instances, and hoping the customer won't find out 2 row is being sent instead of 4 row for example. If the issue was genuinly concerning then the big players surely would have rejected the malt based on their own internal testing, which they certainly would have performed. If it was tested as being an appropriate spec for 250kl of beer, then even if it was slightly out of the stated spec it would still have been ok for the brew. It's not something a brewery would take a gamble on. If the brewers keep accepting the product, then perhaps JW got a little looser on their quality control because they knew it was all that was required for certain customers. This wouldn't surprise me at all.
Who knows really, I'm doing a lot of speculating. I use JW for all my bases and I suppose at least now, as Manticle said, I can have more faith that I'll be getting a decent product because this scrutiny has been raised by the new owners. I'm very keen to see if output does drop by 40% and they do actually spend $30 mil, because that's a big call for a business to make (lost turnover and unplanned capital). I'm hoping it's not just an announcement strategy to add more weight to the court case.
