I tried Sapporo's "Luxurious Off" (オフの贅沢) near-beer the other day. Its main selling point is 70% cut in carbohydrates. It falls into the happoshu category of near-beer (read low malt content). It also boasts partial use of roasted malt and that all malt and hops are cultivated under collaborative deals.
Not bad, but low malt, low carbohydrate takes a toll on taste.
On the label:
"The tasty low-carbohydrate brew made with roasted malt for deep and rich barley flavor."
