I was reading a column in the Guardian " Life and Style " 17th February. The column was about Chef's and Food Writers preferences for " Off Brand " ingredients that they use and recommend. The article was mainly foodstuffs, but in the comments section there were some interesting gems, and a discussion about various supermarket beers. Well worth scrolling through.
Gems such as Lidl own brand IPA is repackaged " Radical Road " and a lot of Lidl beers are brewed by Stewart Brewery. Aldi tends to be William Brothers / Drygate, and a discussion o f the various German beers they sell with recommendations and criticisms of various brews. It's a bit of a trawl through the comments, but as previously mentioned, there's some useful information there.
