As per title, packs of 4 x 330ml Bottles of Bavaria Premium Pils are just £1.59 at Tesco.
This works out at £1.20 per litre / 65p per pint.
This is brewed in Holland and is 5% ABV. This deal works out cheaper than the other Tesco deal of 24 x 330ml bottles of UK brewed Stella for £10.
This isn't advertised as an offer, so there is no expiry date as such.
