sunlight damage

[rangaz]

started drinking a new batch of ginger beer today. they were left fermenting in the bottle out in the sun to keep them warmer. the ones in dark bottles taste fine but the clear bottles have got an extra taste to them. it isnt severe and they are still very drinkable but i thought maybe it was something to do with the extra light because i remember reading somewhere that beer shouldnt be left in clear bottles in sunlight.
