Hi - after some advice..... My 80 shilling I bottled with too little sugar and although its carbed up, I hear a hiss when opening, its pretty lifeless and flat. Im going to add a carbonation drop to each bottle and recap (These are the carbonation drops that suggest 2 per 500ml bottle, so I figure 1 should be enough to give it that little boost). I've ordered a bag from amazon and was about to bring the bottles in from the garage to the house to warm up but then I thought am I best to add the drop to cold bottles? So the plan will be keep 'em cold till Thursday, crack them open 1 at a time, add a drop then recap. Then the next morning once they are warmed back up, invert the bottle to rouse the yeast. Is this the best way to do this, or should i get them out the fridge ASAP to warm up the yeast so its not sat dormant for too long?
