I tested 'brewing' a cider for the first time a few weeks ago. Since this process was so extremely different from what I am used to with brewing beers I completely forgot to take an OG reading. To be honest the amount of alcohol in the brew usually doesn't matter but since the first question from people always is "How strong is it!?" I thought it might be nice to know.
This is a pear cider where the pears are 'centrifuged', liquid is then heated, cooled and then topped off with english cider yeast.
My first thought was to make a new smaller batch and test this, but don't have any more of the same types of pears (from own tree).
Is there any way to calculate the ABV without having taken the OG reading?
