They announced their 2013 Cider Festival a few weeks ago but their web site now includes the menu which can be downloaded here.
I'm quite excited by this list compared to 2012 as there is only one weak (4%) one this list, the majority of them being between 5% and 7%. There are also three Gwynt Y Ddraig entries.
I've no idea what the prices will be, but currently a 7% cider counts as an "Ultra Premium" guest product at £2.75 in the lowest price band (£2.15 for a "Standard" guest). I'm sure that last year they had a blanket price for the festival ciders.
