11/12/2016 – Good brew day and no hiccups apart from the bin bag of grain springing a leak as I brought it out to the bin. Good runoff this time. Pitched only one bottle of yeast slurry from Hop Bastard, as I might do another brew with the remaining bottle next week. Fantastic aroma. Lovely colour wort.

27/12/2016 – Dry-hopped with 100g Amarillo and 100g Simcoe.

02/01/2017 – Removed the hop bag before going on hols. Normally I’d get ut bottled straight away, but I need to let it settle for a couple of days first.

05/01/2017 – Bottled with 120g glucose (17 litres @ 2.5 vol). Got 12 x 500ml and 13 x 750ml bottles from the batch. Great aroma. And great clarity considering it was dry hopped so heavily.

22/01/2017 – A bit soon to be tasting probably, but there’s a flavour here I wasn’t happy with. Not sure if it’s a green beer flavour, or something else. Will taste again in a couple of weeks.

07/02/2017 – Now tasting great. Harshness has disappeared. Even the bitterness seems perfect. Lovely hoppy flavours. Could turn out to be the best rendition yet.
