I've sent a six-pack to my sister for cellaring, which is something I'll do every year now. The intention is for her to give me one of each every year, so it won't too be long before I'm drinking 7 ESVAs of different vintage each time the new one comes out.

Could be a change in the fundamental laws of physics governing our universe?

Ooh, does it tell you the pre-boil gravity of each?

Yep, and it's a bit different this time 'round, but I like them both.

Are there any other variables that could have changed, such as losses or boil-off rate?

I also have a "system" that sees my recycling PETs. Ideally I discard three or four based on a few factors (including whether they look stressed at the bottom) each time I bottle, and when my box of discarded ones is full I buy a new box to replace them.

Me too, but with magnum for bittering (of course) and harvested nottingham yeast

2018, from the actual ROTM pack

That or insulated cupboards or something the least

PET, because they are light and don't explode, but also I do pour into a glass

My shed is all hot again which I think kicked off further fermentation in a few of my bottled batches, and now the fusel alcohol is giving me a headache

@PB2, you might know the recipe, and sharing is caring ... care to help out?

Perhaps you could do what I do @Beerlust - make awesome all grain beer all year long, then buy the ESVA ROTM pack from Coopers when it comes out. If anyone does have a recipe for something similar then I'll brew it up. My main issue is that I wouldn't know how to clone the ESVA myself.

Dear lord this is a great brew Just enjoying another and I love the whole process, from trying the new vintage, to buying the ROTM pack, to harvesting the yeast, to enjoying the results for months to come. It’s not an AG brew, but damned if I could do half as good myself anyway.
