Carbonation stone results after 24hrs 

Great work, pal. I didn't realise these were so effective. More gadgets coming my way this summer. Cheers!

Nice one Graham. Sorry had to watch this on 3 time's. First I was watching your brews bubbling away,, the second I was looking at all your whiskeys,, the third I actually got to listen to your review of the finished results 😅. Looking forward to the full IPA review. Cheers 👍
