The most striking thing was just how little difference there really was. The big tank of hot water, the shiny metal mash tun and the gas-fired boiler were all bigger, obviously, but fundamentally the same three vessels that sit in my own garage and get dragged into place on a brewday. There was a fair bit of underletting that I could certainly see myself adopting for filling the mash tun at home, to avoid some of the frequent interaction between hot gravity-fed water and human flesh, but that probably means extra piping and another pump, so we’ll put that in the “ponder” box for now. On the other hand I noted there was no fancy heated recirculation on the mash tun like I have at home, which is to be fair a bit of a luxury item for me. I admit though I have strange ideas about what constitutes luxury…
When I arrived at the Blackjack brewery the bulk of the malt was sitting ready beside the mash tun, and that’s when it started to sink in just how much bigger this batch would be than the original recipe (about 18 times bigger in fact). I’m used to getting through a full bag of base malt across up to five brewdays, but several full bags were ready to go and once the remainder of pale malt and other additions were weighed out we had another couple of bags to add to them.
We were brewing Phoneticus, an American Pale Ale recipe I made earlier this year at home, and inevitably it would need to be adjusted to adapt to a different brewkit and the availability of certain ingredients. Some careful substitution was all it took though, with an eye to matching the colour, flavours and gravity of the original. Initial indications were good – the colour and gravity matched well and as far as I could tell so did the flavour of the finished wort, but it will be the final product that really confirms if we’ve got it right.
Mashing-in was much more a two-man operation than at home; I always find I need two pairs of hands but rarely have the space (or assistance) necessary. This is where I think the underletting would help me, so tipping in grain and stirring the mixture aren’t hindered by moving the filling hose around and dodging the hot liquor.
Once that was done it was a case of waiting. The time flies when brewing at home because there are a thousand little jobs that I can be doing. Fixing this, cleaning that, moving things around aimlessly, usual brewday stuff. In someone else’s brewery it’s different. They might have their own odd jobs but as a visitor there’s not a lot you can do. Still, 90 minutes eventually passed and we were ready to transfer to the copper. Again, the process was little different to what I’m used to, just bigger, and, naturally, taking slightly longer to move several hundred litres where I have just 60 to deal with. As the level of the wort rose above the heater we fired up the copper and once full, left it to reach the boil while we sorted out the hops…

Huge thanks go to Rob at Blackjack for allowing me to come and fit my own beer into his brewing schedule and take up one of his fermenters for a few days!
