Geronimo and Yeti Hit the Road

We’re across with family for Christmas, and although I toyed with the idea of taking a couple of party kegs with me I decided against it in the end; it’s a short visit, I’ve only one decent dispense tap, and I still haven’t sourced (let alone tested) a Sodastream bottle for mobile use. All of which meant that I could put it off no longer, it was time to finally break out the counter-pressure bottle filler I thought I badly needed when I started out kegging.

It was actually fairly easy to rig up, with the most difficult part being a lack of compatible ¼” Duotight connectors, but that was soon overcome with a section of slightly smaller diameter beer line and a heat gun.

Purging and filling the bottles too was fairly easy. I started with Geronimo, which had been sitting at 15 PSI / 4℃ for 6 days by this point. The first bottle filled with just half an inch of foam thanks to some bubbles in the line, but subsequent bottles had no head at all. Maybe I should have tested the brew first – was it still not quite ready?

After 7 bottles were done I switched over to sanitiser and flushed the lines with about a litres, before switching to Yeti and again flushing through about half a litre. For this one I used 330 ml clear lager bottles, and these didn’t want to stay upright as readily as Geronimo’s 500 ml standard brown flasks. They were also a tad shorter, which meant the counter-pressure filler’s (CPF henceforth) bung had to be carefully moved to the extreme end of travel and monitored for blow-out. The carbonation was a little higher on Yeti, and combined with the narrower bottles I found that foam made its way more readily up the neck than with Geronimo. It’s difficult when you’ve only got one gas line running into the Kegerator…

All-in I had a positive experience with the CPF. It was a bit messy in places and took a few minutes to clean and sanitise, but on the whole I’d use it again, though perhaps for bigger batches. One thing I will definitely do differently next time is to rig up some kind of CPF suspender, because it’s quite a big old lump to delicately balance on an empty bottle while capping the one you’ve just filled. Live and learn.

Yeti and Geronimo, ready to go

Geronimo III: First Taste

Great hop flavour, maybe 5% too bitter for the style. Aroma could do with being more floral too. Mouthfeel isn’t quite there yet and neither is carbonation, so I’ll give it another 2 days at 15 PSI and then take it down to 10 since I’ll be away over the festive period. Generally OK.
