    Euro 2024: German beer strength warning for British fans.

    ....and are served in 500ml glasses. 500ml of 5% beer has the same alcohol as an imperial pint of 4.4%... (never mind the fact that, gasp, premium lager is available in the UK....)

    Blackberry Sour

    One of the most critical factors is pitching rate, Philly Sour is really sensitive to pitch rate which is why people have problems with reusing it. Just going from 1bn cells/litre to 2bn cells/litre can increase the final pH by 0.2-0.3. See the suigeneris blogs I linked to over in the main HBT...

    Vienna Lager Yeast

    You shouldn't be afraid to brew lager yeasts at "ale" temperatures, the Frohberg group of lager yeasts (which includes all the main commercial ones) are pretty temperature tolerant. There's an epic thread on the subject here ...

    The London Pride / ESB partigyle rabbit hole

    Yep, that's the yeast - and the White Labs and Wyeast strains just don't have much of it, they're rather dull in comparison to the real thing. Either use Imperial Pub which has a lot more of the marmalade thing, or just harvest from 1845. I hadn't realised they'd kept the open fermenters going...

    Heriot-Watt Brewing and Distilling course

    Well centrifugation isn't a filtration method.... And you have to distinguish between "good" haze which is fine and resistant to methods like centrifugation, and "bad" haze from flour and yeast and god knows what other coarse ...err "crud".

    Heat Source Pumps.

    Yep - in fact I'm out of date, at Christmas it was 3.495GW operational, 3.752GW under construction, and another 24.501GW with planning permission. https://www.renewableuk.com/news/660775/Pipeline-of-UK-energy-storage-projects-grows-by-two-thirds-over-last-12-months.htm The thing with these...

    Heat Source Pumps.

    The technology has been there for a while, it's more about tariffs - Octopus are way ahead on this compared to the traditional electricity companies, such that they're pretty much the only sensible option if you're trying to do these kinds of things. Nothing to do with government - Octopus are...

    Heat Source Pumps.

    Of course - in the same way that EVs are not right for a non-negligible minority of the population. But we have the same problem of misinformation - which is probably worse for heat pumps, we don't have Top Gear for home heating - which makes the ordinary person think that this is something that...

    Meanbrews analysis of winning Old Ale recipes

    I appreciate the intent but if ever a "style" was not suited to a data-driven approach it is Old Ale, which despite what the BJCP may make out, in the UK varies across time and geography so that in effect the same phrase gets applied to three completely different styles of beer. If you try to...

    New Fresh Ale category claimed

    There's at least two separate problems in that list. Events in a temporary location of which the wedding marquee is the classic example but maybe a ceilidh in the village hall is another, have their own problems. You often have limited access to the location before the event which isn't ideal...

    allinson yeast

    These are all things that seem to be true of US bread yeast, but in my experience of actually brewing with European bread yeast, they don't seem to really apply here. But as most discussion is about US bread yeast, people just assume that European bread yeast is the same and it just isn't.

    Hops Storage

    Storing under CO2 at ambient? The best answer is - try to avoid having open packs by being smart about hop usage. Much of the time I only have a packet of bittering hops open as my standard brew is some bittering and then a 100g pack of a single hop in 14 or 18 litres. Crossmyloof are probably...

    Heat Source Pumps.

    But for almost all of those 15% it is "just" some loft insulation which is not a particularly big or complicated job to add, it's not like adding cavity insulation. It's going to be what <10% of the cost of the project? And as I keep saying - radiators being "not up to the job" is just not a...

    Heat Source Pumps.

    And you think -10 is not unknown in Norway, where half of all houses have heat pumps? Or Canada? There are specialist cold-weather heatpumps, but they do cost more. You're not an ideal case though in terms of who would be an early-adopter in the UK. It's a token, that does work, but it doesn't...

    Heat Source Pumps.

    You don't need to reduce the boiler temperature, high-temperature heat pumps produce water at the same temperature as a boiler so your current radiators will do just fine. But it's only recently that they've become mainstream, so a lot of installers aren't really aware of them (and/or would...

    Hop plants/rhizomes - growing report

    Fair enough, sounds about right, it was just a thought based on the flavour comment. I don't know if it's the photos but both cones and leaves look rather pale, they could perhaps benefit from some nitrogen??

    Hop plants/rhizomes - growing report

    Commercial brewers here using green hops (ie undried) work on adding 7x what they would use of dried hops, in the US they seem to work on 5-6x, either way - there's a lot of water in them. Also to my eyes they look a touch under-ripe in your photo.

    Hop plants/rhizomes - growing report

    This is another reminder that East Kent Goldings is not a variety, it's a legal designation for specific clones of Goldings grown in a particular geographic area, in the same way as Champagne or Parma ham or Jersey Royal potatoes are tied to a specific area ...

    Heat Source Pumps.

    And as has been discussed several times, such fears are overblown. In the real world 85% of UK houses don't need additional insulation, the remaining 15% generally just need extra loft insulation which is something that is a good idea regardless of how you're heating the house...

    Heat Source Pumps.

    Octopus prices start at £500 after the subsidy, they say average installation cost is £5,565 : https://octopus.energy/heat-pump-FAQ/ No you don't - high-temperature heat pumps produce water at the same temperature as a boiler, so can use exactly the same radiators. You're still using a lot...
