How to make your taste buds disappear completely


Damn this stuff is bitter. I mean coat the top of your mouth make you pull a funny face, still in the back of your throat an hour later bitter. It makes even the most intense American hop bomb taste like a pint of mild. It's hard to see the point of it. I read a while back that plenty of rich malts were used to balance the intense hopping in this lightweight beer, and at the time this intrigued me. Was it possible to add that much hops to a beer of a mere 3.5% and make it any way balanced? The answer's no. The hops are so intense they burn, and the body gives up long before it has a chance to contribute anything. It does smell amazing though, and the pungent hops would make you think that you are in for a big heavy hitting alcoholic hop bomb.

Care should be taken when drinking this beer. After I finished the bottle I was ravenous despite having my dinner shortly before. The intense bitterness stimulated my appetite ferociously, and I found myself raiding the fridge before bed for just about anything I could get my hands on. Not one for the diet conscious.

I didn't enjoy it, but as an experiment this beer is superb. It highlights everything that is right with the new breed of craft brewer at work today.

Hardness and alkalinity Part 1

Water hardness and alkalinity are some of the trickier aspects of brewing to get a grip of but the benefits and improvements it can bring to your brewing make it well worth looking into. Suitable water improves every step of the brewing process. I already outlined the importance of calcium in a previous post. This post is a guide to assessing the hardness of your water supply and its suitability for mashing. First we need to get some definitions straight as it is these phrases that often cause the most confusion:

Hardness: This is essentially the concentration of calcium and magnesium in the water. It is divided into two further sets of terms:

Permanent hardness also called non-carbonate hardness. This cannot be removed from the water by simple means. It is made up from calcium and magnesium compounds such as calcium sulphate, magnesium sulphate, calcium chloride and magnesium chloride.

Temporary hardness also called carbonate hardness or alkalinity. This can be removed through the various treatments that brewers use, and is responsible for the lime-scale on household appliances. It is made up of calcium carbonate and calcium bicarbonate.

The significance of the distinction is seen when we consider what the two types of hardness bring to brewing. Carbonate hardness increases mash pH by neutralising the natural acids contributed by the mash, dragging the mash pH away and above the 5.4 that is optimal for malt amylases to work. Non carbonate hardness lowers mash pH and is beneficial to meeting the optimal mash pH.

The contrasting action of these differing forms of hardness leads us to another important term in brewing water chemistry: residual alkalinity. This is the net effect of the water hardness on the mash, and the extent to which the water will have to be treated to meet requirements. For most Irish water supplies carbonate hardness will out-weigh non carbonate hardness and the water will require a degree of treatment to lower the alkalinity.

Water reports state water hardness in 'equivalents' of calcium carbonate or bicarbonate. This is necessary in order to compare the different types of hardness in the water on a equal footing. When compared in this way it is seen that 3.5 equivalents of permanent calcium hardness or 7.5 equivalents of magnesium hardness is required to offset the pH raising effects of 1 equivalent of carbonate hardness. It is clear from these figures that carbonate hardness is very potent at increasing mash pH. If your water supply is low in carbonate hardness it might be possible to offset the residual alkalinity through the addition of calcium sulphate or calcium chloride, which is likely to be added at any rate in order to increase the calcium concentration to a more suitable level. However, if the carbonate hardness is very high, adding calcium to the water will not be sufficient to overcome the residual alkalinity and the carbonate hardness must be removed.

In my next post I will provide some simple methods for estimating alkalinity, and how to remove it.

Bigger than planned

I haven't brewed nearly enough over the last few months. It was time to remedy this with a bang, so last weekend I planned to brew an American IPA. It got away from me a bit  thanks to some overly zealous hopping (is that possible in an American IPA?) and a better than expected extraction of sugar from the mash.

25 litres
5 kg Maris Otter
2 kg Munich malt
500g Cara Munich

35g Galena 13% AA 60 minutes
25g Centennial 10.5% AA  20, 10, 5, 0 minutes

OG 1.078

60 IBU estimated

Saf 05

I gave my mash tun a serious workout and it held up admirably. Once again I treated my water, bring the calcium up to around 160 ppm through additions of calcium sulphate and calcium chloride. I rid myself of around 130 ppm of pesky alkalinity using carbonate reducing solution and everything went very well indeed. I planned for 75% efficiency and an OG of 1.070, but achieved about 80% and ended up with 1.078. Very gratifying but the fact that my last runnings came in at 1.030 indicates that I just can't get the damn fermentable sugar out of the mash tun. The chemistry was perfect; the temperature held at 66 C and pH fell in a spot on 5.4, but the damn grain held on to the sugar. Not to worry. I'm not a penny pincher and have no problem dumping the grain. Perhaps in future I'll do some small beer.

I opted for some first wort hopping because Galena can be a little harsh,  and also the hop rate was quite liberal. I used pellets for the Centennial and had to break out some extra kit to cope with all the pellets. I planned to make a big beer with plenty of rich malt for quite some time, the hope being that the richer Munich malt will provide a decent base for the hops.

Below is a video of Saf 05 yeast hard at work. The wort looks like swamp water because my set up dumps all the break material into the fermenter, but the beer generally drops bright in the end with no ill effects.

Jack Russell not Great Dane

With all the hype around Brewdog's heavy hitting beers it's easy to forget that they produce beer of average strength too. Well, easy for me to forget at any rate because until recently I couldn't get my hands on any of it. This was happily remedied with a recent trip to The Drink Store of Dublin's Stoneybatter. A number of Brewdog beers have turned up there including The Physics and 77 Lager, both of which are lightweights compared to Brewdog's more potent beers, but they do not suffer in the flavour stakes and will stay in my memory just as long as their bigger beers. It is clear that the philosophy of packing in the flavour is avidly adhered to in these beers despite the pedestrian nature of the style, being far closer to the average beer on the street that Brewdog swore not to emulate.

77 Lager is unlike any other lager you will try. The hop choice is not one associated with a lager (Amarillo, I think) but the taste and aroma is very satisfying. I wouldn't class it as a lager on a blind taste and it likely only masquerades as a lager because of a period of cold storage that the majority of ales undergo anyway. It's certainly clean like a lager but the orange fruiy flavours probably undo the work of the lager yeast strain, if indeed one was used.

The Physics falls directly into standard British ale territory, but with more teeth in the form of a surprising bitterness. The malt that drives this beer is superb and probably the best I have tried in quite some time. Crystal and Caramalt is mentioned on the label. I will be seriously looking into this combination to get that juicy, chewy malt aspect into my own beer.

Proper, Proper Job

I knew when I read the back label on the bottle of St Austell's Proper Job I had tried the beer before. The front label tells us that it is 'powerfully hopped', but in general, unless it's BrewDog telling me that, I tend to ignore it, knowing that my idea of powerfully hopped and the average British brewer's idea are two quite distinct things. A further study of the label makes for very interesting reading; Willamette, Chinook and Cascade are listed as the hops employed and it is at this point that punters might have reason to think they have something quite special on their hands. As it turns out this ale is powerfully hopped in a very satisfying manner. Frankly, for a British bottled ale it is astounding, full of hop flavour and resins all wrapped around a satisfying malt base. I could drink this stuff all day, but at 5.5% abv it would take its toll.

I mentioned that I thought I had crossed paths with this beer before, well, I am certain that it is none other than the Marks and Spencer Cornish IPA I tried in London earlier in the year. In that post I begged M & S to unleash this beer on the Irish market, and I will once again reiterate this plea; Take back the Yorkshire Bitter and give us this wonderful IPA instead!

Happy birthday Grandad

The weekend found me visiting the English suburbs of my early childhood for my Grandad's ninetieth birthday. We had a get together involving four generations of my father's side of the family, something that really drives home just how old my grandfather is. He was born in 1919 and spent all his life in the historical town of Egham, except for a stint in the army which found him carrying a Bren gun around the deserts of Africa. That's him on the right in the 1940's, in uniform enjoying a pint of something dark, more than likely Guinness.

Egham is only around 20 miles form London and the most direct route to London from Egham takes you straight past Chiswick on the M4. I discovered this while being ferried to the RealAle.com bricks and mortar shop near Twickenham. Chiswick is of course home to Fuller, Smith & Turner, the producers of any number of great beers, and usually there is some Fuller's to be had in the pub that housed our family get together. I was surprised to find that the biggest seller the pub stocks at the moment is Doom Bar from Sharp's brewery of the Southwest. My uncle had travelled from down that way and was disgusted that a beer from his region was on offer near London. His other options were Courage Best Bitter, which was thin and bland, and Bomardier which surprised me with a distinct and very pleasant English hop flavour I can't say I really noted before. Apparently Doom Bar is the most popular beer the pub has ever stocked, but I can't say I rated it all.

Having checked out their website, my trip to the RealAle.com shop was much anticipated. As it turned out, the website does not do justice to the selection on offer. BrewDog are well represented and I took advantage of this by grabbing some Atlantic IPA, How to Disappear Completely and Storm. American beer was present in force, though a little pricey so I restricted myself to Dogfish Head's Palo Santo Marron and Victory's Storm King Imperial Stout. Out of curiosity I bagged some Thornbridge Brewery Jaipur IPA to see what all the fuss is about and in keeping with the Corninsh beer theme, some St Austell Brewery Proper Job, which I am sure I have tried before, but more about that in a later post.

Barcelona

I know what you're thinking: this is not a city for lovers of beer, and in some respects you'd be correct. You won't find any cask ale here and for the most part the beer on offer is very bland and very cold, but happily the beer consumed in Barcelona, particularly in the heat of an August afternoon hits the spot nicely. You hardly find yourself drinking for gastronomic reasons, more as a means to stay alive, lest thirst and heatstroke kill you. Perhaps I'm being a little melodramatic, but ice cold beer in these conditions really does offer a revival to a body past its thermal comfort zone.

Our hotel was in the Exiample quarter of town, and area north of the old town and built after the old town burst through the city walls during a period of rapid expansion. Exiample sits in stark contrast to its older neighbourhood; a strict grid like lay out of smaller streets crossing larger avenues similar to New York makes for easy navigation, while the Barra Gotic and La Ribera of the old town are a confusing, seemingly random network of small streets that once sat within the old city walls, and savagely bisected by the relentlessly busy La Ramblas. As it turned out the Eixample proved to be an excellent location for beer bars, or 'cervecerias'. The Pilsner Urquell boards outside Mengi Mengi drew us in while out for a stroll after dinner on our first night. Along with quality Czech lager on tap, the bar sported a number of beer fridges stocking a solid if unspectacular selection of beer from Germany and Belgium as well as some Argentinian Quilmes Lager, which I tried for the first time. The Pilsner Urquell came served in a glass from the freezer and, unsurprisingly was very cold indeed. Luckily this lager still gives plenty of flavour at that temperature and it went down very nicely.

Lunch for us generally meant tapas. There are many places around the city to try it, but once again our hotel proved to be right next to one of the best tapas bars in town that also just happened to have a decent beer menu. Cervesia Catalan is a very busy spot, but thankfully our custom of eating quite a bit earlier than the locals meant that getting a table was straight forward. It appeared to be something of an extreme sport later in the evenings when the locals emerged from their labours for a spot of supper. Walls lined with beer bottles surround diners, and good selection is offered on the menu. Standard Spanish lager is available on tap, which I washed down some omelet and potatoes with. I followed this with some Timmerman's Kreik - a mistake I realised too late. Timmerman's appear to be one of the many Belgian brewers out there making a very good living from putting E numbers and fruit syrups into weak lambic, not to mention an unhealthy dose of artificial sweetener. Nasty stuff and a lesson learned. After lunch we exploited the most civilised of Mediterranean traditions - the siesta, a healthy dose of tapas and cold beer aids this no end.

Two minutes west of the Placa de Catalunya will find you in the incongruous medieval hard wood and wrought iron interior of Alt Heidelberg, a German bar serving a decent selection of beer nicely complemented with tasty German fare and traditional local tapas. Once again Pilsner Urquell is the main beer available on tap - a little confusing because the aged menu suggested that other beers are available. The same thing occurred in Mengi Mengi, where the menu would have you believe that Spaten is on draught, but a request for draught beer will get you Pilsner Urquell. It seems that SAB Miller have muscled into the better beer bars and forced all other producers, except for the Spanish macros, from the bar. Confusingly the menus are often not updated, and the waiters will not inform you that the beer you think you are ordering isn't in fact on offer. The highlight of this visit for me was some Samuel Smith's Taddy Porter. It was all brown sugar and treacle, the ordering of which raised a smirk from the waiter who I am sure thought I had taken pot luck from a Spanish language beer menu and didn't realise what I was letting myself in for. I washed down some excellent sauerkraut and bratwurst with the porter and topped it off with a sweet and refreshing Lindeman's Peche - which raised yet another smirk from the waiter.

Our last evening found us enjoying after dinner drinks in D'Or, yet another bar with a respectable beer selection only minutes from our hotel. Large ornate German beer fonts on the tables immediately alert you to the possibility of a decent pint, but it was the more obscure Catalan beers from Cerevesera del Montseny that caught my attention. Nonchalantly dropped in among a list of European beers of note was Lupulus. Thankfully my extensive knowledge of Latin meant that this beer did not slip by and I was rewarded with a healthy dose of American C hops more intense than I ever dreamed of from a Spanish beer, and on top this delight it was bottle conditioned to boot. It was a little soup like but really delivered. Happy with this find I opted for another beer from Cerevesera del Montseny, this time their dark beer described as 'cervesa negra Irlandesa', so it was not hard to see what they were driving at. Unsurprisingly it didn't quite hit the mark, resembling a thin, weaker English stout rather than the fuller Irish interpretation. Once again a funny look met my request for this dark beer. Spanish waiters seem concerned that a punter will, heaven forbid, stumble into a dark beer. This is ice cold lager country after all. A curious thing, but it's nice to know that the waiters have the beer novice's well being at heart.
