I've finally replaced my popcorn popper coffee roaster with the Hottop KN-8828B drum roaster. Why? The most pressing reason was the need for larger batch sizes. The Poppery could only handle up to 4.2 ounces at a time, and doing back-to-back roasts made the second batch go way too quickly- often with no time between the first and second crack. You could approximate a roast profile manually by flipping the heat switch on/off, but most of the time its just roasted too quickly- and you have several under developed beans.

Why the Hottop? It does 9oz at a time, very evenly. It does internal voltage monitoring, so you don't need to mess with a Variac. I'm also into light roast coffee lately, and the Hottop has a really slick cooling cycle to stop the roast really quickly. Here's a short clip initiating the cool mode manually- embedded below. The high pitches "pop" sounds are the beans in second crack (this particular bean called for a darker roast than most I favor):



Its quieter than the Poppery, so hearing subtle cracks is not an issue- and it has a nice viewing window to keep tabs on progress.

But it does have its down sides. It is higher maintenance than a Poppery, with not one but two proprietary filters that eventually need replacing. It also has anti-lawsuit programming: when certain temperatures are reached, you need to hit a button within a short timeframe or it dumps the beans, whether you like it or not (due to potential fire hazard.) Lastly, the internal temperature monitoring is inaccurate, and while there is a fully programmable model, it should be avoided.

However, I am happy with it. It makes really good coffee with practically no effort (if you choose to roast on Auto), yet has plenty of room to grow with its option to save roast profiles. If you're just getting into coffee roasting, I'd still suggest a popcorn popper to learn the ropes. Once you graduate from that, the Hottop is a solid machine.

Continuing this entry into a potential series, here's another update I just got in email, regarding our 16 month old's first day in "music" class:

Music class wasn't what I was expecting, but it is good. I'm glad we're taking it. When we got to the rec center, there were several other rooms with aerobics classes going on -- [baby] really wanted to be in those classes, because the music was blaring, people were moving, and the rhythm was really fast.

Our class was small, which is good for a first class for her, but I didn't expect it to be that small. Also, there is only about 5 mins when actual music is played -- the rest is the teacher singing and using body movements (clapping, tapping, swinging arms, marching, etc.) or music instruments that are passed out. Everyone was really, really nice, including the teacher, moms and kids. There was one young mom with a 2.5 yr old boy and a 4yr old girl - they took the class before. Another mom who looked about my age with a 20month old son. And then a nanny with 2 little girls - one in a stroller (about 6months maybe) and the other about 2 years old I'd guess. And then the teacher has a 20month old but he was asleep in the car with his dad apparently. So the size was good. The room was small and depressing, but I guess that's what you get for a public facility. [baby] just stared at everything the first 10 mins and then when there was an exercise where they sing a lullabye and everyone pretends to sleep, she started to cry hard. I explained that she doesn't like sleep, so the 4 year old shouted, wake up! and [baby] stopped crying because everyone woke up. Everyone was nice about it and very sympathetic. Then they passed out these eggs ([3yo cousin] had them - you shake them) and [baby] liked those, but kept wanted to trade me for my eggs. Shake, then trade, shake, then trade, shake then trade. When it was time to turn in the eggs, the tears came again, but it wasn't as bad.

Then the teacher turned on the music and passed out a bunch of different instruments to choose from - maracas, symbols, etc. I gave [baby] maracas and she seemed to like them. We also had a part when we get drumsticks and a thing to beat them with, which she also liked, but again, cried when we had to give them up. She was happiest when the music played and freestyle dance could occur. The teacher seemed impressed with her "microbeat" rhythm during the freestyle portion. Then at the end of the class she wanted more more more. I asked her if she had fun and she nodded. She was in a really good mood the rest of the morning so i'm assuming it was a success, especially for her first organized class.

My car is down getting the tires rotated now, so we'll pick it up after [baby] gets her nap and eats her lunch. She went down around 1:10. I put her in about 12:45. She didn't cry, but just played for a long time with bunny. Bunny must have been very bad, because she was scolding her quite a bit. Poor bunny.

I took a quick video of the bottomless portafilter in action this morning. Slightly fast extraction, one tick tighter on the grinder would have been ideal but I was in a rush.

Friday Oct 24, 2008



I've been using the same espresso machine for a while now, but about a year ago shelved the hand grinder for a Rocky doserless. The combination produces very good shots when I have a good roast, but on occasion, I get a bad extraction when I know the beans are fine, the grind is fine, and the distribution and tamping felt fine. In an effort to get some answers, I decided to convert my portafilter to a bottomless by removing the material below the basket.

Its an obvious next step, but I've held off for a while because I feared it would be difficult to produce decent results without a drill press or dedicating a whole afternoon (the most common approach based on my quick research seems to be drilling a series of holes until the bottom almost falls out, a horribly messy and laborious task.) However once I looked closer, and realized the portafilter is made of soft brass, it was obvious I had a much better tool for the task, a jigsaw:



After clamping the portafilter to a bench, I drilled a couple of pilot holes (the first one wasn't close enough to the wall for my liking), then just let the jigsaw blade follow the inside wall around the circumference. The photo above shows this process half way through, at which point I repositioned the portafilter at a different angle to better reach the other half. Once the center was removed, I used a Dremel (a tool I once used to cut holes in 3/4" ply, I'll admit) with a grinding bit to clean up the rough edges. It literally took 5 minutes to complete.

The results? The first shot I pulled was a spurter, something that may have shown itself as blonding pre-bottomless, or maybe not at all. I thought it was the result of underfilling the basket, so on the second shot, I added more coffee and repeated. Bingo! Near perfect looking extraction (pictured at top), awesome crema, delicious shot. Apparently eyeballing the fill-level doesn't cut it when you bounce back and forth between different types of beans and roast levels every few shots- some clump more than others due to static electricity and perhaps other factors. I'll be using my scale more while switching beans until I get this under control. And definitely look forward to the immediate feedback I get via the bottomless portafilter. Why manufacturers don't make them standard these days in a mystery.

In the background, a Micropolis 2.1GB differential SCSI drive. In the foreground, a 2GB MiniSD card. The difference between them: 15 years, something north of 5 pounds, and $900. Go Moore's Law! In retrospect, I'm surprised my beige box PC had enough juice to spin that thing.



I wish I recorded the startup sounds that drive made prior to extracting the platters, head assembly, and rare earth magnets. I recall it sounding something like a crash and helicopter. Would have made a great music video.

Linda's giving me some grief- again- about my thermometer collection entry, but I think its just a thinly veiled bout of jealousy. Hey Linda, do you know the temperature of your koi pond to the tenth degree fahrenheit? I rest my case. :-D

I would like to see her get some rest before the weekend though (as opposed to nervously refreshing the stats counter like we both did far too long around our 100k blog entries milestone. So if you're a Sun employee and don't already have a blog, now's your chance to earn yourself some delicious interweb fame.

To supplement my somewhat expensive wine club purchases (2007 was Turley, Reynolds Family, Rhys. 2008 will be Rhys and Ridge Monte Bello)-- and my insanely expensive home addition-- I've been leaning heavily on the affordable K&L staff pics, which this last purchase is large based on. (and yes, they are strongly biased towards Aussie wines, but I'm digging them lately- especially for their value.) Besides the Kim Crawford- which had a solid 2006 vintage- these are all new to me. I've found plenty wines that are readily available I'd consider daily drinkers, but there's still a never-ending stream of wines I've never tried. These take priority. If any of you have tried stuff from this list, I'd love to hear your comments...

Over the holiday break, Igor was kind enough to bring back this 15(?) year old Pálenka his grandfather made in Slovakia. Apparently its common there for people to ferment their own fruit mashes, then bring them to community distillers for finishing. How cool is that? This particular pálenka was made with apples, plums, and "some other stuff".

Although I have a fairly extensive home bar, I'm no spirits expert. I have however made my own beer and wine for longer than most things hold my interest-- and its with unfortunate consistency that other's homebrew is usually crap, in my not so humble opinion. So I was excited when I popped the swing top to wiff a tasty aroma of green apples, raisins and spice. Finally tried it last night and am impressed! Cut with some water (and no ice of course), the flavor reflects the smell: gobs of spice, ripe fruit, and apples. It smells a lot like a Dewazakura sake actually. It would make a great liquor for mixers with its neutral flavor profile.

Seriously considering spending a few months in Slovakia to apprentice under Grandfather Minar for the spirits and Grandfather Macsadi for the smoked sausages. *drool*

For the past several years, I've made this egg nog recipe for my family holiday get together. The first year was just for fun, each subsequent year was at the demand of its numerous fans. It is delicious-- and a great way to find out who might be pregnant (due to avoiding raw eggs :)). Posted here verbatim from a snippet I saved from the hbd.org mailing list (Jeff is (was?) one of the primary useful contributors to the list- thanks again Jeff.)

Date: Wed, 10 Dec 2003 13:33:08 -0500
From: Jeff Renner 
Subject: Egg Nog recipe

It's been suggested that it's time to repost my father's egg nog 
recipe.  I posted it three years ago, and got a great response.  I 
reposted it last year with a little additional history that I was 
pleased to find out.  Hope this will become part of your holiday 
tradition as it is ours.

BTW, I notice in rereading this that I have impugned Old Forester 
bourbon.  It is a fine, old-fashioned bourbon that I like, and it 
works fine in this recipe.

Jeff

==============


My father was not a big drinker or a cook, but he was famous among 
friends and family for his egg nog.  It had a kick.  It was an old 
recipe that he modified (probably increased the booze!) from one in a 
magazine ad for Four Roses Blended Bourbon in the 1930's or 40's. 
Straight bourbon is much to be preferred.

Last evening I took a double batch to a potluck party. I made a 
further modification - an inadvertent, serendipitous mistake, that 
made it much better as a casual drinking egg nog.  I used twice the 
proper amount of half and half (resulting in proportionally half the 
eggs, sugar and liquor). Strangely, it seemed still to be well 
balanced. The original one is twice as strong and is a wonderful 
drink, but the flavor of the liquor is more evident and it must be 
drunk with more caution.  More like a cocktail, I guess.  I like them 
both, but I think that the milder one is better suited to casual 
drinking, especially by people who don't like the full flavor of 
whiskey.  And they are both easy enough to make that you'll never buy 
that horrible stuff from the grocery store again.


Harry Renner's Egg Nog

6 eggs, separated
3/4 cup sugar (set aside 1/4 cup)
1 qt. cereal milk [half and half, or one pint each milk and whipping cream]
1 cup straight bourbon
2 oz. Jamaican dark rum

Beat egg whites until stiff (RAMA NOTE: BEAT UNTIL _SOFT_ PEAKS,  
OR YOUR EGG NOG WILL SEPARATE LIKE A POORLY MADE CAPPUCCINO), 
fold or beat in 1/4 cup sugar.  Set aside.  
Beat egg yolks with 1/2 cup sugar, fold into egg white mix. 
Add cereal milk, bourbon and rum.  Serve topped with grated nutmeg.

The mistake I made was to use a *quart* each of skim milk and 
whipping cream (actually I made a double batch; or was it a 
quadruple?).

Dad always used Myer's rum and Old Forester bourbon, but if you are 
making it full strength and will be able to taste the liquor, better 
bourbon will make a difference.  Two years ago we used Knob Creek 
(~$25) and the difference was remarkable.  Jim Beam Black Label 
(~$15) or Wild Turkey 101 (~$18) would be two other, less expensive, 
but still somewhat premium choices.  Of course, these three are 
higher proof, so drink accordingly.  I suspect there are better 
choices than Myer's rum, too, but it has served us well.

And now an amusing anecdote for your holiday enjoyment:

Scene: a streetcar in Cincinnati, circa 1950.
Characters:  Little four-year-old Jeff and his grandma, returning 
from downtown Christmas shopping, and other passengers.

Jeff, in a loud voice:  "Grandma, don't forget you said that you 
needed to stop and get rummy for the egg noggin!"

Grandma and passengers laugh.

Jeff feels very embarrassed and the memory is seared in his brain, 
even though no one else remembers.

Happy holidays!

Jeff

Among the people I sent it to was Gary Regan, author of a number of 
fine books on whiskies and cocktails ( http://www.ardentspirits.com). 
He sent me this email:

Hi Jeff:

I wrote to Dale DeGroff, and sure enough, the original recipe came 
from a relative of his!  Here's what he wrote back:

Hi Gary,

The recipe that Jeff's dad adapted from the Four Roses ad was My 
Grandmother's brother's recipe. He submitted the recipe to them in 
some kind of contest and  the four Roses Pr people or who ever 
handled the advertising in those days sent a release for him to sign 
for its use on the bottle and in ads. His name was Dominic 
Gencarelli, he owned a Granite quarry in Rhode Island among other 
things. He was an engineer and figured out a way to build stone 
jettys into the ocean without renting barges and tugboats. His 
Italian stone cutters cut the stone in the quarry in such a way that 
on side the stone was flat and the trucks could drive out on the 
jetty as it was being built. he built a lot of the jettys along the 
east coast especially in New England, but some here on Long Island as 
well.

He always had two bowls of the punch at Christmas , one for the kids 
and one for the grown-ups...here is the recipe., and incidently what 
made the recipe special was its lightness twice as much milk as cream 
and the white of the egg whipped stiff and folded in to the mix , so 
it was almost like clouds on top of the egg nog;

EGG NOG (Uncle Angelo's) 1 batch (6 people)
6 eggs (separated)
1 qt. milk
1 pint cream
1 tbsp. ground nutmeg
3/4 cup sugar
3 oz. bourbon
3 oz. spice rum

Beat egg yolks well until they turn light in color, adding half a cup 
of sugar as you beat. Add milk, cream and liquor to finished yolks. 
Then beat egg whites until they peak. Fold whites into mixture. Grate 
fresh nutmeg over drink.

Cheers

And then a final note from HBD after my posting of this recipe last year:

Subject: Re: Raw Eggs and Salmonella

Brewers

A self described HBD lurker wrote me privately regarding my egg nog recipe:

Thanks for pointing this out.  As a parent, I can only imagine how 
that would affect your feelings.

I continue to use raw eggs in egg nog (and eat sunny egg yolks when I 
occasionally eat fried eggs).  I have based my evaluation of risk on 
Mark Bittman's wonderful newish (1998) cookbook, "How to Cook 
Everything" (winner of multiple cookbook writing awards):

"As for salmonella and eggs: Recent statistics indicate that a small 
number of eggs (about one in ten thousand, or fewer) may contain the 
salmonella bacteria.  If this bacteria multiplies - unlikely in 
refrigerated uncracked eggs - and you eat the egg raw (as you would 
in mayonnaise) or undercooked (as you would in many eggs cooked for 
breakfast), you might become ill, suffering intestinal problems that 
are as bad as the flu.  The very young, very old, or those with 
compromised immune systems may have even worse problems and should 
avoid recipes with raw or undercooked eggs.  But the general 
population should consider eggs safe, and eat them without fear, 
especially if they have been handled properly."

The government, of course, takes the very cautious approach 
http://www.cdc.gov/ncidod/dbmd/diseaseinfo/salment_g.htm, but notes 
that the risk is highest (1 in 10,000) in the northeast.

For less cautious view see http://www.mercola.com/2002/nov/13/eggs.htm.

Happy holidays.

With "only" 60 gallons of wine underway this season, I've got fairly limited options on storage vessels.
  • glass carboys (10 of them). Pros: lots of flexibility for keeping things seperate, press vs free, cab vs cab/merlot cofermentation vs cab/malbec cofermentation, etc. And they're light enough that a person can move them. Cons: you're managing a lot of delicate vessels. No oxygen permeability.
  • barrels (2 of them). Pros: its what the big boys do. "Normal" oxygen permeability. They look cool. Cons: expensive. Heavy. They need maintenance. You need to rotate the wine or blend it between barrels that are new vs neutral, otherwise you over or underoak your wine. Need to top the wine to replenish whats lots to evaporation.
  • Stainless tank (1 or 2 of them). Pros: they last forever, are easy to clean, are durable. Cons: Heavy when full. No oxygen permeability.
I ended up going the carboy route-- only because I didn't have my act together this year, and will end up having to move the wine before next spring's heat hits us. And I don't have a forklift. :) (Plus between my wine making friend and I, there was $0 investment to go this route.) Otherwise I would have likely gone the variable volume stainles tank route. Why the tank and not the barrel? I was on the fence about it-- having never managed a barrel, it seemed it'd be a good learning experience. However I'd have to buy a 30 gallon new barrel and 30 gallon neutral barrel right off. Then hope 50/50 new/neutral oak turned out to be too little, so I can adjust up as needed with oak chips. Then scrape, sulfur, soak, and repeat each year until they're spent and rotate in a new barrel. Just seems like a PITA. The stainless tank tho-- especially the variable volume type like this one don't have any of those annoyances. Problem is, your wine never sees any micro oxygenation, which after 4 years and 8 different wines (from grapes I harvested from both Alexander Valley and Paso) in carboys, I'm convinced is currently a limiting factor for me. And products like the OxBox are likely not priced for amateurs- as evidenced by the fact I can't figure out how much they are.

So tomorrow I'll have the joy of racking and cleaning 10 individual carboys of wine prior to introducing malolactic culture! Early new years resolution: have my friend in the semi-conductor industry build a micro-ox setup and pick up a variable volume stainless tank!

If you're interested in learning more about micro-ox, check out this video: Micro Oxing With Michael Havens.

I've got 4 Cherry Laurels in the backyard. In the past months, just one of them started developing some yellow leaves. Upon inspection, I didn't notice anything obviously different with it and its nearby neighbors, so I turned down the sprinklers thinking they were getting over watered. Things seemed to improve over the summer, but just recently (possibly coinciding with the recent rains?), the yellow leaves have returned. A re-inspection revealed this odd black stuff on the underside of the leaves. The search terms I've tried didn't help- is this mites, a fungus, something else?




The 2007 wine effort consists of 750lbs of Dry Creek grapes. 225lbs in 3 fermenters, one straight up as a control, one cofermenting with 40lb of merlot, one cofermenting with 20lb of malbec. The carboy on the side is is 5 gallons of saignée-- mostly to ensure there's enough space in the vats so the caps don't overflow, but also in order to concentrate the flavors.

They're all fermenting with ICV 0254 yeast, Optired, Lallzyme EX, some yeast nutrient, and DAP added at 10 brix to ensure fermentation completion. Its been about 10 days or so, and they're down to about 4 brix and still going. Should make for a promising vintage!

A little too frothy for my tastes:


Tuesday Sep 04, 2007




In response to Tom's comment, I took a pic of tonight's main course-- using the leftover pizza dough (flatbread really) and some of the remaining pulled pork and BBQ sauce, with a few slivers of red onion. Not attractive, but damn tasty.
