    10mm female steam tip options?

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi all

    I have a Bezzera BZ-99 and really disliked the stock 4-hole steam tip (the holes are angled out quite sharply which makes it very hard to control the direction the milk moves in the jug) so I bought a 2-hole tip from Jetblack Espresso. I don't like this particular 2-hole either (holes too big and I don't like the alignment), but I'm not finding many other 10mm female thread options.

    I know that technique is everything with microfoaming, but I've used 4 other tips (single hole, 3 hole on a Slayer, that really expensive blade tip one and a Marzocco GS3 tip) over the years and had no problems creating silky microfoam with any of them. Whereas the two I've tried on my Bezzera I just can't hit perfection no matter how many times I try.

    Anyone know of other options? I'd probably prefer a single hole but a well-aligned 3 hole would be fine too...

    Same route - BZ99, disliked 4 hole, bought 2 holer, disliked, rammed a toothpick in one of the holes of the 2-holer, snapped it off so the hole is blocked, and love it. Lovely fast whirlpool, foolproof silky microfoam.

    Also had trouble with a mate's Isomac Tea Due, so did he. Did the same thing and he loves it too now.

    I don't quite understand why machines don't come standard with a one-holer - it's definitely easier for those starting out.

    I had a laugh... I previously jammed toothpicks in two holes on the 4-hole and got great results instantly, but after several weeks it became a problem because of gunk build-up. Maybe I'll try it with my 2-hole though and see if I can get a nice clean insertion so it won't become a problem down the track.

    If I had a soldering iron maybe I could fill one of the hole properly... maybe something to try when I'm at my dad's house sometime.

    It's not even a 'starting out' problem to be honest - I've been able to microfoam and pour some very nice latte art on three different machines with four different steam tips over the past several years... it's only these two tips and the angle that their holes point that have me stumped. I can get foam that many people would consider acceptable, just not true mirror-finish microfoam that I need to pour tulips and rosettas.

    I've always found my BZ99 a bit challenging when it comes to milk. I went from the almost unusable 4 hole to the two hole, which is better (but still average). Lack of a ball joint on the wand doesn't help either.

    I found little for sale retail but I'm buying a mini lathe soon and plan to try making one myself.

    Actually you bring up something important MrJack - I forgot I changed my steam wand to one with a ball joint. You can also buy blank tips that fit the BZ99 that you only need to drill out, rather than having to lathe one from scratch.

    I thought gunk would be a problem with the toothpicks, but it hasn't been.

    I have just gone back to the 4 hole in the last week (which has a greater total hole area), trying to get steaming done quicker and conquer what I assume is more a rumbling technique than a whirlpool, but likewise, I get the foam I typically get at average cafes, not the velvety mirror finish stuff I get with the single hole.

    10mm female steam tip options?

    On my Strega I had Rick the coffee machinest change the wand (ball joint down) to a rocket model so I had more options for tips. Maybe something you can do? I think the wand was $70 now I can use the male tips rather than the rarer (in my exp) female ones.

    Does anyone know if Silvias use a 10mm female thread? I thought I saw someone advertising a single-hole Silvia tip and saying it would fit a Bezzera. If that was the case I could just pick up one of them and be done with it.

    Same problem I got as well with my BZ99. Put three tooth picks in and now it's working great!
    mrfurion I'm thinking of getting this Rancilio Silvia Single Hole Steam Tip

    is changing a steam tip difficult?

    It just unthreads - simple. Might be a bit tight if you've never done it before though...

    I find a damp cloth helps for grip.

    I did a latte art workshop at DiBartoli's many years ago to learn how to steam on the BZ99 (a newb). Unfortunately the BZ99 I was allocated at the workshop had a leaky grouphead and I had to swap machines. The new machine was much easier and I went back home still not being able to steam on the BZ99.

    Tried the toothpick in my two hole tip. Much easier to whirlpool, nicely textured milk. A great stopgap! Also helped confirm for me that going to a single hole tip is worthwhile.

    The problem I've had with toothpicks to change the direction of steam is that it seems to mess up the pressure. As in, I get very little steam pressure even when the steam tap is fully open if I've blocked up holes in my steam tip. Maybe there's a steam pressure release mechanism or something because I should be getting strong pressure out one hole if I've blocked up the other, but I don't.

    Time to try a single-hole Silvia tip I think.

    Single hole Silvia works great!

    I'd hazard a guess your issue isn't pressure - but flow.

    The flowrate of steam through a hole (aka orifice) is a function of the upstream and downstream pressure, and the hole area.

    When you reduce the total hole area (say, by blocking a hole with a toothpick), you reduce the total flowrate of steam (which is kind of the point).

    You're right of course, MrJack.

    Anyway, I picked up a single-hole Silvia tip from Coffe-a-roma in Melbourne today and on my first attempt produced perfect microfoam and a very nice rosetta. So I think that's the way to go for the BZ99 if you're not enjoying the default four-hole.

    Thanks for the feedback on the single hole tip. Will have to get one!

    I did find that the single-hole tip I bought choked the flow of steam too much, so while I was getting great microfoam it was taking as long as my old Gaggia Classic. I solved this by boring out the hole a bit with a very narrow round file... now I get the great directional control from the single tip but also commercial-level flow which allows me to create silky microfoam in 15 seconds or so.
