The New Zealand Pilsner recipe I created is also fairly straightforward with 10 pounds of malt (90% Weyermann Pilsner and 10% Weyermann Carafoam) and 3 hop additions, each split equally between Nelson Sauvin and Southern Cross. The Nelson hops gave an interesting aroma of white wine fruitiness but also more dank and musty aroma than I'm used to while the Southern Cross gave more classic new world hop aromas of citrus and pine. I haven’t used Southern Cross before so it will be interesting to see what this blend gives in the beer. I used filtered water off of MDHB’s hose, hopefully that gives similar results to using my campden treated tap water. I did acidify both the mash and sparge, with 20 mL of 10% phosphoric acid in the mash and 5mL in the sparge.

After the boil the beer was chilled to 175 and the last hop addition was added. After about 20 minutes the temp had fallen to 160 and I started the chiller again to bring it down the rest of the way. Once the wort reached ~75F I transferred to a 6 gallon better bottle and placed it in the car.
After finishing cleanup (and trying a few more beers) I headed home and placed the carboy in the chest freezer at 50F and attached the temperature probe to the carboy. Checking on it late that night it had reached 52F so I pitched the yeast cake of Imperial Yeast Harvest from my Malt Harvest Pilsner.
Tasting:
Smell: moderate citrus, grass, and pine from the hops mingle with moderately-low bready malt.
Appearance: pale gold, just a touch darker than straw. Moderate white head shows moderate retention as it lasts throughout and leaves great lacing.
Taste: Hoppiness leads with grapefruit, pine, white grape, and herbs, middle is lightly sweet and bready with a hard to describe harshness and slickness that then transitions to a very lightly fruity finish with moderately high bitterness that lingers with a citrus rind character.
Mouthfeel: the beer is mostly clean and crisp but seems to have some light astringency and maybe a slight diacetyl slickness in the middle, though neither are offputting or entirely out of style for a pilsner. Drier than expected/intended but well carbonated.
Overall: after a week in the Balkans drinking lots of pale lagers this beer is both similar and very different to European Pilsners. The fruitiness and bitterness are both nowhere near IPA levels but much higher than a standard pils, but the malt character and even some of the roughness in the middle are very similar to continental pale lagers, especially a few Croatian and Slovenian Pilsners I had last week. Part of me wants this to be a cleaner, less fruity beer and another part wishes I had used fruitier hops and dry hopped it. I’m not sure if the beer is to style or not as I don’t remember having a New Zealand Pilsner when I visited New Zealand but it certainly seems to fall within the right range and it’s a perfectly drinkable beer but it doesn’t quite pop as being “New Zealand”-y or “Pilsner”-y to me. Were I to brew this style again I would likely use less boil hops, more post-boil hops (including some dry hops) and replace the more American seeming Southern Cross with a more tropical or white wine like hop (e.g. Motueka, Galaxy, or just more Nelson).
5/7/23: bubbling away nicely with a large dense white krausen. Hoping to turn this one around in about two weeks so I’ll need to do a quick lager method and get this one to the point of a diacetyl rest by next weekend.
5/11/23: gravity down to 1.024. Tastes pretty good though it has a fairly high sulfur smell, likely from the lager yeast though the Nelson's mustiness might also be adding to it. Very hazy at this point but it is still fermenting. Moved out of keezer and onto basement floor with ambient temperature measuring around 64F. Will leave here for a diacetyl rest until fermentation completes.
5/15/23: gravity reading shows 1.009, a few points lower than expected FG, even after taking into account the lower OG. Less hazy though still far from clear. Flavor and taste are largely unchanged, still somewhat sulfury with a moderate fruity and bitter hop character. I'm a little worried that what I've been thinking of as sulfury is potentially light-struck/skunked character due to the carboy sitting out in the sun for a while before packing up and taking it home. There seems to be disagreement over whether wort can be light-struck but either way there's nothing to be done about it now but wait and see. Will likely move to the chest freezer for a cold crash in the next day or two and keg by this weekend. The planned dry hop addition will likely be added to the keg, if at all. I also might split some of this batch off onto vegan ice cream powder for a club competition.
5/21/23: kegged and placed in chest freezer at 30PSI and 32F. Plan to decrease CO2 and increase temperature over next few days.

5/23/23: Base beer appears to be just about carbonated now. Aroma and flavor are fruity with some grapefruit, grass, pine, and white grape, but the character has started to fade. There is also some sulfur character still lingering and the bitterness is a touch harsher than I would like but both seem to have rounded out some with the carbonation.
6/6/23: tasting notes of the base beer above.
6/10/23: decided to finally add the dry hop addition to the keg
6/15/23: hops seem to have caused some hop creep and diacetyl so I’ve pulled this from the chest freezer to hopefully clean it up.
6/19/23: moved back to chest freezer. Still light diacetyl but back into a similar range it was previously in.
6/24/23: this one kicked as I filled a growler for a homebrew club meeting. Pretty well received, I saw a few people go back for seconds.
