Packet-Yeast Mint Lemonade
Supermarket dry yeast, fresh ginger in the oleo, blanched mint syrup, bottle-conditioned
A variation of Botanically Brewed Mint Lemonade. With supermarket dry yeast and fresh ginger instead of a wild ginger bug
The Botanically Brewed Mint Lemonade made with supermarket ingredients only. Dry baker's yeast from a sachet replaces the wild ginger bug. Fresh ginger goes into the oleo to give the ginger that the bug gave. The oleo with juniper, the blanched mint syrup and the pear juice stay the same. The bottles are ready in about 4 days, not 10. It ends near 7.2% sugar.
Why the first revision
First version of this variation. Aim: the same lemonade with supermarket ingredients and no ginger bug. 0.5 g dry baker's yeast replaces 265 ml of bug liquid. Water replaces the bug volume. 40 g fresh ginger goes into the oleo to replace the ginger that the bug carried. Organic ginger is not needed, because the yeast now comes from the packet. The added sugar is the same as in the ginger bug version. Baker's yeast works faster than a wild bug, so the PET bottle is checked from 12 hours. Not made yet: all sugar, pH and ABV values are calculated or estimated.
Lemon oleo
6 steps-
Peel the zest from 5 lemons in wide strips with a Y-peeler. Take as little white pith as possible.
Tool Y-peeler -
Cut 40 g ginger into thin slices. Crush the slices with the flat side of a knife.
-
Put the zest, the ginger, 100 g sugar and 8 cracked juniper berries in a bowl.
-
Press the mix with a muddler for 1 minute, until the sugar is damp and smells strongly of lemon.
-
Cover the bowl. Keep it at room temperature for 90 minutes.
Time 1.5 h -
Juice the lemons until you have 360 ml. Pass the juice through a fine sieve.
Pulp in the bottle causes gushing when you open it.
Tool Fine sieve
Mint syrup
8 steps-
In the last 20 minutes of the oleo, bring a large pot of water to a full boil.
Work Boiling -
Fill a bowl with ice and water.
-
Put 60 g mint and 20 g peppermint in the boiling water for 10 seconds.
Temp 100 °CWork Blanching -
Move the mint into the ice water at once. Leave it for 1 minute.
Time 1 min -
Lift out the mint. Squeeze it gently dry in a towel.
-
Blend the mint with 35 g sugar and 200 ml ice-cold water on high for 45–60 seconds.
Time 1 minTool Blender -
Let the mint syrup stand for 10 minutes.
Time 10 min -
Strain the syrup through a fine sieve or a nut-milk bag. Press the pulp hard.
The leaves are blanched. Hard pressing adds oil, not a grass taste.
Tool Fine sieveTool Nut-milk bag
Yeast
3 steps-
Sprinkle 0.5 g dry yeast on the water. Stir one time.
-
Leave the yeast for 10 minutes. It must foam.
No foam means the yeast is dead. Use a new sachet.
Time 10 min
Build
6 steps-
Pour the lemon juice over the oleo. Stir for 3–5 minutes, until no sugar grit remains.
Time 3 min–5 min -
Strain out the zest, ginger and juniper. Press them firmly.
Tool Fine sieve -
Mix the lemon syrup, the mint syrup, 200 ml pear juice and 1175 ml water.
-
Taste the base. It must taste slightly too sweet. The yeast uses this extra sugar.
-
Let the base reach about 20 °C before you add the yeast.
A cold base slows the yeast.
Temp 20 °C -
Stir the yeast into the base for 30 seconds.
Condition
5 steps-
Fill swing-top bottles and one PET bottle through a funnel. Leave 3 cm of space at the top.
-
Close the bottles. Keep them at 20–22 °C, out of light.
Temp 21 °C -
From 12 hours, squeeze the PET bottle 2 times each day.
Time 12 h -
Stop when the PET bottle is hard and does not dent. This takes 1–2 days.
Time 1 d–2 d -
Put all the bottles in the fridge at once. Keep them cold for at least 24 hours.
Time 1 dTemp 4 °C
Serve
5 steps-
Open the first bottle slowly over the sink.
-
Pour slowly over large ice. Leave the last 1 cm of sediment in the bottle.
Baker's yeast sediment tastes of bread.
-
Slap 1 mint sprig and put it in the glass.
-
Twist a strip of lemon peel over the glass to release its oil.
-
Keep the lemonade in the fridge. Drink it within 1 week.
Notes
3- 0.5 g dry baker's yeast replaces 265 ml of ginger bug liquid.
- Water replaces the volume of the bug liquid.
- 40 g fresh ginger goes into the oleo. It replaces the ginger that the bug carried.
- Organic, unpeeled ginger is not needed. The ginger is no longer the source of the yeast.
- The sediment stays in the bottle. It tastes of bread.
- The lemon, juniper, mint, pear and sugar are the same.
- The bottles are ready in about 4 days. The bug version takes about 10.
Baker's yeast can carbonate the bottles in 24 hours. Check the PET bottle from 12 hours. When it is hard, move every bottle to the fridge at once. Warm glass bottles that keep fermenting can burst. Open the first bottle over the sink.
Make both versions in the same week. Taste them side by side at the same temperature. Record the difference in ginger depth, sourness and body.
Provenance
Made as a variation of the ginger bug version, for a cook with no bug and only a German supermarket.
The pattern
The plain idea under this dish. Cook it with what you have. The full recipe is on the Method tab.
This is the pattern of Botanically Brewed Mint Lemonade, the dish this one varies.
fresh lemon juice + lemon peel and juniper oleo + blanched mint syrup + sugar + pear juice and water + live culture (ginger bug), fermented in closed bottles then chilled
The parts
6Fresh lemon juice, 360 ml, finely sieved (about 18% of the volume)
Gives the sour taste and the main lemon flavour. Sieving removes pulp, which makes bottles gush.
Oleo saccharum: zest of 5 lemons and 8 cracked juniper berries pressed with 100 g sugar, rested 90 minutes
The sugar pulls oil out of the peel. This gives a strong lemon smell that juice alone does not give. Juniper adds depth inside the lemon.
Mint syrup: 60 g spearmint and 20 g peppermint leaves, blanched 10 seconds, blended with 35 g sugar and 200 ml ice-cold water, strained
Strong fresh mint. Blanching stops the grass taste and browning. Peppermint adds the cold.
White sugar, 207 g in total (72 g feeds the ginger bug, 100 g in the oleo, 35 g in the mint syrup)
Sweetens the drink and feeds the yeast that makes the gas. The base starts near 8.4% fermentable sugar and ends near 7.4%.
Cloudy 100% pear juice (200 ml in the build) and filtered water (930 ml in the build)
Pear gives balance and body. Water makes up the volume to 2 L.
265 ml strained liquid from a wild ginger bug, added 6–12 hours after its last feed
Live yeast that ferments some of the sugar in the closed bottle and makes the gas. It also adds a yeasty, lightly sour ginger note.
- !SAFETY Swap: 0.5 g supermarket dry baker's yeast (Trockenhefe, about 1/8 teaspoon) in place of the 265 ml ginger bug liquid, as in the packet-yeast-mint-lemonade variationBloom 0.5 g dry yeast in 20 ml water at 35 °C for 10 minutes. It must foam. Use 1175 ml water in the build, not 930 ml. Put 40 g fresh ginger, sliced and crushed, into the oleo. Keep the oleo sugar at 100 g and the mint sugar at 35 g. The yeast works faster. Check the PET bottle from 12 hours, 2 times each day. The bottles are ready in 1 to 2 days, not 2 to 4. When the PET bottle is hard, move every bottle to the fridge at once. Warm glass bottles can burst. The flavour loses the lactic ginger note.
The basic method
8- Start the ginger bug 5–7 days ahead: 270 ml water, 65 ml pear juice, 20 g grated unpeeled organic ginger and 20 g sugar in a jar under a cloth at 20–24 °C. Feed it 13 g ginger and 13 g sugar each day. It is ready when it fizzes when you stir it.
- Press the zest of 5 lemons with 100 g sugar and 8 cracked juniper berries for 1 minute. Cover and leave for 90 minutes.
- Blanch 60 g spearmint and 20 g peppermint for 10 seconds. Put them in ice water for 1 minute. Blend with 35 g sugar and 200 ml ice-cold water for 45–60 seconds. Strain.
- Juice the lemons to 360 ml and sieve the juice. Stir the juice into the oleo until no sugar grit remains. Strain out the zest and juniper.
- Mix the lemon syrup, the mint syrup, 200 ml pear juice and 930 ml water. At about 20 °C, stir in 265 ml strained bug liquid.
- Fill pressure-rated swing-top bottles and one PET bottle. Leave 3 cm of space at the top. Close them. Keep them at 20–22 °C, out of light.
- Squeeze the PET bottle each day from 24 hours. When it is hard and does not dent (2–4 days), put all the bottles in the fridge at once for at least 24 hours.
- Open the first bottle slowly over the sink. Keep the lemonade cold and drink it within 1 week.
What the full recipe adds
The full recipe explains each control. The bug goes in at its peak, 6–12 hours after a feed, because the base is very acidic (estimated pH 2.6–2.9) and a weak bug can stall. The carbonation is calculated: about 20 g sugar in 2 L makes about 2.5 volumes of CO2. The mint stays out of the bug jar because venting gas carries aroma away. Blanching stops the enzymes that make a grass taste and brown colour. Filtered water keeps the acid sharp, because hard Berlin tap water neutralises part of it. Citral decays in acid, which sets the 1-week drinking window. All sugar, pH and alcohol values are calculated, not measured, and the record asks for the first batch to be measured.
The science
4What is actually happening in the dish, and why the techniques work.
Supermarket dry yeast is a bread strain of Saccharomyces cerevisiae. It is bred to make CO2 fast in dough.
The lemonade is very acidic: estimated pH 2.6–2.9, not measured. The acid slows the yeast. A small dose keeps the rate slow enough to catch the bottles at the correct pressure.
The dose does not limit how much sugar the yeast can ferment. Time and temperature do. The fridge is the stop.
A large dose, or a long warm time, gives bread and sulfur notes.
Drying damages the cell membranes of the yeast. Warm water lets the membranes recover before the yeast meets acid and cold. The foam also proves that the yeast is alive before it goes into 2 L of lemonade.
The sugar pulls juice and oil from the crushed ginger, the same way it pulls oil from the peel.
Raw ginger gives [6]-gingerol. Gingerol activates TRPV1, the heat receptor, so it reads as warmth. Heat changes gingerol into shogaol, which is sharper. This recipe uses no heat, so the ginger stays warm and round.
The ginger is not fermented. This version does not have the yeasty, lactic ginger note of the bug version. That note is the main difference in taste.
The base starts near 165 g fermentable sugar in 2 L (8.2%). The bug version starts slightly higher because the bug liquid carries some sugar.
About 2.5 volumes of CO2 need about 20 g sugar in 2 L. The base ends near 145 g (7.2%). The ethanol is about 0.5–0.7% ABV.
All of these values are calculated. Nobody measured them yet.
